APETT Technical Conference 2016 – Innovative Engineering Solutions
for the Caribbean
The opening address for the conference was done by the
Conference Chair and APETT Vice-President Eng. Dr. Chris
Maharaj. He welcomed and thanked the respective sponsors
and participants for their contributions to the event. The
conference welcome was then given by Eng. Fazir Khan,
APETT President and Conference Advisor and was followed
by the principal of the University of the West Indies, Professor
Brian Copeland, a fellow engineer, giving the keynote
address.
The Pro Vice-Chancellor and Campus Principal Designate
gave his definition of innovation as the process of translating
an idea or invention into a good or service that creates value
for which customers will pay. He explained that there are three keys to innovation; economic,
social and ecological. Professor Copeland used the example of the Percussive Harmonic
Instrument (PHI), and showed many other examples of
where innovation was needed in our society. He
proposed a National Innovation System to motivate,
protect and reward creative ideas as not enough was
being done, in his opinion, to endorse innovation. Giving
many reasons as to why the Caribbean should indeed
invest in innovation, and pointing out the fact that the
University of the West Indies‟ Faculty of Engineering,
alone, produces 150 projects per year, he showed how
the culture and mindset of people are already beginning
to change, as more and more people seek to produce
commercially viable creations. He concluded by stating
that he intends to create an atmosphere of this sort,
during his tenure as Campus Principal, encouraging
Day 1
everyone in the audience to create an innovation rich Caribbean.
The first feature speaker of the event, H.E. Fernando Schmidt, Ambassador of Chile to
Trinidad and Tobago, started the conference by presenting on the “Development of Solar
Energy in Chile”. However, he also spoke about the unlocked
potential for geothermal, biomass and wind energy in his
country. His discussion highlighted that approximately 20%
of Chile‟s energy is currently being produced by renewable
energy methods and that up to 60% of the country‟s subway
system is run using this. Chile, like many of the Caribbean
countries, agreed to Paris COP21 and as such, national
policies were set by NGO‟s, without government subsidies, to propel this motion. He claimed
that our islands should adopt similar practices if we are to meet the initial targets set (20% for
the Caribbean) by 2017.
The succeeding International Forum Feature Speaker,
H.E. Mitsuhiko Okada, Ambassador of Japan to
Trinidad and Tobago, presented his report on “Japan‟s
response towards the creation of a sustainable and
resilient society.” This report was particularly directed to
the resistance of buildings to earthquakes and tsunamis.
His research indicated that 88% of casualties that occur
after an earthquake is related to the collapse of buildings or homes. However, the number of
quake resistant houses have been increased from 82% to 95% since 1980, through the
practices of Tsunami Detection and Resilient Infrastructure. He further explained that Japan will
provide USD $12 billion to developing countries, including Jamaica, Barbados, St. Kitts and
Trinidad and Tobago, and over the next five years, will provide up to USD $200 billion dollars for
quality infrastructure investments, worldwide.
After the coffee break, the conference was divided into two groups where simultaneous
discussions were held. The first group, focused on Innovations in Processes, where the first
speaker, Mr.Christopher Fullerton of (previously) Arcelor Mittal Point Lisas Ltd., discussed
“Improvement in Operations at a steel manufacturing melt shop.” He was able to identify points
where the waste occurs in the process. This was; during work-in-progress and during the
continuous casting processes. He indicated that the company was performing at standards
below those of the international „best practice‟ standard. As such, he suggested the
implementation of 5S (Shine, Sort, Sustain, Standardize, Set in order), TPM (Total Productive
Maintenance) and Production Smoothening. The study showed that implementing these
practices would reduce the set up time and then he used a computer simulation to validate his
study. Recommendations were suggested to conduct a nationwide survey into Lean
Manufacturing.
Mr. Roger Camacho, a consultant with over thirty-five years of experience, was able to deliver
for the next discussion “Some examples of innovative projects in the manufacturing sector in
Trinidad and Tobago.” Four examples highlighted are
Use of chill water air handling unit as a cooling tower
The modification of four colour flexographic printing press to print 5 (or more) colours
The electronic window patch detection system
A management system to eliminate tool pilferage
The first project occurred due to a low water supply
at the plant where he worked, which then lead to
downtime of the equipment and increased costs to
supply water. Mr. Camacho was able to design a
control system that saved the plant “Tens of
thousands of dollars weekly.” The plant requirement
dropped from approximately 15000gallons/day to
2000gallons/week which was an investment that was
paid back in less than three months.
His second and third projects were performed for
envelopes, where (for the second), printing of more
than five colours either could not be done locally, or
was very expensive, as such, the simple idea of
splitting the printing stations came about and was a
low cost, highly effective solution to the problem, that
then gave the company a competitive advantage.
For the third project, the issue occurred because there was no reliable way to detect if the clear
window patch was sticking to the envelope, which led to faulty envelopes and machine
downtime. This issue was rectified by having fiber optic infrared sensors to detect if a patch was
present, by blowing air onto the open sides of the envelope. The new system was able to detect
all envelopes, however, due to the incredible speeds at which the machines moved, the system
overcompensated and would sometimes (<0.4%) remove more envelopes than necessary. The
final project, which was a social one, of tool pilferage, was solved, by simply creating a tool
lending process, which Mr. Camacho claimed to work 100% (in his experience).
On the other hand, the overlapping group addressed
Innovations in Framework/Policy. This group began with a
discussion on the “Use of Satellite Images, Remote Sensing,
Lidar, GIS, Hydrological and Hydraulic Software to Manage
our Environmental Resources Sustainably”, by Dr. Pramenath
Narinesingh of the UWI Department of Civil and
Environmental Engineering. Dr. Narinesingh defined
Sustainable development as, “Growth that meets the needs of
all without endangering the natural resources needed for the
future.”
However, it was learnt from annual reports that dangerous trends in our environmental
resources are constantly depleting. Hence, the Caribbean should implement steps forward and
utilize the present technology as a community and make efficient use of our natural and built
resources. The remote sensing technology and the advancement in geographic information
system makes it easy to capture environmental data rapidly anywhere on the planet and
accurately process it into useful information. Thus, through the integration of information from
satellite and earth observation systems from around the world, better informed decisions may
be made regarding biodiversity and ecosystem sustainability, disaster resilience, sustainable
urban development and water resources management.
Following this presentation, was “Strategies for Developing Sustainable
Transit Connectivity in Diego Martin”, by Dr. Rae J. Furlonge of LF
Systems Ltd., and was presented by Hawwa Hassan of the UWI‟s
Department of Geomatics Engineering. This study investigated the poor
transit connectivity that affects the everyday residents of Diego Martin
and provides meaningful recommendations that would improve the
sustainability of the transit system. It was highlighted that there are not
any resources and facilities that can be utilized firstly before engaging in
more expensive plans of action. From various sources, land use,
transport demand and transport supply are the main aspects affecting transit. Suggestions such
as, social marketing, accessible to schedules/routes, altering peak periods and equipping buses
with Wi-Fi to enhance commuters experience should encourage more residents to use the local
transit.
Heading the final session for the morning, was Dr. Ashton
Rogers of UTT‟s Biomedical Engineering Unit. His delivery was
based on “Improving the storage of electricity produced by
renewable sources.” Dr. Rogers‟ study focuses on the most
recent advancements for electrical energy storage in the form of
Hydrogen. Two main technologies highlighted that produces
hydrogen are solar fuel cells which uses artificial
photosynthesis and water electrolysis with various
improvements such as increased pressure and temperature of
electrolyte as well as wide electrodes in an absolute vertical positions. There are many other
improvements to the basic water electrolysis to produce hydrogen fortunately, they all prove to
be very cost effective and overcome many disadvantages of earlier designs such as low
efficiency and reliability and many more.
After lunch, the groups were further divided, but this time, into the categories of Innovation in
Design and Innovation in Processes. Continuing the Innovation in Processes portion, was Mr.
Ryan Roper of CADPEC Limited. His contribution was on “Optimizing the fermentation period
of Trinidad and Tobago Cocoa beans for chocolate production.” He began by explaining that the
native Trinitario Bean comprises of a mixture the Creole and Foresto Beans and that the
potential products for it was not just chocolate, but also for cosmetics, paper and cocoa powder
too. He highlighted that that the value of the beans depended on the fermentation. Most farmers
rely on intuition and weather patterns, to determine if they think the fermentation process is
complete.
Mr. Roper suggested that temperature and pH levels, or
other measured variables could be used instead. He
suggested that a mandate or business model be
developed and that they work with the UWI Cocoa
Research Center, as there is an abundance of
information available there. However, a gap exists
between educating the farmers on the results of research conducted, as more theoretical
approach is used, whereas the farmers prefer a practical one.
Mr. Areo Hosein a student of the University of the West Indies
presented his findings on the “Additional of waste polymers in road
surfaces of T&T.” He identified the various layers of the road, paying
attention to the composition of the surface layer, and showing the
problems that occur. These were found to be mainly; rutting and
cracking. His project involved the addition of varying compositions of
PET (polyethylene therepthalate) and CR (crumb rubber). Marshall
Stability and Marshal Flow tests were then performed on the new
mixtures and it was found that the PET mixture produced better results
when compared to the crumb rubber, having the higher stability and the lower flow.
Mr. Andrew Castor of PCS Nitrogen delved into “An investigation into the efficiency of
chlorinators in preventing biofilm buildup in seawater cooling systems at the Point Lisas
Industrial Estate.” The issue that was occurring was an amassing of biological fouling in the
pipes, reducing its surface area and insulating the pipe so cooling could no longer occur. His
solution was – chlorination. It is simple, low cost, available and effective. He recommends that
there be an increase in current supplied to the cells, increase the number of cells available for
production of a hypochlorite and add a dripline for the chlorine directly.
In the Innovation in Design sessions, “The Quadric-Surfaced Sledge Digester for Developing
Caribbean Countries”, was prepared by Mr. Navin Ramroop of
UTT‟s Department of Project Management and Civil
Infrastructure. Mr. Ramroop‟s paper outlined the ongoing
research as well as the benefits of the Quadric Surfaced or egg-
shaped sludge digester (ESD). The ESD is said to be the most
efficient and cost effective secondary treatment of wastewater
sludge. Due to its parabola shape, it has proven to be most
efficient in scraping at the base of the tank hence, producing a
cost saving mechanism. Unfortunately, construction of tanks are
very costly since it requires highly skilled labourers to assemble. Thus, the study investigates
techniques involving 3D printing which achieves the similar results to that of the concrete tanks.
Ms. Kristal Sookdeo of the UWI‟s Department of Mechanical and
Manufacturing Engineering, demonstrated the “Improvement of
Cassava Harvester using TRIZ”. Her final year project consisted of
improvements made to a cassava harvester by applying the method
of TRIZ, a problem solving method based on logic and data in which
the propose is to find superior solutions, to overcome the need for a
compromise between two elements. After applying the method of
TRIZ, the working depth of the crop harvester was increased which
allowed the improvement of loosening the soil capabilities without
damaging the produce.
Mr. Roger Mylan also from the UWI presented, on “Creating the Optimal Product Formula for
use by a Heavy Clay Block Manufacturer.” Mr. Roger investigated the possible root causes for
major quality defects such as cracking, excessive shrinkage and
unsatisfactory colour in clay blocks manufactured in Trinidad by looking
at the non-optimization of the block ingredients. Scanning Electron
Microscopy (SEM) and energy dispersive x-ray spectroscopy was
conducted to measure the efficiency of mixing in the preparation of the
blends along with the elemental composition and distribution at the
surface.
After the coffee break, Ms. Cheryon Morin of the UWI led the final
lectures on Innovation in Processes. Her discourse on the “Reuse of
slag in the surface of road pavements,” showed how the ferrous smelting
byproduct could be reused, as opposed to being disposed of and contributing to environmental
degradation. The study varied the composition of electric arc furnace steel slag from 0% - 20%
of ¾ inch aggregates, and was then verified using Marshall Stability and durability tests.
Accelerated weathering and comparison testing showed that the optimal slag content of 4%
increased the mechanical properties of the road pavement by increasing its stability and its
ability to withstand stronger forces.
Ms. Helena Ali-Victor of the UTT presented her findings on “Optimising
conditions for maximum adsorption of greenhouse gases using zeolite
and hydrotalcite in packed bed columns.” As Trinidad is a large oil and
gas exporter, it is imperative to note that many greenhouse gases are emitted as our industrial
processes are carried out. This project aimed to directly reduce emissions in order to reduce
their effects (increased temperatures and sea level rise). Three main pollutants were targeted –
CO2, SO2 and NO. The process of adsorption, using zeolites, (SiO4)4- and (AlO4)
5- and
hydrotalcite, was investigated and compared to other methods (like MEA scrubbing systems) to
determine if it was more economical and to ensure that it did not replace one pollutant for
another since adsorbents usually have resultants that are contaminants also. Although the
actual experiments were not yet carried out, the phases of the experimental procedure and
response surface methodology were presented.
The adjacent gatherings however, reverted to the Innovation in
Design categories. “Life Cycle Cost Analysis (LCCA) of Vapor
Compression Cooling (VCC) vs. Vapor Absorption Cooling (VAC)
for Chiller Plant in the Range of RT: Case study for T&T”, was
conducted by Mr. Daryl Joseph of Energy Dynamics Ltd. He
explained that, due to the fact that Air conditioning is becoming an
important utility, much like electricity and other services, a study
was conducted to determine the Life cycle cost analysis for the Vapour compression cooling VS.
Vapour absorption cooling. The study investigated whether the VAC was more economical than
the VCC by comparing the life cycle cost of the chiller plant ranging from 50-400 RT. The results
from various analysis showed that the VAC system was capable of being the feasible economic
option to provide cooling for buildings. Additionally, the VAC systems were proven to have less
environmental impacts when compared to VCC systems.
Concluding the day‟s presentations, was Dr. Denver Cheddie of the UTT‟s Utilities Engineering
Department, on “Domestic Wastewater Treatment and Associated Biogas Generation using
Anaerobic Granular Bed Baffled Reactor (GRABBR).” Dr. Cheddie‟s
project assessed a pilot scale anaerobic granular bed baffled reactor for
domestic wastewater treatments at high organic loading rates under
varying temperatures with the associated biogas production. The
applications of GRABBR as a single unit, two phase treatment system
could be an economical option reducing the cost to achieve similar
treatment goals for high strength waste waters. The findings of this
research suggested that the application of GRABBR is indeed suitable for the treatment of
multiple pollutants present in domestic wastewater where each compartment act as a
specialized treatment stage with equivalent biogas production.
Concluding the day, the final feature speaker, H.E. Mr. Gauri Shankar Gupta, High
Commissioner of India to Trinidad and Tobago lectured the
audience on “Sustainable Development.” He spoke of making
a better lives for the future by using only what we need and
nothing more. He explained that our society has become
wasteful and distant from nature and recommended that we
need to go back to it. He suggested that governments impose
limitations for societies that will allow them to meet the needs
of it without jeopardizing the future society‟s and that the
wealthier classes do more to share what they have. He cited
many examples of this being done in his country and how it can be incorporated into ours, finally
stating that it doesn‟t matter how much we speak about it, unless nothing is done about it, it
would all be for nothing.
The following day started with a feature
sponsored speaker on behalf of the Canadian
High Commission, Mr. Glen Sharp on the
“Engineering Design/ Engineered Wetlands
construction management.” As someone who
had overseen this project‟s development in his
country, Mr. Sharp had showed its success and
offered proposals to companies such as Yara
and SWMCOL suggesting that the same could
be done here. That is, a specially designed
wetland, with specific plants being grown at an
Day 2
area, such as a delta, where there is a large amount of effluents leaking into the ocean. His
presentation showed how the wetlands will act as a filter and help reduce the effects of
chemicals as they runoff into the environment.
The IMechE’s Student Chapter Global Engineering Debate (GED) on “Public Transportation
Solutions for the Future” was delivered. The debaters this year consisted of Mr. Kavir Ramdass
(transporting sharing companies/services), Ms. Leanda Bidaisee (alternative fuels and
autonomous/connected vehicles) and
Ms. Leah Wright (improvement to public
transport). The debate chair was Ms.
Onika K Morris Alleyne. The event
started off with a poll to determine what
the audience thought was the solution
themselves, and then each member on
the panel gave a short discourse as to
why their option should be invested in as
oppose to others. After one round and a
few more questions and comments from
the audience, the audience was polled once more and found to have a sway in their vote.
Mr. Bill Ramrattan’s presentation on „Foundations and floors
on expansive clays and compressible soils,” highlighted that
numerous structures in Trinidad are set up on marginal soil
using details that exclude shrinking of clay and the
compressibility of the soils. From various studies, piles and
rafts foundation are found to be the most common to counter
soil factors in Trinidad. Additionally, Mr. Ramrattan gave
insight on using unbounded pre-stressing cables which are
very useful and economical for post tensioning of foundations
for counteracting effects swelling of clays and settlement in
compressible soils. Consequently, the compression that
results from post tensioning counteracts the tension forces
created by subsequent loading and shrinkage of the soil

significantly increases the load carrying capacity of the concrete.
The groups were divided once again after the break, this time to discuss the issues on
Innovation in Design and Innovation in Health. Mr. Ilias Papadopoulos of the UWI‟s
Seismic Research Center started the proceedings with his presentation on “Earthquake Loss
Estimation in the Caribbean.” The seismic research center has initiated the past several years‟
projects, aiming towards the direction of identifying and quantifying the
seismic hazard and risk for the region. In modifying Ergo-EQ, the
researchers are able to statistically classify building structure type using
widely available proxy data sets. The project aims to provide the
resonance frequency and soil classification of the ten major areas in the
country, providing engineers with a useful tool with regards to civil
construction.
Mr. Nishkal George of the UWI‟s Department of Mechanical and Manufacturing Engineering
delivered his findings on the his “Design and Development of the Anatomical Model: Application
of CAD and Rapid Prototyping Principles,” he stated that in the
training for medical practitioners they require provision of fully
comprehensive knowledge of patient-specific anatomy that traditional
models lack considerably. Rapid prototyping and Computer aided
design principles together have the ability to meet the situation by
allowing fabrication of three dimensional anatomical objects which
facilitates first-hand view of the anatomical build of the human body.
Thus, this study explores the used of Genetic algorithm on the
design performance of anatomical CAD models. The results from this
study proved to be successful in producing a RP patella model resulting in 27% material savings
and was deemed satisfactory for practical use.
Mr. Kiran Ragoo, also reported on his final year project findings,
“The Design of a children‟s playground kit to introduce the design
thinking through free play.” Mr Ragoo‟s paper details the design of
a mechanical playground kit that allows children to use their
imagination, physical, cognitive and socialization skills in
assembling the elements. The design supports the critical thinking
of utilizing simple machines covered in the school curriculum, while at the same time instilling a
passion for outdoor activity. He hopes that the design would contribute to building young
designers and a culture of innovation and design through play.
On the Innovation in Health side of things, Ms. Amalia Hosein of
UTT‟s Biomedical Engineering Unit presented her results of
“Testing three cardiovascular disease risk prediction models of the
Trinidad and Tobago population.” She introduced her audience to
the five models used to generally predict CVD, showing that they
are not applicable to us. Genetic variations called SNPs (snips),
were looked at in both CVC and non-CVD patients. The results
found that gene scores did not give good predictions, and the
typical SNPs used, did not either. MIAs and MRAs did and from
this, an ROC curve for risk prediction was created and found to be
more accurate than the previous models used.
Another UTT biomedical student, Ms. Keri Gobin, also looked at a common health issue
affecting Trinidad and Tobago and how to assist in mediating it. “An android app for detection
and self-monitoring of diabetic foot ulcers.” Foot ulcers can be severe, leading to amputation
and handicapabilities. Ms. Gobin‟s innovation was to use an infrared camera, FLIR1, with an
app to send images and data (such as age and glucose levels) to doctors, without patients
having to leave their homes.
Finishing up this section, was the head of the biomedical
department at UTT, Dr. Natasha Ramroop-Singh, on,
“Establishing a new system of biomedical technology
assessment in Trinidad and Tobago.” Dr. Ramroop-Singh
enlightened fellow engineers on how her department
bridges gaps and transcends occupational barriers as there
are multifaceted roles such as designing, repairing and
calibrating machines to name a few. She proposed a TTQ-
MTA (three tier question based medical technology
assessment) system that could be used in a scientific, clinical or business setting. This included
the measurement devices, therapeutic devices and clinical information studies. She suggested
the restructuring of the regional health authority by asking three questions at every venture; Is it
real? Can we win? Is it worth it?
After this presentation came the call for lunch, but diving straight back into the program, was Dr.
Sharad Maharaj of UWI‟s Department of Chemical Engineering, on the “Development of a
Supercritical Fluid Extraction Industry in Trinidad,” for Innovations in Processes.
Essential oils and Oleoresins as well as other plant extracts has grown significantly
over the years, such that trade oils have risen drastically. The traditional extraction
technology is that of steam distillation for essential oils and solvent extraction for the
oleoresins. Fortunately, modern technology of Superficial Fluids extraction using
carbon dioxide, has the capability of producing the both types of products. Once
introduced in Trinidad, the SFE would use the carbon dioxide from the ammonia
industry which is used in the extraction of high value products from plant materials. The
researchers are also looking to introduce the concept to Dominica since bay oils has been
produced by steam distillation for many years.
Subsequent to this, was another member of the UWI‟s Chemical
Engineering Department, Mr. Jeffery Smith, on using “Plastics waste to
petrochemical feedstock.” This presentation highlights alternative
approaches available for the recycling of waste PET including physical,
chemical and energy valorisation options. Due to the drop in value of oil,
Trinidad and Tobago need to reduce the outflows of foreign exchange
from the country. Thus recycling of these plastic bottles could result in
dual benefits of reduction in foreign exchange outflows and negating an
adverse environmental situation.
The final presentation for the conference, on Innovation in Processes, was done by Ms. Maria
Kesse of Herriot-Watt University, on “Waste tyres to Petrochemical
Feedstock.” Industrial symbiosis is focused on the development of
techniques to turn apparent waste into industrial feedstock. Trinidad
and Tobago being a well-developed petrochemical industry would be
capable of receiving as feedstock, breakdown products of vulcanised
rubber and fabric from chemically recovered tyres, due to the fact that
the country has thousands of waste tyres generated per year.
Abandon tyres serve as a serious health hazard as they are potential breeding ground for
insects and vermin.
Adjacent presentations were being delivered on Innovations in Design, and Mr. Kamel Singh
of Energy Dynamics Ltd. discussed, “Expanding opportunities for organic waste producers in
the Dominican Republic to become energy providers, waste treatment operators and organic
fertilizer suppliers.” He spoke of how the high source of methane emissions that comes from
meat and poultry can be used, along with waste treatment technology of anaerobic digestion.
His project proposes centralized co-digestion or a location either centrally or where the largest
waste producers are. He showed that smaller farms have greater difficulty thriving as compared
to larger farms that only focus on one animal rearing, yet between 50-100 head sized farms are
still economically feasible enough using the suggested methods as there are quite a few
incentives, tariffs and subsidies, making it easier to tie into the grid in the Dominican Republic.
Next, Ms. Davatee Maharaj gave a presentation on “Radiation shielding parameters of concrete
made with electric arc furnace slag aggregate.” The energy of radiation and thickness of the
blocks, both help in determining is something can be safely protected. Also, density, which will
increase, due to an increase in atomic number, leads to having
more atoms to react to. Currently, lead is the most common
shielding source used in Trinidad and Tobago, so the aim of this
project, was to find a more cost effective material. Thus, she
compared lead blocks to concrete blocks made with electric arc
furnace slag aggregate (which is an industrial by-product). The
results found that the thickness of the concrete samples had to
be increase to improve the radiation shielding parameters.
Concluding the afternoon processions, was Ms.
Kathryn Maharaj of the UWI‟s Mechanical and
Manufacturing Engineering department, on the, “Design of
a special-effects wrist--mounted flame thrower.” Ms.
Maharaj‟s aim was to show that local isn‟t bad and that
foreign isn‟t better. The device‟s main use was intended to
be Trinidad and Tobago‟s entertainment industry. Although
the objective was to have a 4in high flame in the palm of
the hand, the flame produced was able to reach as high as
3ft.
Changing over to the Innovations in Framework/Policy, Professor St. Clair
King of UWI‟s Department of Electrical and Computer Engineering started
of the presentations after the evening break with “The Engineer in the Fourth Industrial
Revolution.” Fourth Industrial revolution is being driven by extreme automation and connectivity
especially through wider implementation of intelligent systems. Developed economies will most
likely be the winners at this stage whereas developing economies will face a greater challenge
as their low skilled labour would cease and limited technology infrastructure will not reap
benefits of extreme connectivity. Thus, the paper presented elaborates on ideas and
demonstrates the impact the revolution must have on the training and education of fellow
engineers.
Concluding the days discourses, was Dr. Lorrain Sobers of the UWI‟s
Chemical Engineering Department, with, “What does COP21 mean for
Engineering in the Caribbean?”. Dr Sobers‟ paper highlights the
potential for Caribbean SIDs to transition to low carbon economies with
financial and technical support for developing new technologies. The
path towards an ambitious, economy-wide emission reduction, cannot
be done without innovative engineering solutions. Dr. Sobers looked at
numerous Caribbean countries and the respective methods they wish to
implement to gain a more renewable-based economy.
The penultimate discourse for the evening was done by Rheal Thomas of WASA Operation
Division on “Developing software to mimic real world objects in the design of water and sewer
systems.” The aim of the project is to standardize the design process for approval. The solution
was to develop a program where objects were created in JAVA with state and behavior.
Sequencing diagrams were used to accomplish a task pipe flow and then simulations used data
inputs, such as two sample points, and mass balance equations to get a full conditioned
assessment. The program was successful in integrating the structure of objects which enabled
the design and optimization of waste water systems. The validation showed that the system
would save both time and money.
Mr. Lloyd Lynch of the UWI‟s Seismic Research Center delivered the final lecture for the
conference on, “The advanced geophysical monitoring network of the Eastern Caribbean.” His
suggestion for Caribbean tsunami early warning systems is to detect seismic waves first, since
they are faster than the tsunami wave, and relay data via the internet. He divided the project into
four categories;
Warning
Preparedness
Communication
Hazard/impact assessment
His suggestions reduced the detection time to less than one minute, although it may take longer
(up to 5 minutes) to get the information to the public or media. On the other hand, larger
earthquakes take longer to detect, due to their large wavelength and high energy. Additionally,
he recommended having sea level monitoring equipment to assist his project in the future.
The conference concluded with closing remarks by Eng. Imtiaz Easahak, APETT President-
Elect and Conference Advisor, and the distribution of tokens to participants. The IMechE would
like to acknowledge the session chairs, Mr. Jonathan Chang and Mr. Jainarine Bansee, as well
as our debate chair, Eng. Anthony Mathura, along with all other conference committee members
who assisted with the presentations. Overall, the conference was deemed a large success, with
everyone looking forward to attending in the coming years.
