Summary of Summer Internship Enya Mc Hale

May/June 2016

What I did:During my time in Qatargas (QG), I was able to work with many people and be exposed to different aspects of the Sales Admin (SA) department and the Commercial and Shipping Group as a whole. The Sales Admin department implements and manages the contracts for LNG & Associated products, as well as some contract development. They are the main focal point for customer management.

Meetings:• During my time in SA, I was given the opportunity to attend

a multitude of meetings:( SharePoint( iContribute( Staff meetingo Presented the safety moment during the June meeting

( Weekly Heads meeting( Weekly optimization meeting( Laffan Refinery 2 condensate meetings( Different department overviewso Marketingo Shipping

Gail: Controls AdvisorEnsures department governance is effectively in place – e.g. implements and manages the controls calendar and all procedure of the department along with integration of a SharePoint system.• Was able to shadow Gail:

( Attend meetings on SharePoint( review controls calendar ( Introduced to procedures

Milton and Andre: Commercial AdvisorsRepresent the LNG ventures in negotiation, development, interpretation and ongoing stewardship of many agreements essential to operations.• Was able to attend meetings with Milton and Andre

( Attended meetings related to Laffan Refinery 2 condensate sales

Shane: Head of LNG Contract Optimization and Business SupportThe SA focal point for LNG contract optimization and development, includes contract reviews and development of standards, policy guidelines and procedures. • Was able to work with Shane on the LNG BTU project:

( Tested BTU models( Analysed data( Developed Excel skillso Built tables and pivot tables for analysis o Built tables for summaries

( Interpreted LNG sales contracts for BTU inputs( Utilised LNG surveyor reports and industry reference standards

LNG BTU Model Testing:

QG delivery approximately 500 LNG cargoes per year to customers and the BTU model is a key model that is used to calculate the energy delivered of the LNG. It is called the BTU model as the energy delivered is measured in energy as MMBtu’s.

Many readings are taken from an LNG vessel and from the sampling equipment at the terminal to help determine the volume of LNG and its chemical composition. An independent expert called an LNG surveyor validates these results. A technical schedule in the sales contract is then followed to calculated the energy delivered using all of the readings.

Using QG contracts I tested a pre-established model to ensure it was working and giving the same results as the LNG surveyors report gave. If it did not match I looked for ways to correct the issue.

Activities summary:• Excel analysis of contracts, vessel readings and LNG laboratory results to

validate and correct a pre-existing model • Reviewed previously inputted reference standards to check they were all

inputted correctly (e.g. ISO 6976)• Checked the model was following the sales contracts - methodology used,

rounding's etc.• Gained an understanding into how LNG contracts work• Gained an understanding of BTU calculations and their application• Required great attention to detail and excel analysis/problem solving skillsPage 3

LNG BTU Model Project:

The aim of the project is to analyse contract set-up changes that could result in a financial difference, e.g. using a different calculation method, reference standard or rounding could make a considerable difference to the amount of LNG delivered to a customer.

This is achieved by creating a bespoke QG model evaluating all the possible deviations from the QG standard Master sales agreement (used for short term deals). Using a years worth of valid cargo data we can see the resultant effect of different situations.

I helped work on the LNG BTU model project by assisting in the set-up of the data by analysing through checks and table building. I also built summary tables needed for the final report though the use of pivot tables.

Activities summary:• Reviewed previously inputted reference standards to check

all inputted correctly• Gained an understanding of BTU calculations and their

application• Excel analysis of contracts and lab results to validate and

correct a pre-existing model • Using a years worth of cargo data inputted checks and

conditional formatting to allow for a clean-up set of data to be identified

• Created a multitude of tables, pivot tables allowing for min, mean, mode, max and average to be calculated

• Created tabs to be utilised to analysis the cargo data clearly• Assisted in the creation of a report to summarise the results

A BTU calculation is complex calculation used to determine the energy of a delivered LNG cargo. In a BTU calculation there are several factors that can be changed such as the volume of LNG, reference standards, the rounding and the temperatures and pressure during the voyage. All of these have an effect on the resultant energy (MMBTU) calculated, therefore by manipulating each one we can see its direct financial effect.

Skills and Competences:

During my time with QG I have been able to develop and enhance my skills and competences through my experiences:

Skills and competences developed:

• Analysis( Analysis of a years worth of cargo data and creating checks

to evaluate the validity of the data• Organization
