“Our experienced engineers will assist you to deal with various types of complex engineering projects”

Ballast Water Treatment SystemsFeasibility & Engineering studies

Retrofitting StudiesWe offer comprehensive turnkey solution packages for the selection and installation of various marine equipment.

We can ensure that the selection of the appropriate

marine equipment and the pertinent installation shall

meet the diverse needs regarding to each ship’s spe-

cific operational conditions and the related legislation

requirements, respectively.

Among the great number of regulations and available

technological solutions arises the need for a coopera-

tion with a partner with deep knowledge of the bal-

last water treatment process and requirements.

We prepare a techno-economic study for BWTS mak-

ing the initial selection easier for the ship Owner being

able to compare all the pros and cons of the pertinent

systems. Various parameters are considered including

CAPEX & OPEX.

Challenges of feasibility:• Selection of the most suitable location.

• Footprint & availability of maintenance space.

• Clash-free movement of large components

• Pressure drop and ballast pump capacity

• Securing of vessel’s normal operation.

• Minimization of the necessary modifications on the

existing piping systems and structural members.

Our experienced engineers carry out surveys on board and witha3D-La-

ser Scanner perform a full scan of the vessel’s preselected areas

which will be fully illustrated into a 3D point cloud. With 3D-Laser Scan-

ning you avoid the risks associated with manual measurement

and fabrication on board as you have a comprehensive view of all the

scanned areas.

as Owners’ preselected marine solutions for overview

and better evaluation.

Subsequently, an iterative process is being followed,

by modelling the existing piping and incorporat-

Α clash detection process is performed for every sys-

tem in order to minimize any interference with existing

structure and outfitting arrangement.

We deliver a full feasibility report and afterwards

the Owner can easily make the final selection of the

system in order to proceed with the engineering study

and complete the installation process.
