Objective
Closing the gap on carbon regulations.
With our exclusive principal CMES-Tech and the towing tanks of CSSRC, we apply pioneer hydrodynamic technologies that lead the energy efficiency sector — each device designed around the vessel it will be fitted to.
Evaluate
In-depth fleet evaluation.
A full technical and operational evaluation of each vessel’s energy profile, working with you to establish its current compliance status. Our contacts network lets us trace missing drawings and documents, which often decides the best result.

Solutions
Energy saving technologies.
Energy upgrades are the method followed worldwide to improve EEXI and CII ratings. Three devices work together around the propeller; each is sized for the vessel after CFD evaluation.

Pre-Shrouded Vanes
PSVVanes in a duct ahead of the propeller that pre-swirl the flow onto the blades.

Wind-assisted propulsion
Wind-assist systems installed on deck.
Tailored engineering
A complete turn-key process.
From selecting the solution to EEXI verification: six engineered stages, one accountable partner.
1
CFD evaluation
Computational fluid dynamics
Input data is collected for a first CFD evaluation. The most suitable devices for the vessel are presented in a preliminary energy-saving report.
2
SBD optimisation
Simulation-based design
Once the solution is chosen, the design is tailored to the vessel’s specific needs and operating profile through simulation-based design.
3
Model tests
Deep-water tank validation
The final design is built at scale with the vessel’s complete hull model and tested in CSSRC’s deep-water towing tank, validating performance for class approval.
4
Production
Class-approved manufacturing
Devices are fabricated from the highest-quality materials in the shortest lead time available, and structurally certified by class before delivery.
5
Installation
On-site supervision
Products arrive at the shipyard ready to fit; our engineers supervise on site. Trailing-edge trimming is done in situ to class-approved drawings.
6
Verification
Performance verification
Sailing records confirm the actual saving. The EEXI technical file and RightShip GHG rating are updated with the model-test results.
