Independent assessment for shipping

Commit capital with confidence, not conjecture

High fidelity assessment of Maritime Energy Saving Technologies

Fuel, emissions and regulatory impact relevant to your vessel and routes

What we do

Energy saving technology assessment

One service: an independent assessment of what an energy saving technology will do on your ship, on your routes, before you buy it.

The saving

Tailored to you

We calculate the fuel saved based on your ships and routes, factoring in the interactions between multiple technologies

The regulation

ETS, FuelEU, CII and EEXI

Regulatory impact is part of every assessment, calculated from the legislation itself for the routes the ship actually sails, year by year.

The money

Lifetime cash flow

Capital, fuel and carbon cost brought together as payback and net present value under your fuel and carbon price scenarios.

How it works

EVERY ASSESSMENT RUNS IN THE VIRTUAL MARITIME ENVIRONMENT

We model your ship from its geometry and powertrain, then sail it through decades of real weather on its own routes. First answers in weeks, re-runs in hours, and the model stays yours. The same platform can be pointed at a newbuild design or a whole fleet when needed.

What you get back

Cash flow with and without a technology

Illustrative VME output for a reference vessel. Bars show annual fuel and regulatory cost. Dotted lines show cumulative cash, with and without an energy saving technology fitted in 2027.

The saving has to repay the capital and beat a rising carbon bill. Every figure traces back to the vessel's own geometry, routes and weather.

Where we come from

Methods from Formula 1, EV development and Aerospace

In those industries fractions of a per cent decide outcomes, and simulation is trusted with them. We brought the same methods to shipping in tandem with chartered naval architects.
