Save money by auditing the energy consumption of your existing fleet. Quick energy savings with very acceptable payback times are really possible. They are reached by taking technical efficiency measures or replacing equipment with more efficient ones.

Once installed installations about your vessel consume energy. They affect your energy efficiency. This is especially important for your existing fleet since the energy consumers do not operate anymore in initial design conditions. The consume more fuel and money than necessary. Not many know that really tangible cost reductions are possible by just focussing on the technical installations of a ship.

Saving energy on the technical installations - main or auxiliaries - will be a major efficiency topic in the upcoming EEXI.

Let us dive into the energy consumption of your ships by auditing all energy consuming devices and practices. We assess every item for alternatives or energy saving practices. We provide you with specific options to reduce fuel consumption based on profiles of each individual ship.

Our report is SEEMP proof and direct suitable for your EEXI certification process.


In 2050 shipping must be carbon neutral. The present fuels need to be replaced by cleaner alternatives. But which?

The choice for a new marine fuel and technologies is difficult. Present fuels and machinery work simply perfect. It is proven technology with the perfect energy density. The choice for a different fuel is a difficult one.

Your ship and its operational profil decide which future fuel will be able to replace present fuels.

In order to ease the choice for the next fuel we developed the so-called Maritime Future Fuel Matrix. The fuel matrix assesses the feasibility of carbon neutral marine fuels. It gives insight if this new fuel supplies the energy you need.

The Future Fuel Matrix includes many of the proposed zero-emission marine fuels. It classes and weighs the fuels based on the success factors of marine fossil fuels. The weighing and classing is based on production, technology matureness, bunkering options, storing options, and environmental characteristics. Scientifically based.

We deliver a matrix and conclusions that are ship or company specific. It provides strategies about the options you can invest in safely.
