Striving for Excellence in Sustainability and Customer Satisfaction

Collaborating for Innovative Engineering Solutions

Your partner in achieving a sustainable maritime industry for a greener future!

Innovative Naval Architecture

Sustainable designs and integration of innovative solutions towards a greener, sustainable maritime industry are at the heart of our services.

We provide solutions for new designs as well as extensive insights into the modification of existing maritime assets with a strong focus on decarbonising our client’s ongoing and future operations.

Powering the Future with Renewable Energy

We support our clients in accelerating the use of offshore renewable energy and in the development, design, construction, and maintenance of offshore renewable energy projects. Our solutions employ innovative approaches, technologies and have sustainable cost reductions at their core to enable a greener energy infrastructure reduced cost.

Green Marine Engineering

Through innovative design and cutting-edge technology, we strive to create vessels that are not only more sustainable but also safer for crew and passengers alike.


Our Areas of Expertise.

Naval architecture

Offshore engineering

Concept design

Offshore vessel supply

Technical office support

Research & Development



The project aims to determine the feasibility of installing a hydrogen-based propulsion and power system on the O.S. Energy GmbH vessel Søløven and develop a numerical tool that allows modelling of the vessels operation.

TransShip II

RV Prince Madog Hydrogen Retrofit (CMDC3)

This project aims to realise the largest retrofit to date for a hybrid, hydrogen-based propulsion system on a seagoing vessel, the RV Prince Madog, an industry leading research and survey vessel involved in ground-breaking maritime sciences and teaching of next generation scientist.

Project Zero

Zero Emission Research and offshore service vessel. (CMDC2)

Project ZERO is an initiative to develop a zero-emission research and offshore service vessel for the maritime industry. The project is a collaboration between several leading companies and research institutions, with the goal of reducing the carbon footprint of the maritime sector. 

Zero Emission Tri Foiler (CMDC3)

The vision for the project is to build a 12m demonstrator TriFoiler to prove that the concept is viable and can operate in a range of weather and sea conditions. The battery technology and control of the foils will also be demonstrated to check for fit for purpose operation as a fast ferry on the intended waterway.


In collaboration with R3-energise and Chartwell Marine we are investigating the feasibility of re-energising an existing CTV to full electric propulsion, thus delivering zero emission crew transfer services to a UK offshore wind Farm.

Maritime Hydrogen Highway


The Maritime Hydrogen Highway project is a ground-breaking two-year, £2.1 million development programme, looking at the scope to establish a national hydrogen highway network, integrating land, sea and port.
