We are leading the evolution of the maritime sector towards an efficient, sustainable and low-carbon future. Independent and impartial, we offer a level of industry expertise and technical capability across the full product life cycle for multiple international markets that few others are able to match.

Our deep technical and domain knowledge, complemented by expansive expertise in policy, economics, regulation, environmental and safety services, life cycle assessment, strategy and planning uniquely positions us to support our clients.

Our technical expertise and domain knowledge are unique within the global maritime sector. Organisations engaged in environmental policymaking  appreciate the depth and breadth of our maritime expertise.

Our forward-looking understanding of future policy, and development of scenarios shapes our private clients’ future strategic plans around investment decisions, costs of ownership and environmental impact. 

Our consultants have decades of experienced conducting multi-sector product life cycle assessment studies compliant to ISO 14040.

We have the longest-established and one of the largest specialist air quality team in the world and a world-leading chemical emergency response team.

We work across the whole maritime value chain. We provide high quality evidence-based research and advice for policy decisions. We analyse the techno-economic, social and environmental impacts of market drivers and disruptive technologies.

We innovate, implement and test: using the latest scientific understanding to shape our design and development of alternative power and propulsion systems with conventional and alternative fuels and energy sources.

Trusted by local, regional and national governments, environmental non-governmental organisations and international industry associations, we work extensively for the European Commission, (including supporting DG Climate Action), the International Maritime Organization (IMO) and IMO Member states, and have developed a zero emission blueprint for shipping with the International Chamber of Shipping.

Our private clients include some of the world’s largest port/harbour/marina operators, naval architects, shipbuilders, ship owners, operators and suppliers, marine engine original equipment manufacturers (OEMs), propulsion and power system tier one suppliers plus oil and gas companies.

We deliver turnkey engineering services around clean sustainable propulsion and energy systems: battery and fuel cells, emotors and clean internal combustion engines using conventional and alternative zero carbon fuels including hydrogen and ammonia. Our capability ranges from feasibility to concept, detailed design, analysis and simulations, controls development, energy optimisation, performance, emission improvement and issue resolution.
