Marine Services

Our oceans cover nearly three quarters of the earth’s surface and support an astounding diversity of life. As well as controlling the climate and carbon cycle, they are accountable for every second breathe we take. The RSK Marine Team work in close partnership with our clients to help ensure human developmental impacts are innovatively and sensitively managed. Our experienced team members are leading marine planners and regulators, ecologists and post consent operational support staff. The team’s strong environmental protection and ecosystem services approach are fundamental to the way we work.

Developers are now required to link corporate business objectives with sustainability drivers. In doing so, society can work towards a global net zero objective to help tackle climate change and biodiversity loss, which are intrinsically linked. Keen technical guidance and scientific expertise are vital in helping our clients meet these industry challenges in a diverse world.

With more than 25 years’ experience in delivering marine environmental services including environmental and social impact assessment (ESIA), RSK’s marine specialists offer a complete global consenting service for marine and coastal projects. Our innovative marine team has substantial experience in marine and coastal environmental research and consultancy working in diverse marine and coastal environments from intertidal zones to open ocean. These diverse environments include the North and South Atlantic oceans, the Arabian Gulf, the Indian Ocean and the Mediterranean, Caspian, Caribbean, North and Irish seas.

Our international maritime specialists provide world-renowned marine consultancy services and are waiting to support you throughout your project programme. We pride ourselves on our breadth of expertise and ability to work across the land–sea interface allowing us to respond quickly to help you make the best decisions, enabling innovative vison and growth.


RSK has significant experience of working with the offshore energy sector in developing cables and pipelines, oil and gas exploration/production and marine renewables. We provide feasibility and routing studies, scoping, ESIA and other planning and consent support, and post-consent and construction supervision services. We provide services for oil and gas majors including work in Lebanon, Papua New Guinea and Cyprus for Total E&P; in Mauritania for Shell; in Azerbaijan for BP; in Uganda and Tanzania for EACOP (Total E&P/CNOOC); and in Albania, Greece and Italy for the Trans-Adriatic Pipeline project. We also assist developers involved with offshore, nearshore, landfalls (intertidal) and connections to onshore grids, including National Grid, Scottish Power, SHETL, Shell Renewables, E.ON, Ørsted, RTE France, Warwick Energy and Centrica.

RSK provides an integrated project management service for marine renewable energy developers. We have project directors and project managers with recent experience of development consent orders for nationally significant infrastructure projects and Section 36 projects across the UK, with other regulatory requirements including Maritime and Coastguard Agency licences, foreshore licence applications in Ireland and other international permits. RSK can manage all aspects of development from conception to decommissioning, working with in-house teams and external subcontractors. Our project managers are skilled at delivering to programme and operating in a flexible way to suit client priorities. RSK has undertaken ESIAs for numerous offshore wind farm projects and their grid connections, including Rampion, East Anglia ONE, Triton Knoll wind farm and electrical system, Barrow, Walney, West of Duddon Sands and Cirrus Shell Flat Array. Through such projects, we have gained knowledge of the complexities of integrated working across the land–sea interface, combining the skills of associated teams and the nature of the information that is required to satisfy reporting and consenting requirements.

Coastal infrastructure

RSK provide ESIA and supporting services for developers involved with ports, dredging, reclamation, sea defences and bridges. These include residential, leisure, commercial and industrial developments involving channel deepening, reclamations, quay walls and jetties throughout the UK and internationally. We have experience in the Irish and North Sea, Arabian Gulf and the Red Sea and have supported such companies as the Port of Milford Haven Authority, Port of Barrow in Furness – Association of British Ports (ABP) Barrow, Ørsted, Port of Monaco and Société d’Exploitation des Ports SEPM (Monaco Government), Cansult Maunsell, ConocoPhillips, Parsons International, NMDC, Wilson Engineering and the Abu Dhabi Government.

Policy and planning

Through our breadth of work in the marine and coastal environment, we have extensive working knowledge of international marine and coastal policy and associated planning consents. We have notable experience of marine policy interpretation and strong relationships with marine regulators throughout the world, enabling us to navigate complex consenting requirements quickly. We are uniquely placed to support you in developing your project by offering end-to-end consenting services that use our knowledge and experience to identify applicable requirements and develop comprehensive project plans to aid the streamlined delivery of all consenting requirements and supporting documentation. Our project experience covers a broad range of industries, including oil and gas companies (Total E&P, BP, ExxonMobil), ports and harbours (Port of Monaco, Port of Barrow in Furness – ABP Barrow) and numerous developers (National Grid, Centrica, Parsons International and various worldwide governments). Our team’s experience and knowledge of consenting requirements coupled with our access to associate specialists means that we can support and respond quickly and objectively to unforeseen circumstances to help you succeed in your ventures.

The scope of our services and extent of our associated network means that few marine projects are beyond our capabilities. We work closely with our colleagues in international and UK ESIA teams to ensure a smooth, integrated and efficient consenting process.
