Shaping the Future of Offshore Energy

Engineering Studies

We base our engineering studies on +20 years of experience from global offshore wind projects and our involvement in +50 offshore substation designs.

Our expertise spans from the foundational aspects of bottom-fixed wind installations to the dynamic realm of floating offshore wind, reflecting our adaptability and depth of knowledge.

We support you along the way in the DEVEX phase within concept; pre-FEED and FEED studies e.g. Electrical Transmission Architecture, Techno-Economic Modelling and Technology Assessment, so the best foundation of relevant knowledge can be secured before the final investment decision.

We excel in electrical power studies, ensuring seamless integration and optimisation of AC and DC systems, while our proficiency in HVAC technology positions us as leaders in efficient power transmission. Additionally, our pioneering work in Power-to-X technologies underscores our role in the transition to renewable energy sources, offering innovative solutions for energy conversion and storage

Bottom-Fixed Offshore Wind Projetcs

Engineering in bottom-fixed offshore wind projects encompasses all aspects of transmitting electricity from offshore turbines to the onshore grid. This involves designing and optimising electrical systems specific to fixed-bottom installations, such as integrating high-voltage subsea cables, offshore substations, and transformers. The process ensures minimal energy loss and addresses the unique challenges of securing infrastructure to the seabed. Additionally, it requires compliance with environmental and regulatory requirements and the implementation of robust safety measures to maintain system stability and reliability.

Electrical Systems and Integration:

Designing efficient electrical systems for offshore projects, focusing on cabling layout for effective power transmission, substation setup for robust offshore infrastructure, and grid integration for seamless offshore-to-onshore connectivity.

Auxiliary Systems and Infrastructure:

Ensuring safe access through the design of platforms and landings, communication systems to enable remote monitoring, and backup power solutions to ensure operational continuity.

Operation and Maintenance:

Conducting routine inspections to identify wear and tear, scheduling preventive actions for regular maintenance, and implementing condition monitoring to track turbine performance.

Safety and Risk Management:

Detecting potential safety threats through hazard identification, assessing likelihood and impact via risk evaluation, and implementing emergency response plans with safety protocols.

Foundation Engineering:

Evaluating seabed conditions through site assessment, designing structures to withstand environmental forces, and selecting materials to ensure durability and resistance
