Offshore wind

Specialist analysis and power system design expertise for a number of major offshore wind farm projects, ranging from 100MW to 7.2GW

We provide specialist analysis and power system design expertise for offshore wind farm projects of any size utilising VSC HVDC as well as long AC cables up to 180km of 220kV.

TNEI is involved in all aspects of the electrical system design of offshore wind farms, ranging from technical due diligence on next generation technology, specific technical studies, through to full system concept design and FEED.  We have a strong relationship with Petrofac, a service provider to the oil and gas and renewable industry, and as such, we are able to offer wider skillsets, including full substation platform and foundation engineering, operations and maintenance and offshore cable routing.

Our extensive experience in modelling the power characteristics of offshore generation technologies and the implications on grid capacity, stability and technology choice has been used to support technical evaluation of tender responses and technology due-diligence, in particular as part of the transitional OFTO process.  In the process of this work, we have developed software tools to analyse the tradeoffs between capital cost, operation and maintenance costs, losses and reliability / availability of different wind turbine array topologies. We have excellent relations with key electrical technology suppliers, including the critical VSC HVDC technologies.

We have been involved with several industry initiatives to evaluate the applicability of offshore HVDC technologies and optimal offshore network configuration and planning, from a technological, financial, operational and regulatory perspective.  We led the engineering work package of the ISLES project for the Republic of Ireland, Northern Ireland and Scottish Governments. This included the development of Life Cycle Cost models for offshore wind farms to provide justification for capital expenditure against operational and maintenance plans; including consideration of network reliability and availability, power losses and the cost of energy not delivered.
