Floating Offshore Wind

Home » Wind Consultancy » Floating Offshore Wind Consultancy & Engineering

It is forecasted that 20% of new offshore wind could be floating by the mid-2030s, with installed capacity predicted to grow to 115 GW. Floating Offshore Wind has taken the new pioneer role in large-scale renewable technologies with first demonstration projects around the world. Alongside a host of advantages with floating technology, new challenges need to be overcome, and understanding of the technical implications is of paramount importance.

OWC’s team – including specialist integrated load analysis experts from INNOSEA (Part of OWC) – provides full-service floating offshore wind consultancy, including all necessary technical studies. In addition, we combine our offshore wind knowledge with that of parent company ABL Group’s vast floating structure experience acquired in the offshore oil & gas sector.

Together, we have a team that can realise your floating technology or project. Bringing real project experience derived from involvement in some of the world’s earliest and biggest floating projects dating back to 2009.

Market Challenges

Supply chain in demand, pushing up costs and availability of goods.

Variable water depth, seabed type and environmental conditions can make it difficult to select the correct floating foundation type.

Availability of expert personnel to support.

Lack of suitable port infrastructure to accommodate space needed for floating components.

On-site maintenance and repairs are complicated and costly.
