Offshore geotechnics
Offshore renewable energy is providing an ever-increasing contribution towards our planet’s low carbon energy supply.
However, the offshore environment is harsh, and costs associated with construction and maintenance are high, which requires expertise and skill to ensure projects meet these challenges by providing efficient designs that perform in extreme conditions.
We have over 40 years of experience in offshore engineering, underpinned by our world class team of ground engineers.
Offshore wind
We provide design and advisory services across all aspects of offshore wind projects including project management and owners’ engineering services, supply chain studies, ports, infrastructure and fabrication, substations & electrical systems, foundation design, anchor design, moorings, floating platform design & optimisation, turbine control and integrated load analysis.
Our expertise in ground engineering services to the offshore renewables market includes site characterisation, seismic hazard and risk assessment, ground investigation design, management and interpretation, ground model development, survey planning and interpretation, site selection and cable thermal conductivity and landfall assessments. We deliver all stages of design from early feasibility through to detailed design of both fixed offshore foundations and anchors for floating wind. Our industry leading geotechnical numerical analysis team has extensive experience modelling the complex response of offshore foundations to optimise design and support our clients in managing installation risk.
For offshore wind farm operators, there’s relentless pressure on asset performance and operating costs. This pressure is increasing as the first installed wind farms reach the end of their usable life and need to capitalise on the opportunity for life extension.
Foundations are the only major component of offshore wind farms that cannot be replaced. It’s the foundation that determines the lifespan, through-life cost projections and viability of entire wind farms.
By measuring the loads in-service using our approach, the operational life of the windfarm can be extended from 25 to over 35 years. Our solution analyses data from an innovative system of sensors that continuously measure the load.
We’ve developed an innovative system using virtual sensors – accelerometers above the waterline that provide total asset insight with improved reliability, and remove the requirement for sub-waterline instrumentation. By combining monitoring and design stage analysis techniques, we cost-effectively deliver insight across the entire wind farm from a subset of monitored locations.
