Nodules rich in rare metals required for electrical batteries have been collected from the sea floor through a 4.5 km long riser designed and analysed by RiserTec. 5000 tonnes of nodules were collected from the sea floor and delivered to the production vessel during a 6 month trial of the system. RiserTec’s role was global riser analysis and fatigue performance assessment.

Nodules rich in rare metals required for electrical batteries have been collected from the sea floor through a 4.5 km long riser designed and analysed by RiserTec. 14 tonnes of nodules were collected from the sea floor and delivered to the production vessel during a 60-minute trial of the system. RiserTec’s role was global riser analysis and fatigue performance assessment.

An offshore wind turbine support structure conceived by RiserTec has entered the model testing phase. A 1:50 scale model of the Fixed TLP (FTLP) concept has been tested under operational and extreme wind and wave conditions. Test data is being processed for system evaluation and to support future optimisation before progressing to the next stage of the design process. The final design is planned to support a 15MW wind turbine in water depths up to and exceeding 100m.

RiserTec has been involved with the research & development of a new design of Offshore Wind Turbine support and mooring structure. The aim of the design is to provide a cost effective solution to the transport to site and support issues of Offshore Wind Turbines via the innovative use of existing technologies which are already industry recognized. Concept designs are being produced with the view of acquiring approval for further development by the relevant industry regulatory bodies.
