Exploring the feasibility of placing a wind turbine on top of an FPSO

Changing the way of power production on a Floating, Production, Storage, and Offloading (FPSO)<br/>system by using renewable power can contribute to reducing an FPSO’s carbon footprint while operating. Bluewater Energy Services is interested in the use of a wind turbine placed on top of an<br/>FPSO, to power the FPSO’s internal electricity grid....

Motion prediction of a Semi-Submersible Crane Vessel at inconvenient draft: Identifying the cause of the discrepancies on an experimental basis

During specific operations, offshore marine contractor Heerema Marine Contractors reduces the draft of their Semi-Submersible Crane Vessel (SSCV) such that the floaters are submerged in close proximity to the free surface. This draft is also known as inconvenient draft. At this draft the motions of the vessel do not fully comply anymore with the...

Mooring system design, related to Pioneering Spirit: Improvement of a mooring system to secure a barge alongside Pioneering Spirit in offshore conditions, including an evaluation of the dynamic loads

Continuous development in the wind turbine industry leads to increasing size of wind turbines. Allseas investigates the possibility to enter the offshore wind turbine installation industry with Pioneering Spirit.<br/>For Allseas’ preliminary wind turbine installation design, wind turbines are assembled offshore, requiring wind turbine components...
