New offshore wind turbine installation method
Netherlands based offshore self-elevating platform supplier Jack-Up Barge has pioneered a new cost-effective installation method that promises to revolutionise offshore wind turbine construction.
system, integrated to one of Jack-Up Barge’s platforms, enables the vessel to
operate between work sites offshore without recourse to a tug vessel. The
independence provided to the platform as a result ensures the delivery of an
extremely time-efficient installation process for offshore wind turbines. The
time saved during operations, combined with a reduced reliance on tugs, could
provide considerable cost efficiency relative to current, conventional
Managing director of Jack-Up Barge Ronald Schukking said: “This is a new system, pioneered by Jack-Up Barge, that aims to streamline operations for increased efficiency. Sea trials have been a complete success and we are very pleased with the performance of JB 118 and the new system. There is every indication that this will prove revolutionary for the platform based offshore installation process.”
The system can be mobilised to either JB 117 or JB 118 and, with only minimal adaptation, also to JB 114 or JB 115. This flexibility ensures wide availability of the system to clients at any time. The equipped platform will utilise the system exclusively for installation activities and will receive equipment supply from a purpose built feeder barge vessel currently in development. This continual, unbroken focus on installation work further develops the time-efficiency theme behind the development of the new system.
The system is
currently integrated on board JB 118. Installation took place recently at the
Keppel Verolme shipyard in the Port of Rotterdam. Each of the four retractable
thrusters was lifted on board with the platform’s own 1,000 tonne
Sea trials took place in the Dutch North Sea and, although this was the first time such a system had ever been trialed, passed smoothly. The new system has received the ABS classification DPS2 and is now ready for use in combination with one of Jack-Up Barge’s North Sea standard built platforms.
