FIRST DP2 JACK-UP FOR OFFSHORE JAPAN
The first and largest DP2 jack-up built in Japan for offshore wind and civil construction projects off the coast of Japan has completed sea- and jacking-trials.
Ordered by Japanese civil construction company Penta-Ocean at the Japan Marine United (JMU) shipyard in 2016, the CP-8001 is a GJ-3750C GustoMSC construction jack-up design able to install large-scale marine structures such as 10MW class wind turbines in water depths up to 30m with leg lengths of 66.7m, while the unit is designed for 86m legs for 50m water depth.
Jan-Mark Meeuwisse, commercial director at GustoMSC, said: “‘The CP-8001’s unique features allow highly efficient operations in Japanese ocean side areas with harsh wave and weather conditions, while not giving in on the welfare of the crew.
“The proven technology make it most suitable for various installation works from a safe and stable self-elevating platform. The enactment of relevant Japanese regulations will undoubtedly provide further potential for offshore wind farm projects.”
Continuous jacking system
Specifically tailored to Penta-Ocean’s requirements, CP-8001 has been built with the GustoMSC 3750C continuous jacking system, a derivative from the larger and proven systems used in jack-ups built to NG-9000C and NG-5500C GustoMSC design.
This jacking system is capable to lift the platform in a continuous motion with 40cm per minute and has a pre-load capacity of 3,750t per leg. With four thrusters the jack-up is designed to remain in a precise position even in severe conditions.
Built under Class NK, CP-8001 is the largest DP jack-up registered by this class.
