Completion of GustoMSC designed first Japanese construction jack-up

Schiedam, Netherlands – February 8th, 2019 – Last week Penta-Ocean Construction Co., Ltd held the completion ceremony of its “CP-8001”, a GJ-3750C GustoMSC construction jack-up design. The delivery of “CP-8001” is an important milestone for the Japanese offshore wind development as this is the first and largest DP2 jack-up built in Japan for offshore wind and civil construction projects off the coast of Japan.

Penta-Ocean, one of the largest civil construction companies in Japan, ordered the GJ-3750C GustoMSC design at the Japan Marine United (JMU) shipyard in the fall of 2016. Earlier this year the company announced the completion of “CP-8001” followed by various sea- and jacking-trials in Japanese coastal waters. After its completion ceremony last week, the jack-up is now offcially ready for its first operations.

‘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’, says Jan-Mark Meeuwisse, Commercial Director, GustoMSC.

The GJ-3750C design

The GustoMSC GJ-3750C jack-up design is specifically tailored to Penta-Ocean’s requirements. It is able to instal large-scale marine structures such as 10 MW class wind turbines in water depths up to 30m with leg lengths of 66.7m, while the unit is designed for 86 m legs for 50m water depth. The accommodation offers living quarters for a maximum of 120 people as well as office rooms and recreational rooms. In addition, and not often seen in Japan, the GJ-3750C is equipped with a heli-deck for crew changes and emergency response. The “CP-8001” certifies Class NK DPS-B, a high precision automatic position system (DP2). With four thrusters the jack-up remains in a precise position even in severe conditions.

The GJ-3750C has been executed 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 40 cm per minute and has a pre-load capacity of 3,750 tons per leg. The entire project was built under Class NK and the unit is the largest DP jack-up registered by this class.
