DNV and also its companions on Thursday verified the conclusion of Phase 1 of a joint sector task (JIP) on Bottom Impact and also Partially Submerged Conditions, which has actually caused a brand-new structure for maximizing the setup procedure of overseas wind generators.
“New partners are encouraged to join Phase 2, which will focus on validating models and establishing common best-practice guidelines to the benefit of the entire industry,” DNV claimed.
“Offshore wind-turbine installation is currently done in very benign weather conditions to limit [Wind Turbine Installation Vessels’ ] WTIVs bottom impact of the jack-up legs with the seabed during the set-down phase. This severely restricts their operability and results in high day rates that make delays very costly for operators and charterers. Regions exposed to earthquake risk also require new operation philosophies, such as operating the crane with the WTIV in a semi-jacked condition,” DNV claimed.
“As the industry moves further into new territory with harsher weather, less forgiving seabed conditions, and seismic areas, there is an increased urgency to widen the weather window so projects can be completed more efficiently,” states JIP guiding board chairman Andries Hofman of GustoMSC BV.
DNV states that the lack of standards and also versions to totally comprehend bottom-impact pressures and also procedures in the semi-jacked problem caused the preliminary development of the JIP in November 2020.
The very early goal was to check out functional restrictions and also discover possible brand-new functional techniques.Reducing setup prices is essential to reducing the expense of overseas wind power in the middle of the drive to improve power safety. Pushing the borders without jeopardizing on security requires to be based on confirmed understanding, DNV claimed.
“The JIP work will be relevant for a long time to come, as bottom-fixed wind farms that require jack-up installation will remain the most cost-attractive way to diversify our energy mix. “ says JIP project manager Antonio Goncalves, Business Lead, Technical Advisory at DNV.
“The market is developing quicker than the rules, and the only way to make significant leaps is through sharing knowledge. Through better understanding of the forces at play and their consequences, we can increase performance and safety in worse sea conditions, enabling more efficient and timely turbine installation, which is a great opportunity for the whole industry.”
Phase 1 caused a mathematical design, established by DNV and also based upon the input of all JIP companions *, to properly anticipate bottom-impact pressures and also mimic semi-jacked problems. The JIP is currently open up to extra companions to sign up with the 2nd stage, with the goal of verifying the established versions with major dimensions and also developing usual best-practice standards.
DNV claimed that the task invites power firms, setup professionals, developers and also shipyards, crane producers or wind generator producers.
