A wind turbine installation vessel (WTIV) is a vessel specifically designed for the installation of offshore wind turbines. There were 16 vessels in 2020.[1]
Similar to a jackup rig it is self-elevating. To enable quick relocation in the wind farm it is self-propelled. It also has a slender ship shaped hull[2] to achieve a quick turnaround time with the vessel carrying several foundations or wind turbines each time.[3] Azimuth thrusters are used to position the vessel during jack-up operations.[3] Some may carry 5 modern wind turbines, and lift 700 tonnes 125 meters above deck.[4][5] Some WTIV use biodegradable hydraulic fluids to minimize ecosystem impact during leaks.[6] A vessel can cost[7] $335 million, or $220,000 per day.[8] A 3-year leasing may cost €90 million.[9] The fleet of 16 vessels are scheduled to expand to 23 vessels by 2023, of which 7 can handle the largest turbines.[8][1]
Projects include lift capacity of 1,600 tonnes, and a 155 meter crane height.[10] In Korea, some vessels are approved for liquefied natural gas.[11] In China, lack of suitable vessels are slowing the construction of offshore wind farms.[12] Construction of the four-legged US Jones Act-compliant Charybdis started at Keppel in Texas in late 2020, at a cost of a half billion dollars,[13] scheduled for the 700 MW Revolution Wind in 2023 and the 924 MW Sunrise Wind in 2024.[14] Such vessels require 500-800 MW of installation per year for 5 years to be economical.[15]
A supplement to crane-equipped WTIVs can be crane-less feeder vessels with motion compensation.[16]
