Wind Energy – Decommissioning
Jumbo Offshore has completed the removal of two monopiles on the Offshore Wind Farm (OWF) Yunlin in Taiwan.
The Jumbo Offshore crew reliably carried out the work, whilst deploying its DP2 Heavy Lift Crane Vessel Fairplayer from Europe to support the onsite operations.
Jumbo Offshore was awarded the contract by Yunneng Wind Power Co. earlier this year for the removal of monopiles at the Yunlin OWF. The contract award represented an expansion of Jumbo Offshore’s existing scope, involving the transportation and installation (T&I) of the transition pieces.
Under the additional project scope, two monopiles, which previously suffered from a pile run during an earlier project phase, were to be removed. This involved underwater cutting of the monopiles into sections as well as recovery, transport and offloading of the sections.
The all-encompassing nature of the scope meant working with Jumbo’s dependable subcontractors. The Fairplayer was outfitted with an underwater abrasive cutting and lifting tool supplied by Claxton Engineering Services, as well as an ROV supplied by IKM subsea and survey equipment by Reach subsea.
With these, the Fairplayer could remove the monopiles successfully. The individual sections were lifted into the vessel’s cargo hold for transportation to a local Taiwanese port and offloading to the quayside.
