Denmark’s Esvagt will install davits from Vestdavit on three service operations vessels (SOVs) for deployment at offshore wind farms in the North Sea.
Each of the SOVs will be equipped with one PAP-16000 Workboat davit with emergency launch capabilities, one PLRH-5000 International Convention for the Safety of Life at Sea davit, two L-3500 Life raft davits and one telescopic painter boom.
The equipment for the SOVs, which will be used to support maintenance activities, will be delivered by 2020.
Both the PAP-16000 and PLRH-5000 davits will be able to perform in sea states up to six.
Developed by Havyard Design & Solution and built by Havyard Ship Technology, the Esvagt trio will be delivered in 2020-2021.
Vestadavit managing director Rolf Andreas Wigand said: “These are repeat orders, demonstrating that Esvagt has been very happy with the quality and competitiveness of vessels delivered from the Leirvik yard.”
“We are therefore especially delighted that Hayvard has switched its boat launching and recovery system preference for these latest high performance SOVs.
The deal will also bring the number of Esvagt vessels equipped with davits from Vestdavit over a three-year period to six, according to Wigand.
Wigand said: “More and more, windfarm development is taking place further from shore, increasing the need for specialised vessels to transport personnel to the turbine in demanding conditions.
“Boat launch and recovery requires special attention to match expectations for the SOV and ensure that crews are comfortable and safe when sea states are high.”
The PAP-16000 is Vestdavit’s largest single point davit and uses a docking head to fix the boat into position during the lifting and lowering process.
The small crane is designed to handle Esvagt`s large STB12 workboat fully equipped.
To do this in challenging seas the davit will offer lifting speeds of 45 metres a minute and is equipped with shock absorbers and a constant tension system.
The system will also be supported by a long-outreach telescopic painter boom with winch to provide adjustable tension on the painter line.
The PLRH-5000 davit achieves lifting speeds as high as 60 metres a minute and is equipped with shock absorbers, a constant tension system and hydraulic guiding arms.
