JANUARY 8, 2019 — Laksevåg, Norway, headquartered Vestdavit has won orders to supply davits for three newbuild Esvagt Service Operations Vessels (SOVs) destined to support wind farm maintenance in challenging North Sea conditions.

Developed by Havyard Design & Solution and built by Havyard Ship Technology, the Esvagt trio will be delivered in 2020-2021. The construction project continues a run of eight Havyard designed vessels built for Esvagt, but the davit contract has brought Vestdavit particular satisfaction, after earlier projects went to competitors.

"These are repeat orders, demonstrating that Esvagt has been very happy with the quality and competitiveness of vessels delivered from the Leirvik yard," says Rolf Andreas Wigand, Managing Director, Vestdavit. "We are therefore especially delighted that Hayvard has switched its boat launching and recovery system preference for these latest high performance SOVs. This will also bring the number of Esvagt vessels equipped with davits from Vestdavit over a three year period to six."

Each of the SOVs will be equipped with one PAP-16000 workboat davit with emergency launch capabilities, one PLRH-5000 SOLAS davit, two L-3500 life raft davits and one telescopic painter boom, with all equipment to be delivered by 2020.

"More and more, wind farm development is taking place further from shore, increasing the need for specialized vessels to transport personnel to the turbine in demanding conditions," says Wigand. "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."

In the configurations delivered to Esvagt, both the PAP-16000 and PLRH-5000 davits will be able to perform in sea states up to 6.

With SWL of 16,000KG, 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. It 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 m/min and is equipped with shock absorbers and a constant tension system. It 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 is a fully SOLAS-approved davit designed for customers with high performance needs which Esvagt will use to launch and recover its own STB7 boat. The unit achieves lifting speeds as high as 60m/min and is equipped with shock absorbers, a constant tension system and hydraulic guiding arms.
