Davit supplier Vestdavit has completed an extensive retrofit project carried out by Bay Ship and Yacht California, onboard the US Army Corp of Engineers’ trailing suction hopper dredger Yaquina.
The davit selected for the retrofit, a compact F-10000 work boat davit, is a dual point davit capable of launching a 8-m- world boat on a daily basis from a 60 m dredger, built in the 1980s.
In addition to its space-saving footprint, the 10,000 kg load-bearing F-10000 davit also has a dynamic shock absorber system, a constant tension winch and anti-sway guide arms.

The complete refurbishment of Yaquina involved the overhaul of main propulsion and auxiliary plant, dredge equipment renewal, hull cleaning and coating, in a project that included two months in drydock.

Based in Portland, Oregon, the 2,943 dwt dredger’s mission is to maintain federal navigation channels in the Pacific Northwest. According to Army Corp of Engineers figures, 2.6-3.4 million m3 of material is dredged from the mouth of the Columbia River each year.

Magnus Oding, general manager Vestdavit USA, said, “Our davit systems are already widely used by the US Navy, the US Coast Guard, the National Oceanic and Atmospheric Administration, and in the offshore oil industry among others.”
