Seven Havila claims world record for a DSVProjects and Operations // January 31, 2012
Seven Havila had eight divers on the seabed during the test.
The dive support vessel (DSV) Seven Havila recently achieved a world first for the number of divers working on the seabed from a single vessel.
Seven Havila is owned by Subsea 7 and Havila Shipping, and was designed and built by Herøy-based Havyard Group. The vessel won OSJ’ magazine's Support Vessel of the Year award in 2011.
Gael Cailleaux, vice president for offshore resources at Subsea 7 confirmed that eight divers were in action from the vessel at the same time. “To our knowledge, there have never been so many divers on the seabed from a single DSV simultaneously. We wanted to test having eight divers on the seabed at the same time, with both diving bells in action together. While one diver stayed inside each diving bell, three divers from each diving bell worked outside.” The diving test took place near Stavanger, Norway, in a water depth of 30m.
The dive system on the vessel, which was supplied by the German company Dræger, includes a 10-chamber 24-man saturation suite with double bell handling system able to work down to 400m and in up to 6m Hs.
