Shearwater Topaz was the second in a series of Diving Support Vessels (DSVs) built at De Hoop Shipyard in Lobith, The Netherlands. The vessel was named and launched on 1st May 1982 and sold to Lyle Shipping for $26 million USD. The DSV was in effect, built around a saturation diving system which is the core component part of the vessel enabling divers to live at depth. The vessel was developed from concept to design and as can be seen from the pictures below. These state of the art multi-purpose offshore support and diving vessels were very successful and took divers into a new realm of safety. This vessel had a split level 18 man saturation diving system onboard, dive control room and gas room for breathing support. The Shearwater Sapphire is now called the Seamec II, operated by Seamec Limited under Indian Flag. She is an offshore support vessel and is still going some 34 years on from her delivery date in May 1982.
