The Samson was conceived in the early 1970s with the final design entering production in 1978. The hull is an all-welded aluminium construction. It usually carries a crew of three operating a 3.5T capstan winch that can also be utilised in a lifting configuration.
VB-10,000 performed its first lift on 9 October 2010, a 1,530-short-ton (1,390 t) topside and jacket which had toppled during a storm at Vermilion 285.
