***Solitaire*** is a large deep-sea [pipe laying ship](/source/Pipe-laying_ship). It was at the time of conversion the world's largest [pipe-laying ship](/source/Pipe-laying_ship) at 300 metres (984 ft) long (excluding pipe-laying apparatus)[3] and 96,000 tonnes (94,000 long tons; 106,000 short tons).[4] When fully operational she has a crew of 420,[4] a pipe carrying capacity of 22,000 tonnes and a pipe lay speed of more than 9 kilometres (5.6 mi) a day.[5] The ship is owned by the [Allseas Group](/source/Allseas), a Dutch pipelaying and marine construction firm with their headquarters in [Switzerland](/source/Switzerland).[6]

## History

The ship was initially built in 1972 as a [bulk carrier](/source/Bulk_carrier) and launched as *Trentwood* by [Mitsubishi Heavy Industries](/source/Mitsubishi_Heavy_Industries) at their shipyard in [Hiroshima](/source/Hiroshima), Japan.[2]

In 1992, [Allseas](/source/Allseas) acquired *Trentwood* for conversion into a pipelaying vessel. Allseas awarded the conversion contract to [Sembawang Shipyards](https://en.wikipedia.org/w/index.php?title=Sembawang_Shipyards&action=edit&redlink=1) in Singapore on a lump sum basis; however, the contract was terminated in 1995. The ship was subsequently converted at the Swan Hunter yard on [Tyneside](/source/Tyneside), United Kingdom.[7] *Solitaire* laid her first pipe on Statoil's Europipe project in 1999.[8]

Allseas and [Sembcorp](/source/Sembcorp) reached a settlement for the *Solitaire* arbitration in 2006.[9]

In 2006, while working on the Atwater Valley and Independence Trail projects in the [Gulf of Mexico](/source/Gulf_of_Mexico), *Solitaire* set new depth records, laying 10-inch pipeline in a water depth of 2,775 metres (9,104 ft) and 24-inch pipeline in a water depth of 2,550 metres (8,370 ft).[10]

Among other ships, *Solitaire* laid the [Nord Stream 2](/source/Nord_Stream_2) gas pipeline in the [Baltic Sea](/source/Baltic_Sea) in 2019—2020.[11]
