The Guo Hai Min Xing and the Guo Hai Min Sheng completed sea trials and were delivered on 8 May 2020. A further two vessels are scheduled and all four will be operated by China Oilfield Services Ltd with whom SWS has a long-term charter.

The 89m Ulstein PX121 is a flexible platform supply vessel design featuring the X-BOW hull line design for smoother motions in head seas. In total, 30 vessels of this design have so far been contracted.

A platform supply vessel of this design has a competitive combination of fuel-efficiency and cargo capacities/deadweight. This translates to a performance level that is usually expected from larger PSVs, but at a medium-sized PSV cost
