Original name SapuraKencana 3500. Originally designed to carry out multiple functions including oil piping processing, laying, installation and, primarily, heavy lifting. The vessel is capable of working in shallow water of up to 200 metres with a ten-point mooring system. Now working in offshore wind installation.

Developed by Ulstein Sea of Solutions, now Ulstein Design & Solutions B.V. The vessel is designed as self-propelled pipelay heavy lift vessel featuring 10-point mooring systems for operations in water depths up to 150 m, while for deep water operations it utilises its DP3 system. The operational profile of the Sapura 3500 is primarily targeted at heavy lift jobs.
The Stinger Handling System uses an A-frame, and was developed in parallel with the ship design. This integrated approach resulted in a very compact system, optimally integrated in the aft ship, with due consideration given to stinger section handling, maintenance and accessibility during operations. In addition to stinger handling, the A-frame can also be used for Deepwater Lowering purposes, using the wire of the Abandon & Recovery (A&R) system.
The design contract for the vessel was signed in December 2010, the design aiming for maximum efficiency and cost effectiveness. As such, the vessel features a centre single joint firing line to optimise pipe laying operations that are not hampered by vertical motions due to roll. Firing line and the single joint fabrication area is on a tween deck completely covered by the main deck, providing a clean and dry environment for the pipelay equipment and an unobstructed main deck for lifting operations.
Due to its large deck area, the vessel can be upgraded with a J-lay tower over the side.
2021: The vessel is currently operating as an installation vessel for offshore wind, and in February 2021, the vessel is reported to perform monopile installations on the Yunlin Offshore Wind Farm.
