Singapore-based Ultra Deep Solutions has signed a letter of intent to build a SALT 310 well intervention vessel at China Merchants Heavy Industry (CMHI) yard in Shenzhen.
Ultra Deep Solutions says the vessel will be capable of well intervention, flex lay and rigid pipe lay in 3000m water depth.
It will have a "first-of-a-kind," 3-in-1 tower designed by Huisman in the Netherlands. The crane will also be Huisman built, at 600-1000-tonne, and able to work to 3000m water depth.
The vessel will also have a 650 msw hydrogen saturation system, two work class ROVs built into hangars and two in-built hydrogen refineries.
UDS specializes in the design, construction and operations of ultra-deep diving heavy construction vessels to the offshore industry.
