Ulstein has officially introduced the HX103 and HX104 designs, DP3 vessels at the OTC 2015 conference in Houston.
A dedicated feature on the DP3 designed vessels is the heavy-lift capability with large outreach combined with a large open deck space and accommodation for 350 and 500 people on board.
Ulstein says that the fully SPS compliant designs also mark the entry of the ULSTEIN X-BOW in this segment of the construction market.
According to the press release, Ulstein has paid significant attention to combine good DP capabilities with relatively small installed power and smart DP lay-out, reducing the vessel’s overall environmental footprint.
Optimised for DP2 capability, the HX103 design includes a main crane of 1,000 tonnes at 26m outreach revolving and 320 tonnes at 68m, as well as a deck crane of 50 tonnes at 24m outreach. Its “big brother”, the ULSTEIN HX104 design, has a heavy-lift capability of 2,000 tonnes at 30 m radius and 685 tonnes at 74 m outreach.
