Singapore-based Vallianz Holdings Limited has contracted Ulstein Design & Solutions BV for the development of their new, hybrid heavy transport vessel (HTV).

The new vessel, a customised Ulstein HX120 design, will be unique as it will feature dual-fuel engines and a battery energy storage system.

Designed for worldwide operations, the HTV will serve the growing transport demand in the offshore wind industry as well as for LNG modules and offshore structures.

Her dimensions are optimised to support Vallianz’s business case for not only transporting wind structures like monopiles, jackets, transition pieces and turbine blades, but also to carry out floatover operations of offshore

Featuring zero-emission capability, the DP-2 vessel will be the first of its kind, as it will be driven by a hybrid power system consisting of dual-fuel engines and a battery energy storage system.

The HTV’s electric battery system is to be provided by Canadian-based Shift Clean Energy, where Bureau Veritas will be responsible for the overall classification of the vessel.

Vallianz’s new HTV will feature the proven Ulstein X-BOW®, contributing to reduced energy consumption, as well as to more comfortable and safer operations when sailing through waves.
