Vallianz in partnership to develop hybrid heavy transport vessel for offshore wind farms

Share

Vallianz Holdings Limited has joined forces with Ulstein Design & Solutions B.V., Shift Clean Energy and Bureau Veritas to collaborate on the design and construction of a heavy transport vessel (HTV) that will be the first of its kind in the global offshore wind industry.

Designed for worldwide operations, the HTV will be deployed for the transportation of structures such as monopiles, jackets, transition pieces and turbine blades to support offshore wind farm projects, as well as heavy structure modules for LNG and carry out floatover operations of offshore structures.

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 alternative dual fuelled engines and a fully-classed battery energy storage system. In addition, the HTV features the proven ULSTEIN X-BOW®, which contributes to reduced energy consumption and provides more comfortable and safer operations when sailing through waves.

With an overall length of 173.6 meters, the customised ULSTEIN HX120 design will have a free deck length of 145 meters. With her large deck area of more than 6,000 square meters and deck strength of 25 tonnes per square meter, the new HTV can carry cargoes of up to 32,000 metric tonnes. This includes very large structures and modules, such as monopiles, transition pieces and jacket foundations.

The design of the HTV is developed by the Dutch design office of Ulstein Group, which is headquartered in Norway. The HTV’s electric battery system is to be provided by Canadian-based Shift, while the vessel will be classed by Bureau Veritas.
Construction is expected to take up to 26 months, with planned completion by the end of 2024.

To mark the collaboration, representatives from Vallianz, Ulstein, Shift and Bureau Veritas attended a signing ceremony held at Ulstein’s office in Rotterdam, in the Netherlands.

Mr Osman Ibrahim, Chairman of Vallianz, said: “This collaboration is a key development in the Group’s strategy to build a stronger presence in the global offshore wind farm industry. It follows closely on the heels of another strategic project that we embarked on for the construction of a next generation Service Operation Vessel (SOV) to support the operations and maintenance of offshore wind farms.

“In view of the anticipated increase in the size of monopiles and other components for offshore wind farms over the coming years, we believe there will be a growing demand for newer generation vessels like our HTV which can help to facilitate faster installation speed, better project economics and reduction of carbon footprint. The addition of this HTV will also complement and expand on the Group’s existing ‘Holmen’ fleet of heavy lift transport vessels.”

“Since 2010, offshore wind has been a focus market for Ulstein”, said Ms Cathrine Marti, CEO of Ulstein Group. “With our track record in SOVs, heavy lift vessels and rock installation vessels, we have built up a strong position as ship designer supporting offshore wind installation and maintenance. This agreement with Vallianz is an important step for us, as it is in line with our strategy to expand into vessels supporting offshore wind logistics.”

Mr Francis Tang, Commercial Director of Bureau Veritas Marine Singapore, said: “Bureau Veritas is honoured to participate in this ground-breaking project and to support our close customer Vallianz and partners to further push the boundaries in maritime and offshore decarbonisation by tapping into our deep expertise in alternative fuels and hybrid technologies.”

Mr Brent Perry, CEO of Shift Clean Energy, said: “Energy Storage is mature and ready to take on the challenge of decarbonisation today. Collaboration with all parties is the key that will support Energy Storage System (ESS) in delivering on performance, cost and environmental benefits.”
