Singapore based companies Vallianz Holdings Limited and SeaTech Solutions International Pte Ltd on Friday (5 February) entered into a binding two-year Memorandum of Understanding for the development of a next generation environmentally friendly harbour tugboat.
The all-electric tug (e-tug), based on SeaTech’s EVT-60 design, is powered by clean energy with an aim of zero carbon emissions.
Measuring an overall length of 26 meters and beam of 12.8 meters, the e-tug will be equipped with azimuth propulsion and have a bollard pull of 60 tonnes with service speed of 12 knots. Its high-capacity electric battery modules will also pack enough power for its operational profile.
Upon completing development of SeaTech’s EVT-60 design for the e-tug, Vallianz intends to utilise the Group’s shipyard, Vallianz PT USP (a 99% owned subsidiary of the Group), to begin preparation works for potential clients and vessel owners who are interested in constructing an e-tug.
The design of the e-tug will be carried out in accordance with the American Bureau of Shipping (ABS) “Guide for Use of Lithium Batteries in the Marine and Offshore Industries” and the ABS “Guide for Hybrid Electric Power Systems for Marine and Offshore Applications”.
SeaTech has developed the EVT-60 design with a brand-new battery powered concept. The power delivery of the e-tug’s battery can be optimized according to the vessel’s real-time power demand. This will result in a more flexible and efficient operation as the e-tug will have the ability to provide a range of bollard pull to meet different operational requirements.
“Technology for electric vessels is available, and the real challenge is to develop a cost-effective total logistics solution,” said Govinder Chopra, Director of SeaTech.
“We target a CAPEX increase of only 20% with lower life cycle costs for this electric tug. The electric tug lends itself to digitalisation and future autonomous operations. We see this as the future of harbour Tugs and we are delighted to bring this Technology to SEAsia.”
Darren Yeo, Executive Vice Chairman of Vallianz, notes the strategic partnership marks Vallianz’s first step into the development of electric vessels.
“With the rise in demand for decarbonisation, coupled with the evolving digitised efficiency management systems for vessels, we foresee increasing requirements for electric vessels in the near future,” he explained.
“We believe the partnership with SeaTech will showcase Vallianz’s ability to diversify its strengths and constantly innovate as we work towards achieving long-term growth and sustainability.”
Gareth Burton, Vice President, Technology of ABS, was pleased with the development.
“Hybrid electric power systems offer the opportunity to improve safety, reliability, operational efficiency and reduce the fuel consumption, environmental footprint and equipment maintenance when compared to traditional power systems,” said Burton.
“ABS has long supported shipowners looking to utilise this technology and is an industry leader in developing guidance that advances safer integration of hybrid power systems into marine and offshore assets.”
