Duo developing all-electric harbour tugs

SeaTech Solutions and Vallianz are teaming up to develop ‘next generation’ all-electric harbour tugs based on SeaTech’s EVT-60 design.

The companies have entered into a binding Memorandum of Understanding (MOU) which will be valid for two years unless mutually extended in writing by both parties.

According to Vallianz, the e-tug will support vessel owners to comply with the International Martiime Organization’s (IMO) 2030 and 2050 emission reduction targets.

The 26-metre long e-tug will be equipped with azimuth propulsion and have a bollard pull of 60 tonnes with service speed of 12 knots.

Upon completing development of SeaTech’s EVT-60 design for the e-tug, Vallianz intends to use the group’s shipyard, Vallianz PT USP (a 99% owned subsidiary of the group), to begin preparation works for potential clients 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 says it has developed the EVT-60 design with ‘a brand-new battery powered concept’. According to the company, the power delivery of the e-tug’s battery can be optimised according to the vessel’s real-time power demand – which 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.

Govinder Chopra, Director of SeaTech, commented: ‘Technology for electric vessels is available, and the real challenge is to develop a cost-effective total logistics solution. 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.’

Darren Yeo, Executive Vice Chairman of Vallianz, added: ‘This strategic partnership marks Vallianz’s first step into the development of electric vessels, which demonstrates our aim to be among the leaders recognised for active reduction of carbon emissions in the marine industry. 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.’
