UK shipbuilder Wight Shipyard Company’s newbuild hybrid vessel promises to set new industry standards in the patrol and pilot sectors.

The port environment is becoming an even more strict environment to work in when it comes to environmental regulation and clean air requirements. Port authorities, harbour and river patrols now require a vessel that can operate and switch easily between variable speeds; operating at low speed when environmental consideration is needed in heavily polluted areas and high speed when required.

WSC’s new hybrid vessel also provides operators with a reduction in both fuel costs and engine maintenance because there is the ability to turn off the main engines for substantial periods of time.

The WSC vessel has been designed by naval architect Chartwell Marine, and is the first in the new Chasewell range of pilot and patrol boats, first unveiled at Seawork 2018.

It has been designed and built in collaboration with Andy Page, naval architect and managing director of Chartwell Marine.

Mr Page said the vessel has a unique hybrid system architecture and an innovative new hull form that minimises drag and resistance throughout the speed range. He said that the hull form results from extensive research undertaken by the team at Chartwell Marine into low speed resistance enabling efficient performance under both diesel and electrical propulsion.

“Ultimately this hull form, optimised through extensive computational flow dynamics (CFD) testing, allows the operator to maximise time spent on electrical power, with substantial advantages when it comes to reducing total emissions,” he said.

Andy Page will be addressing the audience at Seawork Hybrid Conference this year.

Marine and Industrial Transmissions Limited (MIT) and its manufacturing and technology partner Transfluid, are providing the hybrid system for the vessel. MIT’s tried and tested system was selected to form part of the Chasewell power train, plus an integrator that had the technical expertise to do the job.

The Transfluid HM560 marine hybrid unit used in the drive configuration delivers ratings of up to 164kW diesel power and 20kW electric power.

The new vessel will be on show at Seawork this year Wight Shipyard Co berth VB02 and stand PG146 and the hybrid technology will be on display on the MIT stand PO5.
