UK shipbuilder Wight Shipyard Co (WSC)ís newbuild hybrid vessel is claimed to set new industry standards in the patrol and pilot sectors helping operators, including port and river authorities, Police, MOD and Royal Navy meet strict new environmental standards.

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 is designed to provide operators with a reduction in both fuel costs and engine maintenance thanks to the ability to turn off the main engines for substantial periods of time.

“This ground-breaking project aims to set new standards in high speed, fuel economy and light weight vessels in the sector. Building greener vessels has been an integral focus for some time now so moving into hybrid options is the obvious next step forward,” said Peter Morton, CEO, WSC.

The WSC vessel has been designed by naval architect Chartwell Marine, and is the first in a new Chasewell range of pilot and patrol boat designs. Andy Page, naval architect and MD of Chartwell Marine, said the aim behind the design is to substantially improve air quality at major ports in the UK and further afield and help operators meet emissions reduction goals. The hybrid system architecture and an innovative low-drag hull form that minimises resistance throughout the speed range result from extensive research undertaken by Chartwell Marine under both diesel and electric propulsion. “Ultimately this hull form, optimised through extensive CFD testing, allows the operator to maximise time spent on electrical power, with substantial advantages when it comes to reducing total emissions,” he said. “With one of the first hybrids in build, Chartwell Marine and Wight Shipyard Co are leading in the development of alternative propulsion and putting a significant amount of R&D work into practice. WSC brings superior build quality and workmanship and a specific focus on weight reduction and fuel efficiency. This has a natural lead in to the growing hybrid requirement. Importantly, it also delivers all of its projects on time.”

Marine and Industrial Transmissions (MIT) and its manufacturing and technology partner Transfluid, are providing the hybrid system for the vessel.

The Transfluid HM560 marine hybrid unit delivers ratings of up to 164kW diesel power and 20kW electric power. Using rechargeable batteries and an integral battery management system, the unit actively manages power output and charge rate depending on the battery status and condition. The control system allows users to easily switch between operating modes. The intelligent software can integrate with other on-board systems for extended control and diagnostics.

The new vessel and its hybrid technology will be on show at the Seawork 2019 exhibition.
