Barrus has supplied engines for the UK’s first hybrid pilot boat.

Leader has been built by Goodchild Marine Services for the Port of London Authority as part of the port’s commitment to adopting new, green technology.

The parallel hybrid pilot boat combines both diesel and electric power and has been designed to be completely emission free whilst operating in electric mode.

Marine and Industrial Transmissions (MIT) and its manufacturing and technology partners, Transfluid, have partnered the project by providing the plug-in hybrid system, alongside Barrus that supplied the Yanmar inboard diesel engines.

The twin 6LY400 common rail engines were modified by the Barrus special products division to suit the craft. They operate on a 24V system with electromagnetc water pumps driven from the engine.


The operating system on both engines was converted from 12V to 24V twin pole, isolated return and a Jobsco electromagnetic water pump was fitted to both engines on custom-built support brackets designed in-house.

Both engines are controlled by Yanmar’s VC10 flyby wire system with the integration of Transfluid’s control head.

The control head has been adapted to operate both the engines and hybrid system from the touch of a button.

Leader is expected to reach up to 15 knots under hybrid power with the Yanmar engines achieving 19 knots at 3300rpm during sea trials.

The PLA recently published its Air Quality Strategy for the Tidal Thames, aiming to reduce river-based air pollution.
