The ETI and Teignbridge Propellers International Limited (TPIL) are working together on a £3m project to develop a High Efficiency Propulsion System for ships

  •  High Efficiency Propulsion Systems (HEPS) are an effective way to improve fuel efficiency
  •  This two year project aims to develop a commercially-viable system that can be retrofitted to a variety of vessel types
  •  The HEPS technology will deliver a fuel efficiency benefit of greater than 8% on most vessels

Loughborough, 2 March 2017 – The Energy Technologies Institute (ETI) is partnering with Teignbridge Propellers International Limited (TPIL) to develop a High Efficiency Propulsion System for ships which aims to reduce fuel consumption by around 8%.

The two year project aims to develop a commercially-viable system that can be retrofitted to a variety of vessel types.

Based in Newton Abbot, Devon, Teignbridge is the largest propeller and stern gear producer of its kind in Europe.
Deborah Stubbs, the ETI’s High Efficiency Propulsion System Project Manager said:

“Unlike other forms of transport it is difficult to replace fossil fuels in marine vessels with low carbon alternatives so increasing fuel efficiency will become progressively more important if emissions and costs are to be reduced for the shipping industry.

“This project will develop a commercially viable product suitable for a wide range of vessels types and capable of being retrofitted to ensure it is attractive to ship owners and operators.

“It is one of a number of demonstration projects the ETI is running which, when used in combination, could reduce fuel consumption by up to 30% and cut the carbon emissions from shipping in a cost effective manner.”

David Duncan, the chairman of Teignbridge Propellers International Limited said:

“We are delighted to have been selected for this technology development and demonstration project, it fits very well with the company’s research and development strategy and plans. Teignbridge Propellers has an excellent engineering design team and a background of design development. The project will be helped by the use of the dedicated research test vessel presently under construction for Teignbridge Propellers. The selection by the ETI is a recognition and endorsement of the company’s abilities.”

The ETI has recently published an insight which analyses the UK shipping fleet, the potential opportunities for ship owners and operators and identifies the most promising technologies, including HEPS, that could reduce fuel consumption economically.

About the ETI

The ETI is a public-private partnership between global energy and engineering companies – BP, Caterpillar, EDF, Rolls-Royce and Shell – and the UK Government.

The role of the ETI is to act as a conduit between academia, industry and the government to accelerate the development of low carbon technologies. We bring together engineering projects that develop affordable, secure and sustainable technologies to help the UK address its long term emissions reductions targets as well as delivering nearer term benefits. We make targeted commercial investments in nine technology programmes across heat, power, transport and the infrastructure that links them.

About Teignbridge Propellers International Limited

Teignbridge Propellers International is a marine propeller and propulsion equipment designer and manufacturer. The company specialises in the design and manufacture of high performance custom designed propellers.

Teignbridge Propellers is ideally placed to carry out the research project because it has a complete propeller design and manufacturing facility including a foundry. It is one of the few propeller companies that actually design and manufacture propellers. The company has a propeller design that is unrivalled in fast boat trials. The research project will enable the company to develop a high efficiency ships propeller.

Research test vessel

This is a purpose designed and dedicated research vessel currently under construction. The twin hulled vessel will be used to trial and test a range of propellers and propulsion equipment. The vessel which is a floating laboratory is believed to be the first of its kind. It is capable of testing a range of propellers from slow speed with high bollard pull, to high speed in excess of 40 knots.
