and apply that knowledge and technology to the development high efficiency ships propeller.
The ETI is a £400m industry and government funded research institute into low carbon energy system planning and technology development to address UK energy and climate change targets.
Deborah Stubbs, project manager for the ETI’s High Efficiency Propulsion System Project 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 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.”
In January 2017, the ETI published an insight paper which analysed the UK shipping fleet and the potential opportunities for ship owners and operators to reduce their CO2 emissions. The paper
identified the most promising technologies to pursue following comprehensive studies on fuel efficiency savings options.
During the initial stages of the HEPS project, Teignbridge undertook an extensive review of existing propulsion technology as well as technology under development. This work included the investigation of manufacturer efficiency claims as well as analysis of competition to the proposed Teignbridge technology
In order to define a successful marketing plan for the HEPS technology, Teignbridge has carried out an extensive review of the marine propeller market to identify the target market sectors which represent low barriers to entry and those which present the greatest long-term opportunity. Based on the current structure of the marine propeller market, three market segments of retrofit, new build and alternative & niche markets will be targeted.
In the retrofit market, Teignbridge has identified 17,000 medium to large size vessels which could benefit from the new HEPS technology. The European market was found to be the priority market region, with the Greek market showing the highest potential, followed by the UK, Germany and the Netherlands. The medium term expected impact of the HEPS technology on UK fleet carbon dioxide emission reduction is expected to be in the order 1.5%.
Despite a challenging global market, orders for new ships continue to be placed on an almost daily basis and customers are demanding increasing fuel efficiency and reduced emissions from these new ships. The number of annual new build orders is currently estimated at 150 for medium to large vessels – Teignbridge has identified the current market slow down as an opportunity to access new markets through innovation.
There are approximately 150 large shipyards in Europe. Around 40 of them are active in the global market for large seagoing commercial vessels, with a market share of around 6% in terms of tonnage and 35% for marine equipment. Europe along with regions such as Vietnam, Philippines, Indonesia, Canada, USA, Russia, South America, Australia, and India will be priority regions for selling the Teignbridge HEPS technology in the new build market.
In the alternative and niche markets, Teignbridge will be targeting smaller commercial vessels. Although this sector only accounts for 1% of world tonnage, it represents 37% of vessels numbers in the world fleet. The alternative and niche market includes the thruster market, work boats, inland waterway vessels, deep sea fishing and military vessels. Teignbridge already has a strong market presence in these sectors and is known to most shipbuilding yards and owners. Teignbridge will target a market share of 7.5% in five years.
Teignbridge is currently building a research test vessel which will be used as part of the ETI HEPS project to test and evaluate prototypes of the proposed technology. The purpose-built catamaran research vessel is designed with a test cell comprising of a moon pool and instrumented, retractable podded- propulsor with at- sea propeller change capability. The vessel will operate as a floating laboratory and is believed to be the first of its kind. It will be capable of testing a range of propellers and propulsion equipment from slow speed with high bollard pull, to high speed operation up to 40 knots.
