Clements Marine has been appointed to supply propellers for the RNLI’s Trent class Lifeboats.

The first of the 20m aluminium windfarm support workboats Gardian, built by Seawork exhibitor Alicat Workboats, is now fully operational and the second vessel has just been delivered.

As suppliers of all stern gear and propellers to both vessels, fellow Seawork exhibitor Clements Marine worked with the builders throughout the project, including ensuring that once launched the vessel was working to its optimum performance.

Clements managing director Paul Williams said, ‘On this project we worked particularly closely with the engine manufacturers, in this case Caterpillar, to ensure that all the stern gear worked as efficiently as possible with their products.’

After the fit out at Richards Dry Dock & Engineering, sea trials were carried out at Holyhead and were very successful, with the vessel holding station against a marker for 20 minutes whilst there was a three foot tidal drop.

The Gardian’s Caterpillar C32 engines, rated 1,319hp at 1,800rpm, provide a maximum speed of 30 knots. The vessel is rated to MCA Category 2, 60 nautical miles offshore, and all the equipment supplied by Clements Marine was built to standard.

Clements Marine has also recently been appointed to supply propellers to the Royal National Lifeboat Institution (RNLI) for the charity’s Trent class Lifeboats.

The UK based propeller manufacturers have been appointed following extensive testing in association with the RNLI engineering team. The new Clements Marine propellers have seen reduced engine load and increased boat speed for the Trent Class. Last year, Clements Marine was appointed to supply to the RNLI’s Severn Class range of Lifeboats, as they underwent an extensive refit and repair programme.

Paul Williams said, ‘Our products are proven with the work we have done on the Severn Class and we are pleased to see that, following extensive testing, we are now supplying to the Trent class. Our products have to be robust as well as help make the vessels smooth and efficient.’
