The second will display real-time wind, wave, temperature and current information via satellite from a buoy in the North Sea.

XJF Plastics will be displaying an Eason Marine Class 2 Lightweight buoy at Seawork, which is now established as a viable alternative to traditional steel buoys. Following extensive trials, Trinity House has recently contracted XJF Plastics for an initial supply of 25 of the model for use at inshore sheltered water locations.

A Trinity House statement read, ‘Over a period of 12 months Trnity House carried out trials that were exhaustive in assessing performance, durability and function of a number of lightweight products from different manufacturers. Trinity House has recognised the many advantages that lightweight buoys present and found that XJF Plastic’s product best met its specific requirements on this occasion.’

Rotationally moulded polyethylene buoys require very little maintenance. They do not rust, do not need painting and can be easily jet cleaned and quickly returned to position. Since they are just a third of the weight of steel buoys they can be serviced by smaller vessels or even serviced at sea, doing away with the need for a buoy yard for the expensive sandblasting and repainting of steel alternatives. A further benefit of lightweight buoys is that smaller chain sizes can be used and chain wear is greatly reduced, lowering costs and minimizing the risk of the buoys getting washed up on beaches or out to sea.

‘Trials have shown that compared to steel buoys, Eason Marine lightweight buoys can save port authorities and harbours up to £4,500 each over five years in servicing costs, said Peter Eason. ‘Further savings of up to £90,000 over five years could be achieved from a reduction in service boat and crew demands.’

XJF Plastics has developed a range of buoys and navigational aids for use in some of the busiest sealanes and harbours in the world. The 3m Class 2 buoy allows the capability to include solar panels, temperature, wave and current monitoring equipment. All buoys are designed with safety in mind. Non-slip surfaces can be applied to the floating section and safety handrails can be attached to the daymark where appropriate.
