Ceep S92 heavy-duty waterproof connectors have been used in the Pelamis P-750, a novel, offshore, wave energy convertor that has just completed successful trials in the North Sea.
The Pelamis P-750 was developed by Ocean Power Delivery, an Edinburgh based company set up in January 1998 to develop the Pelamis WEC (wave energy convertor) concept for the offshore industry.
The first full-scale preproduction prototype is under construction and will be tested at the European Marine Energy Centre in Orkney later this year.
Pelamis is a semisubmerged, articulated structure composed of cylindrical sections linked by hinged joints.
The wave-induced motion of these joints is resisted by hydraulic rams that pump high-pressure oil through hydraulic motors that drive electrical generators.
Power from all the joints is fed down a single umbilical cable to a junction on the seabed.
Several devices can be connected together and linked to shore through a single seabed cable.
It is anticipated that future "wave farm" projects would consist of an arrangement of multiple interlinked machines connected to shore by a single subsea cable.
A typical 30MW installation would occupy a square kilometre of ocean and provide sufficient electricity for 20,000 homes.
Twenty of these farms could power a city such as Edinburgh.
Built in shell sizes of 10, 20, 30 and 40 and with over 40 contact arrangements, the S92 Ceep connectors chosen for this project are the most robust and competitively priced non-MIL SPEC, waterproof connectors on the market.
They are also ideal for the railroad, mining and light and sound industries, and are available in the UK from Aerco.
