Jee completes tidal cable protection structure

Scottish Tidal Project has moved step closer to finalization with the completion of the tidal cable management and protection structure.

Jee’s protection system, the ‘U-tube’, features a pipe fixed to a J-tube which is secured to the turbine foundations at each end of the pipe.

The cable is then pulled vertically into one of the J-tubes and through the pipe using a pre-installed messenger and winch line.

Once the cable is pulled in, connections are made to the turbine nacelles using wet-mate connections.

According to Jee, the U-tube demonstration trial will take place off Orkney during September, 2015.

It will be the largest structure to ever be deployed in a high energy tidal environment which utilises a low cost installation vessel arrangement, comprising of a gantry barge, two Mulitcats and one tug, Jee’s press release reads.

Jee is the UK’s independent multi-discipline subsea engineering and training firm with experience in integrated subsea projects from concept, through to installation, and decommissioning.
