This new device called the Cable Fish should lower costs by 75%
North Sea Systems, has just completed the first full scale trials of its CableFish at EMEC.
The final trial which began in November 2014 has been completed. The project was funded by Scottish Government through Marine Renewables Commercialization Fund (MRCF).
Cable Fish makes it possible to lay cable in currents up to 6 knots, whereas previous equipment was only effective in 2 knots of current
Here’s what the say about Cable Fish:
CableFish represents a new concept for the installation of cables in high flow tidal environments, which de-risks cable installation by providing continuous visual and position monitoring of the touchdown point (the point at which the cable meets the seabed), Carbon Trust’s press release reads.
The CableFish is attached to the cable, then rides down from the installation vessel to the touchdown point. Movements on the cable are controto lolled by a winch device.
The system is equipped with cameras, an altimeter, a motion sensor, a USBL beacon, and high power lights for night work. Real-time data is fed back directly into the installation vessels survey system.
ROV’s are usually used for cable installations, and they can operate in up to 2 knots of tidal flow. CableFish system operates in up to 6 knots of tidal, and does not require ROVs and post-lay surveys, which drives down the costs of cable installation, the press release reads.
