Surrey based Planet Ocean ltd is supplying a TRIAXYS directional wave buoy to provide vital data for the new replacement Forth River Crossing.
The 1m diameter buoy, manufactured in British Columbia by AXYS Technologies Inc, will provide wave height and direction information during all phases of the construction and maintenance of this significant infrastructure project.
The Forth Replacement Crossing (FRC) is being delivered by Transport Scotland on behalf of the Scottish Government. It is a major infrastructure project for Scotland, designed to safeguard a vital connection in the country's transport network.
The solar powered buoy measures movement using a combination of six sensors and computes on board, the wave height and direction information along with energy spectra, sea surface temperature and GPS position before sending the information ashore to the FRC control room by VHF data link, where it will be used for obtaining wave height data for analysis and real time decision making.
The builders, Forth Crossing Bridge Constructors (FCBC) consortium's mission is to build a new bridge across the Firth of Forth in the area to the west of existing road bridge. The construction methods require the movement of a significant amount of material and equipment from shore to the various off shore sites and then lift these in to place on the structure. Many of these operations, primarily Ro-ro transfers of equipment and heavy lifting have limits for wind and sea states. Whereas good wind data is available no wave height information is available in the construction area and the bridge builders need to verify the actual maximum wave heights compared with the theoretical figures and subsequently use the combination of the data for real-time operational decision making.
Terry Sloane, Planet Ocean's managing director comments that this is the most recent of a number of sales into the marine construction industry in the last 18 months with the major growth coming from the offshore wind farm sector.
