Rothesay Ferry Terminal - Scour Baffle Installation
Rothsay harbour lies on the Isle of Bute on the west coast of Scotland. It is a ferry port and also serves cruise ships, fishing vessels and a marina for leisure craft.
The harbour uses scour baffles to help reduce or remove vibrations caused by the sea conditions on the pier legs. Correctly installed baffles can help to extend the life of the pier structure and provide a safer platform during extreme weather events. Given that the harbour lies on an island, and is the main supply route for essential supplies, it is particularly important that the pier be protected.
RockSalt’s on-site engineering team utilised a variety of our in-house tooling including our subsea chain saw, grinders, hydro-tights and wet welding equipment. Works included the successful construction of the scour baffle and supports, grouting, wet welding, hydro tensioning and removing the pier’s green heart piles.
RockSalt also provided diving services for a three month period. The diving team used two dive systems, one with a three diver panel. Both systems were operated from the quayside. Using two dive systems to allow a more efficient approach to the diving activities. Several external factors such as the tides, ferry turnarounds and surface weather conditions impacted on the project schedule, so it was decided to utilise two teams and a combination of day and night working.
RockSalt was contacted directly by the client to undertake the works after previous contractors had been unsuccessful in executing the works. We recognised that it was essential to establish positive communication with the client to ensure that works were back on track as quickly as possible.
RockSalt have extensive experience on construction projects in-shore and near-shore. Our knowledge, in-house engineering and supply chain provide the necessary infrastructure and capability to allow us to undertake complex and challenging work scopes.
