Swathe Services and Falmouth Divers deliver energy to remote community

Swathe Services and Falmouth Divers deliver energy to remote communitySwathe Services was recently commissioned by Falmouth Divers Ltd to assist on a 4km submarine power cable installation to a remote island community on behalf of one of their clients, in Pembrokeshire, Wales.


Working from the Grey Bear, a landing craft type vessel provided by Falmouth Divers, Swathe Services conducted a heave compensated Single Beam Echo Sounder (SBES) survey of the proposed cable route. The SBES data was processed on site and a Digital Terrain Model (DTM) of the cable route was produced. On selection of a route, tidal flow measurements were taken to allow the cable lay vessel to plan the course & speed of the lay. During the cable lay Swathe Services provided full course positioning support aboard the cable lay vessel MCS Ailsa and logged the as-laid cable position .

Swathe Services were able to provide a complete support service to Falmouth Divers with the utilisation of their extensive pool of survey equipment which included Odom MKII Single Beam Echo Sounder (SBES), Hemisphere vector DGPS sensor, a Valeport SVP profiler, and a TSS DMS-05 Motion Reference Unit (MRU). Vessel navigation and data acquisition were performed in QINSy v8 hydrographic software.

"On completion, an excellent as laid cable survey report was produced complete with a suite of drawings presented to a very high quality. We were very pleased with the professional & flexible attitude of the Swathe Services site personnel & equally with the consultation & advice provided early in the project that allowed Falmouth Divers Ltd to offer a full turn-key package to our Client."
