The Project
JBS were contracted by Logi Point Polska to provide Sea Axe CFE equipment and operational team members for a project offshore Swinoujscie, North West Poland. JBS were contracted to locate a subsea fibre optic cable and then excavate the area to allow cable repairs to be completed. Water depth was 20 metres, and the equipment was deployed from the vessel Baltic Worker.
The Challenge
The fibre optic cable had very small diameter of 22mm, burial depth 3m with “as laid” survey data dating back to 1989. Client initially requested the JBS Sea Axe team to create a 3.2m deep x 16m wide trench over a 100m length. Bottom of trench width was 4.56m. Trench still had soft backfill so it was decided to increase the trench width at port and starboard side to approximately 20m wide at the top of trench. Sea Axe then went back to centre area and continued to excavate at “as laid” area.
The Solution
JBS Sea Axe team located the cable, completed the excavation to allow for diver access and cable repair. Project completed successfully and client delighted with the performance.
