Protection Requirements for Submarine Cables
Cable Burial Machine Various types of cable burying machines,
For protection of submarine cable against fishing activities, burial of cable up to 1 meter in the seabed is normally considered adequate in South East Asia region. In Singapore and Hong Kong where protection of cable against ship anchors is necessary, cable is usually buried to a depth of 6 to 8 meters in the seabed where it is soft and 4 meters where it is hard. For some specific reasons in certain areas e.g. where special fishing technique is employed or where there is sand movement, cable burial of depth greater than 1 meter may be required for protection against fishing.
including plowing and water jetting machines have been developed for burying of cables up to a depth of 3 meters. For burial of cable up to 10 meters, a special purpose built barge equipped with deep cable burial injector and rock-cutting machine will be required. The barge “Cable Protector” is built for the purpose of burial of cable up to 10 meters. Cable Protector is a “dynamically positioned” state-of-the-art deep burial-laying barge. This sophisticated barge is also equipped with 6 points mooring system, 2 supplemented CABLE PROTECTOR CLASSIFICATION / DIMENSIONS: Year built: 2001 Classification: LRS / DP (AM) Port of Registry: Singapore Length: 70.0 meters Beam: 24.2 meters Depth: 4.88 meters Draft in Service: 3.16 meters Gross Tonnage: 2935 tons Accommodation: 44 berth
