DescriptionCategory

FULL PLOUGH BURIAL - Full plough cable burial expected to target

REDUCED VARIABLE PLOUGH BURIAL - Target burial cover depth might not be achieveddue to seabed conditions. Reduced cable cover depth predicted > 0.5 m

POOR/VARIABLE PLOUGH BURIAL - Poor burial, to a predicted < 0.5 m cover depth

PLOUGH OVERBURIAL - Potential Cable overburial

CONTRACT SPECIFIC BURIAL - Cable burial to a specific target cover depth

Description

PLOUGHABLE / PLB ATTEMPT:No significant risk to the burial equipment due to seabed conditionsCHANGE IN BURIAL CONDITIONS (CBC):Change in seabed texture and/or topography. A plough/PLB attempt will be madeand feasible burial (>0.5m) anticipated although target burial may not be reached.RISK OF NON-BURIAL (RNB).Moderate risk of damage to the cable and/or burial equipment due to seabed conditions;potential damage repairable onboard, using shipboard spares. A plough/PLB attempt willbe made although there is a Risk of Non-Burial (Surface Lay) or burial to <0.5m.SURFACE LAY / UNPLOUGHABLE / NO PLB ATTEMPT:High risk of damage to the cable and/or burial equipment due to seabed conditions;potential severe damage not repairable onboard using shipboard spares.

Hazards/Remarks:

In the northern charted inshore area, the route enters seabed comprising medium SAND overlying subcropping ROCK

with megaripples, coast parallel sediment structures (0.4 m in height) and isolated boulders. Towards the southeast, the

route crosses areas of outcropping ROCK and areas of medium SAND overlying subcropping HARDGROUND with

isolated boulders. The central area is dominated by very soft CLAY over SAND/GRAVEL to very loose to medium dense

SAND in the southern part. These sediments are overlying subcropping HARDGROUND (very dense to cemented

SAND) in the southernmost area. Slopes are in general very gentle, except when crossing a local slope edge, where

slopes are moderate. Several converging cables and potential cable debris are observed in the magnetometer and

sidescan sonar data near the landing point.
