Seabed Preparation

  • Seabed Preparation – Levelling and/or Pre-Sweeping:
    • Providing solutions to seabed preparation in order to reduce risk to cable installation and achieved burial depth of time.
    • Levelling and/or Pre-Sweeping.
    • Pre-Sweeping of mobile seabed’s including sand-waves (in line with permitting requirements for maximum dredging and volume constraints).
    • 3D migration analysis to reroute cables, optimise crossing angles and avoiding number of sand-waves, mobile sections, crests and troughs with wrecks and obstacles.
    • Assessment of seabed preparation (by dredging or/and deeper initial installation), with cost of depth of burial maintenance costs.
