  • Designs includes splash zone venting, weights, closing, sealing, pull-of features as applicable.
  • Protect coating on equipment landed on and pulled along the seabed or in rock dumps.
  • Snag point protection /elimination during installation operations.
  • If required, includes impact protection covers and similar.
  • Subsea installable Ucaps including applicable ROV tooling is also available.
  • Ucap for seabed suction prevention (e.g. subsea DMA and clump weights) are available on request.
  • Existing designs adopted and modified to suit any new equipment and/or requirements prior to manufacturing.

The following Ucap types including applicable transport, handling and outline procedures are available:
