Offshore Mooring System Engineering

Client challenge

An offshore project required an engineered mooring arrangement capable of maintaining the required offshore position while accounting for the interfaces between the buoy, chain, wire rope, anchors, shackles and swivels.

The client required a coordinated technical package that could be used for component selection and offshore installation planning.

Mooring-system components

The following components were coordinated as elements of a single connected load path.

  • Buoy
  • Chain
  • Wire rope
  • Anchors
  • Shackles
  • Swivels
CITA solution

CITA Engineering reviewed the proposed mooring configuration and developed the mechanical engineering requirements for the principal mooring components.

The work included chain and anchor selection, wire-rope specification, definition of shackle and swivel arrangements and preparation of engineering and installation drawings.

The component interfaces were reviewed as a complete load path rather than as isolated items, helping to ensure compatibility between the selected equipment and the proposed installation arrangement.

Engineering scope
  • Review of the proposed mooring configuration
  • Chain selection
  • Anchor selection
  • Wire-rope specification
  • Shackle arrangement
  • Swivel arrangement
  • Review of component interfaces
  • Preparation of engineering drawings
  • Preparation of installation drawings
  • Support for procurement and installation planning
Systems integration

The principal mooring components were reviewed as a connected load path, helping to ensure that the selected items were compatible with one another and with the proposed offshore installation arrangement.

Outcome

The client received a coordinated mooring-engineering package supporting procurement, component integration and offshore installation planning.
