Terminations & Ancillaries

Terminations & Ancillaries

A crucial element of the umbilicals and cables we produce are the terminations and ancillary equipment. Most of the mechanical terminations are designed in-house and manufactured locally. Our customers benefit from being able to source the whole package (including umbilical, termination and testing) from one trusted supplier.

Our extensive range of terminations and ancillaries includes the following:

  • Armour body
  • Sleeves
  • Integration plates
  • Bend stiffeners (moulded, bolt-on, screw-on)
  • Vertebrae, segmented bend restrictors
  • Pull-In heads
  • Hang-off collars
  • Isolation kits
  • Termination assemblies (UTA, SUTU, TUTU, SDU)
  • Junction boxes and housings (hydraulic, electrical and optic)
  • Mounting frames
  • MQC plates
  • Stab-plates
  • Cobra heads
  • J-Tube seals
  • Buoyancy and ballast modules
  • Umbilical impact protection
  • Hose end fittings
  • Hydraulic couplers
  • Electrical connectors
  • Test kits
  • Flushing hoses
  • Cathodic protection
  • Abandonment kits
  • Installation reels, cradles, lifting beams, sling sets
  • Handling systems (HPUs, reelers)

Terminations & Ancillaries FAQs

An Umbilical Termination Assembly (UTA) or Umbilical Termination Head (UTH) is a fitting or assembly that is attached to the end of an umbilical cable, to provide a means of transferring loads (installation and operating) and services (fluids, electrical power, control signals and/or data) to a mating assembly mounted on the sub-sea equipment or surface facility.

A bend stiffener is a tapered moulding that adds graduated local stiffness to an umbilical cable, along the bend stiffener’s length. A bend restrictor (or bend limiter) is an interlocking assembly that prevents an umbilical from bending beyond a specific geometric limit: it constrains the extent of bending, rather than changing the umbilical’s effective local stiffness.

A Topside Umbilical Termination Unit (TUTU) is a surface module located on an offshore platform, floating production facility or vessel, that links a subsea umbilical cable to the facility's main control equipment. Its functions can be to connect services, to transfer power and fluids, to manage communications and data transfer, and/or to control pressures.

A Subsea Umbilical Termination Unit (SUTU) is a seabed structure that secures the end of a subsea umbilical cable and splits its internal lines to distribute services to the local underwater infrastructure. Its functions can be to anchor the subsea end of the umbilical cable, to distribute services (power, fluids, communications and/or data) to their subsea point of use, and/or to act as a hub for flying leads or jumpers to individual subsea devices.

A multi-quick-connect plate (or “MQC” plate) is a mechanical interface device that allows the connection and disconnection of an umbilical cable’s multiple services (power, fluids, communications and/or data) simultaneously, with a single motion. Typically, this is achieved by all of the individual couplers/connectors being installed on a matched pair of metal plates, with keyed pins and alignment guides to ensure correct matching of the plates and no cross-connection of the couplers/connectors, with a lever or handle (often ROV-compatible) to engage the MQC.
