The design is based on two requirements, which are reliability and ease of use. For the implementation of these parameters, only proven technology and components were used. As a result, this system allows the customer to operate easier and quicker compared with existing systems.

The modularity of the approach ensures different versions without compromising the proven technology.

Key Features

  • Seawater depth up to 3.000 m
  • Operational interface for torque tool to ISO 13628-8 class 4
  • Normal operation torque 1.350 Nm (= max. setting of class 3)
  • Emergency break away torque 2.700 Nm (= max. setting of class 4)
  • Connection and disconnection at full working pressure possible (also emergency disconnection)
  • Hose bundle built by coiled single hoses, wrapped and protected against mechanical damage by 5 mm thick high densitypolyethylene spiral
  • HFL bend radius min. 600 mm + 25% for dynamic movement. Central stainless steel wire for pull loads up to 5000 N
  • Hose bundle terminated in strain relief flange and single line clamping flange, coupling elements equipped with weldedtubing, bent into position to meet single hoses torsion and torque free

Project-Related Features

  • Population of elements (up to 14 elements, see population table)
  • Strain relief (according to customer requirements)
  • Working pressure up to 69 MPa (10.000 psi), line sizes ¼” – 1”
  • Jumper length adapted to customer requirements
  • High collapse resistant hoses available (HCR)
  • Umbilical with outer sheathing instead of hose bundle with spiral available

Operation Sequence

  • Transport and placement of MQC free half by ROV to fixed half and dropping in position
  • Prepositioned unit is driven to connect by activation of rotary action of torque tool
  • The fine centring and mating of coupling elements is done without further action by the ROV operator
