High-Load UTH
Umbilical termination head (UTH) assemblies make it possible to terminate umbilical lines and provide multiple connections for chemical, hydraulic, electrical and fibre optic services subsea.
Due to its unique ‘external load by-pass’ (ELB) retainer mechanism, all external loads are disconnected from the MQC locking mechanism and re-directed straight on the host structure allowing for far greater tie-in loads.
This particular design houses a vast array of functions including 14 hydraulic lines, 6off bulkhead connectors with 3off 1in-2out FACTs, with all 15m of service loop cabling contained within the frame allowing for greater protection through all phases of its life cycle.
