Harness Design and Manufacture
When designing an underwater cable harness, there are some factors which need to be considered, and we have produced the following list as a guide for customer information:Component considerations:- Electrical requirements- Mechanical considerations- Quality requirements- Reliability- Design redundancy (contact count)- Connector selection (type and form)- Locking requirements- Backpotting requirements- Waterblocking in moldings- Cable specification- Cable jacket material and compatibility with elastomers- Abrasion resistance- Stiffness profile at termination- Connector format (straight or right angle)- Molding format (straight or at an angle)- Clearance allowance for molding and cable routing- Elastomer compatibility (eg oil filled units)- Metalwork selection re: corrosion and cathodic delamination- Surface finish for metalwork as appropriateOperational considerations:- Operating depth profile (not just max. depth)- Tensile loads- Torsional loads- Bending loads- Bend control requirements (to limit bending at termination)- Deployment and recovery loads- Dynamic loading-Flow turbulence effects.

Modular Connectorized Distribution Unit
MCDU
The Modular Connectorized Distribution Unit (MCDU) is a modular family of factory-qualified subsea distribution units that provide oil-filled, pressure-balanced junctions for flexible underwater configurations.A new configuration has recently been introduced with a lighter, more cost-effective frame, highly visible ROV lifting handles, and wide openings to facilitate installation and removal of the housing. The compact frame design negates the need for lifting wires, making it easy for ROVs to install and retrieve the unit from the sea floor.
