Subsea Distribution & Accumulation

J+S has 20 years of experience in design, manufacture, repair and replacement of a range of Subsea Control Systems equipment.

This includes electrical, hydraulic and combined systems on both small and large scales.
SUBSEA DISTRIBUTION & ACCUMULATION ASSEMBLIES
Modular Subsea Distribution Solutions.
Subsea Distribution Assemblies

J+S has produced a range of Subsea Distribution Assemblies to meet bespoke client requirements for hydraulic, chemical and electrical distribution.

Modular Subsea Distribution Solutions.

Modular design configured for various subsea applications.

Modular design
J+S has produced a Subsea Distribution Unit (SDU) design that is modular in construction. This approach makes it easier and more cost-effective to reconfigure the unit for different applications, where different numbers of electrical and hydraulic circuits are required.

Individual sub-assemblies can be removed without recovering the compete SDU.

We work closely with our customers

J+S designs, manufactures, tests and supports installation of the SDU including electrical and hydraulic interfaces and jumpers whilst maintaining physical and functional fidelity with previously installed equipment.

We work closely with our customer at each step in the project, to ensure that we deliver the right product at the right time and right price. Where appropriate, instead of re-using inductive couplers, we use subsea matching transformers, designed and manufactured by J+S for this purpose.

Key Features
  • Modular design for re-use in a variety of applications
  • Oil-filled, pressure compensated electrical fuse chamber
  • Two electrical input channels
  • Up to ten electrical outputs per channel
  • Multiple HP and LP hydraulic inputs
  • HP and LP outputs configured to client requirements
  • Mechanical strain relief in excess of 10 tonnes on input umbilicals dependent on umbilical specification.
  • Frame constructed in mild steel with subsea paint finish
  • Independently retrievable EDB
  • Depth rated to 300m
  • Tailored to existing footprint requirements
SUBSEA ELECTRICAL DISTRIBUTION UNIT

J+S have designed and delivered a range of bespoke Subsea Electrical Distribution units for use as a junction box within a larger system, Subsea Umbilical Termination or stand-alone plug and play requirements.

Numerous applications

The Electrical Distribution Box can be used in numerous applications and has several interfacing options such as subsea connectors or J+S high integrity penetrator technology.

This provides a versatile interfacing solution for multiple subsea connection points.

Key Features
