Full range of product offerings for connector terminations, armor terminations, break-a-way units and splice canisters.
The primary field installable solution is the SEACON Multi-Plex System (MUX) which consists of a positively pressurized rugged connector solution, an underwater Armor Termination Assembly (ATA) and a Breakaway Unit.
In recent years the search for oil has required operations in progressively deeper waters by mobile offshore drilling units. Drilling at these depths places strong demands on equipment, particularly the cable and connectors that link subsea operations to the surface.
TE Connectivity (TE)'s SEACON range of MUX systems consist of 1 Atmosphere and Positively Pressurized connector solutions as well as the underwater cable termination system which consists of the Armor Termination Assembly (ATA), Breakaway Unit connector.

Field Installable MUX system
The MUX connector is an electro-optical mechanical termination that contains an integral system that does not rely on separate external compensator systems to apply a constant overpressure (internal pressure greater than external pressure) to the end of the cable and termination volume. The overpressure helps to prevent water intrusion into the termination chamber that could be caused by flooding of the conductor strands or by seal failure. In the cable termination system the ATA is affixed to a clevis (padeye) at a convenient location on the BOP (Blow Out Prevention) stack while the MUX connector mates to either a transformer module, crossover or directly to the subsea electronics module (pod). The orientation aspect that can be a problem with a conventional connector is eliminated due to the breakaway unit that interfaces the ATA with the BOP, enabling a connection in 90 degree intervals.

Field Installable MUX System
FEATURES
- Lighter, more manageable connector than the legacy connectors
- Separate armor termination function from electrical connector function and a controlled breakaway function
- The connector provides visual verification of correct pressure over ambient
- It also includes the ability to electrically check for fluid contamination without opening the connector
Breakaway Unit
The Breakaway Unit helps provide a means of reducing the damage caused when extreme MUX cable tension breaks a termination. The unit is designed to anchor an armor termination unit to a clevis mount at the subsea end of a riser or control system framework. The breakaway concept is based on shear pin technology. Shear pin material with a low ultimate/yield strength ratio is used to increase accuracy of targeted breaking load.

Armor Termination Assembly (ATA)
The ATA allows contra-helical armor to be terminated a distance away from the end electrical connection of a MUX umbilical cable. This makes terminated cable handling much more manageable, and provides an emergency breakaway point which helps preserve Subsea Electronics Module (SEM) integrity. The interior armor plug is mechanical, no epoxy is used. With this technology, we are able to provide solutions that can be up to or exceed 75% cable breaking strength. Contact our team to find out more.

Field Installable Termination Assembly (FITA)
The FITA connector is an electrical termination that maintains a constant positive pressure inside the oil-filled connector cavity. Positive pressure, maintained at 60 psig using a spring-loaded piston, deters water ingress from conductor interstices and other sources. Inside the connector, advanced conductor booting technology helps assure functionality even when the FITA is water-flooded. The FITA is field installable and testable. Dual barrier seals are used throughout the connector.

MSSQ Flanged Connector Receptacle (MSSQ-FCR)
The Metal Shell Series Q Flanged Connector Receptacle (MSSQ-FCR) has been part of TE's SEACON standard product line for over 30 years and has been used for connecting to MUX cable connectors in the drilling industry for more than 20 years. The receptacle mounts to existing hole penetrations on many subsea modules.
The connection side of the receptacle interfaces with the SEACON standard MSSQ cable connector plug line. Typical connection is to a MSSQ positive pressure compensated MUX cable connector. The MSSQ series of MUX terminations is available with electrical contacts only and electrical-fiber optic hybrids. Standard body material is passivated 316 stainless steel although other materials are available upon request.

MSSQ-CCP
The Metal Shell Series Q Cable Connector Plug (MSSQ-CCP) connector is a MUX cable termination that maintains a constant positive pressure (max 60 psig / 4.0 Bar) inside its oil-filled volume via a spring-loaded piston. This helps prevent water ingress to internal conductor elements that could create electrical short circuits. Additional internal water barriers are formed through advanced elastomeric boot sealing technology to seal each individual cable element. This helps ensures full functionality even in a major event where the internal oil volume becomes completely water flooded.
The MSSQ-CCP is field installable and testable. It is currently available in both all-electric and hybrid (electro-optic) configurations. The overall connector designs are modular, where only the cable termination element needs to be specifically designed to suit the characteristics of different cables.
