The AWQ-8/32-MP is a AWQ Split-Type Underwater Split In-Line Male Plug (AWQ-8/32-MP), featuring 8 high-power contacts (600 V / 10 A) and 32 signal contacts (250 V / 5 A) — 40 contacts total — in a single connector body rated to 600 Bar (6,000 m depth) mated. The AWQ-MP (Male Plug) is the cable-terminated in-line half of the split-type connector pair. It mates with the AWQ-S-BC (Split Bulkhead Connector) mounted in the equipment panel or junction box. The "split" design means the connector body separates into two halves for cable installation around existing cable bundles — eliminating the need to thread cables through a connector before termination. This high-density split-type design is the industry standard for ROV umbilical midpoint connection, subsea junction box flying lead termination, and multi-circuit subsea control system wiring.
At a glance: 8 power contacts (600 V / 10 A) + 32 signal contacts (250 V / 5 A) | Total 40 contacts | Mated 600 Bar | Open-face 400 Bar | Split body — field-installable without cable threading | Wet matings >500
Key Design Features
- Split Body — Field-Installable: The AWQ connector body separates into two halves, allowing installation onto existing cable bundles without removing connectors or cutting cables — essential for topside repair and modification of live umbilical systems.
- 8 Power + 32 Signal Contacts in One Connector: Eliminates the need for separate power and signal connectors on multi-circuit umbilicals — reduces panel complexity, weight, and penetration count.
- 600 Bar Mated Pressure: Full work-class ROV depth capability (6,000 m / 8,700 psi) for all standard offshore oil & gas and scientific applications.
- 400 Bar Open-Face Rating: AWQ-MP and AWQ-MP-D can be lowered to depth unmated; the bulkhead face is also rated open-face, enabling staged deployment of umbilical systems.
- Dual-Voltage Contact Arrangement: Power contacts (600 V / 10 A) and signal contacts (250 V / 5 A) are segregated within the connector body to prevent crosstalk and maintain signal integrity on low-level sensor channels.
- Gold-Plated Contacts: Contact resistance <0.01 Ω; insulation resistance >200 MΩ across all contact pairs.
- Chloroprene Rubber Body with 316 SS Shell: Flexible body for dynamic umbilical service; corrosion-resistant hardware for long-term seawater exposure.
- >500 Wet-Mate Cycles: Wiper seals protect all 40 contacts during each underwater mating cycle.
- Locking Sleeve (AWQFBLS/AWQMLS) Mandatory: Always install matching locking sleeves before deployment (sold separately — see AWQ Locking Sleeve listing).

Why Choose the AWQ-8/32-MP?
Split-Body for Field Installation and Repair
The defining advantage of AWQ split-type connectors is the ability to install them onto cables that are already wired, bundled, or in-situ — without removing the cable from service. This is critical for field repair of damaged umbilicals and modification of existing subsea control systems without complete system downtime.
40-Circuit Combined Power and Signal
Combining 8 power and 32 signal contacts eliminates the need for multiple separate connectors on multi-function umbilicals. This reduces panel size, total weight, and the number of potential leak paths through equipment housings.
600 Bar / 6,000 m — Work-Class Depth Coverage
The AWQ series is rated for all standard oil & gas operating depths and scientific ROV dive profiles. Every connector is pressure-tested before shipment; certificates are available for operator approval programmes.
Dual-Voltage Design Preserves Signal Integrity
Power and signal contacts are physically segregated within the body, providing inherent EMI shielding between high-current power circuits and low-level sensor signals — avoiding the need for external signal conditioning or ground isolation at the termination point.

Frequently Asked Questions
Q: What does "split-type" mean?
A: The AWQ connector body is manufactured in two halves that separate along a longitudinal split line. This allows the connector to be installed around an existing cable bundle — you do not need to thread the cable through the connector body. Essential for field installation and repair of in-service umbilicals.
Q: How many contacts does the AWQ-8/32 have?
A: 8 power contacts (600 V / 10 A) + 32 signal contacts (250 V / 5 A) = 40 total contacts.
Q: What is the rated depth and mated pressure?
A: 600 Bar (8,700 psi) mated (6,000 m depth equivalent). Open-face rating is 400 Bar (5,800 psi).
Q: Is a locking sleeve required?
A: Yes — mandatory. Never deploy an AWQ connector without the AWQFBLS (female) and AWQMLS (male) locking sleeves installed. Locking sleeves are listed separately in our catalogue.
Q: Can power and signal circuits be mixed in the same connector?
A: Yes — this is the primary design advantage of the AWQ series. Power (600 V / 10 A) and signal (250 V / 5 A) contacts are segregated within the body to prevent crosstalk. Do not exceed the individual contact ratings.
Q: What is the difference between MP and S-BC?
A: AWQ-MP (Male Plug) is the cable-side in-line plug. AWQ-S-BC (Split Bulkhead Connector) is the panel-mounted fixed half. They mate together — one MP plugs into one S-BC.
Q: How many wet-mate cycles are rated?
A: >500 wet-mate cycles. Inspect and clean contacts every 50 cycles or annually.
Q: Are matched MP + S-BC + dummy plug + locking sleeve sets available?
A: Yes — contact [email protected] for complete system sets with matched components and optional factory-terminated cable assemblies.
Q: Can you supply custom AWQ configurations?
A: Yes — non-standard power/signal contact ratios, shell materials (titanium), and pressure test certificates are available on request. Specify your wiring requirements and operating conditions for a quotation.
Q: Are pressure test certificates available?
A: Yes — batch or per-unit hydrostatic pressure test certificates to 600 Bar are available for operator approval programmes.
Installation, Mating & Maintenance Guidelines
Split-Body Field Installation
(1) De-energise all circuits before connector installation. (2) Separate the AWQ body into its two halves along the split line using the body separation tool. (3) Lay the two halves around the cable bundle — do not bend or kink individual conductors during installation. (4) Terminate conductors to the correct numbered contacts per the wiring diagram; use a calibrated crimping tool for the contact crimp size specified. (5) Close the two body halves and secure all body fasteners to the specified torque. (6) Install the coupling nut and mate with the counterpart. (7) Install AWQFBLS/AWQMLS locking sleeves — mandatory before deployment.
Mating Procedure
(1) Inspect all contacts and O-rings. (2) Apply silicone grease to O-rings only — not to contact faces. (3) Align guide pin with guide socket and insert with a single smooth stroke. (4) Thread coupling nut finger-tight then to specified torque. (5) Install locking sleeve until positive click confirms engagement. (6) Conduct insulation resistance test (≥200 MΩ at 500 V DC) before energising. (7) Log the mating cycle number against the connector serial number.
Storage & Maintenance
Rinse with fresh water after seawater exposure. Store with dummy plugs installed and locking sleeves disengaged. Inspect split-body seam integrity annually — replace if cracking or water ingress is detected. Replace O-rings every 2–3 years or if compressed permanently. Replace contacts showing pitting or contact resistance above 0.05 Ω. Return to RV Power Group for factory split-body re-sealing if body seam integrity is questionable.
