DepthLink builds mixed-brand subsea cable assemblies using wet-mate and dry-mate connectors from Seacon, MacArtney, CRE, Glenair, and Hydro Group. Select a connector brand below to explore compatible models, configure pin counts, and request a custom subsea cable assembly built to your specification.
Most subsea failures begin at the interface. DepthLink approaches every subsea connectivity project from the surface control point to the subsea valve — designing connectors, cable assemblies, and feedback loops that function as an integrated whole, not isolated components.
Our engineering team reviews your interface requirements, specifies the complete signal chain — including wet-mate connectors, ROV-operable cable assemblies, position sensors, and integration packages — and delivers a traceable, pressure-tested assembly with full documentation.
See System Architecture →From subsea oil and gas production infrastructure to nuclear cooling water circuits and offshore wind interconnection — DepthLink subsea cable assemblies, connectors, and switches are engineered for the environment, not adapted for it.
Real-time subsea valve position feedback at depth. Hermetically-sealed proximity switches, wet-mate connectors, and integration packages for gate valve and choke valve monitoring on subsea Christmas trees and manifolds.
View Application →End-of-travel and partial stroke feedback for subsea hydraulic actuators. Closed-loop confirmation that actuation has occurred, using DepthLink position sensors and pressure-rated cable assemblies.
View Application →Subsea Christmas tree instrumentation, manifold control systems, and umbilical termination assemblies. Wet-mate and dry-mate connector solutions for SCM, SJB, and HDU integration on offshore production fields.
View Application →Foundation monitoring, inter-array cable interfaces, and subsea junction networks for fixed and floating offshore wind assets. ROV-operable connectors and pressure-tested cable assemblies for turbine foundation and substation interconnection.
View Application →Qualified nuclear-grade penetrators, hermetically-sealed switches, and sensor assemblies for nuclear cooling water systems — supplied with full material traceability and 316SS / Inconel construction options.
View Application →When a North Sea operator needed a wet-mate subsea connector solution for a critical valve monitoring application outside standard catalogue spec, DepthLink designed, built and pressure-tested a custom subsea cable assembly in 12 weeks — rated to 3,000m water depth, with integrated position sensor feedback and a full as-built documentation package.
No sales intermediary. Technical enquiries are handled by the engineers who will specify and build your subsea cable assembly. Questions get technical answers, not marketing ones.
We don't quote part numbers without context. Our team reviews your interface requirements, depth rating, environment, and application before specifying connectors, switches, and cable assemblies — reducing errors and rework risk.
Material certificates, dimensional inspection records, pressure test reports, and as-built drawing packages come with every subsea assembly — no additional charge for documentation that should always be there.
We respond to every technical enquiry the same day. Our subsea connector and cable assembly supply chain is built for speed — from first contact to delivered, tested assembly, lead times are short by design, not by exception.
Pin count, depth rating, mating cycles, and sealing mechanism — a practical guide for engineers specifying subsea connector interfaces from Seacon, MacArtney, and Glenair.
A comparison of subsea position sensing technologies — reliability, signal integrity, and maintenance implications at depth for proximity, Hall-effect, and inductive sensors.
For fast-track subsea projects, pre-qualified integration packages reduce interface risk between connectors, sensors, and control systems. Here is the engineering case for how and when they apply.
