Subsea engineering services
Full-system engineering for subsea sensing and connectivity
DepthLink develops application-specific proximity switches, cable assemblies and sensor solutions for pressure-rated underwater systems. We review the complete signal path, not only the individual component.
Engineering scope
One engineering review across the complete subsea interface
Subsea sensing problems rarely stop at the sensor body. Mounting envelope, target material, switching logic, connector interface, cable construction, termination, pressure boundary and documentation all influence the final result. DepthLink brings these requirements into one coordinated specification.
- Review
- Application, environment and system interfaces
- Configure
- Mechanical, electrical and connection options
- Integrate
- Sensor, connector, cable and termination
- Verify
- Inspection, testing and project documentation
Custom engineering capability
Engineering support around three core product platforms
Standard products provide the starting point. Dimensions, interfaces, materials and terminations can then be reviewed against the actual subsea assembly and operating conditions.
Application-specific proximity and limit switches
Switch platforms can be adapted around the mechanical envelope, sensing target, switching function and subsea connection method required by the equipment.
- Thread, housing and mounting configuration
- Target geometry and sensing-distance review
- Switching logic, load and circuit requirements
- Axial, right-angle, connector or cable-tail interfaces
- Material and pressure-rating review per configuration
Custom cable assemblies and subsea terminations
DepthLink can specify the cable and connector arrangement as a complete assembly, including mixed interfaces and equipment-specific breakouts.
- Single-ended, double-ended and open-tail assemblies
- Wet-mate, dry-mate and equipment connector integration
- Custom lengths, conductor layouts and shielding
- Overmoulded transitions, breakouts and strain relief
- Continuity, insulation and pressure-test requirements
Custom sensors and integrated feedback solutions
Where a catalogue component does not fit, DepthLink can review a custom sensing package or integrated feedback interface around the equipment, environment and signal requirements.
- Position, presence and end-of-travel sensing
- Valve, actuator, tooling and mechanism feedback
- Space-constrained and non-standard installation envelopes
- Sensor-to-connector and sensor-to-cable integration
- Prototype, qualification and production documentation scope
Engineering process
From application requirement to verified configuration
The scope scales from a component selection review through to a fully defined, tested and documented application-specific assembly.
Define the operating case
Pressure, media, temperature, mechanical envelope, electrical load, duty cycle and installation method.
Review the interfaces
Sensor target, mounting, connector family, pin allocation, cable construction and termination requirements.
Confirm the configuration
Drawings, materials, ratings, test scope, documentation and project-specific acceptance criteria.
Build and verify
Manufacture, inspection, electrical testing and pressure testing where included in the agreed scope.
Project deliverables
Documentation matched to the engineering requirement
Deliverables are agreed per project. DepthLink can support the records needed for design review, manufacturing release, equipment integration and final acceptance.
- Configuration and part-number definition
- Dimensional or interface drawings
- Pin allocation and wiring information
- Material and component records where specified
- Electrical inspection and test results
- Pressure-test records where included
- As-built assembly documentation
- Application and installation notes
