Core offering

Subsea Energy Solutions designs, manufactures, and supplies a proprietary range of 22+ engineered subsea cable protection and SURF (Subsea, Umbilicals, Risers, Flowlines) product lines — including bend stiffeners, bend restrictors, buoyancy modules, clamps, seals, and pull-in equipment — custom-fabricated from polyurethane, syntactic foam, and high-performance metals for offshore oil & gas, wind, wave, tidal, nuclear, and mining sectors. The company also delivers end-to-end engineering services covering CAD design, fabrication, project management, site support, and testing for clients operating in water depths up to 3,000m+.

Product overview

Subsea Energy Solutions offers a comprehensive portfolio of 22+ engineered product lines for subsea cable protection and SURF (Subsea, Umbilicals, Risers, Flowlines) systems. The product portfolio centres on the SUB-FLEX™ flexible cable protection system (combining bend stiffener and restrictor), paired with the SUB-VBR™ vertebrae bend restrictors for overbend protection. Supporting products include SUB-BSR-S/D™ bend stiffeners (static and dynamic) for cable termination protection, SUB-DUCT™ rigid duct protection, and SUB-BALLAST™ and SUB-BUOY-SBM™ buoyancy/ballast modules for pipeline and cable stability. The clamping suite comprises SUB-LATCH™ J-tubeless latches, SUB-CLAMP™ subsea clamps, SUB-CLAMP-SWIVEL™ swivel clamps, SUB-HANG™ hang-off clamps, SUB-PIGGY™ piggyback clamps, and SUB-CENTRALISERS™ centralisers. Sealing products include SUB-SEAL™ J-tube seals and SUB-BUNG-OWF-S/T™ diver-installed and topside grouting bungs. Pull-in equipment includes SUB-HEAD-F/R™ flexible and rigid pull-in heads. Speciality products round out the range with SUB-VSS™ vortex shedding sleeves, SUB-BOX-C™ cobra head spacing boxes, SUB-SRJ™ subsea repair joints, and Rotary Unions. All products serve the oil & gas, offshore wind (fixed and floating), wave & tidal, and nuclear sectors, with in-house design, production, and project management capabilities.

Products and services

• SUB-LATCH™ J-tubeless Latch J-tubeless mechanical latching system for offshore wind applications, fully adjustable for varying cable installation catenary and pull-in load scenarios. Pairs with SUB-FLEX™ cable protection systems or SUB-VBR™ bend restrictors for fixed bottom J-tube or J-tubeless cable protection.
• SUB-VBR™ Vertebrae Bend Restrictors Interlocking vertebrae-type bend restrictors for overbend protection of cable, umbilical, riser, hoses, or thermoplastic composite pipes, featuring articulated half-shell design with positive mechanical locking when subjected to external load.
• SUB-FLEX™ Cable Protection System Flexible cable protection system for dynamic and static subsea applications, combining bend stiffener and bend restrictor functionality. Under low load it operates as a traditional bend stiffener with internal compression discs providing damping; under high load it operates as a bend restrictor with guaranteed lock-out radius. Fully split for retrofit/repair use.
• SUB-BSR-S™ Static Bend Stiffeners Bend stiffeners for static subsea cable and pipeline protection at termination points on fixed structures, with split options available for retrofit applications.
• SUB-BSR-D™ Dynamic Bend Stiffeners Highly engineered dynamic bend stiffeners designed to reduce bending stresses throughout the design life at connection points to fixed structures under dynamic loading. FEA-optimised tapered polyurethane cone geometry, fatigue-rated.
• SUB-BALLAST™ Modular Ballast Solutions Modular ballast solutions for subsea cable stabilisation and weighting, providing counter-balance weight during omega lay deployment of repair joints and thermoplastic composite pipe (TCP) on-bottom stability.
• SUB-BUOY-SBM™ Subsea Buoyancy Modules Subsea buoyancy modules manufactured using dedicated mould tooling with syntactic foam and polyurethane skin, engineered for full ocean depth and providing pipeline and riser buoyancy support.
• SUB-SEAL™ J-tube Sealing Systems J-tube sealing systems preventing water ingress at the interface between cable, umbilical, riser, hoses, or thermoplastic composite pipes and subsea J-tubes, using pressure-rated elastomeric elements.
• SUB-CENTRALISERS™ J-tube Centralisers J-tube centralisers for guiding and centralising cables, umbilicals, risers, flowlines, hoses, and thermoplastic composite pipes within subsea J-tubes during installation.
• SUB-HANG™ Topside Hang-Off Clamps Topside hang-off clamps providing structural support between cables, umbilicals, risers, hoses, or thermoplastic composite pipes and the topside J-tube flange.
• SUB-PIGGY™ Piggyback Clamps Piggyback clamps for securing secondary small diameter service pipes, cables, or umbilicals to primary pipelines or cables during simultaneous laying operations.
• SUB-VSS™ Vortex Shedding Sleeves Sleeves to mitigate vortex-induced vibration on subsea cable protection systems, offered in polyurethane VIV strakes, roto-moulded strakes, and thermoformed strakes. Applied to pipelines and cable protection systems.
• SUB-DUCT™ Rigid Cable Protection Duct Rigid cable protection duct systems for subsea cable routing and protection against dropped object impact and abrasion due to crossings, rocks, and reefs, with modular interlocking design.
• SUB-CLAMP™ Subsea Clamps High-performance subsea clamping solutions for pipelines and cables, bespoke products designed for specific project requirements with heavy-duty forged or fabricated construction.
• SUB-CLAMP-SWIVEL™ Swivel Subsea Clamps Swivel clamps with 360-degree swivel capability for angular adjustment of cables, umbilicals, risers, flowlines, hoses, and thermoplastic composite pipes in subsea midwater column locations.
• SUB-BUNG-OWF-S™ Subsea Diver-Installed Bungs Diver-installable bungs for offshore wind foundation sealing, providing environmental seal within monopile J-tubeless cable entry holes during drilling operations.
• SUB-BUNG-OWF-T™ Topside Grouting Bungs Topside-installed grouting bungs for offshore wind transition piece to monopile grouting operations, featuring snorkel design for air venting during annular gap filling.
• SUB-HEAD-F™ Flexible Pull-In Heads Flexible pull-in heads providing a lifting point for umbilical pull-in operations through small radius J-tubes, with streamlined profile for smooth entry and integrated swivel option.
• SUB-HEAD-R™ Rigid Pull-In Heads Pull-in heads for rigid pipeline installation operations through large radius J-tubes, with welded connection to pipe end and bullnose profile for smooth entry.
• SUB-BOX-C™ Cobra Head Spacing Boxes Cobra head spacing boxes housing umbilical break-out connections including hydraulic pipe fittings, electrical joints, and fibre optic splices during subsea infrastructure terminations.
• SUB-SRJ™ Subsea Repair Joints Subsea repair joints for low and medium voltage cable connections, providing watertight mechanical and electrical connection for damaged subsea cable repair.
• Rotary Unions for Hose Reels (DSTI UK distribution) Rotary union systems for hose reel operations on vessels, providing multi-passage rotary unions for hydraulic, pneumatic, chemical, and other fluid services. Distributed in the UK by Subsea Energy Solutions as the UK distributor for DSTI.
• Subsea Engineering and Project Management Services Comprehensive engineering services covering 2D and 3D CAD design, fabrication, project management, site support, testing and calculations, and surface protection services — delivered as a stand-alone engagement or alongside product hardware supply to clients in oil & gas, offshore wind, and marine energy.
