Advanced pipe connection systems for Oil & Gas

Surface and subsea

Production and well intervention

Safe

Robust

Fast

Compact

Operation friendly

No special tools

Simplifying connections cuts offshore operation costs

OUR UNIQUE VALUE PROPOSITION

A novel pipe connection system specifically designed to make offshore installation safer and much faster. As the operational requirements are incorporated within the concept itself, pipe alignment structures and special tooling packages are eliminated.

SubSeaLink is a start up seeking for investment partner(s) to finance prototyping and commercialization. The solutions shown in this webside are at advanced stage of technical development and are patent protected

Products

TS-LINK (Topside)

A rugged connector eliminating offshore pipe flanging operations

Eliminates strength and fatigue limitations typical of API flanges, providing a connection stronger than the pipe
Eliminates dropped objects risk as no handling of bolts, seals and torque wrenches is required
Reliable metal to metal sealing system
Fast and safe riser assembly assisted by self-aligning of downfacing Pin end in to upfacing Box end
Fast actuation by means of hand carried torque tool
Ideal Topside Treecap solution, as std API Treecaps are not approved for CT intervention and shall be removed and eventually flanged back at every CT campaign.

CT-LINK (Topside)

A rugged connector allowing quick coupling of Coiled Tubing Injector Heads

Same tough mechanical design as the TS-LINK connector
Redundant elastomeric seal barrier
Eliminates flooding the riser at every CT run as the sealing system can be externally tested to full pressure rating
Easy stabbing and self alignement of the two mating ends
Fast actuation by hand carried torque tool
Eliminates risk of hydraulic failures, as the device is fully mechanical

WOR-LINK (Subsea)

A rugged subsea workover riser connector eliminating threads and make up spreads

Eliminates threads with associated risk of cracks and fatigue capacity limitations
Eliminates any proprietary riser make-up tools so reducing cost and deck space to absolute minimum
Metal to metal internal and external sealing
Minimum riser weight by using very high strength steel tubular material
Hub profiles directly machined to the pipe ends eliminating welding and fatigue issues
Easy integration to existing vessel elevators and gimbals enables fully automated riser installation

H-LINK (Subsea)

A rugged subsea flowline connector eliminating alignment structures and special tools

Stronger than the pipe
Built-in capability of recovering the pipe angular mis-aligment, by operating the connector itself
Eliminates heavy duty alignment structures and special tooling packages
Minimum weight and size, resulting from compact design and no adds-on
Metal to metal internal and external sealing
Operated by standard ROV carried Torque Tool
Easy integration of thermal insulation requirements
Retrievable to surface and re-installable subsea
Available also for vertical configuration (V-LINK)
Ideal solution for any flowline tie-in manifold. Subsealink has extended EPC experience and can supply PLET's, PLEM's, Riser Bases etc. optimized to Customer requirements.

FLEX-LINK (Subsea)

Designed to facilitate connection of high pressure hoses used for subsea interventions
Range: 2" to 4" ID / 10-15 K (can be upgraded)
full bore - through conduit, thus eliminating flow restrictions typical of hot stabs
Metal to metal internal and external sealing
Easy alignemnt, stabbing and locking by ROV
Seal assembly fitted to stabbing end (Pin) for easy replacement at a new deployment
Suitable for temporary as well as permanent use
Compact and robust
Custom pipe ends (flanged, BW, threaded etc.)
