Spring-lok is a simple carbon steel diverless connector that self activates at target penetration. Although often used to join piles to structures the device may be used for any tube to tube connection to attach subsea structural elements, sub-assemblies or modules remotely.

The external indicator system provides a foolproof visual confirmation of engagement. The indicator plates are displaced outwards as the pile collar aligns with the springheads and on engagement they return flush with the sleeve. A secondary indication is provided with a simple red pile indicator appearing within the viewing hole.

This patented ‘pile and forget’ solution makes the connection instantaneously, requiring no secondary offshore tooling /operations or personnel. It is available in a complete range of API tubular sizes. Units have been fabricated from 14 to 42 inch diameter – delivering load capacities from 50 Te to 5000 Te.

If you are considering either standard piling applications or have a project specific functional requirement please contact us to discuss the range of options.
