Hydra-Lok™ Structural Connection Solutions

Swage Tool and Leveling ToolOil States Hydra-Lok™ pile swaging system is designed to make structural connections for offshore platform jackets to their driven pile foundations. The system can also be used to make structural connections in subsea drilling template, wellhead protection structure and manifold, tripod, monopile and wind turbine jacket applications.

This unique subsea connection technology is Lloyds Register and DNV approved and has since been certified by Bureau Veritas, American Bureau of Shipping (ABS) and the Russian Maritime Register of Shipping (RMRS).
