Hydra-Lok™ Pile Connection Systems

Swage Tool and Leveling ToolOil States’ Hydra-Lok™ pile swaging system is designed to make structural connections for offshore platform jackets to their driven foundation piles. 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 Hydra-Lok pile swaging technology is Lloyds Register and DNV approved, and it has since been certified by Bureau Veritas, American Bureau of Shipping (ABS) and the Russian Maritime Register of Shipping (RMRS).
