Project Description

IK Subsea secured a contract to provide two Caisson securing clamps, utilizing a standard split clamp fastened around the caisson. These securing clamps play a critical role in preventing the caisson from descending into the seabed in the event of separation above the lower caisson support and below sea level.

The primary securing clamp was positioned above the lower support guide on the caisson, while an additional clamp was installed below the lower support guide, securing the lower section of the caisson. To create a unified system for securing the entire structure without complex subsea operations, the bottom clamp was linked to the top clamp with two lines.

The upper clamp underwent hydraulic closure around the caisson, subsequently lowered onto the top of the guide support, torqued with a single setting bolt, and firmly fixed to the caisson. Meanwhile, the lower clamp was hydraulically closed around the caisson beneath the lower support guide. Installation was carried out by ROVs with the assistance of removable buoyancies, streamlining the process.
