Internal and external lifting tools used to prevent dropped object threat from damaged caissons
Caissons are used in a variety of applications on offshore production platforms and vessels. Common uses for caissons are firewater and seawater lift, drain as well as I-Tube and J-Tube applications. Due to platform life extension, caissons have often been in place longer than planned, and deterioration and failure of caissons is a growing trend in the North Sea and worldwide. This deterioration and failure may present a dropped object risk to subsea structural and piping systems. Should a caisson become detached this would pose a serious safety concern for a platform and risk damage to subsea pipelines and equipment, impacting on production and reputation.
STATS provide a range of caisson handling tools for safely securing and recovering damaged or redundant caissons. Internal and External Lifting Tools (ILT / ELT) cover a range of sizes and safe working loads to allow for safe and controlled caisson removal.
Internal and External Lifting Tools are used to safely secure damaged or corroded caissons in position, until a planned retrieval back to the platform can be performed using the same tool. The compact size of the ELT and modular design of the ILT allows caissons to be recovered where space is limited. Caissons can then be securely lifted and cut into manageable sections to allow safe removal from the platform.
Join this webinar to find out more about STATS mechanical lifting tools for safe handling and operation during caisson removal without the need to shutdown production. The webinar will conclude with recent case studies where lifting tools have been used in the UKCS to facilitate the removal of caissons.
