Claxton has vast experience in accommodating client specific requirements for the design and supply of protective structures. We can provide either an overtrawlable structure or a simple protective shield for dropped objects, all of which are fully NORSOK compliant.

Subsea assets such as wellheads, Xmas trees and manifolds often need protection from harsh environments and offshore maritime activity. Claxton provides a flexible range of structures which are designed in-house to NORSOK standard U-001/ISO 13628-1, or any required local standard, and benefit from the extensive structural expertise of our design and project engineering teams.

Our subsea protective structures can be installed either by the client’s own team or by Claxton’s experienced offshore technicians and are deployable from either a drilling rig or vessel. We can assist with and seek verification from the local authorities or fishing and trawling experts where required, to streamline the installation process.

The overtrawlable variety are snag-free structures which protect against dropped objects, marine environment or maritime damage and are fully overtrawlable throughout the lifecycle of an offshore asset.

our expert view

“Claxton’s experience and bespoke methodology for installing protective structures is much more efficient and cost-effective than conventional methods. The secret to our success in this field is to provide a co-ordinated approach to the many interrelated engineering and operational processes of the pre-drilling concept.”
