BOP tethering system

Our intelligently engineered PROten Tank revolutionises traditional BOP tethering systems by using much less steel. Our design not only reduces transport weight, but also minimises emissions and manufacturing costs.

Key features:

• A modular system that’s configurable to suit your projects unique requirements
• Can be operated with ROV Manipulator, removing the need for additional ROV tooling
• Can have single and dual tether lines
• A 360-degree fairlead tether angle ensures flexibility when working on multiple well centers
• Quayside installable ballast blocks – adjustable to match seabed conditions and tether line pull
• Lightweight and easily transportable – weighs less than 10Te once ballast blocks are removed
• Versatile tank shape allows anchor vessel deployment/recovery from the boat’s stern roller
• Can be recovered in any orientation, even upside down!

In some cases, detailed analysis can eliminate the need for subsea BOP tethering. However, situations like abandonment projects with aging subsea wellheads may require additional support. For example, on projects involving old 13 5/8^th first-generation wellheads from 1970, even modest vertical loads may be unsupportable. In such cases, a supportive structure, ranging from simple vertical frames to pin-piled structures, may be necessary to redirect loads away from the wellhead and into the seabed.
