Wellhead Load Relief (WLR) System

Mitigate wellhead fatigue, reduce HSE risk and increase your available deck space with our Wellhead Load Relief system.

Oceaneering’s Wellhead Load Relief (WLR) system is a compact, high-capacity Blowout Preventer (BOP) tethering system suitable for template and seabed anchoring. By tethering a BOP to an existing structure on the seabed, the need for multiple sets of fixed length wire ropes is eliminated, significantly reducing rig time and costs dedicated to traditional tethering operations.

  • Reduce topside spreads by 100%
  • Reduce deployment time by 50%
  • Reduce crew size by 75%
  • Provides operational flexibility

A Flexible WLR Solution

Our WLR System consists of several winch units complete with wire rope, parking columns, and BOP clamps. The anchoring points can be located on the template structure, mud mats, or protection structure, depending on the existing infrastructure and type of well. The system is adaptable to different BOP designs. Our WLR system is designed and supported using:

  • Dynamic tether calculations
  • Detailed installation procedures
  • BOP clamps for tethers
  • Tensioning system (winches) with load monitoring
  • 24/7 operational support
  • Repair, maintenance, and storage of equipment

Increase Operational Flexibility

Our WLR system is ideal for shallow water operations where heavy BOPs are used. All WLR functions are ROV-operated, removing the need for topside tether preparations. The WLR system can adjust to any length of tethers subsea and adds the ability to wet store equipment.
