CSUB™ Wellhead Protection Structure

CSUB has developed a new GRP Single Well Protection Structure combining requirement for overtrawlability design with the need for full ROV access to the Wellhead.

CSUB patented in-house design has been developed as an alternative to the traditional steel protection structure. The structure has features such as:

  • Self penetrating skirts for stabilization – skirt height approx 1.5m depending on soil conditions
  • Large openings on every side for good ROV access
  • Top hatches providing access for well operations
  • Removable bridge design allowing for spool installation post protection structure installation

 

The new GRP Single Well Protection Structure has the following advantages compared to a traditional steel design.

  • Cheaper to manufacture
  • Less deck space required
  • Crane limitations are less restrictive – wrt: hook height, crane radius, SWL etc.
  • Doesn’t require large suction cans – thus avoiding potential pile refusal during penetration
  • Quicker installation – no need to wait on soil penetration of cans
  • Easier to recover to deck if required
