AQUASHIM®

SOLVING STABILISATION & INTEGRITY CHALLENGES

 

Offshore environmental conditions create significant challenges for caissons and conductors, with lateral forces from repeated wave action result in lateral displacement, localised stresses and even resonance. Wear and failure of traditional shims allow excessive lateral displacement within the guide which over time leads to fatigue and impact damage, with potential fracture and loss.

 

Unchecked, extensive and costly remedial maintenance or complete replacement is often required. AquaTerra’s AquaShim® developed in association with OGTC, provides cost effective long term stabilisation, halting deterioration, reducing localised stresses and increasing lifespan.

BENEFITS & KEY FEATURES

 

AquaShim® extends the life of an asset and caisson or conductor by offering enhanced structural support in halting deterioration and minimising likelihood of failure, providing a maintenance-free and long lasting solution

 

  • Fully engineered, simple, safe, low cost and rapid installation – fully cured within 24 hours
  • Adaptable for all geometries, resulting in short lead times and minimal ad-hoc engineering
  • Requires no specialist transportation or on-site storage and installed by fully trained technicians
  • Up to 50% reduction in localised stresses induced by guide and significantly reduces noise and vibration
  • Low installation temperature, making year-round application possible
  • Adaptable to all guide types and sizes and suitable for both topside and subsea applications
  • Internal liner allows free vertical movement, whilst AquaShim® compound absorbs horizontal movement
  • No shrinkage of AquaShim® compound ensures perfect fit, every time
  • Supported by the OGTC
