The solution to splashzone stabilisation and integrity challenges.
Significant lateral forces from repeated wave action create unique challenges for caissons and conductors; movement within the guide frame over time leads to impact damage, potential fracture and eventual loss.

Traditionally engineered mechanical shims and centralisers can be costly and may only provide a short-term solution before repair or replacement is necessary.

Developed with the Net Zero Technology Centre (formally known as the OGTC), AquaShim® is a polyurethane- based alternative which is quick and simple to install and requires zero lifetime maintenance.

Providing low cost, long term stabilisation for caissons and conductors, AquaShim® halts deterioration and localised stresses, reduces vibration and noise and ultimately extends asset lifecycle.

  • More design flexibility over alternative shimming solutions
Case Study
As is well known throughout the offshore energy industry, the conductor plays a vital role in providing an environmental covering to protect internal wells from wave and current force but also as structural support for the topside of a rig with its connection to the guide frame it sits within...
