Our complete caisson management solution ensures the structural integrity of your caissons.
Caissons are essential to an offshore asset’s operations without them, it is impossible to guarantee fire-water to the topsides. However, hanging half above water and half in the water, they are exposed to the elements.
Stress, fatigue, increased corrosion, failure through cracking and through wall defects are real threats. This can result in costly shutdowns or high risk, dropped-object issues.
Our teams can provide a complete caisson management solution, which starts off with a thorough assessment and inspection to prioritize what needs to be done when. Should repair be required, we are ready to do that as well.
For both the inspection and the repair work, we make use of unique robots that work on the inside of the caisson, making them ready to apply irrespective of weather conditions and without the need for divers or ROVs.
Our experts can:
Assess the caissons’ history and remaining life expectations, and identify possible areas of concern.
Prioritize possible actions.
Recommend an implementation plan of what should be done, when, and where.
Making use of our weather-independent robot solution for internal inspection of caissons, we:
Do an initial camera inspection.
Apply high-pressure cleaning where needed.
Perform additional camera surveys of affected areas.
Perform ultrasonic thickness measurements.
Provide testing reports with recommendations.
If required, we can insert a liner into the caisson and swage that is placed above and below the affected areas. In this way the liner will take over the strength of the wall, reinstating the structural integrity of the caisson.
Each project is executed by a multidisciplined team, led by an experienced project manager and working with our state-of-the-art swaging tool.
