Service & Delivery
Data-driven maintenance.
We keep caissons safe, reliable, and fit for continued service while protecting our clients' production and safety records. By pinpointing deterioration early, our approach reduces unplanned downtime and failure rates, delivering measurable operational and cost benefits.
Caissons are essential to our clients' operations but remain highly susceptible to stress, fatigue, accelerated corrosion, and through-wall defects. To combat this, our experienced personnel deliver a structured, data-driven management programme tailored to specific assets and operating environments.
We manage the entire lifecycle in strict accordance with industry standards: Access, Clean, Inspect, Review, Engineer, and Repair. We begin by assessing a caisson’s structural integrity with proven non-destructive testing (NDT) techniques.
During the initial phases, every caisson receives a high-pressure internal clean followed by a detailed camera inspection to assess its condition. If we identify necessary repairs, we integrate them directly into the same programme to resolve issues rapidly and efficiently.
After completion, our clients receive comprehensive inspection and maintenance reports, along with high-resolution photographic and video documentation. We also provide evidence-based data sheets summarising critical metrics, including corrosion rates and wall thickness measurements.
These highly detailed reporting deliverables simplify regulatory compliance, support informed maintenance planning, and provide a robust record of caisson integrity over time.
