Diving Services.
We offer specialist commercial divers for all marine jobs, duly equipped with hyperbaric dive chambers (underwater life support systems). We deploy the same structural and civil engineers to undertake inspections above and below the water line, ensuring that our diving teams are exclusively positioned to offer a comprehensive survey and evaluation of all types of maritime structures within the tidal zone. By gaining this knowledge first hand, we provide continuity from production of the survey report through to design of the new construction or repair, including underwater site supervision and inspection during any follow-up site work by a contractor. We believe this gives our clients a significant advantage over the traditional method of engaging multiple, separate suppliers to undertake underwater inspections and subsequent design.
We undertake inspections on a wide range of maritime assets. This includes harbours, ports, marinas, docks, dolphins and jetties, fendering systems, pipes and outfalls, tunnels, culverts, in-land navigation structures including locks, weirs and sluices, as well as dams and spillways, river and canal walls, and seabed and marine habitat surveys.
Technical Condition Inspections (Underwater Timeshift Inspections).
Timeshift inspection, also known as periodic inspection or recurring inspection, is crucial for asset management of underwater structures for several reasons, such as;
- They allow for the examination of system states at different points in time, facilitating the identification and troubleshooting of intermittent issues,
- They help in understanding the sequence of events leading up to a problem, enabling more accurate and effective root cause analysis,
- They enhance system reliability and performance by providing insights that drive preventive maintenance and optimizations,
- They enable detection of early signs of underwater asset degradation, thus facilitating repair and maintenance planning.
