Review of monitoring, inspection and maintenance of structural components in 900 meters of water
Monitoring, inspection and maintenance of offshore structures is undertaken to satisfy owners stringent operational requirements, together with the requirements of government regulations, Certifying Authorities and insurance underwriters. The immense costs of offshore inspection and maintenance work has resulted in a growing need for engineers to consider these problems much earlier in the design stages than previously thought necessary and to be aware of future subsea tasks which may need to be performed during the life of an installation. This is particularly so for platforms going beyond the range of divers and those using new structural systems. The paper reviews the requirements for critical components of a compliant tower, a Deep draught Semi-submersible and a SPAR platform in 900 m of water. The assessment is based on the following top down process: (1) identify the structural components of the structure; (2) for each component identify failure or degradation mechanisms; (3) for each failure or degradation mechanism identify the monitoring, inspection and maintenance requirements; (4) for each requirement review available techniques and equipment, identify feasibility in 900 m or advances that are required before feasibility is proved. A simple tabular form enables easy interpretation of the results.
