摘要

Every offehore facility has a riser, but unfortunately not all facilities have real-time monitoring systems to confirm the integrity of that riser. The importance of riser monitoring is demonstrated by the existence of two industry standards: DNV-OS-F201 "Dynamic Risers" and API RP 16Q "Recommended Practice for Operational Inspection of Drilling Risers." In addition to providing much of the theory on which riser monitoring systems should be based, as with all standards, these documents tend to reflect the best practices offered by multiple experts in this area of work. The common challenges for offshore drilling and production that need to be managed via riser monitoring and associated management systems include: riser curvature, fatigue loading damage, and high tensions at the BOP and base. The causes of these challenges are a result of the environment in which offshore facilities operate. It is impossible to avoid the impact of wave action, tides, and temperature gradients, especially in deepwater installations as well as the pressures of the production system itself. All of these variables are classified into three types of loads on the system: 1. Pressure loads - external hydrostatic pressure and internal fluid pressure, both of which can easily be measured and are normally measured for process reasons. 2. Functional loads - which include the weight and buoyancy of riser, tubing, coatings, marine growth, anodes, buoyancy modules, contents, and attachments as well as the weight of the internal fluids. Again, these are loads that by and large are under the operator's control or can be managed with proper maintenance. 3. Environmental loads - predominantly waves including internal waves and other effects due to differences in water density and floater motions induced by wind, waves, and current.
