Flow Assurance and Operability Design Stages

The degree of Flow Assurance and Operability detail required depends upon the stage of engineering that the design process is in. In early stages of the design process, relatively little of the system input will be finalized. The amount of detail in the models and the conclusions drawn from them will be relatively cursory. The cross effects of reservoir pressure and temperature, tubing diameter and insulation, flowline diameter and insulation, the number of flowlines, flowline routing, holdup, and platform arrival temperatures and pressures will be evaluated. A large number of models may be run in a short period of time to bracket the solution boundaries.

A major effort early in the design process will be to establish the design basis. All aspects of the system, such as fluid characteristics, reservoir behavior, site characteristics, and host facilities should be reflected in the design basis. The design basis should include sufficient conservatism to offset poor or missing data. INTECSEA has the experience to help avoid unnecessary conservatism.

As the design progresses, the attention paid to detail will increase. The “trick” is to use INTECSEA knowledge and experience to analyze, as thoroughly as needed, and to develop the design but to not unnecessarily spend resources on detailed analyses that will have to be redone at a later stage after definitive data is available.

As the design of the system moves into the detailed design and fabrication stages, the flow assurance effort is likely to shift toward more detailed analyses to support operating procedure development and hardware and facilities designs and evaluations. At the same time, systems engineers will assure that system design changes that might affect flow assurance and operability provisions are thoroughly evaluated in the flow assurance context.

System economics and risk management are over-riding considerations in the design process and are continuously evaluated.
