Finite-element (FE) analysis, as presented in the recently completed Safebuck joint industry project's (JIP) design guideline, can help control buckling of subsea pipelines. The report presents measures for the selection of an optimum configuration for production pipelines for a high-pressure, high-temperature (HPHT) deepwater development. A number of proprietary and generic pipe-in-pipe systems have been developed and deployed, each with its own parameters of thermal performance, required sleeve-pipe diameter, connectivity of inner to sleeve pipe, structural response, welding requirements, installation, cost, and track record. In detail, the influences of a suited selection of materials, pressure containment, external pressure issues, thermal mitigation, limit states, subsea cooling, installation, and pipeline walking have been discussed.
