The High Pressure High Temperature (HPHT) anticipated in GoM and other deepwater fields is pushing the oil and gas industry towards the fracture-mechanics-based design of subsea equipment. The new safe-operation requirements necessitate the development of design data on subsea materials in various environments of interest. However, current approaches to developing the desired data are time-consuming and expensive.
DNV GL is proposing a methodology for the rapid characterization of materials for HPHT applications.
The new methodology provides significant cost savings and schedule improvements for subsea projects.
A single test using the proposed methodology will give design data at a cost of approximately USD 9,000 in 4 weeks. The same data using the conventional methodology will cost approximately USD 25,000 and require more resources in terms of number of frame capacity and time.
