Rapid characterization of materials performance for HPHT applications

Challenge

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.

Solution

DNV GL is proposing a methodology for the rapid characterization of materials for HPHT applications.

Benefits

The new methodology provides significant cost savings and schedule improvements for subsea projects. 

Value

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.
