HOUSTON, Oct. 23 -- Petrobras R&D Center, along with two Rio de Janeiro universities, is proposing a joint industry project that will investigate the failure behavior of multiple interacting corrosion defects in pipelines in order to improve the prediction of failure pressure of pipelines containing interacting corrosion defects.
The proposed Mixed Type of Interaction Joint Industry Project (MTI JIP) is expected to begin in April 2007 and take 36 months to complete.
It will be carried out in two phases at an overall cost of $488,600.
The main objectives of the MTI JIP are to:
-- Generate a database of burst test results containing 15-34 tests.
-- Implement the MTI method developed by Petrobras into a computer program.
-- Validate the MTI method.
-- Compare the failure pressures contained in the database with those predicted by seven of the currently available assessment methods.
