The Houston Ship Channel is a modern engineering feat. Brackish water. Chloride induced corrosion. Subsidence. Change in water levels and exposure conditions. These issues are explored in this paper reviewing methodologies and results of service life modeling from a recent multi-structure assessment by the authors.
The aim of this test program is to provide technical data to support the replacement of austenitic flexible pipe carcass, at Campos Basin, by low cost materials with suitable mechanical properties and corrosion resistance when the field conditions turn too aggressive to carcass materials in operation.
This paper presents failures of the internal coating of drill pipe riser (DPR) systems that operated for 8 months in extended well testing (EWT) in Brazilian pre-salt fields at 1900-m sea depth. After two different EWT operations, blisters were seen through the internal coating of tubes that had been in service.
A method to test new surface preparation techniques for preparing existing offshore structures for maintenance painting has been developed. This paper will explain how the tests were conducted, how effective each method was at removing salts, and how the coatings performed in the ISO and NASA tests.
An experimental protocol including in situ potentiostat and quasi-static tensile tests to provide an improved understanding of the corrosion behavior of UNS G10210 steel. A local-global finite element method has been proposed to model a steel plate at a ship compartment scale under uniaxial quasi-static tensile/compressive loading.
