Available for download

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.

“A method to test new surface preparation techniques for preparing existing offshore structures for maintenance painting has been developed. A major international oil company (Shell) worked with a consulting engineer (Woodson Engineering LLC) and suppliers (HoldTight and Apache Industrial Services) to develop a way to pre-rust large test panels with salt water then remove the rust scale using combinations of dry abrasive power washing and waterjetting with and without flash rust inhibitor and determine how long the panels will remain suitable for coating in a marine offshore environment. Some of the test panels were sprayed with ASTM Sea Salt Water to simulate salt spray on an offshore structure. Three methods of measuring beginning and residual salt concentration were evaluated for consistency and the salt removal effectiveness of each surface preparation method of salt removal was determined.” Halina Wisniewski will be co-author of this paper. The NACE submittal system would not allow me to add her.

 Key words: Offshore structure, salt, waterjetting, paint, coating, inhibitor, cleaning additives, abrasive blast, power wash

Accelerated Offshore Coating Performance Testing

Product Number: 51317--9134-SG

Offshore is a very corrosive environment with a high corrosion rate. The offshore coating service life is relatively short and extremely expensive to apply maintenance coatings onsite.  A new accelerated coating corrosion test method is proposed.

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.
