Painting Practices for Floating, Storage and Offloading Systems

Painting Practices for Floating, Storage and Offloading Systems
Available for download

Floating production storage offloading (FPSO) system hulls physically resemble ocean going transport vessels but operate more like fixed offshore structures. FPSOs normally are moored in deep water and are connected to unique riser systems. As these production systems are typically designed for long life, 20 to 30 years, corrosion control of the hull is extremely critical to help assure the required performance is obtained.

Floating production storage offloading (FPSO) system hulls physically resemble ocean going transport vessels but operate more like fixed offshore structures. FPSOs normally are moored in deep water and are connected to unique riser systems. As these production systems are typically designed for long life, 20 to 30 years, corrosion control of the hull is extremely critical to help assure the required performance is obtained. An FPSO can be a new build or a converted tanker. In either case, the requirement for a robust high performance corrosion control design is essential to help assure the design life is achieved in a safe reliable manner. The corrosion control design for the hull includes the use of coatings in conjunction with a cathodic protection system. The type of cathodic protection system used for an FPSO hull can be either an impressed current type or by galvanic (or sacrificial) anodes. However, normally galvanic anodes are utilized. For the topsides, coatings are the primary defense against corrosion. Selection of the appropriate coating coupled with a well-defined inspection program is necessary to achieve the required performance. This paper will cover the numerous types of coatings used and address details of a well-developed inspection plan.

Painting Water Storage Tanks In-Service: An update

Until a few years ago, water tanks were always drained before exterior surfaces were painted because surface moisture, if found below the water line, would lead to a coating failure. But a coating technology borrowed from the bridge and highway industry and put to a new use is bringing changes to the water tank marketplace. This presentation introduces the original project, includes the coating evaluation after 6 years, and concludes with additional tank examples.

Duplex systems, also known as painting over hot dip galvanized steel, are extremely effective corrosion protection systems. However, careful surface preparation techniques need to be used to alleviate potential coating failures. The age and characteristics of the galvanized coating should be used to determine what type of surface preparation is needed.

A bridge coatings specification can be a complex and sometimes confusing document to navigate through. Yet it is regarded as the rulebook for quality control and quality assurance personnel responsible for inspecting the quality of work. An inspection plan is a tool that can make the process of understanding the inspection checkpoints invoked by a bridge coating specification more streamlined and can be a key communication tool for contractor and inspection personnel.
