18、ating systems for tension leg platorms (TLPs), semi-submersible platorms, and floating production and storage offloading systems (FPSOs). 1.2 Six test methods-cathodic disbondment, seawater immersion resistance, dimensional stability, aging stability, edge retention, and thick-film cracking-are used
19、 to evaluate these coating systems. The facility owners shall specify the acceptance criteria according to their specific requirements. 1.3 The ballast water temperature in a TLP or semi- submersible platorm is normally below 25C (77F) and can be much higher in a FPSO, depending on crude oil tempera
20、tures. Therefore, FPSOs require one additional h owet cycling test. Section 2: Definitions Cathodic Disbondment: The destruction of adhesion between a coating and the coated sutface caused by products of a cathodic reaction. Coating System: The complete number and types of coats applied to a substra

46、160 pg of CI ion is required to make a 100- mg/m CI concentration. 5.4.3 0.5 mL of salt solution of 2.32-g/L CI ion concentration shall be used to cover each side of the steel panel. To make a 1 .O-L salt solution, 2.32 g of CI ion is required; therefore 3.82 g of sodium chloride (NaCI) is required.
47、 5.4.4 NaCI shall be placed in a 93 to 121C (200 to 250F) oven for at least 2 hours to remove any moisture. 5.4.5 The 3.82 g of dry NaCI shall be mixed thoroughly with 1 .O L of distilled or deionized water. 5.4.6 Using a syringe, 0.5 mL of the salt solution shall be drawn and poured on a steel pane
48、l preheated to 66 to 93C (150 to 200F). A glass rod shall be used to spread the salt solution over the sutface of the panel. Using warm panels allows the water to evaporate quickly. 5.5 Sutface Preparation by High-pressure Waterjetting for Maintenance Coating System Evaluation If high-pressure water
49、jetting is used for sutface preparation prior to application of maintenance coatings in the field, the steel panels used to make the test specimens shall be prepared in the same manner. All the test methods shall still be applicable. 5.6 Anchor Profile Anchor profile on all steel panels shall be as specified by the coating manufacturer. If not specified, the anchor profile shall be 40 to 75 pm (1.5 to 3.0 mil) as measured with a replica tape in accordance with NACE Standard RP0287.I Section 6: Coating Application 6.1 All coatings shall be well mixed with Part
