10.3 Dry Lay-Up

10.3.1 The system shall be completely drained and free from all standing test water. Total drainage is an essential step in achieving dry lay-up. If total drainage cannot be verified by visual inspection or other reliable means (e .g. utilizing drains at all low points), dry lay-up shall not be considered .

10.3.2 The test system shall be dried to a dew point of -1°C (30°F) or less at all exit points by the most convenient method (e.g . methanol swab, blowing heated dry air or nitrogen through the test system or use of a vacuum) . The test system shall then be shut in for a period of not less than 12 hours to allow any remaining moisture to come to equilibrium with the dry air. Exit dew points shall then be measured again , and, if fou nd to be above _1°C, the drying procedure shall be repeated.

10.3.3 If dry air is used to achieve the specified dew point, it shall be replaced with either nitrogen or sweet hydrocarbon gas as a final step before shut-in.

10.3.4 When the required dew point is reached, the test system shall be shut-in and a positive pressure shall be maintained as per clauses 10.2.6 and 10.2.7 of this Standard during the lay-up period.

10.3.5 The dew point shall be measured after one week of shuting-in the test system. If the dew point is found to be more than _1°C (30°F) at the lay-up pressure, the system shall be dried again , and then a new wet lay-up shall be initiated.

10.4 Inert Gas Lay-Up

10.4.1 Upon completion of a successful final hydrostatic testing, the test water shall be displaced with an inert gas (nitrogen is preferred), until no test water drains out of the system. If total drainage cannot be verified by visual inspection or other reliable means (e.g., utilizing drains at all low points), inert gas lay-up shall not be considered .

Note that draining the bulk of test water out of the test system and attempting to replace the volume with an inert gas by either repeated re­pressurizing or sweeping shall not be considered as inert gas lay-up.

However, in the case of pipelines, sweeping with inert gas driven scraper pigs is considered acceptable , subject to compliance with KOC Engineering Specification 015-IH-1005.

DOC.NO. KOC-G-011 Page 23 of 33 REV. 1 l

10.4.2 When complete test water displacement by inert gas has been achieved , the test system shall be shut-in under positive pressure as per clauses 10.2.6 & 10.2.7 of this Standard, until the test system is ready for commissioning and start-up.
