3.6.4 Requirements

a. Prior to drydocking the ship, prepare a Liquid Transfer/Removal Plan outlining a comprehensive procedure for transfer and removal of all liquids in the tanks to be inspected. Included shall be the quantities and location of liquids to be transferred between tanks and the quantities and location of liquids to be removed, stored, disposed of and returned. If transfer of liquids while the ship is drydocked is planned, the dockmaster shall approve the Plan. A copy of the Plan shall be submitted to the COR at least 3 work days prior to drydocking the ship.

b. Open, ventilate, and clean the ballast tanks specified in Table 306-1 safe for entry of workers. Post a gas-free certificate, issued by a Marine Chemist certified by the National Fire Protection Association, at the brow. Provide a copy of each gas-free certificate to the COR.

23 | P a g e

d. High pressure water wash tanks including sides, overhead, bottom and all internals to remove slime and light scale. Light scraping may be necessary but take care not to damage coatings. Pump out, remove, and properly dispose of all residual water and debris.

e. Rig sufficient lighting in each opened tank to allow a thorough inspection.

f. After all tanks have been inspected by the ABS Surveyor and when accepted by the COR, close each opened tank using new gaskets. Renew all missing and broken fasteners and chase all manhole cover threads. Estimate 10% missing or broken fasteners. Notify the COR at least four hours in advance of closing each tank. Immediately prior to closing each tank, the COR or a member of the ship's engineering force will inspect the tanks interior to verify that rags or other residual debris has not been left.

g. Refill ballast tanks with municipal water and carefully top off the tanks. Some of the ballast tanks have common vents. DO NOT OVERFILL TANKS.

3.6.5 Quality Assurance

a. Perform a 2.0 psig air test on each tank after closing. Hold the pressure and check manhole covers for leaks using a soapy water solution.

b. During the filling process, recheck manhole covers and vents for leaks.
