For deck barges that stow containers perpendicular to the centerline,\nwhich defines a \"container space\" as distance of not less than 6 m (20 feet, fore and aft or\nnot less than 2.5 m (8 feet) athwartship.\nAl.\nThe answer is yes. Although the definition of \"container space\" in § 176.83(f)(4) is\nbased on the dimensions of a typical 20 foot container when in parallel with the keel, the\ndefinition is a distance, 6 m (20 feet) fore and aft or not less than 2.5 m (8 eet)\nathwartship.\nQ2. Can the definition of \"container space\" change to 2.5 m (8 feet) fore and aft when the\ncontainers are stowed on deck perpendicular to the centerline?\nA2. The answer is no, the definition does not change when containers are stowed on deck\nprocedures at the discretion of the Captain of the Port (COTP), who must determine if the\nperpendicular to the centerline. However, § 176.65 does allow for alternat ve stowage\nalternative stowage procedures will insure a level of safety at least equal to that afforded\nby regulatory requirement concerned.\nQ3.\nWhat method is used by the COTP to \"insure a level of safety at least equal to that\nafforded by regulatory requirement concerned?\"\n176.83\n176.65\n070010\n\n<<<PAGE 2>>>\n\nThe COTP has the discretion to use any method when allowing an alternative stowage\nto prevent a fire from spreading to other containers, if such an event occurs.\nprocedure.
