1 Unless expressly provided otherwise, this part
applies to chemical tankers constructed on or after 1 July 1986 including
those of less than 500 gross tonnage. Such tankers shall comply with
the requirements of this part in addition to any other applicable
requirements of the present regulations.
2 Any chemical tanker, irrespective of the date
of construction, which undergoes repairs, alterations, modifications
and outfitting related thereto shall continue to comply with at least
the requirements previously applicable to the ship. Such a ship, if
constructed before 1 July 1986, shall, as a rule, comply with the
requirements for a ship constructed on or after that date to at least
the same extent as before undergoing such repairs, alterations, modifications
or outfitting. Repairs, alterations and modifications of a major character,
and outfitting related thereto, shall meet the requirements for a
ship constructed on or after 1 July 1986 in so far as the Administration
deems reasonable and practicable.
3 A ship, irrespective of the date of construction,
which is converted to a chemical tanker shall be treated as a chemical
tanker constructed on the date on which such conversion commenced.
