§ Commander MARSDENasked the First Lord of the Admiralty in how many of His Majesty's ships oil separators have been fitted; and whether it is the intention of the Admiralty to fit oil separators in all new construction of oil-fired ships?
§ Sir V. WARRENDERNone of His Majesty's Ships is fitted with oil separators, nor is it the intention of the Admiralty to fit them in new ships. Experience has shown that there is no necessity to discharge appreciable amounts of oily refuse from His Majesty's Ships into the sea, since oil separating barges are available at the principal naval bases. Strict regulations forbid the discharge of any oily refuse overboard within 50 miles of any coast.
§ Commander MARSDENasked the First Lord of the Admiralty how much oil has been recovered from His Majesty's ships through oil separators in barges at Home ports during the past 12 months or some other convenient period?
§ Sir V. WARRENDERDuring the 12 months ending 30th June, 1935, approximately 36,000 tons of oily water were passed through oil separator barges at home ports and 750 tons of oil were recovered. The bulk of this oily water came from tankers, and not from warships.
