into the sea after passing through the seijarator shall have an oil content of not 

 more than 100 parts per million. In considering the design of such equipment, the 

 Administration shall have regard to the specification set out in Part A of the 

 Recommendation annexed to Resolution A.233(VII) adopted by the Assembly 

 of the Organization. 



(5) An oil discharge monitoring [and control] s.vstem shall be of a design 

 approved by the Administration and shall be such as will ensure that the dis- 

 charge of oily mixture is automatically stopped when the discharged mixture 

 contains 100 parts per million or more of oil. In considering the design of the oil 

 content meter that is to be incorporated into the design of such a system the 

 Administration shall have regard to the specification set out in Part B of the 

 Recommendation annexed to Resolution A.233(VII) adopted by the Assembly of 

 the Organization. [The meter shall be fitted with a recording device to provide 

 a permanent record of the oil content of the discharge.] 



REGULATION 17. — TANKS FOR OIL RESIDES (SLUDGE) 



Every ship of [400] tons gross tonnage and above *^ shall be provided with 

 tank or tanks of adequate capacity, having regard to the type of machinery aiul 

 length of voyage, to receive the only residues (sludges) resulting from the purifica- 

 tion of fuel and lubricating oils and oil leakages in the machinery spaces. For all 

 new ships, and insofar as is reasonable and practicable, for all existing ships, 

 such tanks shall be designed and constructed so as to facilitate their cleaning and 

 discharge of residues to reception facilities. 



REGULATION IS. — PUMPING AND PIPING ARRANGEMENTS OF Oil. TANKERS FOR THE 

 DISCHARGE TO RECEPTION FACILITIES OR TO THE SEA 



(1) In every oil tanker, pijjelines for the discharge of dirty water ballast 

 and/or oil contaminated water to shore or floating reception facilities shall be 

 led to the open deck on both sides of the ship. 



(2) In every oil tanker, pipelines for the discharge to the sea of effluent which 

 may be permitted under Regulation of this Annex .shall be led to the open deck 

 or to the ship's side above the waterline in the heaviest ballast condition. 



(3) In [new] " oil tankers remote control of the pumps for discharge pipes 

 referred to in paragraphs (1) and (2) of this Regulation shall be provided at a 

 position where the discharge pipes are under visual supervision. 



REGULATION 19. — STANDARD SHORE CONNECTION 



To enable pipes of shore reception facilities to be cftnnected with the ship's 

 pipe discharge line for residues from machinery bilges, both lines shall be 

 fitted witli a standard shore connection in accordance with the following table : 



Standard dimensions of flanges for discharge pipes 



Description Dimension 



Out.side diameter 215 mm 



Inner diameter According to pipe outside diameter 



Bolt circle diameter 183 mm 



Slots in flange holes 22 mm in diameter equidis- 



tantly placed on a bolt circle of the 

 above diameter, slotted to the flange 

 periphery. The slot width to be 

 • 22 mm 



Flange thickness 20 mm 



Bolts and nuts: quantity, diameter 6, each of 20 mm in diameter and of 



suitable legnth 



(The flange is designed to accept pipes up to a maximum internal diameter 

 of 125 mm and shall be of steel or other equivalent material having a flat face. 

 This flange, together with a gasket of oilproof material, shall be suitable for 

 a service pressure of 6 kg/cm'. ) 



" Some delegations suggested the use of horsepower of the propelling machinerv in lieu 

 of gross tonnage. 



*" Some delegations considered that this requirement should apply to new and existing 

 ships.
