MARPOL Consolidated Edition, 2017 (IE520E)

Its technical content is laid out in six Annexes, the first five of which were adopted by the 1973 Convention, as modified by a 1978 Protocol. These Annexes cover pollution of the sea by oil, by noxious liquid substances in bulk, by harmful substances in packaged form, by sewage from ships, and by garbage from ships. Annex VI was adopted by a further Protocol in 1997 and covers air pollution from ships. The 2017 consolidated edition aims to provide an easy and comprehensive reference to the up-to-date provisions and Unified Interpretations of the Articles, Protocols and Annexes of the MARPOL Convention, including the incorporation of all the amendments that have been adopted by the Marine Environment Protection Committee (MEPC).

to 2 November 1973 Protocol I (Provisions concerning reports on incidents involvingHarmful Substances) and Protocol II (Arbitration) were adopted at the sameConference This Convention was subsequently modified by the Protocol of 1978relating thereto, which was adopted by the International Conference on TankerSafety and Pollution Prevention (TSPP Conference) convened by IMO from 6 to 17February 1978 The Convention, as modified by the 1978 Protocol, is known as the

"International Convention for the Prevention of Pollution from Ships, 1973, asmodified by the Protocol of 1978 relating thereto", or, in short form, "MARPOL73/78" Regulations covering the various sources of ship-generated pollution arecontained in the five Annexes of the Convention The Convention has also beenmodified by the Protocol of 1997, whereby a sixth Annex was added It may benoted that the Marine Environment Protection Committee (MEPC), at its fifty-sixthsession, decided that, when referring to the Convention and its six Annexes as awhole, the term "MARPOL" should be preferred to "MARPOL 73/78", as the latterwould leave Annex VI on Prevention of air pollution from ships, which had beenadopted by the 1997 Protocol, outside its scope

The MEPC, since its inception in 1974, has reviewed various provisions of theMARPOL Convention that have been found to require clarification or have given rise

to difficulties in implementation In order to resolve such ambiguities and difficulties

in a uniform manner, the MEPC agreed that it was desirable to develop unifiedinterpretations In certain cases, the MEPC recognized that there was a need toamend existing regulations or to introduce new regulations with the aim of reducingeven further operational and accidental pollution from ships These activities by the

Trang 2

MEPC have resulted in a number of unified interpretations and amendments to theConvention.

The purpose of this publication is to provide an easy reference to the up-to-dateprovisions and unified interpretations of the articles, protocols and Annexes of theMARPOL Convention, including the incorporation of all amendments in force on 1September 2017

12Instantaneous rate of discharge of oil content means the rate of discharge of oil inlitres per hour at any instant divided by the speed of the ship in knots at the sameinstant

13Tank means an enclosed space which is formed by the permanent structure of aship and which is designed for the carriage of liquid in bulk

14Wing tank means any tank adjacent to the side shell plating

15Centre tank means any tank inboard of a longitudinal bulkhead

16Slop tank means a tank specifically designated for the collection of tankdrainings, tank washings and other oily mixtures

17Clean ballast means the ballast in a tank which, since oil was last carried therein,has been so cleaned that effluent therefrom if it were discharged from a ship which

is stationary into clean calm water on a clear day would not produce visible traces

of oil on the surface of the water or on adjoining shorelines or cause a sludge oremulsion to be deposited beneath the surface of the water or upon adjoiningshorelines If the ballast is discharged through an oil discharge monitoring andcontrol system approved by the Administration, evidence based on such a system tothe effect that the oil content of the effluent did not exceed 15 ppm shall bedeterminative that the ballast was clean, notwithstanding the presence of visibletraces

18Segregated ballast means the ballast water introduced into a tank which iscompletely separated from the cargo oil and oil fuel system and which ispermanently allocated to the carriage of ballast or to the carriage of ballast orcargoes other than oil or noxious liquid substances as variously defined in theAnnexes of the present Convention.

19Length (L) means 96% of the total length on a waterline at 85% of the leastmoulded depth measured from the top of the keel, or the length from the foreside ofthe stem to the axis of the rudder stock on that waterline, if that be greater In shipsdesigned with a rake of keel the waterline on which this length is measured shall beparallel to the designed waterline The length (L) shall be measured in metres

20Forward and after perpendiculars shall be taken at the forward and after ends ofthe length (L) The forward perpendicular shall coincide with the foreside of thestem on the waterline on which the length is measured

21Amidships is at the middle of the length (L)
