5、tion world-wide during the last thirty years. It builds on earlier editions, firstpublished in 1972 and revised in 1980 and 1988, and provides a clear andconcise overview of the present level of knowledge, expertise and under-standing in the field of oil spill response.It covers the behaviour and fa

Guidance is given on aerialsurveillance, the at-sea measures of containment and recovery and the useof chemical dispersants, and a new chapter has been included on in situburning. Shoreline clean-up strategies

7、and techniques, and waste manage-ment and disposal are described, and a new chapter has been added onbioremediation measures. In view of the growing awareness of thedifficulties inherent in dealing with spills of heavy fuel oil and emulsifiedfuels, a new, separate chapter has been devoted to the cur

Guidance is provided ontraining, exercises and equipment maintenance and storage, and informa-tion is also given on liability, compensation and cost accounting.In 1990 the International Convention on Oil Pollution, Preparedness,Response and

9、 Co-operation was adopted by IMO. This Convention calls onContracting States, amongst other things, to co-operate and to exchangeinformation on matters related to response to oil pollution incidents. Thissection of the Manual provides useful information with regard to thepreparation of national and/

10、or regional systems for preparedness andresponse. The information is intended for Governments, particularly thoseof developing countries, and industry, on the most appropriate means ofdealing with marine oil spills. The information is intended for Govern-ments, particularly those of developing count

12、(MEPC) of IMO. The MEPC wishes to express its appreciation tothe many experts who assisted in the preparation of the text and whocontributed photographs, illustrations and reference data, making thispublication available in its present form.ivManual on Oil Pollution IV: Combating Oil SpillsContentsP

Thisimprovement in performance is demonstrated in the statistics ofaccidental oil spills world-wide from tankers, combined carriers andbarges (figure 1-1).02,0004,0006,0008,00010,00012,0001974 1976 19

27、of spills 47 tonnesand world seaborne oil trade: 19742001 (Source: ITOPF)The incidence of accidental spills greater than 7 tonnes (50 barrels) hasdecreased substantially since 1974. As a result, the number of spills in1999 was less than one quarter of the number in 1974. The number ofspills has rema

28、ined low in recent years despite an upturn in seaborne oiltrade, which is now approaching the high levels of the mid 1970s .1A significant number of accidental tanker spills less than 7 tonnes(50 barrels) occur during loading and discharging operations (35%)(figure 1-2). For spills between 7 and 700

29、 tonnes (505,000 barrels),loading and discharging operations still remain a significant cause (29%),along with collisions (22%) and groundings (19%). However, for spillsgreater than 700 tonnes (5,000 barrels) the major causes are collisions(28%) and groundings (34%).MARPOL 73/78 has now been ratifie

30、d by most member countries of IMO.Besides limiting the overall amount of oil entering the sea, MARPOL 73/78requires that any discharges of oil are made in accordance with strictoperational procedures such that the oil does not form a persistent slickrequiring any cleanup response. In addition to ope

31、rational issues,MARPOL 73/78 also provides a framework for the design and constructionof oil tankers, which should contribute significantly to further reductionsin the occurrence of oil spills in the future.36286720155022428318347 7132172815120510152025303540ContributionofeachCause(%)Loading /Discha

They can have a serious impact on coastal activities andtho

35、se who use or benefit from the resources of the sea. In most cases, suchdamage is temporary and caused primarily by the physical properties of oilcreating a nuisance and hazardous conditions. However in somesituations many years may be required for recovery to take place and onrare occasions, the da

36、mage may be irreparable. The impact on marine lifeis compounded by toxicity and tainting effects resulting from chemicalcomposition of the oil, as well as by the diversity and variability ofbiological systems and their sensitivity to oil pollution. However damage tothe environment can be minimized i

37、f correct counter measures are takenpromptly.This section of the Manual on Oil Pollution is intended to provide anoverview of the practical response measures that are available to deal withsuch oil spills. During the time since first publication in the 1970s, therehave been a number of developments,

38、 particularly with regard to oilcontainment booms and recovery techniques, oil dispersant chemicals,bioremediation, in situ burning, waste management and disposal. Thevariety of different types of oil being transported around the world has alsoincreased and more recently there has been a growing rec

39、ognition of theparticular difficulties posed by spills of heavy oils such as ships bunkers.While this section of the Manual has been generally developed to deal withship source spills, many of the issues and features presented can also beapplied to oil spills from other marine sources such as offsho

40、reinstallations.As with previous editions, this revised Manual on Oil Pollution is not anexhaustive treatment of the subject of marine oil spill response. Rather, itspurpose is to provide a clear and concise overview of the response optionsavailable, their main features and the key issues involved.

41、This will assistthose persons in Government and industry charged with the response tomarine oil spills, in the selection of the most appropriate cleanupmeasures for a particular situation.

42、ation and reference.Chapter 1 Introduction3Chapter 2Types of oil2.1 Crude oilsCrude oils are complex mixtures of hydrocarbons of varying molecularweight and structure comprising the three main chemical groups:paraffinic, naphthenic and aromatic. These hydrocarbons range fromsimple, highly volatile s

43、ubstances to complex waxes and asphalticcompounds which cannot be distilled. Oxygen, nitrogen, sulphur, vana-dium, nickel, mineral salts, etc. may be present in various combinations.The characteristics of most crude oils fall within the following ranges:Table 2-1 Range of characteristics of crude oi

45、t. up to 5Vanadium, ppm V 5 to 170The names of crude oils are often associated with or have been derivedfrom their geographical source, e.g. Alaska North Slope Crude. Each crudeoil has unique physical and chemical properties and these can vary bothbetween oils from the same area and between differen

46、t regions of theworld. Their physical properties and how they behave when spilled,together with their chemical properties, which determine their toxicity, areimportant factors influencing the oil spill response and the effect they canhave on various marine resources.Lighter, more volatile crude oils

47、 tend to be highly fluid and spread rapidly,have a strong odour, a high evaporation rate and are usually flammable.They penetrate porous substrates, but do not tend to adhere to hardsurfaces. They may be highly toxic to humans, fish and other biota.Heavier, less volatile crude oils have a variety of

48、 characteristics dependingon their specific properties; these are described in more detail in chapter 3.They are fluid to varying degrees, have a range of evaporation rates andmay be flammable. As temperature increases, their tendency to penetrateporous substrates can increase, but the more viscous

49、and sticky crude oilsdo not penetrate readily. They adhere to hard surfaces but may be removed5using a variety of techniques; described in chapter 9. With lower volatility,toxicity is also lower, but some biota can be affected by physicalsmothering. Some of the heavier crude oils are solid at ambient temper-atures and they are relatively non-toxic and do not penetrate poroussurfaces. When heated they may melt and form a coating on hard surfaces,which can sometimes be difficult to remove.2.2 Petroleum productsThe products derived from refining crude oils have chemical and ph
