MARPOL Annex II Regulations for the Control of Pollution by Liquid Noxious Substances in Bulk a prologue to the carriage of chemicals adrift Tim Wilkins Regional Manager Asia-Pacific Environmental Manager Image cordiality of Stolt Tankers

Overview: the carriage of chemicals adrift Market examination Chemical tanker industry An outline of MARPOL Annex II Pollution Categorization Ship Types Operational prerequisites

1. Outline Chemical transportation actually and strategically not quite the same as oil transportation Cargoes broad range from toxic or perilous chemicals to eatable oils and fats each compound freight conveyed requires watchful thought amid the arranging procedure and stacking relative temperature affectability semi-gasses conceivable should be restrained relative affectability to water potential to respond with each other

1. Diagram Chemical transportation actually and strategically not the same as oil transportation Ships 50 or more tanks means unpredictable and propelled development tank development sort for regulation pumping prerequisites tank covering similarity venting necessities gaging gear vapor discovery fire assurance medium 50 or more tanks means perplexing and propelled operation cross similarity with different cargoes conveyed warming necessities ecological controls if required e.g. inerting restraint necessities thickness impediments of the item in connection to the payload tank development

1. Diagram: showcase investigation The vegetable oil exchange speaks to near 50 million tons palm oil exchange 60% soybean oil around 20% sunflower seed 7% palm bit oil, shelled nut oil, olive oil, cottonseed oil and coconut oil speak to the staying 23%

1. Outline: advertise investigation World fare of significant veg oils – oil sorts

1. Diagram: advertise investigation World fare of real veg oils – send out nations Veg oil trades every year Indonesia 30% Malaysia 30% Argentina 15% Brazil 5%

1. Review: showcase investigation World import of significant veg oils The greatest bringing in ranges are: Europe (9 m tons) China (7.5 m tons) India (6 m tons)

1. Outline: advertise investigation Chinese Vegetable Oil Consumption Continues to Grow 7 years of development in China's vegetable oil utilization 9.5 kg for every individual every year in 1999/00 17.1 kg in 2006/07 (gauge) If China's per capita oil utilization were to achieve that of the Taiwan, China would devour 52% more vegetable oil, or 35 million tons in 2006/07 rather than the 23 million tons assessed Apparently, because of developing working class eating more eatery suppers!

1. Diagram: showcase examination Transportation of vegoils Malaysia & Indonesia send out exchange: 2005 27.5 million tons 2006 29.4 million tons Malaysian fare of palm oil: 2004/05 12,634 million tons 2005/06 13,770 million tons 2006/07 13,840 million tons Double Hull tankers expanding predominance: 2005 53% 2006 60% Source: Malaysian Palm Oil Board

1. Review: advertise investigation Transportation of vegoils

1. Diagram: showcase investigation Major thought going into 2007; the re-categorisation of vegetable oils and the need to convey these cargoes in twofold body compound tankers

2. MARPOL Annex II For simplicity of understanding Annex II can be partitioned into two clear segments: i. Contamination classes ii. Transport sort prerequisites Additionally there are likewise the: iii. Operational necessities (for the genuine/physical carriage of chemicals in mass)

2. MARPOL Annex II: Pollution classification Early 1990's IMO started survey of MARPOL Annex II controls International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code) Why? Article upgrades Adaptation to the overhauled GESAMP technique Reduce the quantity of classifications Simplification of operational necessities Fewer non-controlled substances Reduction of lawful releases Keeping up with specialized improvement Adaptation to the Global Harmonized System (GHS)

2. MARPOL Annex II: Pollution order Previously there were 5 contamination classifications inside Annex II: classes A, B, C, D and an Appendix III Appendix III recorded items to which the IBC Code did not have any significant bearing As of 1 st January 2007 we have 3+1 contamination classification framework: X, Y, Z and OS or Other Substances - incorporates squeezed apple, earth slurry, coal slurry, dextrose arrangement, glucose arrangement, kaoline slurry, molasses and water Vegetable oils now updated from Appendix III (of the IBC Code) to Pollution Category Y Oil like substances do not exist anymore (xylene, toluene, pentanes now require CoF and can never again be carried on item tankers)

2. MARPOL Annex II: Ship sorts What is an IMO Ship Type? The International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk IBC Code gives itemized benchmarks to the development and gear of three sorts of compound tankers (Types 1, 2 and 3) The mass carriage of any fluid item other than those characterized as oil (subject to MARPOL Annex I) is disallowed unless the item has been assessed and classified for incorporation in Chapter 17 or 18 of the IBC Code

2. MARPOL Annex II: Ship sorts IMO Ship Type 1 is a synthetic tanker expected for the transportation of items considered to introduce the best general danger. The amount of load required to be conveyed in a Type 1 ship ought not surpass 1,250 m3 in any one tank IMO Ship Type 2 is expected to transport items with obviously extreme ecological and security perils which require noteworthy preventive measures to block escape of such payload. The amount of load required to be conveyed in a Type 2 ship ought not surpass 3000 m3 in any one tank IMO Ship Type 3 is a synthetic tanker proposed to transport items with adequately extreme natural and security perils. These items require a direct level of regulation to expand survival ability in a harmed condition. There is no filling limitation for chemicals doled out to Ship Type 3

2. MARPOL Annex II: Ship sorts Cargo Tank Location 2.6.1 Cargo tanks should be situated at the accompanying separations inboard: .1 Type 1 ships: from the side shell plating, at least the transverse degree of harm indicated in 2.5.1.1.2, (B/5 or 11.5m whichever is less), and from the formed line of the base shell plating at centreline, at the very least the vertical degree of harm determined in 2.5.1.2.3, (B/15 or 6 m whichever is less), and no place under 760 mm from the shell plating. This necessity does not have any significant bearing to the tanks for weakened slops emerging from tank washing. .2 Type 2 ships: from the shaped line of the base shell plating at centreline, at least the vertical degree of harm indicated in 2.5.1.2.3, (B/15 or 6 m which ever is less), and no place under 760 mm from the shell plating. This necessity does not have any significant bearing to the tanks for weakened slops emerging from tank washing. .3 Type 3 transports: no requirement"

2. MARPOL Annex II: Operational prerequisites Stripping necessities (1) The amended stripping points of confinement will significantly decrease the measure of deposits that vessels will be permitted to release into the marine condition Ships built before 1 July 1986 might be furnished with a pumping and funneling course of action to guarantee that each tank ensured for the carriage of substances in Category X or Y does not hold an amount of buildup in abundance of 300 liters in the tank and its related channeling and that each tank confirmed for the carriage of substances in Category Z does not hold an amount of deposit in overabundance of 900 liters in the tank and its related channeling. An execution test might be required to be done. Each ship developed on or after 1 July 1986 however before 1 January 2007 should be furnished with a pumping and channeling course of action to guarantee that each tank affirmed for the carriage of substances in Category X or Y does not hold an amount of buildup in overabundance of 100 liters in the tank and its related funneling and that each tank confirmed for the carriage of substances in Category Z does not hold an amount of deposit in abundance of 300 liters in the tank and its related channeling.

2. MARPOL Annex II: Operational prerequisites Stripping necessities (2) Every ship developed on or after 1 January 2007 might be furnished with a pumping and channeling game plan to guarantee that each tank ensured for the carriage of substances in Category X, Y or Z does not hold an amount of buildup in overabundance of 75 liters in the tank and its related funneling. After 1 January 2007, the stripping execution necessities will apply to all tankers holding a Certificate of Fitness (CoF).

2. MARPOL Annex II: Operational prerequisites Underwater release necessities The submerged release game plan for tank washing water is required for contamination classes X and Y for boats bottom laid before 1 January 2007. New structures will require such for all contamination classifications X, Y and Z. Classification Z items will be exempted from the submerged release necessity, albeit new vessels will be required to go along.
