MARPOL 73/78 has got 6 annexes which deals with pollution caused by merchant vessels. All annexes have chapters and each chapter has regulations which deal with pollution prevention caused by merchant vessels. as a chief engineer one has huge responsibility that vessel is complying with all the regulations of MARPOL. To ensure this he should check the following in general and for annex 1 in particular:- 1) CERTIFICATION :- Statutory certification of ships complying with the requirement of the MARPOL regulations acts as an aid to ensure adherence to international regulation. Annex 1, II, IV and VI gives IOPPC, IPPC, ISPPC and  IAPPC to ships which comply with the regulations laid down in the respective annexes. Like IOPP certificate is issued after initial survey before ship is put in service or renewal survey in accordance with regulation 6 of annex I, to all ships of 400 Gt and above and to all oil Tankers of 150 Gt and above, by administration or an RO. C/E should check that the

Notify party:- is the party who must be informed by the carrier of the ship's arrival. INCOTERMS :- is a set of rules, published by International chamber of commerce, for uniform interpretation of the m

Contamination of Products in Product carrier To carry different types of product simultaneously in a product carrier is a big challenge. Products can be contaminated because of following reasons:- Liquid contamination due to overfilling a tank. Vapor contamination through inert gas main Low flash point cargoes can contaminate the high flash cargoes To prevent the contamination of products with different contaminants precautions are as follows:- From water:- For loading critical cargoes such as aviation kerosene or lub oil, care should be taken to achieve a compatible standard of preparation throughout that portion of cargo system allocated to critical product.              .a) The cargo lines which are to load or discharge the critical product, should be opened and                           drained dry. This includes manifolds, droplines, pump discharge lines and tank suction lines.               b) Cargo pumps and their associated air vessels, strainers and by-pass

Oil product tankers are non-specialized tankers below 60,000 dwt as well as coated tankers above this size. These ships carry a spectrum of cargoes, ranging from relatively unsophisticated dirty products such as fuel oil through to clean products such as naphtha. Vessel that trade at one end of this spectrum are unlikely to be able to switch easily to the other end. At the most sophisticated end of the fleet there is an overlap with the chemical sector with a significant volume of swing tonnage that can operate in either.                Chemical tankers are modern parcel tankers with either full or partial S.S. tanks that cover the sophisticated end of the chemical market, for which IMO grade 1/11 is required.           Many product tankers are purpose built with coated tanks and have sophisticated pumping system capable of handling 12 or more grades.       So, basically product carriers are of two types:- 1) Dirty product carrier ( fuel oil and heating oil) 2) Clean product carr
