MARPOL Annex on Oil

Study the protocols of the MARPOL Convention in the prevention of oil pollution from ships in this free online course.

Publisher: ADU
‘MARPOL Annex on Oil’ is a free online course that discusses the protocols of the MARPOL Annexes (also called the International Convention for the Prevention of Pollution from Ships). You will learn about the exemptions, applications and waivers to the protocols of MARPOL and the history of how certain of its annexes came into being.

The MARPOL Annex I deals with the prevention of pollution by oil from ships and tankers, and came into effect on 2 October 1983. This annex regulates the methods and means of controlling the discharge of oil into the ocean and marine environments. With oil being carried as cargo on board tankers and used as fuel for marine diesel engines, waste oil is generated as unpumpable residue in cargo tanks and also as sludge from the purification of fuel and lubricating oils. Drainage from fuel tanks, leak-offs from machinery operation and exhausted lube oils also collect in fuel and lube oil sludge tanks. Marine pollution is caused when these waste oils are discharged into the sea during tank-cleaning operations, during the discharge of ballast taken into cargo tanks or as direct discharges from machinery space without using an oily water separator (OWS). The discharge monitoring and control system have contributed greatly to a noticeable decrease in the oil contamination of the world’s seas. The MARPOL convention introduced a number of radical new concepts, such as a requirement for new oil tankers to be fitted with segregated ballast tanks so as to obviate the need to carry ballast water in cargo tanks. This was superseded by the requirement for oil tankers delivered from 1996 onwards to be fitted with a double hull. The protection of the marine environment was thus greatly enhanced.

‘MARPOL Annex on Oil’ is a free online course that teaches you about the definitions, applications and port state controls (PSC) as well as reports contained in the articles and protocols of the MARPOL Convention. It also covers detection of violations, undue delay to ships as well as signatories’ general obligations. You will study the applications and exemptions of MARPOL Annex I on the pollution by ships due to oil spillage. Learn about the various waivers as well as the equivalents in cases where the applications of Annex I cannot be upheld, and analyze its survey requirements. Grapple with the Condition Assessment Scheme (CAS) and the Condition Assessment Program (CAP). You will also be taught about the duration and validity of the IOPP Certificate (International Oil Pollution Prevention Certificate) as well as its various statutory certificates, requirements and issuances.

This free online course aims to give you the knowledge necessary to understand pollution prevention methods and operations in the marine environment. As a learner, you will study the requirements and conditions for machinery spaces as well as the usage of tools, amendments, and exemptions to the norms of tanks for oil residues. Examine the conditions for the applications of oil fuel tank protection on tankers and vessels by virtue of their position, state and capacity. Learn about the basic functionalities of the bilge alarm and oil content monitors. You will also learn about the basic operations that carry out the functions of the separation of oily water as well as the common errors and best practices of the Oil Record Book (ORB). This course will be of significant interest to marine engineering, coastal conservation and maritime law students and professionals.
