MARPOL – Pollution from Ships Record Books

Introduction

The MARPOL Convention, or International Convention for the Prevention of Pollution from Ships, is one of the main international instruments for protecting the marine environment. It regulates discharges from ships, including those related to oil, noxious liquid substances, sewage, garbage and air emissions. Its implementation relies on control procedures, certificates and record-keeping documents such as MARPOL Record Books, which are essential for ensuring the traceability of operations carried out on board.

MARPOL pollution record books, also known as Record Books, are used to record operations that may have an impact on the marine environment. They are therefore both operational documents for the crew and essential evidence during flag State inspections, Port State Control inspections and compliance audits.

MARPOL documentation directly concerns merchant ships, oil tankers, chemical tankers, passenger ships, bulk carriers, offshore vessels and other ships subject to international pollution-prevention requirements.

What Is a MARPOL Record Book?

A MARPOL Record Book is a regulatory record in which certain operations carried out on board must be entered accurately. It provides a chronological record of operations involving oil, noxious liquid substances, garbage or certain atmospheric emissions.

The proper maintenance of the record serves several purposes:

• ensuring traceability of operations carried out on board;

• demonstrating compliance with MARPOL requirements;

• facilitating inspections by maritime authorities;

• providing the crew with an accurate operational history;

• ensuring consistency between actual operations, shipboard equipment and regulatory documentation;

• contributing to the overall system for preventing marine pollution.

A Record Book is therefore not simply an administrative log. It constitutes documentary evidence of the ship's environmental management.

The Main Record Books Under MARPOL

The different MARPOL Annexes address different types of pollution. The main associated record books include:

• Oil Record Book – Part I, relating to machinery-space operations;

• Oil Record Book – Part II, covering cargo and ballast operations on oil tankers;

• Cargo Record Book, relating to noxious liquid substances carried in bulk;

• Garbage Record Book, concerning the management and disposal of garbage;

• records associated with certain Annex VI requirements concerning air emissions and fuel-related operations.

These documents must be used according to the requirements applicable to the ship, its type, gross tonnage, cargo and operating profile.

Oil Record Book: Recording Oil Operations

The Oil Record Book is one of the best-known MARPOL documents.

MARPOL Annex I addresses the prevention of pollution by oil. It requires numerous operations carried out on board to be recorded.

For ships concerned, the Oil Record Book Part I is used to record certain operations involving machinery spaces. Depending on the ship type and operations, this may include operations concerning oily residues, bilge water, transfers, treatment or disposal of oil residues.

For oil tankers, the Oil Record Book Part II covers cargo and ballast operations.

Entries must provide sufficient information to reconstruct an operation accurately, including the date, nature of the operation, tank concerned, quantities and other information required by the relevant form.

Accuracy is essential. An incorrectly recorded operation or an inconsistency between the Record Book, shipboard equipment and quantities handled may attract attention during an inspection.

Cargo Record Book: Noxious Liquid Substances

The Cargo Record Book is associated with MARPOL Annex II, which addresses the prevention of pollution by noxious liquid substances carried in bulk.

This record primarily concerns specialised vessels transporting liquid chemicals, particularly chemical tankers.

Recorded operations may include:

• loading of products;

• cargo transfers;

• unloading;

• tank cleaning;

• prewash operations;

• permitted discharges or transfers to reception facilities;

• certain operations involving cargo residues.

Documentary traceability is particularly important for ships calling at industrial ports such as Rotterdam, Antwerp, Hamburg, Le Havre, Marseille or Houston, where chemical and liquid bulk traffic is significant.

Garbage Record Book: Shipboard Waste Management

The Garbage Record Book concerns the management of garbage generated by ships under MARPOL Annex V.

The regulations distinguish between different categories of garbage, including food waste, operational waste, plastics, certain cargo residues, incinerator ashes and other waste generated during ship operations.

The rules are particularly strict regarding plastics, whose discharge into the sea is prohibited.

The Record Book provides a record of operations such as:

• delivery of garbage to a port reception facility;

• incineration;

• operations involving specific categories of garbage;

• accidental losses where reporting is required;

• estimated quantities and categories of garbage involved.

Document management therefore directly supports the physical management of waste on board.

MARPOL and Port Operations

MARPOL Record Books become particularly important during port calls.

In ports such as Le Havre, Rotterdam, Antwerp, Singapore, Marseille or Hong Kong, ships may be subject to different forms of documentary inspection. Authorities may verify the consistency between Record Books, shipboard equipment, certificates and operations carried out during previous voyages.

Traceability makes it possible to determine what happened to residues and waste generated during a voyage.

Port reception facilities also play a fundamental role in MARPOL implementation. Oil residues, garbage, sewage and cargo residues may have to be delivered to specialised reception facilities rather than discharged at sea.

MARPOL in Major Maritime Areas

MARPOL requirements apply internationally and therefore cover the world's major commercial shipping routes.

In the English Channel and North Sea, ships serving Le Havre, Dunkirk, Rotterdam, Antwerp or Hamburg operate in an area characterised by high traffic density and extensive port activity.

In the Mediterranean Sea, routes linking Marseille, Genoa, Barcelona, Valencia, Naples and Turkish ports are also subject to international pollution-prevention requirements.

In the Atlantic Ocean, ships operating between Europe, Africa and North America must apply the same fundamental principles of environmental management.

The routes of the Indian Ocean, Red Sea, Persian Gulf, Pacific Ocean and Asian maritime regions are also directly concerned.

For voyage planning and monitoring, MARPOL Record Books form part of a broader maritime documentation system that includes IMO regulatory publications, hydrographic documentation and nautical charts published by organisations such as Shom, Admiralty, Imray and NV Charts.

Record Books and Port State Control

Port State Control, or PSC, is one of the main contexts in which MARPOL records may be examined.

During an inspection, authorities may look for inconsistencies between:

• Record Book entries;

• quantities of residues generated;

• tank capacities;

• treatment equipment;

• ship certificates;

• operations carried out in port;

• receipts from reception facilities;

• information contained in deck or engine-room logs.

The quality of Record Book entries is therefore an important element of regulatory compliance.

An entry should be legible, chronological, consistent and completed in accordance with the applicable procedures.

Paper MARPOL Record Books and Electronic Records

Traditionally, MARPOL Record Books have been associated with regulatory paper forms. The development of digital maritime systems has also made it possible, under certain conditions, to use approved electronic record books.

The principle remains the same: a regulatory operation must be recorded reliably and must remain available for subsequent verification.

Digital systems can facilitate:

• searching for previous operations;

• data retention;

• onboard document management;

• internal compliance checks;

• communication of information to the shipping company;

• reduction of transcription errors.

However, an electronic system cannot simply be treated as an ordinary computer file. It must meet the applicable requirements and receive approval where such approval is required.

Why Use Up-to-Date MARPOL Documentation?

International maritime regulations evolve regularly. Amendments adopted by the IMO may change requirements applicable to particular operations, forms or record-keeping procedures.

Having a MARPOL Record Book that corresponds to the applicable regulations is therefore essential.

For merchant marine officers, QHSE managers, masters, chief engineers, environmental officers and shipping companies, regulatory documentation should be regarded as an operational tool.

It should make it possible to answer a fundamental question quickly:

What operation was carried out, when, where, on which equipment, in what quantity, and what happened to the resulting residues or waste?

Who Uses MARPOL Record Books?

This documentation is relevant to:

• masters and merchant marine officers;

• chief engineers;

• safety and environmental officers;

• shipping companies;

• shipowners and ship managers;

• oil tankers and chemical tankers;

• cargo vessels;

• passenger ships;

• offshore vessels;

• technical and QHSE departments;

• maritime schools and training centres;

• regulatory compliance professionals;

• professionals involved in ship inspections and audits.

MARPOL: A Documentation System for Protecting the Oceans

MARPOL Record Books – Pollution from Ships are an integral part of the international framework for preventing marine pollution.

They transform regulatory requirements into day-to-day operational traceability. Every properly recorded operation helps demonstrate that oil residues, noxious substances, garbage and other pollutants are managed in accordance with the applicable rules.

This approach is particularly important in heavily trafficked maritime areas such as the North Sea, English Channel, Mediterranean Sea, Atlantic Ocean, Red Sea, Indian Ocean and Pacific Ocean.

The proper use of MARPOL Record Books therefore contributes directly to protecting marine ecosystems and maintaining ship compliance during international voyages.

Conclusion

MARPOL Record Books and ship pollution records are essential documents within international maritime regulations. Oil Record Books, Cargo Record Books, Garbage Record Books and other associated records document operations that may affect the marine environment.

For a professional vessel, their importance goes far beyond an administrative obligation. They provide operational traceability, facilitate inspections, demonstrate regulatory compliance and support rigorous management of marine pollution.

Properly selected and up-to-date regulatory documentation is therefore an essential component of the environmental management system of any vessel operating on the world's major commercial shipping routes.
