Whether you are preparing for your first assignment aboard a commercial vessel, joining a cruise ship, working on a private yacht, or advancing your career in the maritime industry, having the correct documentation is an essential part of getting underway.

One document frequently requested by maritime employers is the Seaman Book, sometimes referred to as a Seafarer’s Service Book, Seaman’s Discharge Book, or Seafarer’s Identity Document.

Although these terms are sometimes used interchangeably, they do not always describe legally equivalent documents.

At the World Academy of Safety & Health (WASH), we recognize that proper maritime preparation involves more than obtaining a single document. Seafarers must understand training requirements, medical qualifications, employment documentation, and applicable maritime regulations before joining a vessel.

This guide explains the process of obtaining a Seaman Book and the important considerations every aspiring or experienced maritime professional should understand.

A Seaman Book is a document issued by an authorized maritime administration to eligible seafarers.

What it records

• The seafarer’s identifying information and photograph
• Document identification and issuing authority
• Vessel assignments and employment history
• Dates of embarkation and disembarkation
• Sea-service experience
• Other maritime employment information required by the issuing authority

These records can be valuable when applying for maritime positions, documenting professional experience, or meeting eligibility requirements for certain maritime qualifications.

A Seaman Book may serve as an official record of maritime employment, vessel assignments, and accumulated sea service. Depending on the issuing administration and the document type, it may also help establish your status as a professional seafarer.

However, requirements vary considerably between countries, maritime administrations, vessel operators, and positions aboard a vessel.

Seaman Book vs. Seafarer’s Identity Document

Not necessarily the same. A Seaman Book or discharge book primarily documents maritime service, while a Seafarer’s Identity Document may serve a separate identification purpose under applicable national laws and international conventions.

For example, the International Labour Organization’s Seafarers’ Identity Documents Convention (Revised), 2003 (No. 185), establishes requirements for qualifying seafarers’ identity documents issued by countries applying that convention.

The first step is determining which country or maritime administration can legally issue the document you need.

Eligibility may depend on

• Your citizenship or residency
• The country where you are employed
• Your maritime qualifications
• The flag under which your vessel operates
• Your employer’s documentation requirements
• Whether you are a new or experienced seafarer

Some maritime administrations issue service books primarily to their own citizens or residents. Others may offer documentation to eligible foreign seafarers under specific circumstances.

A vessel’s flag state may also influence the documentation required for a particular assignment.

Although requirements differ between issuing authorities, many applications involve a combination of personal identification, employment records, and maritime qualifications.

Some authorities may request additional documentation, including certified copies, translations, proof of residency, or specific employer endorsements. Review the official checklist carefully before submitting your application.

Obtaining a Seaman Book does not, by itself, qualify someone to perform professional duties aboard a vessel. Depending on your position and the applicable regulations, you may need additional maritime safety training before employment.

The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) establishes internationally recognized minimum training and certification standards for seafarers serving on applicable vessels. STCW Basic Training commonly addresses four essential areas.

The specific training and certification required depend on the vessel, position, and relevant maritime authority.

Additional qualifications

• Security awareness or designated security duties
• Proficiency in survival craft and rescue boats
• Advanced firefighting
• Medical first aid or medical care
• Passenger vessel safety training
• Officer or engineering qualifications
• Specialized offshore or vessel-specific training

WASH encourages maritime professionals to review their entire qualification portfolio before accepting an assignment.

Medical fitness is an important component of maritime employment. Depending on the position, vessel, and applicable maritime regulations, seafarers may be required to hold a valid medical certificate issued by an appropriately authorized medical practitioner.

Medical assessments may evaluate areas such as vision, hearing, physical fitness, and the ability to perform assigned duties safely.

Some employers or maritime administrations specify particular medical examination standards or approved providers.

Before scheduling an examination, confirm

• Which medical certificate is required
• Who is authorized to conduct the examination
• Whether your employer accepts the certificate
• How long the certificate remains valid
• Whether additional medical assessments are necessary

Medical requirements should be verified independently of the Seaman Book application process.

Once you have confirmed your eligibility and assembled the required documents, you can proceed through the application process established by the issuing authority.

Depending on the jurisdiction, applications may be accepted through an official maritime administration, an authorized online portal, a designated office, a consular service, or an approved representative.

Review before submission

1. You selected the correct document and issuing authority.
2. Your application is complete and accurately signed.
3. Your passport and supporting documents are valid.
4. Required training and medical records are included.
5. Photographs and scanned documents meet the specifications.
6. Applicable fees and delivery arrangements are understood.

Keep copies of your application and any official confirmation numbers. If original documents must be submitted, use a secure delivery method and follow the authority’s instructions.

Processing times vary depending on the issuing administration, application type, document completeness, and delivery arrangements.

Additional time may be required for document verification, corrections, medical examinations, training completion, or international shipping.

If you are preparing for a specific vessel joining date, begin the application process as early as practical.

Avoid making non-refundable travel arrangements based solely on an estimated document issuance date. Some authorities may offer expedited processing, but availability and eligibility must be confirmed directly.

Receiving your Seaman Book is not the end of your documentation responsibilities. Maritime professionals should regularly review their employment and certification records to ensure they remain accurate and current.

Keep these current

• Passport and applicable visas
• Seaman Book or discharge book
• Seafarer’s Identity Document, if required
• STCW certificates and endorsements
• Medical fitness certificate
• Certificates of competency or proficiency
• Vessel-specific training records
• Sea-service documentation

Maintaining organized records can help reduce administrative difficulties during recruitment, contract renewals, and vessel transfers.

The World Academy of Safety & Health (WASH) supports maritime safety education, professional development, and workforce readiness through its Maritime Safety Division.

Through WASH maritime training initiatives and its collaboration with Maritime Expert Solutions, maritime professionals can explore a broad range of online maritime safety courses, including STCW-related and other specialized training topics.

Our goal is to help individuals and organizations strengthen their understanding of maritime safety responsibilities, emergency preparedness, and professional training requirements.
