What Is a Seaman Book and Why Seaman Book Renewal Matters

A seaman book (also called a CDC — Continuous Discharge Certificate — or SIRB) is the official record of a seafarer’s sea service and a mandatory identity document for signing on to a vessel. It is issued by a national maritime authority and must remain valid throughout your employment at sea.

A seaman book renewal is the process of extending or reissuing a seafarer’s Continuous Discharge Certificate (CDC) or Seafarer’s Identification and Record Book (SIRB) before or after it expires. It is handled by the issuing maritime authority — such as DG Shipping (India), MARINA (Philippines), or the Panama Maritime Authority — and typically requires a valid passport, medical certificate, and current STCW credentials.

Sail with an expired book and you risk being refused sign-on, failing port state control checks, and losing contract offers while you wait out normal processing times.

Seaman Book Renewal by Country

Indian CDC Renewal (DG Shipping)

Indian CDCs are issued under DG Shipping and renewed through the online e-Governance portal. Typical requirements: valid Indian passport, existing CDC, seafarer medical certificate from a DG-approved doctor, and current STCW certificates. Standard validity is 10 years. Applications with mismatched passport/CDC details are a leading cause of rejection — we pre-check every field before submission.

Philippine SIRB Renewal (MARINA)

MARINA renews the SIRB through its online appointment system, with biometric capture at a MARINA office. Requirements include a valid passport, the old SIRB, and supporting sea-service or training documents. SIRB validity is 10 years. Appointment slots in Manila fill quickly — we book and prepare your file in advance.

Panama Seaman Book Renewal (PMA)

Panama seaman books are issued by the Panama Maritime Authority, usually through authorized agents worldwide, which makes them a common choice for seafarers on Panama-flagged vessels. Renewal generally requires a valid passport, photo, medical fitness certificate, and your current or expired book. Processing through an authorized agent typically takes days rather than weeks.

Other Flag States (Liberia, Marshall Islands, Honduras & more)

متى يجب عليك التجديد؟

ابدأ قبل 3-6 أشهر من انتهاء الصلاحية. تقبل العديد من السلطات التجديد المبكر، وتتطلب شركات الشحن عادةً ما لا يقل عن 6 أشهر من الصلاحية المتبقية عند التوقيع. إذا انتهت صلاحية كتابك بالفعل، فلا يزال التجديد ممكنًا في معظم الولايات القضائية، على الرغم من أن بعض السلطات تطبق خطوات تحقق إضافية — اتصل بنا قبل حجز أي فحوصات طبية حتى لا تدفع مقابل اختبارات بترتيب خاطئ.
