What is a Seaman Book or CDC?

Seaman Book is one of the requirements you need if you want to work on a ship or any maritime job. Like a passport, the book will verify your identification and if you are capable to work as a seaman. A Seaman Book is also known as CDC or Continues Discharge Certificate. This document is needed if you are a seafarer and getting on board. It will certify a Seafarer as the evidence of his all services done.

You can only get this record book once you pass a maritime training. Many maritime schools offer trainings, but make sure you got a training center that certified by the Maritime Industry Authority. (Visit http://www.pntc.edu.ph/, they are one example of maritime training center here in the Philippines.) Let’s know about what is a seaman book is.

Seaman Record Book
  • Once you got on board, the captain will sign the book that shows that you are part of the boarding ship included the time duration and position.
  • A CDC is mostly valid for 10 years and need to renew 6 months before its expiry date. But if you are still on board when the CDC expires, the end day of your trip will be considered as your CDC expiration date.

  • Every country has their authority agencies that issue this book. In the Philippines, MARINA is the one who handles maritime industry and they are also the one who issue a record book. See how to get the seaman book in the Philippines.

  • The Seaman Record Book contains information about the Seafarer. His/her basic information, country, birth place, past jobs done and feedback from the captains. It is a vital record you need to know in any seaman. And in case it lost or something happens, case of emergency information is included in the book.

  • The CDC all over the world have the same format. This is why it is easy to understand its contents.

  • A Seaman Record Book is an important weapon to a seaman without this they can’t travel.


  • I hope this will help you to know more what a Seaman book is and its purpose.
