Cargo Record Book (Record Book for Noxious Liquid Substances)

MARPOL Annex II requires the Cargo Record Book for every ship certified to carry NLS in bulk, with defined signatures, availability and retention, and prewash control by the surveyor authorised by the competent Government.

MARPOL Annex IICargo Record BookNLSchemical tanker

Operational Explanation

The Annex II Cargo Record Book promptly records Appendix 2 operations. Each entry is signed by the officer or officers in charge and each completed page by the Master. For Category X, endorsement, alternative procedure or exemption involve the surveyor appointed or authorised by the Government of the receiving Party and the approved P&A Manual.

Regulatory Reference

MARPOL Annex II, Regulations 2, 13, 15 and 16. The book remains readily available, on board except for an unmanned ship under tow, and is retained for three years after the last entry. The Government of the receiving Party appoints or authorises surveyors and grants prescribed exemptions.

Scope of Application

Every ship to which Annex II applies: every ship certified to carry Noxious Liquid Substances in bulk, including an oil tanker when so certified.

Procedure / How to Complete It

  1. Promptly record each Appendix 2 operation with the applicable code and particulars.
  2. Have each entry signed by the officer or officers in charge and each completed page by the Master.
  3. For Category X follow the P&A Manual and ordinary procedure: prewash before departure, effluent to the reception facility until ≤0.1% by weight and then until the tank is empty, endorsed by the authorised surveyor.
  4. Use the Regulation 13.6.3 alternative only when accepted by the competent Government; separately document any exemption under Regulations 13.4 and 16.6–16.7.
  5. Keep the book available and retain it for three years after the last entry.

Practical Example

Category X: prewash under the P&A Manual; samples analysed by the surveyor appointed or authorised by the Government of the receiving Party until ≤0.1% by weight, discharge to the reception facility until tank empty, and endorsed entry. If measurement is impracticable without undue delay, use only the formally accepted alternative procedure.

What Typically Goes Wrong

Restricting the book to chemical tankers, confusing entry and page signatures, or assigning endorsement and exemption to a generic terminal surveyor.

Common Mistakes Mistake Library

Entry and page signatures confusedIncomplete recordCheck responsible-officer and Master signatures
Analytical procedure treated as the only possible routeFormally accepted alternative is ignoredDistinguish ordinary route, Regulation 13.6.3 and exemption

What the PSCO Checks

Scope, prompt and complete entries, officer and Master signatures, three-year retention, consistency with the P&A Manual and endorsement by the authorised surveyor.

FAQ

Is the Cargo Record Book only for chemical tankers?
No. It applies to every ship certified to carry NLS in bulk.
Who signs?
Each entry is signed by the officer or officers in charge; each completed page by the Master.
Must analysis always continue to 0.1%?
That is the ordinary Category X route; Regulation 13.6.3 permits an alternative when accepted by the competent Government.
Who may endorse the operation?
The surveyor appointed or authorised by the Government of the receiving Party, not a terminal surveyor merely as such.
