Advanced Chemical Tanker Cargo Operations is the STCW Reg V/1-1 endorsement for officers and crew with immediate responsibility for cargo on chemical tankers, assessed to Table A-V/1-1-3. Candidates must first hold the basic oil/chemical tanker certificate and have at least three months of approved chemical-tanker service or approved onboard training. The roughly five-day approved course covers chemical tanker design (IMO ship types 1/2/3, stainless-steel and zinc/epoxy tanks, deepwell pumps, heating, dedicated lines, ESD), the IBC Code (Certificate of Fitness, Chapter 17 carriage requirements, P&A Manual), cargo properties and the compatibility/segregation chart, inhibitors and inhibitor certificates, cargo operations (ullaging, nitrogen padding, vapour return, prewash and the MARPOL Annex II categories X/Y/Z with the 75-litre stripping standard and en-route discharge criteria), gas detection (oxygen, LFL/UFL, TLV/PEL), and health hazards, first aid (MFAG) and emergency response. Assessment is pass/fail against the provider's standard, commonly a multiple-choice written test plus practical demonstration.

About the Adv. Chemical Tanker Exam
The STCW Advanced Chemical Tanker Cargo Operations course meets Regulation V/1-1 and the competence standard in Table A-V/1-1-3 of the STCW Code for masters, chief mates, chief and second engineers and any person with immediate responsibility for cargo on chemical tankers. It builds on the basic oil/chemical tanker certificate and covers chemical tanker design and systems, the IBC Code and Certificate of Fitness, cargo properties and compatibility, MARPOL Annex II, gas detection, and emergency response. Most flag-state-approved centres deliver about a five-day course with a written (commonly multiple-choice) assessment plus practical evaluation. Prerequisites are the basic certificate and three months of approved chemical-tanker service or approved onboard training.

Frequently Asked Questions
What is the STCW Advanced Chemical Tanker Cargo Operations certificate?
It is the STCW Regulation V/1-1 endorsement, assessed to Table A-V/1-1-3, required for masters, chief mates, chief and second engineers and anyone with immediate responsibility for cargo on chemical tankers. It covers chemical tanker design, the IBC Code, cargo compatibility, MARPOL Annex II and emergency response.
What are the prerequisites for the advanced course?
Candidates must already hold the basic training certificate for oil and chemical tanker cargo operations and have completed at least three months of approved seagoing service on chemical tankers, or an approved period of onboard training, before sitting the advanced course.
Is the assessment multiple choice?
STCW sets a competence standard, not a fixed exam. Most flag-state-approved centres use a written end-of-course assessment that is commonly multiple choice, combined with practical or simulator demonstration assessed against the Table A-V/1-1-3 criteria. The pass mark is set by the provider, often around 70 percent.
What is the IMO ship type system on chemical tankers?
The IBC Code assigns each cargo a required ship type. A Type 1 ship carries the most hazardous products with maximum preventive measures, Type 2 covers appreciably severe hazards, and Type 3 covers products needing a moderate degree of containment. The type governs tank location and damage survival.
What does MARPOL Annex II require for tank residues?
Annex II categorises noxious liquid substances as X, Y or Z. Ships built on or after 1 January 2007 must strip tanks to no more than 75 litres of residue. Category X tanks require a mandatory prewash to a reception facility; permitted residue discharge to sea must be en route at 7 knots, 12 nm from land, in 25 m of water, below the waterline.
Why are inhibitor certificates important?
Reactive cargoes such as styrene carry an inhibitor to prevent polymerisation. The shipper must provide an inhibitor certificate stating the inhibitor type, quantity, date added and duration of effectiveness, and whether the inhibitor needs oxygen, so the crew can manage temperature and tank atmosphere safely.
How long is the course and how often must it be refreshed?
The approved course is typically about five days. The certificate of proficiency is generally retained, but seafarers must meet the flag-state's continued-competence and document-revalidation requirements, including recent relevant seagoing service, to keep their endorsement valid.
