Calculate sea service for an international certificate

To obtain a certificate of competency for an international (STCW) certificate, you must have approved seagoing service.

Sea service should be assessed in accordance with Marine Order 70 (Seafarer certification 2014, Marine Order 71 (Master and deck officers) 2023, Marine Order 72 (Engineer officers), Marine Order 73 (Ratings) and Marine Order 74 (Masters and deck officers—yachts).

How to calculate sea service

Your sea service is calculated by counting up all your individual working days. 

For example, if you have served 27 days on a voyage and 30 days on another, your combined sea service is 57 days This can be converted to months and days by dividing by 30 which is considered to be one month. We will therefore consider 57 days to be one month and 27 days of sea service.

Recording your training  

You can record your onboard training in the following ways: 

• Training record book for STCW engineer watchkeeper. 
• Documented training programs for STCW deck watchkeeper that includes a training record book (STCW watchkeeper deck 18 and 24 month pathways only). 
• Task and guided study books (TAGS books) for STCW rating.

Calculating sea service for specific qualifications

International deck certificate

If you perform master or deck officer duties or functions for:

• At least 8 hours in a 24 hour period:

calculate sea service as a whole day (and no more than a whole day).

If you perform master or deck officer duties or functions for:

• Less than 8 hours in a 24 hour period:

calculate sea service for the actual hours served plus 25 per cent of that time.

This applies whether you live on board or not.

Qualifying sea service is calculated in Schedule 3.2 and 3.3 of Marine Order 71 (Master and deck officers) 2023.

Qualifying sea service must be confirmed by a letter issued by the company. Letters issued on board a vessel by a master will not be accepted

Training programs for international deck watchkeeper 

Complete one of following training programs that includes a training record book: 

1. An AMSA approved pre sea course and an AMSA approved monitored onboard training program for trainee deck officers.  
   • Include at least 18 months documented qualifying seagoing service on vessels ≥500 gross tonnage.
   • Perform onboard for at least 12 months on voyages of at least 24 hours duration.
2. A pre-sea course and an AMSA approved and monitored onboard training program for trainee deck officers.
   • Include at least 24 months documented qualifying seagoing service on vessels ≥500 gross tonnage.
   • Perform onboard for at least 12 months on voyages of at least 24 hours duration.
3. An AMSA approved and monitored onboard training program for Integrated ratings.
   • Include at least 24 months documented qualifying seagoing service on vessels ≥500 gross tonnage while holding a certificate of proficiency as integrated rating.
   • Perform onboard for at least 12 months on voyages of at least 24 hours duration. 

In all three options, perform at least 6 of the 12 months on voyages of at least 24 hours duration as either of the following: 

• Understudy of the officer in charge of a navigation watch on a vessel.
• Watchkeeping service equivalent to the service in sub subparagraph (A), as an officer in charge of a navigation watch on a vessel. 

Engineer watchkeeper certificate 

Qualifying sea service will count when you are doing duties or functions on a vessel and if the machinery is available or in use for:

• At least 8 hours in a 24 hour period and you are on duty or on call for that period: calculate sea service as a whole day (and no more than a whole day).
• Less than 8 hours in a 24 hour period and you are on duty or on call for that period: calculate sea service as the actual hours served plus 25 per cent of that time.

This applies whether you live on board or not.

Qualifying sea service is calculated in Schedule 3.2 and 3.3 of Marine Order 72 (Engineer officers) 2014.

Qualifying sea service must be confirmed by a letter issued by the company. Letters issued on board a vessel by a master or chief engineer will not be accepted.

How to complete your training record book

This is a mandatory requirement. 

For an international engineer watchkeeper certificate of competency you must complete a training record book and all of the following tasks on board vessels ≥750 kW propulsion power:

• Perform your duties or functions in an engine room.
• Perform your duties under the supervision of a person holding one of the following certificates of competency:
  • engineer watchkeeper 
  • engineer class 2 
  • engineer class 1
• Have the training record book signed by the chief engineer on each vessel. 
• Submit your training book for assessment by an engineer examiner or AMSA approved training organisation. (Note: If the training record book is assessed by an AMSA approved training organisation, you will need a letter from this organisation confirming you have completed all sections of the training record book.)
• Submit the assessed training book to the engineer examiner who will review it at the time of the oral examination.
• Have the training record book signed off by the engineer examiner. 

For those who have completed an engineer class 3 near coastal task book

We will accept an engineer class 3 near coastal task book for either: 

• Those completing the engineer experience training program.
• Those completing the trainee engineer program.

If you have not completed an engineer class 3 near coastal task book, you must get your training record book signed off before sending it to us. 

Do this in one of the following ways:

• If there is a higher ranking engineer on board, have them sign off the training record book. They must hold at least a certificate as marine engine driver grade 1 and above.
• If an engineer class 3 is the highest ranking engineer or sole engineer on board, we will permit the master or superintendent of the vessel to sign off on the training record book. No sea service penalties will apply.

How to apply for an international sea service assessment—masters, deck officers and engineers officers only 

Once you have met the sea service requirements for your certificate, you will need to lodge an application for a sea service assessment. 

Do this with seafarer's form 419.

If you are applying for a master, deck officer or engineer officer certificate, you will need to complete an oral examination, as instructed in your AMSA assessment letter. 

Integrated or chief integrated rating certificate

If you are doing rating or trainee duties or functions for:

• At least 8 hours in a 24 hour period, the qualifying sea service is calculated as a whole day (and no more than a whole day).
• Less than 8 hours in a 24 hour period, the qualifying sea service is calculated for the actual hours served plus 25 per cent of that time.

This applies whether you live on board or not. 

Qualifying Sea Service (QSS) is calculated in Schedule 3.2 and 3.3 of Marine Order 73 (Ratings) 2014. 

Qualifying sea service must be confirmed by a letter issued by the company.  Letters issued on board a vessel by a master will not be accepted. 

An appropriate vessel is one that is greater than 24 metres in length or greater than 750 kilowatts propulsion power. 

Navigational watch ratings, engine room watch ratings and integrated rating 

Integrated rating 

You must complete an AMSA approved training program for ratings. 

The approved training program is based on the Certificate III in Maritime Operations (Integrated Rating). This has 21 units of competency, five task and guided study books (TAGS books) and qualifying sea service (QSS). 

The 21 units of competency are divided in separate sections:

• pre-sea (certificate of safety training)
• deck rating requirements (section A)
• engine rating requirements (section B)
• units of competency common to both deck and engine room ratings (section C)

The training goes for approximately 12 or 13 weeks. This is off-the-job training at one of the approved training providers. 

Task and guided study books (TAGS books) for international rating

The approved task and guided study (TAGS) books consist of: 

• TAGS book 1—Shipboard induction, shipboard procedures, engine room duties, work health and safety/occupational health and safety requirements. 
• TAGS book 2—Survival management, survival craft, firefighting and prevention. 
• TAGS book 3—Engine room, deck machinery. 
• TAGS book 4—Ships maintenance and marine rigging.
• TAGS book 5—Dry cargo, liquid cargo, offshore vessels.

After finishing at least four months qualifying sea service and completion of TAGS book 1, you may apply at a nominated AMSA regional office to have your TAGS book 1 endorsed. This will show that you meet the requirements of keeping a navigation watch and assisting in keeping in an engine room watch. 

Navigational watch ratings and engine room watch ratings 

TAGS book 1 is also available as two separate volumes, one for navigational watch ratings (NWR) and the other for engine room watch ratings (EWR).  

These are suitable for trainees who wish to obtain a navigational watch rating certificate or engine watch rating certificate.
