The maritime industry is one of the most regulated in the world, and proving your competence is a non-negotiable part of the job. One of the most common and feared tools for this is the CES test. Whether you are a cadet looking for your first contract or a seasoned Chief Engineer, passing the CES examination is often the final hurdle before you can step on board.
In this guide, we will break down everything you need to know about the CES exam, how it works, and how you can prepare to pass it with flying colors.
What is CES Test?
The CES test (Crew Evaluation System) is an online assessment tool used by shipping companies worldwide to evaluate the professional knowledge of seafarers. Originally developed by Seagull Maritime AS, it is now part of the Ocean Technologies Group (OTG) ecosystem.
The system is designed to test a seafarer’s knowledge against the STCW (Standards of Training, Certification, and Watchkeeping) requirements. It isn’t just a general knowledge quiz; it is a specialized CES marine test that measures your ability to handle specific duties on different types of vessels.
Who Needs to Pass the CES Exam?
Almost every rank on a modern merchant vessel may be required to take one or more CES exams during their career. The test is typically divided by department and level of responsibility:
- Deck Officers: Master, Chief Officer, and OOW (Officer of the Watch, Operational level).
- Engineers: Chief Engineer, Second Engineer, and EOW (Engineer Officer of the Watch).
- Cadets: Both Deck and Engine cadets seeking their first placements.
- Ratings: Able Seamen (AB), Oilers, and support staff.
Whether you are applying to a new company or undergoing a promotion review, the CES test for seafarers is the industry standard for verification.
Different Versions (4.0, 5.0, 6.0, 6.1)
Over the years, the system has evolved to keep up with maritime regulations and technology. While you might still hear mentions of older versions like CES 4.0 or 5.0, most modern companies have migrated to the latest iterations, including sub-versions like 6.0.16 as of 2026.
- CES 4.0 & 5.0: Older versions that focused on basic STCW 95 requirements.
- CES 6.0 & 6.1: The latest versions featuring updated user interfaces, cloud-based synchronization via the Ocean Learning Academy, and questions reflecting the STCW 2010 Manila Amendments, with recent additions for sustainability, cybersecurity, and post-COVID norms in 2026 updates.
The primary difference in the newer CES tests is the depth of the question database and the inclusion of more scenario-based challenges.
| Version | Focus | Key Differences |
|---|---|---|
| 4.0 & 5.0 | Basic STCW 95 | Simple questions, limited scenarios |
| 6.0 & 6.1 (incl. 6.0.16) | STCW 2010 + modern amendments | Deeper database, scenario-based, cloud integration, new topics like cybersecurity and sustainability |
How CES Examination Works
The format of the CES examination can vary depending on your rank and the specific requirements of your employer.
- Number of Questions: Usually ranges from 30 to 60+ questions per test.
- Time Limit: Typically, you are given 45 to 90 minutes.
- Passing Score: While the system’s “general” pass mark is often around 50–70 %, many top-tier shipping companies (like Maersk, MSC, or V.Ships) set their own internal standards. For senior officers, a score of 80 % or 90 % may be required in specific critical areas.
- Retakes: If you fail, the “cool-down” period for a retake depends entirely on your company’s policy. Some allow an immediate second attempt, while others may require you to wait weeks or undergo additional training.
Why CES Test Is Difficult
Many seafarers find CES exams intimidating for several reasons:
- Technical English: The questions use precise maritime terminology that can be tricky, even for fluent speakers.
- Scenario-based Questions: You aren’t just asked for facts; you are given a situation and must choose the best action according to international regulations. For example: “On an oil tanker, you detect a minor oil spill during bunkering – what is the immediate action per MARPOL Annex I?” (Correct: Stop operations and notify the master).
- Company-Specific Requirements: High-stakes environments mean that a “pass” isn’t always enough—you need a high score to stand out to recruiters.
Other examples include: “How to respond to a cybersecurity alert on bridge equipment?” or “What sustainable practices apply to ballast water management under IMO guidelines?”

FAQ
Can I take the CES test at home?
Most companies require you to take the test in a controlled environment (like a crewing office), but some now offer remote testing through the OTG cloud platform.
Is the CES test the same as SETS or Marlins?
No. While all evaluate seafarers, Marlins focuses on English proficiency, whereas the CES test evaluates professional and technical competence.
Are the questions the same for all ships?
No, the test is tailored to your vessel type (e. g., Oil Tanker, Bulk Carrier, Container) and your specific rank.
How does CES account for new technologies like autonomous vessels?
Newer versions include questions on emerging tech, but focus remains on STCW core competencies; check OTG for updates.
Can I appeal CES results?
Yes, through your company or OTG support, but policies vary.
What is the cost of taking the CES test?
It’s usually free for company employees or applicants, but confirm with your employer.
