SEA, CBA, STCW and MLC: Maritime Acronyms in Plain English
Acronyms can make a simple message feel like a test. Sort the useful ones into your employment documents, training standards, safety systems and international organisations.

Maritime acronyms become easier when you know what kind of thing they describe. A contract, an international convention and an organisation are different. Several may appear in the same joining email without meaning the same thing.
Use this compact guide to identify the subject, then ask for the actual document or requirement that applies to you.
Your employment paperwork
SEA — Seafarers' Employment Agreement. Your individual employment agreement. Check the parties, role, terms and any documents it incorporates.
CBA — Collective Bargaining Agreement. An agreement negotiated collectively that can set employment terms such as pay and working hours. Ask which CBA, if any, applies to your employment; a colleague's agreement may differ.
Keep the full title and version with your paperwork. “Covered by a CBA” is less useful than having the applicable agreement available to read.
Training, labour and safety
STCW — Standards of Training, Certification and Watchkeeping for Seafarers. The convention and code concern international training, competence and watchkeeping standards. “I need STCW” is incomplete shorthand: ask which course, certificate or endorsement is required for the role.
MLC — Maritime Labour Convention, 2006. An international labour convention addressing seafarers' working and living conditions. Whether and how a provision applies requires more than recognising the acronym.
SOLAS — Safety of Life at Sea. The international convention concerned with ship safety. It is not the name of a single training certificate.
ISM — International Safety Management. Usually encountered as the ISM Code, covering safe ship management and operation and pollution prevention.
SMS — Safety Management System. The documented system through which a company puts its safety-management arrangements into practice. Learn where your vessel's relevant procedures are available.
Organisations behind the letters
IMO — International Maritime Organization. The UN agency focused on shipping's safety, security and environmental performance.
ILO — International Labour Organization. The UN labour organisation associated with the MLC and other international labour standards.
An organisation's name in a document does not mean it issued your employment contract or personally approved a recruiter.
Ask for the noun after the acronym
If someone asks for “the STCW,” ask which certificate. If they mention “the agreement,” ask whether they mean your SEA or a CBA.
Save files with understandable names, such as the document title and issue date, instead of “final-final2.”
Takeaway: expand the letters, identify the document, and check the version. You do not need to memorise every maritime abbreviation to ask a precise question.
