Add Tankerman PIC, Radar Observer, GMDSS, ECDIS, BRM, ERM, and Leadership endorsements to any credential.

Specialty Endorsements

Specialty endorsements are the additions you stack onto a base credential to qualify for specific shipboard roles. You might hold an MCA OOW or a USCG Third Mate Unlimited license, but without a Radar Observer endorsement you cannot stand a bridge watch on any vessel carrying radar; without GMDSS you cannot operate the ship's radio; without Tankerman PIC you cannot supervise a cargo transfer on a tank vessel; without Advanced Firefighting you cannot stand a senior officer watch. MMCE.app treats specialty endorsements as first-class study tracks because the exams, while narrower than base-license exams, are often just as technical and carry the same pass-or-fail consequence for your career. A Chief Mate who lets an endorsement lapse can find themselves unable to sail until they re-sit the course and exam.

Exam systems by country

Most specialty endorsements are issued globally under STCW with national administration. The major endorsements tested worldwide include Tankerman PIC (Dangerous Liquid, Barge, Liquefied Gas), Lifeboatman / Proficiency in Survival Craft and Rescue Boats (PSCRB), Radar Observer (Unlimited / Inland / River), ARPA, GMDSS Operator (General Operator's Certificate and Restricted Operator's Certificate), Bridge Resource Management (BRM), Engine Room Resource Management (ERM), ECDIS, Advanced Firefighting, Medical Care Provider and Medical Person in Charge, and Leadership and Managerial Skills at the management level.

United States (USCG, NMC). Tankerman PIC exams are administered directly by the NMC. Radar Observer is a Coast Guard-approved course with a proctored exit exam. GMDSS is split between an FCC GROL/GMDSS exam and a USCG endorsement. BRM, ERM, ECDIS, Leadership at Operational Level, and Leadership at Management Level are all approved-course endorsements — no separate NMC exam, just the course completion certificate. Advanced Firefighting is STCW Reg VI/3 and requires refresher training every 5 years.

United Kingdom (MCA), Canada (TC), Australia (AMSA), New Zealand (MNZ), India (DG Shipping). Each jurisdiction operates a similar approved-course model for STCW-mandated endorsements. Local specialty endorsements (for example TC's Simulated Electronic Navigation Level 1/2, AMSA's Coxswain and Master Yacht endorsements, MCA's Dynamic Positioning Operator) follow the same pattern. Flag-of-convenience states (Panama, Liberia, Marshall Islands) accept most STCW-compliant endorsements from white-list countries without re-examination.

Typical exam structure

Tankerman PIC Dangerous Liquid (USCG). 70 questions, 3 hours 30 minutes, 70% pass. Material covers 46 CFR Subchapter D and O, the chemistry of petroleum products, tank-vessel cargo operations, inert gas systems, and pollution prevention.

Tankerman PIC Liquefied Gas (USCG). Separate 70-question exam covering 46 CFR Subchapter I-A, LNG and LPG cargo handling, cryogenic systems, and the IGC Code. LNG carrier billets are among the highest-paid merchant marine jobs and the exam reflects the technical depth.

Radar Observer (USCG). Approved course exit exam administered by the training facility. Written portion plus a practical plotting exercise on a radar simulator. Unlimited version is universally held; Inland and River are less common. Renewal every 5 years requires refresher training or proof of recent radar watchstanding.

GMDSS General Operator's Certificate. FCC Element 7 exam (75-100 questions) covering GMDSS equipment, SOLAS Chapter IV, Inmarsat-C, DSC procedures, NAVTEX, and EPIRB/SART operation. A separate USCG endorsement (Element 1/Element 2 equivalent) is then issued. The FCC also offers a GROL (General Radiotelephone Operator License) which is the US baseline radio operator credential.

ECDIS. 40-hour approved course with practical and written assessments, typically 70% pass. Type-specific ECDIS training (Furuno, JRC, Transas, Sperry, Kelvin Hughes) is a separate, employer-specific requirement on top of generic ECDIS.

BRM and ERM. 3-5 day approved courses with scenario-based assessments rather than traditional exams. The 2010 Manila Amendments made BRM/ERM mandatory for all officers.

Advanced Firefighting. STCW Regulation VI/3, approved course with written exam and practical demonstrations including use of SCBA, fire party leader tactics, and post-fire investigation.

Leadership and Managerial Skills (Management Level). STCW Regulation II/2 or III/2 approved course required for Chief Mate / Master / Chief Engineer upgrades.

Typical sea service / prerequisites

Tankerman PIC: 90 days on a tank vessel in the appropriate category, 10 supervised cargo transfers, and completion of an approved tankerman course. The PIC Barge variant has similar requirements tailored to tank barges. Liquefied Gas requires additional LNG or LPG course work.

Radar Observer Unlimited: no sea-service prerequisite, just completion of the approved course. Must be renewed every 5 years.

GMDSS: no sea service prerequisite for the FCC exam, but the USCG GMDSS Operator endorsement requires 6 months of service or successful completion of a GMDSS simulator course.

BRM / ERM / ECDIS / Leadership: typically required before the next officer-level upgrade. ECDIS is generic, but many companies require type-specific ECDIS training for each bridge system installed on their vessels.

Advanced Firefighting: prior completion of STCW Basic Training (Basic Fire Fighting). Required for Chief Mate, Master, Second Engineer, and Chief Engineer upgrades.

Core subject matter

Tankerman PIC. Cargo properties (flash point, vapor density, reactivity), tank vessel types (single-hull, double-hull, IMO Type I/II/III for chemicals), cargo transfer procedures, inert gas generation and distribution, tank cleaning, gas freeing and safe entry, the Oil Record Book, the Declaration of Inspection (DOI), and 33 CFR 155/156 transfer procedures. Vapor control system (VCS) requirements for US ports are a specific sub-topic.

Radar Observer. Radar theory (pulse, PRF, beam width, range and bearing resolution), target tracking, relative vs. true motion, plotting on a maneuvering board or radar simulator, CPA/TCPA calculation, ARPA integration, and the use of radar as a collision-avoidance aid under COLREGS Rule 7 and Rule 19.

GMDSS. Sea areas A1/A2/A3/A4, distress alerting via DSC on VHF Channel 70 and MF/HF, Inmarsat-C distress messaging, search and rescue transponders (SART) and AIS-SART, Emergency Position-Indicating Radio Beacons (EPIRB, 406 MHz), NAVTEX broadcast frequencies and message types, and SafetyNET enhanced group calling. The transition to Iridium-based GMDSS service under the 2020 modernization adds a layer of updated content.

ECDIS. ENC (Electronic Navigational Chart) vs. RNC, CATZOC data quality, route planning and monitoring, safety contour and safety depth settings, look-ahead sector, UKHO and NOAA chart catalogs, SOLAS Chapter V carriage requirements, and the specific difference between ECDIS (type-approved) and ECS (not type-approved). Back-up arrangements (second type-approved ECDIS vs. paper charts) are a common exam question.

BRM / ERM. Situational awareness, challenge and response communication, assertiveness, fatigue management, workload management, leadership styles, the "sterile cockpit" concept adapted to bridge watches, and just-culture error reporting. Case studies of real incidents (Herald of Free Enterprise, Exxon Valdez, Costa Concordia) recur in course materials.

Advanced Firefighting. Fire tetrahedron, classes of fire, fixed fire-fighting systems (CO2, foam, water mist, high-fog), SCBA, fire party organization, command post procedures, and search-and-rescue inside a burning compartment.

Leadership and Managerial Skills. ISM Code requirements for the master and chief engineer, personnel management, crew training and assessment, budgeting, safety culture, and port-state control inspection response. MLC 2006 crew welfare provisions are also covered.

Common pitfalls

Tankerman PIC candidates underestimate the volume of memorization (pump flow rates, inert gas oxygen content limits, tank cleaning sequences) and overrely on their shipboard experience. Radar Observer candidates fail the plotting portion because they cannot quickly and accurately determine CPA/TCPA under time pressure. GMDSS candidates fail Element 7 because they treat it as a radio-operator test and neglect the SOLAS Chapter IV regulatory content. ECDIS candidates pass the course but fail in practice when their ship's specific ECDIS brand behaves differently from the simulator; type-specific training is a frequent audit finding. BRM and ERM are often viewed as "soft skill" courses and attendees disengage, only to discover the written assessment is rigorous. Advanced Firefighting candidates fail the practical when they are not physically fit for SCBA work. Leadership at Management Level candidates often submit written case studies that do not meet the course assessment criteria.

How to study with MMCE.app

Specialty endorsements always sit on top of a base credential. The officers and ratings hubs describe the base licenses specialties attach to. The conventions hub covers the SOLAS, STCW, and MARPOL material that underpins every specialty endorsement — for example the LSA Code underpins Proficiency in Survival Craft, SOLAS Chapter IV underpins GMDSS, and 46 CFR Subchapter D underpins Tankerman PIC. Naval sailors transitioning to merchant marine work often pick up Radar Observer and GMDSS first because the technical content overlaps with their Navy training.
