Who Is an Able Seaman

Seafarer is the umbrella word. It covers anyone who works aboard a ship under an employment agreement, from the cook to the master. Under the Maritime Labour Convention, 2006 (MLC 2006), a seafarer is any person employed, engaged or working in any capacity on board a ship.

An able seaman is a specific position in one department. A ship's crew is organised into departments: deck, engine, and service. An able seaman belongs to the deck department, working under the bosun and the officer of the watch.

Every able seaman is a seafarer, but not every seafarer is an able seaman. The engineer, the electro-technical officer, the cook and the steward are seafarers too, without holding the able seaman position.

One more overlap in wording causes confusion. In naval forces, "seaman" is a military rank. That has nothing to do with the merchant fleet, where the word names a position, not a rank, and the right to hold it comes from a certificate, not an order of appointment.

Watchkeeping is the core of the job. An able seaman stands on the bridge to assist the officer of the watch and covers three main tasks.

Look-out. Visual and aural look-out is a duty written directly into the international rules for preventing collisions at sea. Spot a light, a vessel, a floating object, and it gets reported to the officer of the watch.

Steering. Switching from autopilot to manual steering, holding a course on command, working through crossing situations, narrow channels and canal transits.

Rounds and reports. Checking the ship along a set route: closures, cargo securing, alarm systems.

In port the watch changes shape. Gangway duty: controlling who comes aboard, watching mooring lines and draft, monitoring cargo operations.

Shipboard maintenance is the other half of the job, and by hours it often outweighs watchkeeping.

Mooring operations: running and receiving mooring lines, working the windlass and mooring winches, anchoring. Mooring is the most injury-prone deck operation on a merchant ship, and most serious cases trace back to parted lines and snap-back zones.

Hull and deck upkeep: chipping rust, cleaning, priming, painting. The dull, unending part of the job that rarely makes it into career descriptions, yet takes up most of the daylight hours on a passage.

Cargo gear work: preparing holds, opening and closing hatch covers, securing cargo, taking measurements.

Emergency stations: an able seaman's place at boat and fire stations, working hoses and nozzles, launching life-saving equipment, actions for a man-overboard alarm.

Ukraine's licensing system splits the able seaman position into two national qualifications, and international practice maps them onto two STCW Convention classes: ordinary seafarer, a rating forming part of a navigational watch under regulation II/4, and able seafarer deck under regulation II/5.

The ordinary seafarer qualification is the entry point. Regulation II/4 covers a rating who forms part of a navigational watch. Minimum age is 16. The path in requires either approved seagoing service that includes no less than six months of training and experience, or special training, before joining a ship or on board, combined with no less than two months of approved seagoing service.

The able seafarer deck qualification is the higher, certified grade under regulation II/5. Minimum age is 18. It requires meeting the standard set for a rating forming part of a navigational watch, plus approved seagoing service in the deck department: no less than 18 months, or no less than 12 months given approved training.

The gap between the two goes past the paperwork. An able seafarer deck is expected to work independently: handling rigging, taking on more demanding operations, standing wheel watches in difficult conditions more often, and typically earning more. The bosun, the senior rating in the deck department, comes up through this route.

Ukraine's training programmes follow the same logic. Admission to the able seafarer deck course requires an existing ordinary seafarer qualification, no less than twelve months of seagoing service in the deck department, complete general secondary education, and an age of 18 or over by the end of training.

The paperwork comes in three layers.

Personal documents: a seafarer's identity document, a seaman's discharge book, an international passport, a medical fitness certificate for work aboard ship.

A certificate of competency for the position: the document that grants the right to hold the able seaman position on the crew list.

Mandatory training certificates under STCW Convention Chapter VI, required of every crew member without exception: safety familiarization training, survival craft and rescue boats, first aid, fire fighting. Beyond these, further certificates get added depending on ship type, tanker operations among them.

The certificates carry a limited validity period and need periodic renewal. An expired basic package is the most common reason a seafarer gets turned down for a voyage, even when the certificate of competency itself is current.

The route starts with an ordinary seafarer course: theory, practical sessions, drills on simulators and training grounds.

Assessment follows the competence standard set in the STCW Code. Examiners check whether a candidate can perform an operation, not recite theory: hold a course, report a sighted object correctly, put on a lifejacket and act on an alarm, handle mooring lines.

Answer keys to qualification tests are not a legal product. Materials sold as such are, at best, out of date, and at worst lead to a certificate being cancelled. No training centre can guarantee an exam pass. That decision belongs to the examination board.

In Ukraine, the programme runs three months, delivered online through an interactive platform or in person. No prior seagoing service is required at entry: candidates need complete general secondary education, medical fitness for work on water transport, and an age of at least 18 by the end of training. Graduates receive a state-issued certificate of qualification, and the record is entered into Ukraine's Unified State Electronic Database on Education (EDEBO), the national register for education and qualification documents.

The first step up is able seafarer deck, once the required seagoing service is logged. After that comes bosun, the senior rating in the deck department.

A separate branch leads into the officer ranks. That route runs through maritime education under a navigation officer programme: seagoing service as an able seaman on its own does not produce an officer of the watch certificate. Many follow both paths at once, working as an able seaman while studying by distance learning.

Adjacent specialisations exist too: cargo work on specialised tonnage, deck crane operation, training tied to a specific ship type. The certificate package differs between a tanker, a bulker and a gas carrier, and that gets worked out before enrolling in a course, not after.
