An ordinary seaman (OS) is a member of the deck department of a ship. The position is an apprenticeship to become an able seaman, and has been for centuries. In modern times, an OS is required to work on a ship for a specific amount of time, gaining what is referred to as "sea time". For centuries, the term ordinary seaman was used to refer to a seaman with between one and two years' experience at sea, who showed enough seamanship to be so rated by their captain. [1] Historically, in some navies and the merchant marine, a sailor with less experience was called a landsman. [2]
An OS is generally not required to stand watch, but must pass examinations on watchstanding skills such as performing lookout duty and being a helmsman. Thus an OS will often be found on a ship's bridge after working hours taking a turn at the ship's wheel or being familiarized with bridge equipment.
During the apprenticeship, an OS performs a variety of duties concerned with the operation and upkeep of deck department areas and equipment. These duties vary with the type of ship, the type of voyage, the number of crewmembers, the weather, the supervisor, and any number of other variables. However, in most cases, one can expect an ordinary seaman to clean, to perform maintenance, to work with deck equipment, and to undergo on-the-job-training under the supervision of senior deck department members.
As an ordinary seaman, one's duties may include the following:
Typical ordinary seaman duties | |
Illustration | Description |
---|---|
Scale, buff, and paint decks and superstructure. [3] A ship's metal structure is under constant attack from the corrosive properties of seawater. Members of a ship's deck department spend a good deal of time identifying and removing rust accumulations, and refinishing affected areas with sealants, primers, and paints to slow the oxidation process. | |
Sweep and wash deck. [3] Excess water and salt on deck can lead to slipping hazards as well as accelerated rusting of the deck and equipment affixed to it. Ordinary seamen often bear the brunt of the swabbing duties, and many look forward to earning their able seaman's ticket and being done with swabbing. | |
Splice wire and rope. [3] A proficiency at splicing, knotting, and marlinspike seamanship have identified able seamen for centuries. In the modern merchant fleets, a proficiency for this sort of work is a requirement for certification as an able seaman. Thus, during the period of apprenticeship, it is customary for the crew to challenge an ordinary seaman, and call upon the OS to demonstrate these marlinspike seamanship skills at regular intervals, under the guidance of senior members of the deck department. | |
Break out, rig, overhaul, and stow cargo-handling gear, stationary rigging, and running gear. [3] Depending on the type of ship, it may undergo routine cargo onloads and offloads. On container ships and roll-on roll-off ships, this requires the staging of large amounts of equipment, such as twist-locks, braces, ratchet-straps, tie-down rods, and so forth. These are generally kept in storage during a voyage, so that they won't get thrown by the ship's movement. Thus, the ordinary seaman is often called upon to move this sort of equipment from storage areas to cargo areas. | |
Secure cargo. [3] Cargo must be secured, or fastened to the ship, when it is brought on board. Depending on the type of ship and the type of cargo, this process may be nearly automatic or a very customized operation. During a voyage, cargo is regularly checked to look for wear and tear, broken or compromised securements, shifting, or any other sort of noncompliance. If irregularities are found, the deck crew must respond by resecuring the cargo. Finally, near the end of the voyage, securements may be exercised or loosened to avoid problems with discharge. | |
Launch and recover boats. [3] One of the proficiencies that must be demonstrated to pass the examination for able seaman is a proficiency in all aspects of work with lifeboats. International regulations require merchant ships to run regular lifeboat drills, and the ordinary seaman is customarily given a variety of duties during these drills to become familiar and comfortable with launching, commanding, and retrieving a lifeboat. |
On specialized vessels, an OS may have unique duties. For example, on research vessels, an OS may rig and operate hydrographic and other specialty winches; handle and stow oceanographic explosives; and stage and stow beach support equipment.
The next step on the career ladder for the ordinary seaman is to become an able seaman. This advancement is based on a number of factors laid out in the Code of Federal Regulations.
The Code of Federal Regulations establishes in 46 CFR 12.05 [4] four categories of able seaman for the United States Merchant Marine:
Time served in certain training programs and school ships may be substituted for the time of service listed above. Special certificates of service are available for Able Seaman, Great Lakes—18 months service; Able Seaman, Any waters—12 months; Able Seaman, Tugs and towboats—any waters; Able Seaman, Bays and sounds—12 months, vessels 500 gross tons or less not carrying passengers; and Able Seaman, Seagoing barges—12 months.
For the United States Merchant Marine, the Code of Federal Regulations establishes in 46 CFR 12.05 [4] examination requirements for the certification of able seamen, which includes:
Maritime transport or more generally waterborne transport, is the transport of people (passengers) or goods (cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air or ground, but significantly slower for longer distances. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD in 2020.
Seamanship is the art, knowledge and competence of operating a ship, boat or other craft on water. The Oxford Dictionary states that seamanship is "The skill, techniques, or practice of handling a ship or boat at sea."
The United States Merchant Marine is an organization composed of United States civilian mariners and U.S. civilian and federally owned merchant vessels. Both the civilian mariners and the merchant vessels are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports domestic and international cargo and passengers during peacetime, and operate and maintain deep-sea merchant ships, tugboats, towboats, ferries, dredges, excursion vessels, charter boats and other waterborne craft on the oceans, the Great Lakes, rivers, canals, harbors, and other waterways. In times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military.
A boatswain, bo's'n, bos'n, or bosun, also known as a deck boss, or a qualified member of the deck department, is the most senior rate of the deck department and is responsible for the components of a ship's hull. The boatswain supervises the other members of the ship's deck department, and typically is not a watchstander, except on vessels with small crews. Additional duties vary depending upon ship, crew, and circumstances.
A chief mate (C/M) or chief officer, usually also synonymous with the first mate or first officer, is a licensed mariner and head of the deck department of a merchant ship. The chief mate is customarily a watchstander and is in charge of the ship's cargo and deck crew. The actual title used will vary by ship's employment, by type of ship, by nationality, and by trade: for instance, chief mate is not usually used in the Commonwealth, although chief officer and first mate are; on passenger ships, the first officer may be a separate position from that of the chief officer that is junior to the latter.
A second mate or second officer (2/O) is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competence, by an authorised governing state of the International Maritime Organization (IMO). The second mate is the third in command and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations.
A third mate (3/M) or third officer is a licensed member of the deck department of a merchant ship. The third mate is a watchstander and customarily the ship's safety officer and fourth-in-command. The position is junior to a second mate. Other duties vary depending on the type of ship, its crewing, and other factors.
Under the Seafarers' Identity Documents Convention, 1958, countries with a merchant navy (also called a merchant marine) require identifying credentials for their mariners. The Merchant Mariner's Document (MMD) or Z-card in the United States, and the Ordinary Seaman's Certificate in the United Kingdom are examples of these credentials.
Seafaring is a tradition that encompasses a variety of professions and ranks. Each of these roles carries unique responsibilities that are integral to the successful operation of a seafaring vessel. A ship's crew can generally be divided into four main categories: the deck department, the engineering department, the steward's department, and other. The reasoning behind this is that a ship's bridge, filled with sophisticated navigational equipment, requires skills differing from those used on deck operations – such as berthing, cargo and/or military devices – which in turn requires skills different from those used in a ship's engine room and propulsion, and so on.
A maritime pilot, marine pilot, harbor pilot, port pilot, ship pilot, or simply pilot, is a mariner who has specific knowledge of an often dangerous or congested waterway, such as harbors or river mouths. Maritime pilots know local details such as depth, currents, and hazards. They board and temporarily join the crew to safely guide the ship's passage, so they must also have expertise in handling ships of all types and sizes. Obtaining the title "maritime pilot" requires being licensed or authorised by a recognised pilotage authority.
A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board. He is the one and only official authority on board. He represents the ship police and furthermore he is the unique tutor for the order and the discipline for crew and for all people present on the ship.
An oiler is a worker whose main job is to oil machinery. In previous eras there were oiler positions in various industries, including maritime work, railroading, steelmaking, and mining. Today most such positions have been eliminated through technological change; lubrication tends to require less human intervention, so that workers seldom have oiling as a principal duty. In the days of ubiquitous plain bearings, oiling was often a job description in and of itself.
An able seaman (AB) is a seaman and member of the deck department of a merchant ship with more than two years' experience at sea and considered "well acquainted with his duty". An AB may work as a watchstander, a day worker, or a combination of these roles. Once a sufficient amount of sea time is acquired, then the AB can apply to take a series of courses/examinations to become certified as an officer.
Ordinary seaman is a military rank used in naval forces.
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety.
A master mariner is a licensed mariner who holds the highest grade of seafarer qualification; namely, an unlimited master's license. Such a license is labelled unlimited because it has no limits on the tonnage, power, or geographic location of the vessel that the holder of the license is allowed to serve upon. A master mariner would therefore be allowed to serve as the master of a merchant ship of any size, of any type, operating anywhere in the world, and it reflects the highest level of professional qualification amongst mariners and deck officers.
Lifeboats played a crucial role during the sinking of the Titanic on 14–15 April 1912. The ship had 20 lifeboats that, in total, could accommodate 1,178 people, a little over half of the 2,209 on board the night it sank.
A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
Nautical operations refers to the crew operation of a ship. It is the term used in academic education to refer to the studies of this professional field. Nautical operations refers to all the operational procedures, specific roles of officers and crew members, and regular functions and technical processes, which together shape the structure and functions for the general operations of a ship.
