Ship transport is watercraft carrying people (passengers) or goods (cargo). Sea transport has been the largest carrier of freight throughout recorded history. Although the importance of sea travel for passengers has decreased due to aviation, it is effective for short trips and pleasure cruises. Transport by water is cheaper than transport by air.
Ship transport can be over any distance by boat, ship, sailboat or barge, over oceans and lakes, through canals or along rivers. Shipping may be for commerce, recreation or the military. Virtually any material that can be moved, can be moved by water, however water transport becomes impractical when material delivery is highly time-critical. "General cargo" is goods packaged in boxes, cases, pallets, and barrels. Containerization revolutionized ship transport in the 1960s. When a cargo is carried in more than one mode, it is intermodal or co-modal.At the age of 15 you can work with Ship transport.
Merchant shipping
A nation's shipping fleet (merchant navy, merchant marine, merchant fleet) consists of the ships operated by civilian crews to transport passengers or cargo. Professionals are merchant seaman, merchant sailor, and merchant mariner, or simply seaman, sailor, or mariner. The terms "seaman" or "sailor" may refer to a member of a country's navy.
According to the 2005 CIA World Factbook, the world total number of merchant ships of 1,000 Gross Register Tons or over was 30,936. Statistics for individual countries are available at the List of merchant marine capacity by country.
Professional mariners
A ship's complement can be divided into four categories: the deck department, the engineering department, the steward's department, and other.
Deck department
Officer positions in the deck department include but not limited to: Master and his Chief, Second, and Third officers. The official classifications for unlicensed members of the deck department are Able Seaman and Ordinary Seaman.
A common deck crew for a ship includes:
- (1) Chief Officer/Chief Mate
- (1) Second Officer /Second Mate
- (1) Third Officer / Third Mate
- (1) Boatswain
- (2-6) Able Seamen
- (0-2) Ordinary Seamen
A deck cadet is person who is carrying out mandatory seatime to achieve their officer of the watch certificate. Their time onboard is spent learning the operations and tasks of everyday life on a merchant vessel.
Engineering department
A ship's engineering department consists of the members of a ship's crew that operate and maintain the propulsion and other systems on board the vessel. Marine Engineering staff also deal with the "Hotel" facilities on board, notably the sewage, lighting, air conditioning and water systems. They deal with bulk fuel transfers, and require training in firefighting and first aid, as well as in dealing with the ship's boats and other nautical tasks- especially with cargo loading/discharging gear and safety systems, though the specific cargo discharge function remains the responsibility of deck officers and deck workers. On LPG and LNG tankers however, a cargo engineer works with the deck department during cargo operations, as well as being a watchkeeping engineer.
A common Engineering crew for a ship includes:
- (1) Chief Engineer
- (1) Second Engineer / First Assistant Engineer
- (1) Third Engineer / Second Assistant Engineer
- (1-2) Fourth Engineer / Third Assistant Engineer
- (0-2) Fifth Engineer / Junior Engineer
- (1-3) Oiler (unlicensed qualified rating)
- (0-3) Greaser/s (unlicensed qualified rating)
- (1-5) Entry-level rating (such as Wiper (occupation), Utilityman, etc.)
Many American ships also carry a Qualified Member of the Engine Department. Other possible positions include Motorman, Machinist, Electrician, Refrigeration Engineer, and Tankerman. Engine Cadets are trainee engineers who are completing sea time necessary before they can obtain a watchkeeping license.
Steward's department
A typical Steward's department for a cargo ship would be composed of a Chief Steward, a Chief Cook, and a Steward's Assistant. All three positions are typically filled by unlicensed personnel.
The chief steward directs, instructs, and assigns personnel performing such functions as preparing and serving meals; cleaning and maintaining officers' quarters and steward department areas; and receiving, issuing, and inventorying stores.
On large passenger vessels, the Catering Department is headed by the Chief Purser and managed by assistant pursers. Although they enjoy the benefits of having officer rank, they generally progress through the ranks to become pursers. Under the pursers are the department heads - such as chief cook, head waiter, head barman etc. They are responsible for the administration of their own areas.
The chief steward also plans menus; compiles supply, overtime, and cost control records. May requisition or purchase stores and equipment. May bake bread, rolls, cakes, pies, and pastries.
A chief steward's duties may overlap with those of the Steward's Assistant, the Chief Cook, and other Steward's Department crewmembers.
In the United States Merchant Marine, in order to be occupied as a chief steward a person has to have a Merchant Mariner's Document issued by the United States Coast Guard. Because of international conventions and agreements, all chief cooks who sail internationally are similarly documented by their respective countries.
Other Departments
Staff officer positions on a ship, including Junior Assistant Purser, Senior Assistant Purser, Purser, Chief Purser, Medical Doctor, Professional Nurse, Marine Physician Assistant, and Hospital Corpsman, are considered administrative positions and are therefore regulated by Certificates of Registry issued by the United States Coast Guard. Pilots are also merchant marine officers and are licensed by the Coast Guard. Formerly, there was also a radio department, headed by a chief radio officer and supported by a number of radio officers. Since the introduction of GMDSS (Satellite communications) and the subsequent exemptions from carrying radio officers if the vessel is so equipped, this department has fallen away, although many ships do still carry specialist radio officers, particularly passenger vessels. Many radio officers became 'electro-technical officers', and transferred into the engineering department.
Life at sea
Mariners live much of their life spent beyond the reach of land. They face sometimes dangerous conditions at sea. Yet men and women still go to sea. For some, the attraction is a life unencumbered with the restraints of life ashore. Sea-going adventure and a chance to see the world also appeal to many seafarers. Whatever the calling, those who live and work at sea invariably confront social isolation.
Findings by the Seafarer's International Research Center indicate a leading cause of mariners leaving the industry is "almost invariably because they want to be with their families." U.S. merchant ships typically do not allow family members to accompany seafarers on voyages. Industry experts increasingly recognize isolation, stress, and fatigue as occupational hazards. Advocacy groups such as International Labour Organization, a United Nations agency, and the Nautical Institute are seeking improved international standards for mariners.
Ocean voyages are steeped in routine. Maritime tradition dictates that each day be divided into six four-hour periods. Three groups of watchkeepers from the engine and deck departments work four hours on then have eight hours off watchkeeping. However there are many overtime jobs to be done daily. This cycle repeats endlessly, 24 hours a day while the ship is at sea. Members of the steward department typically are day workers who put in at least eight-hour shifts. Operations at sea, including repairs, safeguarding against piracy, securing cargo, underway replenishment, and other duties provide opportunities for overtime work. Service aboard ships typically extends for months at a time, followed by protracted shore leave. However, some seamen secure jobs on ships they like and stay aboard for years.
In rare cases, veteran mariners choose never to go ashore when in port. Further, the often quick turnaround of many modern ships, spending only a matter of hours in port, limits a seafarer's free-time ashore. Moreover, some foreign seamen entering U.S. ports from a watchlist of 25 high-risk countries face restrictions on shore leave due to security concerns in a post 9/11 environment. However, shore leave restrictions while in U.S. ports impact American seamen as well. For example, the International Organization of Masters, Mates & Pilots notes a trend of U.S. shipping terminal operators restricting seamen from traveling from the ship to the terminal gate. Further, in cases where transit is allowed, special "security fees" are at times assessed.
Such restrictions on shore leave coupled with reduced time in port by many ships translate into longer periods at sea. Mariners report that extended periods at sea living and working with shipmates who for the most part are strangers takes getting used to. At the same time, there is an opportunity to meet people from other ethnic and cultural backgrounds. Recreational opportunities have improved aboard some U.S. ships, which may feature gyms and day rooms for watching movies, swapping sea stories, and other activities. And in some cases, especially tankers, it is made possible for a mariner to be accompanied by members of his family. However, a mariner’s off duty time is largely a solitary affair, pursuing hobbies, reading, writing letters, and sleeping.
On modern ocean going vessels, typically registered with a flag of convenience, life has changed immensely in the last 20 years. Most large vessels include a gym and often a swimming pool for use by the crew. Since the Exxon Valdez incident, the focus of leisure time activity has shifted from having officer and crew bars, to simply having lounge-style areas where officers or crew can sit to watch movies. With many companies now providing TVs and DVD players in cabins, and enforcing strict smoking policies, it is not surprising that the bar is now a much quieter place on most ships. In some instances games consoles are provided for the officers and crew. The officers enjoy a much higher standard of living on board ocean going vessels. Crews are generally poorly paid, poorly qualified and have to complete contracts of approx 9 months before returning home on leave. They often come from countries where the average industrial wage is still very low, such as the Philippines or India. Officers however, come from all over the world and it is not uncommon to mix the nationality of the officers on board ships. Officers are often the recipients of university degrees and have completed vast amounts of training in order to reach their rank. Officers benefit on board by having larger, more comfortable cabins, table service for their meals, etc. Contracts average at the 4 month mark for officers, with generous leave. Most Ocean going vessels now operate an Unmanned Engineroom System allowing engineers to work days only. The engine room is computer controlled by night, although the duty engineer will make inspections during unmanned operation. Engineers work in a hot, humid, noisy atmosphere. Communication in the engineroom is therefore by hand signals and lip-reading, and good teamwork often stands in place of any communication at all
