The Isis Lock is close to Sheepwash Channel , just to the south and linking with the River Thames to the west. To the west of the lock are Rewley Road , the Cherwell Valley Line , and the Cotswold Line , just north of Oxford railway station . To

92-496: A United Nations agency, and the Nautical Institute seek improved international standards for mariners. One's 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 quick turnaround of many modern ships, spending only

138-494: A bracket, or a shaft, or something extraordinarily complex, such as aerospace components accurate to 5 micrometres. Good machinists are highly sought after and respected skilled trades persons and are generally well-paid. In utility, medical, and military use companies, experienced machinists can earn over $ 100 000 per year. Some titles reflect further development of machinist skills such as tool and die maker , patternmaker , mold maker , programmer , and operator . A machinist

184-635: 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 Labor Organization,

230-567: A large variety of shapes, and whose use in the workflow depends on the part to be machined. CNC machines are becoming the standard due to their speed, precision, flexibility, repeatability, and reduced downtime while changing jobs. Production runs consisting of large numbers of parts are more cost effective and commonly referred to as production work in the trade. Conversely, small production runs are sometimes referred to as prototype or jobbing work. Production engineers use blueprints and engineering drawings to produce detailed specifications of

276-633: A lifeboat and later went on to write the James Bond movies Never Say Never Again and Thunderball . Members of the American Beat Movement Allen Ginsberg , Jack Kerouac , Bob Kaufman , and Herbert Huncke were all Merchant Mariners. It is perhaps not surprising that the writers of Moby Dick , The American Practical Navigator , and Two Years Before the Mast were Merchant Mariners. It might be surprising that

322-410: A mariner's off-duty time at sea is largely a solitary affair, pursuing hobbies, reading, writing letters, and sleeping. Internet accessibility is fast coming to the sea with the advent of cheap satellite communication, mainly from Inmarsat . The availability of affordable roaming SIM cards with online top-up facilities have also contributed to improved connection with friends and family at home. Erik

368-496: A matter of hours in port, limits a seafarer's free-time ashore. Moreover, some seafarers entering U.S. ports from a watch list of 25 countries deemed high-risk 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

414-497: A military navy or civilian merchant navy , as a sport or recreationally. In a navy , there may be further distinctions: sailor may refer to any member of the navy even if they are based on land; while seaman may refer to a specific enlisted rank . Seafarers hold a variety of professions and ranks, each of which carries unique responsibilities which are integral to the successful operation of an ocean-going vessel. A ship's crew can generally be divided into four main categories:

460-413: A much safer position. Most newer vessels are air conditioned, soundproofed from noisy machinery, and equipped with comfortable living quarters. These amenities have helped ease the sometimes difficult circumstances of long periods away from home. Also, modern communications such as email, instant messaging and social media platforms link modern mariners to their families. Nevertheless, some mariners dislike

506-426: A saw cut length of stock or a casting . Producing a part will often require several steps and more than one machine tool. Each machine tool plays a specific role in cutting away excess material. When large numbers of parts are needed, production planning is required to plan the most logical workflow through a series of machines. Computer numerical controlled (CNC) machines are computer-driven tools that can machine

552-868: A ship includes: American ships also carry a qualified member of the engine department . Other possible positions include motorman, machinist , electrician , refrigeration engineer and tankerman. A typical steward's department for a cargo ship is 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. The chief steward also plans menus, compiles supply, overtime, and cost control records. The steward may requisition or purchase stores and equipment. Galley's roles may include baking. A chief steward's duties may overlap with those of

598-491: A thousandth of an inch – or 0.0025 mm) for specialty operations. A machinist deals with all facets of shaping, cutting and some aspects of forming metal, although forming is typically a separate trade. The operations most commonly performed by machinists are milling , drilling , turning , and grinding . There are other more specialized operations that a machinist will less frequently be called upon to perform such as honing , keyseating , lapping , and polishing , to name

644-412: 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

690-596: A working knowledge of the proper parameters required for successfully utilizing the various tools commonly used in machining operations. CNC (computer numerical control) is the modern manufacturing method in which machinist use a form of programming called G-code to make components for a wide variety of industries. CNC programming is a highly skilled position. Programmers are usually machinist as well. A CNC programmer creates programs using software called CAM (computer aided manufacturing). The programmer must be proficient in math, speeds and feeds, machine tooling, work holding, and

736-415: Is another regular task. Engineering staff is required to have training in firefighting and first aid. Additional duties include maintaining the ship's boats and performing other nautical tasks. Engineers play a key role in cargo loading/discharging gear and safety systems, though the specific cargo discharge function remains the responsibility of deck officers and deck workers. A common engineering crew for

782-530: Is one who is called on to fix a problem with a part or to create a new one using metals, plastics, or rarely, wood. Depending on the company, a machinist can be any or all of the titles listed above. Other related fields include Millwrights , quality assurance , and mechanical engineers . In Australia, a related profession is a fitter and turner . A fitter and turner is the tradesperson who fits, assembles, grinds and shapes metal parts and subassemblies to fabricate production machines and other equipment. Under

828-650: The steward's assistant , the chief cook , and other Steward's department crewmembers. A person in the United States Merchant Marine has to have a Merchant Mariner's Document issued by the United States Coast Guard in order to serve as a chief steward. All chief cooks who sail internationally are similarly documented by their respective countries because of international conventions and agreements. The only time that steward department staff are charged with duties outside

874-508: The Oxford Canal Company's Worcester Street wharves. Isis Lock was rebuilt as a narrow lock in 1844. Boatmen The profession of the sailor is old, and the term sailor has its etymological roots in a time when sailing ships were the main mode of transport at sea, but it now refers to the personnel of all watercraft regardless of the mode of transport, and encompasses people who operate ships professionally, be it for

920-802: The Red and his son Leif Erikson were the first notable mariners known to sail in a primitive, partly man powered vessel across the Arctic and the North Atlantic Ocean. Barbarossa Hayrettin Pasha (Turkish: Barbaros Hayrettin Paşa or Hızır Hayrettin Paşa; also Hızır Reis before being promoted to the rank of Pasha and becoming the Kaptan-ı Derya (Fleet Admiral) of the Ottoman Navy) (c. 1478 – 4 July 1546)

966-553: The United States Coast Guard. Pilots are also merchant marine officers and are licensed by the Coast Guard. Mariners spend extended periods at sea. Most deep-sea mariners are hired for one or more voyages that last for several months. There is no job security after that. The length of time between voyages varies by job availability and personal preference. The rate of unionization for these workers in

1012-524: The United States is about 36 percent, much higher than the average for all occupations. Consequently, merchant marine officers and seamen, both veterans and beginners, are hired for voyages through union hiring halls or directly by shipping companies. Hiring halls fill jobs by the length of time the person has been registered at the hall and by their union seniority. Hiring halls typically are found in major seaports. At sea, on larger vessels members of

1058-792: The Victoria Cross and the Medal of Honor . American merchant seamen have won the Medal of Honor in the Korean War and Vietnam War , and one went on to become the "Father of the American Navy." One does not have to look far to find merchant seamen who became war heroes in Scotland , France , New Zealand , Peru , or Denmark . Since World War II, a number of merchant seamen have become notorious criminals. American William Colepaugh

1104-758: The city of Sydney, Australia . Merchant mariner Douglass North went from seaman to navigator to winner of the 1993 Nobel Prize in Economics. Jimmy Carter went on to become the 39th president of the United States after service in the US Navy. Members of the British Merchant Navy have won the Distinguished Service Cross and have had careers taking them from 'Deck Boy Peter' to Air Marshal Sir Beresford Peter Torrington Horsley KCB, CBE, LVO, AFC . Canadian merchant seamen have won

1150-776: The deck department usually stand watch for four hours and are off for eight hours, seven days a week. Mariners work in all weather conditions. Working in damp and cold conditions often is inevitable, although ships try to avoid severe storms while at sea. It is uncommon for modern vessels to suffer disasters such as fire, explosion, or a sinking. Yet workers face the possibility of having to abandon ship on short notice if it collides with other vessels or runs aground. Mariners also risk injury or death from falling overboard and from hazards associated with working with machinery, heavy loads, and dangerous cargo. However, modern safety management procedures, advanced emergency communications, and effective international rescue systems place modern mariners in

1196-400: The deck department, the engineering department, the steward's department, and others. Officer positions in the deck department include but are 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 . With some variation, the chief mate is most often charged with

1242-442: The different ways various materials react to stress and heat in the machining process. The machine trade is an extremely broad field with a wide variety of workplaces, job duties, and types of work. Most machinists work in machine shops and factories where they operate machinery that produce precision component parts. In general, the occupation is exacting, and requires extensive knowledge of the tools and processes in order to achieve

1288-400: The duties of cargo mate. Second Mates are charged with being the medical officer in case of a medical emergency. All three mates each do four-hour morning and afternoon shifts on the bridge, when underway at sea. A common deck crew for a ship includes: A ship's engineering department consists of the members of a ship's crew that operates and maintains the propulsion and other systems on board

1334-549: The east over the Oxford Canal are the grounds of Worcester College , one of the colleges of Oxford University . There is a winding hole for boats to turn on the Oxford Canal just to the north of the lock. In central Oxford, the Oxford Canal and the River Thames were originally linked by a flash lock at Hythe Bridge . In 1795–97, David Harris replaced it with Isis Lock, a broad lock to allow Thames barges in and out of

1380-424: The long periods away from home and the confinement aboard ship. They consequently leave the profession. Professional mariners live on the margins of society, with much of their life spent beyond the reach of land. They face cramped, stark, noisy, and 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. Seagoing adventure and

1426-596: The machinist title are other specialty titles that refer to specific skills that may be more highly developed to meet the needs of a particular job position, such as fitter (assembles parts), turning hand , mill hand , and grinder . A machinist is usually called upon when a part needs to be produced from a stock material by cutting. Such a part may be unique or may be needed in the thousands. The part could be anything made from metal or plastic, though machined parts are usually ones that require high precision and cannot be produced by other means. Machinists generally start with

1472-701: The meaning of the term suggests the need for specialized handling and/or tooling to machine them effectively. While the foregoing were primarily the materials that a machinist would be cutting, the cutters that the machinist uses must be harder and tougher than the materials to be cut. The materials in the cutters a machinist uses are most commonly high-speed steel , tungsten carbide , ceramics , Borazon , and diamond . Machinists usually work to very small tolerances , usually within 0.010" or 0.25 mm (more commonly expressed as ±0.005" (Plus or minus five thousandths of an inch) or ±0.13 mm), and sometimes at tolerances as low as +/-0.0001" (plus or minus one tenth of

1518-575: The most common materials. Materials that machinists work with occasionally are plastics , rubber , glass , and wood products. Rarely, machinists also work with exotic and refractory metals . The term exotic metals is a general term describing out of the ordinary, rare or special purpose metals. A synonym might be space-age. A list of exotic metals might include, but is not limited to, titanium , beryllium , vanadium, chromium , molybdenum and tungsten , as well as special high-temperature metal alloys like Inconel or Hastelloy ( superalloys ). Very often

1564-456: The most part are strangers takes getting used to. At the same time, there is an opportunity to meet people from a wide range of 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,

1610-471: The part, especially its geometry (shape), then decide on a strategy to make it. Machine tools are then configured by the machinist and production commences. The machinist works with the quality department to ensure the specifications are maintained in the finished product. Large commercial organizations often staff machinists on site in a maintenance mode to ensure continuing operations of the production machinery. Such machinists can often make replacement parts

1656-872: The same day. Because of this, the labor cost for this role are significantly lower than costs involved with production shutdowns. Additive machining means 3D printing to create industrial components, prototypes, tooling, and end-use production parts. Additive machining comes into its own in the manufacturing of very small intricate parts, which could not be produced through any other manufacturing process. There are several processes in additive manufacturing which include direct metal deposition: electron beam melting, fused filament fabrication, select laser sintering, and variations of them. The most common materials that machinists make parts from are steel , aluminium , brass , copper , and various alloys of these materials. Other less common materials such as vanadium , zinc , lead , or manganese are often used as alloying elements for

1702-499: The steward department is during the execution of the fire and boat drill. Various types of staff officer positions may exist on board a ship, including junior assistant purser, senior assistant purser, purser , chief purser, medical doctor , professional nurse , marine physician assistant, and hospital corpsman . In the USA these jobs are considered administrative positions and are therefore regulated by Certificates of Registry issued by

1748-443: The tight tolerances and surface finishes that these parts specify. Many machinists make mass-produced parts using highly automated computer numerical control machines which are common today, but still require such professionals to set up and calibrate the machines. Other more specialised machinists produce custom-made parts for prototyping, repair, or research. A machinist may work on manufacturing something relatively simple like

1794-401: The vessel. Marine engineering staff also deal with the "hotel" facilities on board, notably the sewage , lighting, air conditioning and water systems. Engineering staff manages bulk fuel transfers, from a fuel-supply barge in port. When underway at sea, the second and third engineers will often be occupied with oil transfers from storage tanks, to active working tanks. Cleaning of oil purifiers

1840-503: The visual arts. French pilot's assistant Paul Gauguin later became a leading post-impressionist painter and pioneered modern art's synthetist style. American seaman Haskell Wexler later won two Academy Awards , the latter for a biography of his shipmate Woody Guthrie . British Merchant Navy member Ken Russell later directed films such as Tommy , Altered States and The Lair of the White Worm . Merchant seaman Johnny Craig

1886-449: The word "sailor" has come to mean many things.
