Marine engineering

:''This article largely pertains to design engineering. For the operating engineer, see marine engineer.''
Marine engineering often refers to the engineering of boats, ships, oil rigs and any other marine vessel or structure, but also encompasses oceanographic engineering. Specifically, marine engineering is the discipline of applying engineering sciences, and can include mechanical engineering, electrical engineering, electronic engineering, and computer science, to the development, design, operation and maintenance of watercraft propulsion and also on-board systems and oceanographic technology, not limited to just power and propulsion plants, machinery, piping, automation and control systems etc. for marine vehicles of any kind like surface ships, submarines etc..
The purely mechanical ship operation aspect of marine engineering has some relationship with naval architects. However, whereas naval architects are concerned with the overall design of the ship and its propulsion through the water, marine engineers are focused towards the main propulsion plant, the powering and mechanization aspects of the ship functions such as steering, anchoring, cargo handling, heating, ventilation, air conditioning, electrical power generation and electrical power distribution, interior and exterior communication, and other related requirements. In some cases, the responsibilities of each industry collide and is not specific to either field. Propellers are examples of one of these types of responsibilities. For naval architects a propeller is a hydrodynamic device. For marine engineers a propeller acts similarly to a pump. Hull vibration, excited by the propeller, is another such area. Noise control and shock hardening must be the joint responsibility of both the naval architect and the marine engineer. In fact, most issues caused by machinery are responsibilities in general.〔Kane, J.R. (1971). Marine Engineering. New York: SNAME (page 1)〕
Not all marine engineering is concerned with moving vessels. Offshore construction, also called offshore engineering, ocean engineering or maritime engineering, is concerned with the technical design of fixed and floating marine structures, such as oil platforms and offshore wind farms.
Oceanographic Engineering is concerned with mechanical, electrical, and electronic, and computing technology deployed to support oceanography, and also falls under the umbrella of marine engineering, especially in Britain, where it is covered by the same professional organisation, the IMarEST.
==History of Marine Engineering==
Archimedes is traditionally regarded as the first marine engineer, having developed a number of marine engineering systems in antiquity. Modern Marine Engineering dates back to the beginning of the Industrial Revolution (early 1700s). In 1712 Thomas Newcomen, a blacksmith, created a steam powered engine to pump water out of mines. In 1807 Robert Fulton successfully used a steam engine to propel a vessel through the water. Fulton's ship used the engine to power a small wooden paddle wheel as its propulsion system. The integration of steam engines into ships was the start of the Marine Engineering profession.
Before the integration of engines in ships, the maritime professions consisted of deck department jobs. This was because there was no engine for engineers to work on. The type of propulsion used before the engine powered paddlewheel was wind power.
Paddle wheel ships were the front runner of the industry for the next 30 years till the next type of propulsion came around. Only twelve years after Fulton’s Clermont had her first voyage, the Savannah marked the first sea voyage from America to Europe. Around 50 years later the steam powered paddle wheels had a peak with the creation of the Great Eastern, which was as big as one of the cargo ships of today, 700 feet in length, weighing 22,000 tons. The Great Eastern was said to be ahead of its time and was destined for failure. Since the 1800s there have been many improvements to the design of engines and propellers. The maritime industry
holds 90% of all international trade.〔Kane, J.R. (1971). Marine Engineering. New York: SNAME(page 2-3)〕
Marine Engineers work on more than just engines in ships. Marine engineers are also responsible for building and maintaining offshore oil rigs. These oil rigs were first made by Henry L. Williams in 1896.〔Bruce A. Wells, (2003) Offshore Petroleum History, American Oil and Gas Historical Society. Retrieved 4/10/14 http://aoghs.org/offshore-exploration/offshore-oil-history/〕
