Fitting-out
Fitting out, or outfitting, is the process in shipbuilding that follows the float-out/launching of a vessel and precedes sea trials. It is the period when all the remaining construction of the ship is completed and readied for delivery to her owners. Since most of the fitting-out process is interior work, this stage can overlap with latter stages, such as the sea trials. Launching or floating After a vessel has been floated (in contemporary shipbuilding) or launched (in traditional shipbuilding), it is then towed out of its drydock and moored at a fitting-out berth. While still afloat, its construction is then continued. Depending on the type of vessel, fitting-out can last weeks or many months. Vessels with comparatively little space for human occupation, such as oil tankers, bulk carriers and container ships, can take the least time for fitting. Conversely, passenger ships take the longest. The process can include: * completion of the superstructure, * installation of the ship ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poltava Battleship Fitting-out, 1912
Poltava (, ; uk, Полтава ) is a city located on the Vorskla River in central Ukraine. It is the capital city of the Poltava Oblast (Oblast, province) and of the surrounding Poltava Raion (raion, district) of the oblast. Poltava is administratively incorporated as a City of regional significance (Ukraine), city of oblast significance and does not belong to the raion. It has a population of History It is still unknown when Poltava was founded, although the town was not attested before 1174. However, for reasons unknown, municipal authorities chose to celebrate the city's 1100th anniversary in 1999. The settlement is indeed an old one, as archeologists unearthed a Paleolithic dwelling as well as Scythian remains within the city limits. Middle Ages The present name of the city is traditionally connected to the settlement Ltava which is mentioned in the Hypatian Chronicle in 1174.

Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC. Egyptian potte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drydock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passenger Ship
A passenger ship is a merchant ship whose primary function is to carry passengers on the sea. The category does not include cargo vessels which have accommodations for limited numbers of passengers, such as the ubiquitous twelve-passenger freighters once common on the seas in which the transport of passengers is secondary to the carriage of freight. The type does however include many classes of ships designed to transport substantial numbers of passengers as well as freight. Indeed, until recently virtually all ocean liners were able to transport mail, package freight and express, and other cargo in addition to passenger luggage, and were equipped with cargo holds and derricks, kingposts, or other cargo-handling gear for that purpose. Only in more recent ocean liners and in virtually all cruise ships has this cargo capacity been eliminated. While typically passenger ships are part of the merchant marine, passenger ships have also been used as troopships and often are commissio ...

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Heating, Ventilation, And Air Conditioning
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Furniture
Furniture refers to movable objects intended to support various human activities such as seating (e.g., stools, chairs, and sofas), eating (tables), storing items, eating and/or working with an item, and sleeping (e.g., beds and hammocks). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards, shelves, and drawers). Furniture can be a product of design and can be considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. It can be made from a vast multitude of materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflects the local culture. People have been using natural objects, such as tree stumps, rocks and moss, as furniture since the beginning of human civilization and continues today in some households/campsites. Ar ...

Queen Mary 2
RMS ''Queen Mary 2'' (also referred to as the ''QM2'') is a British transatlantic ocean liner. She has served as the flagship of Cunard Line since succeeding '' Queen Elizabeth 2'' in 2004. As of 2022, ''Queen Mary 2'' is the only ocean liner (as opposed to a cruise ship) still in service. The ship was officially named ''Queen Mary 2'' by Queen Elizabeth II in 2004 after the first of 1936. ''Queen Mary'' had in turn been named after Mary of Teck, consort of King George V. With the retirement of ''Queen Elizabeth 2'' in 2008, ''Queen Mary 2'' is the only transatlantic ocean liner in regular service between Southampton, England, and New York City, United States. The ship is also used for cruising, including an annual world cruise. She was designed by a team of British naval architects led by Stephen Payne, and was constructed in France by Chantiers de l'Atlantique.
