Polar Security Cutter Program
The Polar Security Cutter Program is a program to recapitalize the United States Coast Guard's aging fleet of icebreakers, currently consisting of the heavy icebreaker USCGC ''Polar Star'' and the medium icebreaker USCGC ''Healy'', with three new multi-mission vessels referred to as Polar Security Cutters (PSC). These heavy polar icebreakers will allow the USCG to perform its statutory missions in the Arctic as well as support the United States Antarctic Program with Operation Deep Freeze. The PSC program is managed by the USCG and United States Navy through an integrated program office. On 23 April 2019, Halter Marine Inc was awarded the contract for the detail design and construction of the lead PSC. The contract option for the second PSC was exercised on 30 December 2021. The first vessel is expected to enter service in 2025 and will be named USCGC ''Polar Sentinel''. In the future, the PSCs will be followed by the acquisition of three medium icebreakers referred to as Arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar-class Icebreaker
Polar-class icebreakers , are heavy icebreakers operated by the United States Coast Guard (USCG). These cutters, specifically designed for icebreaking, have reinforced hulls, special icebreaking bows, and a system that allows rapid shifting of ballast to increase the effectiveness of their icebreaking. The vessels conduct Arctic and Antarctic research and are the primary icebreakers that clear the channel into McMurdo Station for supply ships. All are homeported in Seattle, Washington. In addition to the two Polar-class icebreakers, the USCG has a third polar-capable icebreaker, . Both ''Polar Star'' and ''Polar Sea'' are near the end of their effective lifetimes, and have spent years moored because they were in need of expensive and unbudgeted upgrades. In November 2013 four senators proposed an amendment to the 2014 Defense Appropriations Act authorizing the construction of four new Polar-class vessels, at a cost of $850 million each. The four senators sponsoring the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USCGC Polar Sea (WAGB-11)
USCGC ''Polar Sea'' (WAGB-11) is a United States Coast Guard heavy icebreaker. Commissioned on 23 February 1977, the ship was built by Lockheed Shipbuilding and Construction Company of Seattle along with her sister ship, ''Polar Star'' (WAGB-10). Her home port is Seattle, Washington. ''Polar Sea'' has been out of service due to failure of five of her six Alco main diesel engines. Machinery ''Polar Sea'' has a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the operation of the ship. Its three shafts are each turned by either one gas turbine or two diesel-electric power plants. Each shaft is connected to a 16-foot (4.9-m) diameter, four-bladed, controllable-pitch propeller. For all three shafts, the diesel-electric plants can produce a total of 18,000 shaft horsepower (13,425 kilowatts) and the gas turbine plants ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

HVAC
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 Sick building syndrome, healthy building conditions are regulated with respect to temperature and ...

Halter Marine, Inc
A halter or headcollar is headgear that is used to lead or tie up livestock and, occasionally, other animals; it fits behind the ears (behind the poll), and around the muzzle. To handle the animal, usually a lead rope is attached. On smaller animals, such as dogs, a leash is attached to the halter. History Halters may be as old as the early domestication of animals, and their history is not as well studied as that of the bridle or hackamore. The word "halter" derives from the Germanic words meaning "that by which anything is held." Uses A halter is used to lead and tie up an animal.Loch, Wayne. "Haltering and Tying Horses."
