HMNZS Hawea (2007)
HMNZS ''Hawea'' is a Lake-class inshore patrol vessel of the Royal New Zealand Navy. ''Hawea'' was constructed between 2004 and 2007, and commissioned on 1 May 2009. She performs border and fisheries protection patrols. ''Hawea'' is the third ship of this name to serve in the Royal New Zealand Navy and is named after Lake Hāwea Lake Hāwea is New Zealand's ninth largest lake. The lake is in the Otago Region at an altitude of 348 metres. It covers 141 km² and reaches 392 metres deep. Lake Hāwea is named after a Māori tribe who preceded the Waitaha people in .... Both of the Lake-class were sold to the Irish Naval Service in 2023 being delivered in May 2023. They are due in service sometime in 2024 after commission works are completed. Both are planned to be based on the east coast of Ireland where sea conditions suit their capabilities.

Paxman VP185
The Paxman VP185 is an engine manufactured by Paxman, Colchester. It is used in marine and railway applications and available as both a V12 and V18. History The VP185 was launched in May 1993 as a successor to the Paxman Valenta. It differed from the Valenta with a 90-degree cylinder bank angle, rather than a 60-degree vee to reduce its height, unit pump injectors eliminating two camshafts, side by side connecting rods to reduce manufacturing costs, higher firing pressures; increased power output, improved fuel consumption and emissions performance. Beginning in 1994, a small number of British Rail Class 43 power cars were fitted with Paxman VP185 engines, however the majority retained Valentas into the 21st century. With the Class 43s in need of new engines in the mid-2000s, most operators opted for the MTU engines. East Midlands Trains, who already was the largest operator with 14, opted to standardise on VP185s, ultimately having 26 examples. The last was withdrawn from reg ...

Royal New Zealand Navy
The Royal New Zealand Navy (RNZN; mi, Te Taua Moana o Aotearoa, , Sea Warriors of New Zealand) is the maritime arm of the New Zealand Defence Force. The fleet currently consists of nine ships. The Navy had its origins in the Naval Defence Act 1913, and the subsequent purchase of the cruiser , which by 1921 had been moored in Auckland as a training ship. A slow buildup occurred during the Interwar period, and then perhaps the infant Navy's finest hour occurred soon after the beginning of World War II when fought alongside two other Royal Navy cruisers at the Battle of the River Plate in December 1939. History Pre–World War I The first recorded maritime combat activity in New Zealand occurred when Māori in war waka attacked Dutch explorer Abel Tasman off the northern tip of the South Island in December 1642. The New Zealand Navy did not exist as a separate military force until 1941. The association of the Royal Navy with New Zealand began with the arrival of Lieutenant ...

Small Arms
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber (i.e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controllable Pitch Propeller
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MAN Diesel
MAN Diesel SE was a German manufacturer of large-bore diesel engines for marine propulsion systems and power plant applications. In 2010 it was merged with MAN Turbo to form MAN Diesel & Turbo. History * In 1980, MAN acquired the Burmeister & Wain Danish shipyard and diesel engine producer. Though engine production at Christianshavn was later discontinued in 1987, successful engine programs were rolled out. At Teglholmen in 1988 a spare parts and key components production factory was established as was an R&D Centre at the same site in 1992. Though all Copenhagen operations were consolidated at Teglholmen in 1994 and the last volume production unit at the B&W Shipyard was delivered in 1996, in 2000 MAN B&W Diesel two-stroke diesel engines had over 70% market share, with a substantial number of MC-line engines on order. * The electronically controlled line of ME diesel two-stroke engines was added in 2002 with a maximum cylinder bore of 108 cm.

Otago Harbour
Otago Harbour is the natural harbour of Dunedin, New Zealand, consisting of a long, much-indented stretch of generally navigable water separating the Otago Peninsula from the mainland. They join at its southwest end, from the harbour mouth. It is home to Dunedin's two port facilities, Port Chalmers (half way along the harbour) and at Dunedin's wharf (at the harbour's end). The harbour has been of significant economic importance for approximately 700 years, as a sheltered harbour and fishery, then deep water port. Geography The harbour was formed from the drowned remnants of the giant Dunedin Volcano, centred close to what is now Port Chalmers. The remains of this violent origin can be seen in the basalt of the surrounding hills. The last eruptive phase ended some ten million years ago, leaving the prominent peak of Mount Cargill. The ancient and modern channel runs along the western side of the harbour, the eastern side being shallow, with large sandbanks exposed at low tide. T ...

Lake-class Inshore Patrol Vessel
The Lake-class inshore patrol vessel (also known as the ''Rotoiti'' class and the Protector class) is a ship class of inshore patrol vessels (IPVs) of the Royal New Zealand Navy (RNZN) and the Irish Naval Service which replaced the RNZN's s in 2007–2008. All four vessels are named after New Zealand lakes. Following long-running Navy retention problems in the wake of NZDF "civilianisation", two of the four vessels were tied up, inactive, in a 'Reduced Activity Period' for long periods between 2013 and 2018. In June 2019 the New Zealand Government announced that two of the patrol vessels would be withdrawn from service, and they were decommissioned in October that year. Design and construction Conceived as part of Project Protector, the Ministry of Defence acquisition project to acquire one multi-role vessel, two offshore and four inshore patrol vessels. The Project Protector vessels were to be operated by the RNZN to conduct tasks for and with the New Zealand Customs Service, t ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first trans-Atlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On Apr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
