LÉ Róisín (P51)
LÉ ''Róisín'' (P51) is the lead ship of her class of offshore patrol vessel in the Irish Naval Service. Commissioned in 1999, the ship's primary mission is fisheries protection, search and rescue, and maritime protection operations, including vessel boarding (attack), boardings. Róisín or Róisín Dubh, is often used as an allegory for Ireland. However, the original Róisín Dubh was a daughter of Hugh O'Neill, Earl of Tyrone, Red Hugh O’Neill, Earl of Tyrone in the late 16th century. Design The ship was designed by STX Canada Marine (now Vard Marine) and has an all-steel hull based on the Mauritius, Mauritian MCGS Vigilant, Vigilant patrol vessel launched in 1995, but without the helicopter deck and hangar facilities. The level of automation incorporated into the ship's systems allows the ship to be operated with just 47 crew including eight officers. The vessel is designed for winter North Atlantic operations.

Otobreda 76 Mm
The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales. The system is compact enough to be installed on relatively small warships. Its high rate of fire and the availability of several types of ammunition make it capable of short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying maneuvering anti-ship missiles. It can be installed in a stealth cupola. The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was favored over the French 100mm naval gun for the joint French/Italian project and FREMM frigate. The Super Rapid Gun Mount (SRGM) variant is being license-manufactured in India by Bharat Heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cork Harbour
Cork Harbour () is a natural harbour and river estuary at the mouth of the River Lee (Ireland), River Lee in County Cork, Ireland. It is one of several which lay claim to the title of "second largest natural harbour in the world by navigational area" (after Port Jackson, Sydney). Other contenders include Halifax Harbour in Canada, Trincomalee Harbour in Sri Lanka and Poole Harbour in England. The harbour has been a working port and a strategic defensive hub for centuries, and it has been one of Ireland's major employment hubs since the early 1900s. Traditional heavy industries have waned since the late 20th century, with the likes of the closure of Irish Steel in Haulbowline and shipbuilding at Verolme Cork Dockyard, Verolme. It still has strategic significance in energy generation, shipping, refining and pharmaceuticals development. Geography The main tributary to the harbour is the River Lee which, after flowing through Cork (city), Cork city, passes through the upper harbour ...

Haulbowline
Haulbowline (; ) is an island in Cork Harbour off the coast of Ireland. The world's first yacht club was founded on Haulbowline in 1720. The western side of the island is the main naval base and headquarters for the Irish Naval Service, with the eastern side previously used for heavy industry and later redeveloped as a park. Since 1966, the island has been connected to the mainland by a roadbridge. Etymology The island's name may derive from Old Norse ''ál-boling'' or similar = "eel dwelling" ("area where there are conger eels"). The 17th and 18th-century spellings end in "-ing"; there may have been nautical influence on the spelling later. The Irish language name for the island, ''Inis Sionnach'', translates to "island of the foxes". Demographics Naval history At a strategic and deepwater position in the harbour, the island has long been a military base. The island was first fortified in 1602, and initially an important base for the British Army. In 1603 the Cork city f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LÉ Róisín In Dublin
The Naval Service () is the maritime component of the Defence Forces of Ireland and is one of the three branches of the Irish Defence Forces. Its base is in Haulbowline, County Cork. Though preceded by earlier maritime defence organisations, the Naval Service was formed in 1946. Since the 1970s a major role of the Naval Service has been the provision of fisheries protection in Ireland's exclusive economic zone (EEZ). Other roles include sea patrol, surveillance, and smuggling prevention. Occasionally the service undertakes longer missions in support of other elements of the Defence Forces, Irish peacekeepers serving with the United Nations, or humanitarian and trade missions. The Naval Service has an active establishment of 1,094 and a reserve establishment of 200. Like other components of the Defence Forces, the Naval Service has struggled to maintain strength and as of late 2024 had only 719 active personnel, and 77 reserve personnel.

Rigid-hulled Inflatable Boat
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull (watercraft), hull bottom joined to side-forming air tubes that are inflated with air to high pressure to give the sides resilient rigidity along the boat's topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat. History Origins in Wales The concept of configuring a rigid hull surrounded by an inflated, compartmentalized buoyancy tube from prow to transom originated and evolved from the problems that plagued existing rubberized fabric bottom inflated motorboats: fabric wear-th ...

Differential GPS
Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS can increase accuracy of positional data by about a thousandfold, from approximately to . DGPSs consist of networks of fixed position, ground-based reference stations. Each reference station calculates the difference between its highly accurate known position and its less accurate satellite-derived position. The stations broadcast this data locally—typically using ground-based transmitters of shorter range. Non-fixed (mobile) receivers use it to correct their position by the same amount, thereby improving their accuracy. The United States Coast Guard (USCG) previously ran DGPS in the United States on longwave radio frequencies between and near major waterways and harbors. It was discontinued in March 2022. The USCG's DGPS was known as NDGPS (Nationwide DGPS) and was jointly administered by the Coast Guard and the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Maritime Distress Safety System
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention. It is a set of safety procedures, types of equipment, and communication protocols used for safety and rescue operations of the distressed ships, boats, and aircraft. It is supplemental to the International Convention on Maritime Search and Rescue (ICMSaR) adopted in 1979 and provides basis for the communication. GMDSS consists of several systems which are intended to perform the following functions: alerting (including position determination of the ship in distress) ships in the vicinity and ashore authorities, search and rescue coordination, locating (homing), maritime safety information broadcasts, general communications, and bridge-to-bridge communications. Specific radio carriage requirements depend upon the ship's area of operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
