Baltic (tug)
The ''Baltic'' is a German emergency tow vessel (ETV) commissioned in 2010. The vessel which was built in Spain by Astilleros Armon is owned by Arbeitsgemeinschaft Küstenschutz of Germany, a consortium of tugboat companies. The Federal Ministry of Transport, Building and Urban Development of Germany has chartered the vessel to protect the German coastline. The ''Baltic'' replaced the tugboat ''Fairplay 26'' as an ETV and operates from Warnemünde in the western Baltic Sea. She was commissioned on 24 September 2010. The Baltic features a bollard pull of 127 tons and a maximum speed of . In October 2010, only a few days after commissioning, the ''Baltic'' was deployed to assist during the fire on the ferry '' Lisco Gloria'' off the island of Fehmarn. Technical dates Engine The ''Baltic'' is driven by two main engines of the General Electric 16V250MDB3 type which are connected to two Schottel controllable pitch propellers via transmissions and drive shafts. The engines are 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warnemünde
(, literally ''Mouth of the Warnow'') is a seaside resort and a district of the city of Rostock in Mecklenburg, Germany. It is located on the Baltic Sea and, as the name implies, at the estuary of the river Warnow. is one of the world's busiest cruise ports. History Founded in about 1200, was for centuries a small fishing village with minor importance for the economic and cultural development of the region. In 1323 lost its autonomous status as it was purchased by the city of Rostock in order to safeguard the city's access to the Baltic Sea. It was not until the 19th century that began to develop into an important seaside resort. Today has approximately 8,400 inhabitants. Economy Once completely dependent on the fishing industry, 's economic alignment has shifted inevitably from the primary to the secondary and tertiary sector. Besides the Nordic Yards Warnemünde ship yard (the former ), the economy largely depends on tourism. The construction of a modern cruise ...

Tugboats Of Germany
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightne ...

Nordic (tug)
The ''Nordic'' is a German emergency tow vessel (ETV) stationed on an offshore position north of the East Frisian island of Norderney. It is the most powerful tugboat in German waters, operated by Fairplay Towage Group. History Construction and commissioning The construction and commissioning of the ''Nordic'' were a consequence of the ''Pallas'' accident off Amrum island in 1998 when the cargo vessel ran aground and lost a substantial amount of oil. Especially the Schutzgemeinschaft Deutsche Nordsee association and many other non-governmental organisations for the protection of the environment had worked towards the commissioning of a new emergency tow vessel on the German North Sea coast. Constructions began on 27 October 2009 on the P+S Werften yards, formerly known as Peene-Werft, in Wolgast, Mecklenburg-Western Pomerania, with yard number 563. Sea trials were held in October 2010. In the course of these trials, the ''Nordic'' delivered a bollard pull of 207 tons (ca. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deluge Gun
A deluge gun, fire monitor, master stream or deck gun is an aimable controllable high-capacity water jet used for manual firefighting or automatic fire protection systems. Deluge guns are often designed to accommodate foam which has been injected in the upstream piping. Installation Deluge guns are often fitted to fire boats, tug boats, and atop large fire trucks for use in manual firefighting, where they can be aimed and operated by one firefighter and are used to deliver water or foam from outside the immediate area of the fire. Deluge guns are sometimes installed in fixed fire protection systems to protect high hazards, such as aviation hangars and helicopter landing pads. Similarly, facilities with highly flammable material such as oil refineries may have permanently-installed deluge guns. Most apparatus-mounted deluge guns can be directed by a single firefighter, compared to a standard fire hose which normally requires several. Deluge guns can be automatically positioned f ...

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a mechanical brake or ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the crew member turns the winch handle with one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt-ampere
A volt-ampere ( SI symbol: V⋅A or V A, simplified as VA) is the unit for the apparent power in an electrical circuit. The apparent power equals the product of root mean square voltage (in volts) and root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits. In direct current (DC) circuits, this product is equal to the real power, in watts. The volt-ampere is dimensionally equivalent to the watt: in SI units, 1 V⋅A = 1 W). VA rating is most used for generators and transformers (and other power handling equipment) where loads may be reactive (inductive or capacitive). Formulation For a simple electrical circuit running on direct current, the electrical current and voltage are constant. In that case, the real power (''P'', measured in watts) is the product of the electrical current (''I'', measured in amperes) and the voltage from one side of the circuit to the other (''V'', measured in volts): ...

Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kort Nozzle
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is a shrouded propeller assembly for marine propulsion. The cross-section of the shroud has the form of a foil, and the shroud can offer hydrodynamic advantages over bare propellers, under certain conditions. Advantages are increased efficiency at lower speeds (10 knots), course stability when sailing astern, and increase of cavitation. Ducted propellers are also used to replace rudders. History Luigi Stipa in 1931 and later Ludwig Kort (1934) demonstrated that an increase in propulsive efficiency could be achieved by surrounding the propeller with a foil-shaped shroud in the case of heavily loaded propellers. A "Kort Nozzle" is refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ...

Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft ( Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
