The Baltic is a German emergency tow vessel (ETV) commissioned in 2010.

An emergency tow vessel, also called emergency towing vessel, (ETV) is a multi purpose boat used by state authorities to tow disabled vessels on high seas in order to prevent dangers to man and environment. The disabled vessel is either towed to a safe haven or kept in place against wind and current until commercial assistance by tug boats has arrived on site or until it has been repaired to the extent of being able to manoeuvre on its own. The need for ETVs as a preventive measure has arisen since the number of available commercial salvage tugs was reduced while potential dangers from individual vessels have increased. E.g. Spain has fourteen, Turkey has eleven, Germany operates eight, Norway has seven, France has five, Sweden three and the Netherlands, Poland, South Africa, Iceland and Finland each have one official emergency tug boat. Australia also operates emergency response vessels. The United Kingdom's four strong ETV fleet was to be disbanded in September 2011 due to budget cuts but the two vessels operating in Scottish waters received an extension of contract until the end of 2011.

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.^[3] She was commissioned on 24 September 2010.^[4]

Warnemünde 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. Warnemünde is one of the world's busiest cruise ports.

The Baltic Sea is a marginal sea of the Atlantic Ocean, enclosed by Denmark, Estonia, Finland, Latvia, Lithuania, Sweden, northeast Germany, Poland, Russia and the North and Central European Plain.

The Baltic features a bollard pull of 127 tons and a maximum speed of 17 knots (31 km/h; 20 mph).^[3]

Bollard pull is a conventional measure of the pulling power of a watercraft. It is defined as the force exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test under test conditions that include calm water, no tide, level trim, and sufficient depth and side clearance for a free propeller stream. Like the horsepower or mileage rating of a car, it is a convenient but idealized number that must be adjusted for operating conditions that differ from the test. The bollard pull of a vessel may be reported as two numbers, the static or maximum bollard pull - the highest force measured - and the steady or continuous bollard pull, the average of measurements over an interval of, for example, 10 minutes. An equivalent measurement on land is known as drawbar pull, or tractive force, which is used to measure the total horizontal force generated by a locomotive, a piece of heavy machinery such as a tractor, or a truck,, which is utilized to move a load.

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.

Fehmarn is an island in the Baltic Sea, off the eastern coast of Schleswig-Holstein, Germany, and c. 18 kilometers south of the Danish island of Lolland. It belongs to the district of Ostholstein, Germany.

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 16-cylinder Diesel units which can provide 4,239 kilowatts (5,685 hp) each at a nominal 1,050 revolutions per minute. The propellers are encased in Kort nozzles and have a maximum revolution speed of 170 rpm. Two thrusters are installed in the bow and the stern section respectively to improve the ship's manoeuvrability.

General Electric Company (GE) is an American multinational conglomerate incorporated in New York and headquartered in Boston. As of 2018, the company operates through the following segments: aviation, healthcare, power, renewable energy, digital industry, additive manufacturing, venture capital and finance, lighting, and oil and gas.

A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.

A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.

To provide electrical power, two generators with a power of 1,500 kVA each are coupled to the drive shafts. Additionally two main generators of 500 kVA and an emergency power unit (150 kVA) are installed on board.

Volt-ampere unit used for the apparent power in an electrical circuit

A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current. In direct current (DC) circuits, this product is equal to the real power in watts. Volt-amperes are useful only in the context of alternating current (AC) circuits.

Equipment

When commissioned, the Baltic was the most powerful tugboat along the German Baltic Sea coast. For towing tasks, the ship is equipped with two hydraulic winches. The towline has a diameter of 62 mm and a length of 500 m. Two fire monitors are installed on board.^[3]

A tugboat is a type of vessel that maneuvers other vessels by pushing or pulling them either by direct contact or by means of a tow line. Tugs typically move vessels that either are restricted in their ability to maneuver on their own, such as ships in a crowded harbor or a narrow canal, or those that cannot move by themselves, such as barges, disabled ships, log rafts, or oil platforms. Tugboats are powerful for their size and strongly built, and some are ocean-going. Some tugboats serve as icebreakers or salvage boats. Early tugboats had steam engines, but today most have diesel engines. Many tugboats have firefighting monitors, allowing them to assist in firefighting, especially in harbors.

Icebreaker Special-purpose ship or boat capable of maneuvering through ice-covered water

An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.

A ship model basin is a physical basin or tank used to carry out hydrodynamic tests with ship models, for the purpose of designing a new ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization that owns and operates such a facility.

LÉ Róisín (P51) is the lead ship of her class of offshore patrol vessel in the Irish Naval Service.
