With a maximum speed of 19.9 knots (36.9 km/h; 22.9 mph) [4] the Nordic is able to reach any stricken vessel in German North Sea waters within two hours. In order to be able to operate in a contaminated atmosphere, the ship has been fitted with superstructures that can be sealed tight and are explosion-proof.
Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft.It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient ...
[4] A tugboat is typically rated by its engine's power output and its overall bollard pull. The largest commercial harbour tugboats in the 2000s–2010s, used for towing container ships or similar, had around 60 to 65 short tons-force (530–580 kN) of bollard pull, which is described as 15 short tons-force (130 kN) above "normal" tugboats.

The Lloyd's Open Form, formally "Lloyd's Standard Form of Salvage Agreement", and commonly referred to as the LOF, is a standard form contract for a proposed marine salvage operation. Originating in the late 19th century, the form is published by Lloyd's of London and is the most commonly used form for international salvage.

Tugs are attached to the vessel by a towline, and develop pulling forces with their engines and propellers. Salvage ground tackle is a system of anchors, ground legs, [notes 3] and hauling gear [notes 4] rigged to pullers, purchases, [notes 5] or winches, on a platform, which may be the stranded ship, a salvage ship, a barge, or the shore.
Serco Marine Services supports the Naval Service and the Royal Fleet Auxiliary (RFA) in both port and deep water operations. [7] In port and UK waters, Marine Services is primarily tasked with berthing and towage activities located at the three main naval bases; Devonport, Portsmouth and Clyde.
The German concept of emergency towing prescribes a maximum response time of two hours for any incident in German coastal waters. [10] This requires three ETVs in the North Sea and five in the Baltic Sea despite a considerably smaller area to cover there. Equipment and performance of the vessels have been adapted to the size of the vessels in ...
