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.

Transit passage is a concept of the law of the sea, which allows a vessel or aircraft the freedom of navigation or overflight solely for the purpose of continuous and expeditious transit of a strait between one part of the high seas or exclusive economic zone and another.

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.
[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.

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.
Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air or ground, [1] but significantly slower for longer distances.
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 ...
