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.

[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.

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.
A form of what is now called general average was included in the Lex Rhodia, the Rhodes Maritime Code of c. 800 BC. [4] Julius Paulus quoted from the law around the turn of the 3rd century, and these quotes are preserved, and an excerpt is included in Justinian's 6th-century Digest of Justinian (part of the Corpus Juris Civilis), although the Lex Rhodia is itself now lost.
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.
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 ...
