North Mole, Gibraltar Harbour

[5][6] The L-shaped breakwater includes a Western Arm which runs south toward the Detached Mole,[4][7] and measures 500 metres (1,600 ft) in length.

The northern section of the harbour features the commercial port, which has a total length of almost 2,300 metres (7,500 ft) of quay on the North Mole (including its Western Arm) for cruise ships, cargo handling, and bunkering.

[12] The extensive changes to Gibraltar Harbour were largely financed through Britain's Naval Works Loan Act of 1895 and following years.

The plan that met with final approval of the Admiralty included construction of a dockyard and a modern defensive harbour, safe from torpedo attack.

[4] On the afternoon of 31 May 2011, the North Mole at Gibraltar Harbour was the site of an explosion involving an oil storage tank.

[14] Following the fire, concern was expressed about the availability of adequate supplies of fire-fighting foam prior to the blaze at the North Mole.

[15][16] On 8 June 2012, a bunkering accident off the North Mole resulted in an oil spill, with the release of three tons of fuel into the sea.
