The jetty head is the largest structure of its kind in Britain and stands over a mile from the shore in about 36 meters (118 feet) of water. It is 443 meters (1,453 feet) long. The outer berth can accommodate ships of upto 350,000 tonnes dead weight and the inner berth has a 70,000 tonnes dead weight limitation but with limited dredging of the approach this could when required be increased to 150,000 tonnes dead weight.
Iron Ore was taken from the holds of ships by the two ship uploaders each with a capacity of 3,000 tonnes per hour. These uploaders with a height of 72 meters (236 feet) and each weighing 2,500 tonnes are among the largest in the world.
Ore and coal are moved between ship and shore along an enclosed system of conveyor belts rated at 6,000 tonnes per hour for ore. Between the jetty and the stockyard is a sampling station where the ore is tested in accordance to the International Standards Organization who checks on ferrous content, moisture and size.
Since British Steel Ravenscraig closed down in 1992 only coal has been unloaded at Hunterston
