There is also a petrochemical plant from which benzene and other petro chemicals are loaded.
The Puerto Ingeniero Rocca Quay is the site of a cold-rolling steel mill where imports of raw materials (in coils) are transformed into cold-rolled steel sheets and wire for export.

3. Vessels with a LOA exceeding 84m require 2 tugs entering and sailing.
4. Twin screw vessels with an LOA up to 105m or vessels of up to 11 5rn LOA fitted with bow thruster, require 1 tug.
The above includes the 5% tolerance permitted by the Coast Guard.
Mooring information: Special regulations for Gran Dock require vessels to moor, whenever possible, with the bow outwards facing the access channel, so as to be able to get away quickly in the event of the outbreak of fire.
Vessels that cannot so moor, will be assigned to Berths No 4, 5, 10 and 11 nearest to Cuatro Bocas. All tankers must sail immediately on finishing, loading or discharging petroleum products.
When vessels over 175m in length or with a draft of more than 6.70m have to move stern first in Gran Dock, the Prefecture will previously shift any draft moored on either side of the Frigorifico Armor zone, of over 5m beam.
The turning basin can be used only by vessels less than 175m in length. Turbine steamers over 140m in length entering or leaving Gran Dock, must not turn in Cuatro Bocas or in the turning basin at night time.
