Oil Terminal

There is a jetty and the ships come in for fuel. It goes out through hoses.There is a big pole where you mark where rocks are. There is a big escape wall if there is a fire and the water spray will also come on.

The Fire Pumps
It pumps in water all around the terminal at high pressure.The grey motor is 200 horse-power and it is electric.There is 200 horse-power diesel.

The Single Point Mooring
They tie the ships onto the buoy, they lie head to wind on one rope.

They can import or export crude-oil diesel and gas.There were plaques to commemorate the opening on 6th April 1967 and it was recommissioned in 1998, which was opened by Minister for Public Enterprise Mary O'Rourke on 15th April 1998

The Control TowerOil is stored in bulk and it is brought in by pipeline from a single-point mooring.
When it is time to export it is pumped out to ships.
There is an upper tank farm.
They use barrels as measurement (42 gallons).
The big tanks will hold 600,000 U.S. barrels.
They have a lower tank farm and two of them will hold 500,000 U.S. barrels.
When the tank is full the ladder will go horizontal.
Each tank has a valve known as a shell-valve which allows the flow to be controlled.
The 12 valves go into the manifold where it is condensed into several pipes.
A manifold is a series of pipes .
The oil leaves and heads out to the s.p.m.
They have a series of computers which show all the information on the terminal.
At the click of a mouse you can see all the information on all the tanks .
There are 36 valves which are 36 inches in diameter.
The s.p.m. has just two lines going out to it. These are connected to the PLEM(PipeLine End Manifold). Here the two actuator valves control the flow to and from the tank farm(Tanker) via the sub sea hoses.
There is a manifold on the sea-bed; the oil comes up through the top of the s.p.m. and the top of it swivels .
They have a pair of computers that control all the physical equipment on the ground. A millimetre of oil inside one of the tanks would be about 5 tonnes of liquid.
Computers examine the contents of the tanks.
