Located in the Bay of Muggia in the Gulf of Trieste (lat. 45° 36’ 45’’ N; long. 13° 46’ 36’’ E), the marine terminal is used for the unloading of crude oil which is then pumped into the transfer lines that connect the port facility with the tank farm of San Dorligo della Valle.
Pier number 1 has a length of 476 meters and is used for oil tankers with a maximum displacement of 144,000 metric tons.
Pier number 2 has a length of 490 meters and can receive tankers with a maximum displacement of 280,000 metric tons.
Each of the four berths is directly connected to the tank farm (which is located at a distance of about 5 km) via four pipes that transfer the unloaded oil using the tankers’ own pumps.
The piers are oriented east-northeast (in the direction of the Bora wind) and the axial distance between them is 250 metres.
Everything is monitored 24 hours a day and 7 days a week from a technologically advanced control room where highly specialised operators oversee all operations from the entry of the tanker into the harbour and the unloading and transferring of the crude oil to the ship’s departure.
Safety and environmental protection have always been a top priority for the company. It continuously invests in research and in the best technologies available on the market and implements projects aimed at improving the antipollution system and further increasing marine protection. In addition to fire detection equipment, particular attention is paid to antipollution measures.
The flagship project is OSR (Oil Spill Response), a new anti-pollution plan designed to respond to an oil spillage in the port by immediately recovering the oil.
This containment system envisages the surrounding and isolation of the affected area of sea in two stages. The first stage is a rapidly deployable bubble barrier capable of surrounding a vessel of 280 metres in about three minutes and the second stage, more substantial and flexible, takes the form of 2,100 metres of inflatable floating booms located inside containers positioned on four platforms.
This two-stage system is complemented by a permanent anti-pollution barrier located below the piers.
The safety system is completed by the weather radar, which is capable of identifying potential atmospheric turbulences within a radius of 30 miles, the thunderstorm detector, which monitors electrical activity in the atmosphere within the same radius in order to warn of the presence of storm cells and the vessel traffic system, which controls the entire harbour area by monitoring the route, speed and distance of all vessels.
In addition to the above, the Optimoor simulator assesses the quality and quantity of the moorings of each vessel prior to their berth and, finally, the tide gauge is used to indicate the correct sea level in order to optimise the safety of the mooring of tankers entering the terminal.
By unloading an average of 420 vessels and handling an average of 35 million tons of crude oil every year, most of which comes from North Africa, the Middle East, Nigeria and Russia, etc., the Siot Marine Terminal accounts for 75% of traffic in the Port of Trieste, as a result of which it is Italy’s busiest oil terminal.
