TORP LNG together with its partner Sorgenia, is developing an offshore LNG receiving terminal off the coast of Italy, Azzurro LNG Offshore Energy Terminal. The Sorgenia Group is made up of different companies operating in distinct areas and specific stages of the energy business. It is the first private operator in the Italian energy market, with 10,000 GWh sold to 400.000 customers in 2008. Sorgenia had a generation capacity of 2.8 GWh in 2008, and is one of the largest natural gas buyers in Italy. The project consists of two major elements; an offshore part including the two HiLoads, and an onshore facility with blending, odorizing and measuring facilities. The offshore facility consists of two HiLoad terminals which will transfer LNG to the onshore facility. Normally one HiLoad is in operation at a time, while the other is in stand-by mode. The HiLoad design is such that the systems on the stand-by HiLoad can be kept in cold condition for a period of at least seven days between each off-loading. Each HiLoad terminal comprises of the following regasification equipment:
The location of the terminal will be about 20 km from shore in approximately 80 m water depth. The distance between each HiLoad will be about 2 nautical miles. The HiLoad will dock onto the LNG tankers for offloading and regasification of LNG cargo and feeding regasified natural gas into the pipeline system. The control station is on-shore. The peak send-out capacity from each HiLoad is 1.65 million Sm³/h with a max. pressure of 100 bar, and a temperature of min. 0º C LNG from the ships is transferred to the HiLoad through normal LNG transfer arms, then boosted to the required send-out pressure, vaporized and sent through flexible risers to a subsea swivel and pipeline connecting HiLoad with the Shore Facilities. At the Shore Facilities the gas will have its Wobbe Index and calorific value adjusted by injection of nitrogen, odorized, and metered before being sent onto the export gas pipeline.
