Case Studies and Applied Products
HRC 100 & 200 Series T-headed reinforcement
T-headed rebar is common reinforcing steel with a small steel plate attached to one or both ends of the bar. The T-head works as anchoring device as an alternative to hooks or bends. The generic term for T-heads is "mechanical anchoring ... [more]
HRC 400 series reinforcement couplers
High performance reinforcement couplers with proven and documented quality. Exceed all known requirements for reinforcement couplers.
[more]Excerpt from Wikipedia
The Adriatic LNG terminal is a liquid natural gas offshore terminal, formally known as Terminale GNL Adriatico Srl. Located in the northern Adriatic 9 miles (14 km) offshore of Porto Levante, Porto Viro, near Rovigo, Italy, it is the world's first offshore gravity-based structure LNG regasification terminal. The terminal is operated by ExxonMobil (70%), Qatar Terminal Ltd., a subsidiary of Qatar Petroleum (23%), and Snam (7%).
Construction
The terminal facility was built in Campamento, parish of San Roque, Spain, then towed to Porto Levante, Italy. Construction started in October 2003 and finished in August 2008. The LNG tanks were constructed in South Korea. The pipeline that connects to the terminal is located south of the Levante Po River mouth near Scanno Cavallari.
Moving
After construction was completed in Campamento, the rig was towed by four tugboats to its current location off the coast of Rovigo. The flotilla traveled the 1,700 nautical miles (3,100 km; 2,000 mi) in 16 days to reach the site. It traveled at an average speed of 4.4 knots (8.1 km/h; 5.1 mph). When it arrived, the terminal was weighted down by water to ensure it was permanently positioned on the seabed.
Operations
Operations started in the mid of 2009. It received its first cargo on 11 August 2009. When fully operational, it stores and regasifies 8 billion cubic metres (280 billion cubic feet) of natural gas per year, enough to meet 10% of Italy's natural gas needs. The terminal receives a LNG carrier every three days from Qatar. The gas is then regasified and sent to the Italian gas network by a pipeline from the terminal to the coast.
