Lithuania Puts Plans to Import LNG From US On Hold

Lithuania has put plans to buy liquefied natural gas from the United States on hold because the LNG is not yet suitable for the Baltic state's gas system, its state energy company said on Wednesday. Lithuania's system was built to use Russian gas and state energy group Lietuvos Energija said U.S. LNG was much more calorific than Russian gas. The country opened an LNG import terminal in the Baltic Sea at the end of 2014, which allowed it to start importing from Norway and end its total dependence on gas imports from its former Soviet master, Russia. "We are not buying gas from the U.S. at the moment, because the gas they are offering at the moment does not meet specifications needed for our gas distribution system," Ernesta Dapkiene, a spokeswoman for Lietuvos Energija, told Reuters.

A Bundle of Advanced Technology

The close cooperation of the Finnish Maritime industry is evidenced in the highly capable icebreaking ships that it produces. Icebreakers are essential to Finland’s existence, as the specialized ships enable the country to keep its shipping lanes operational during the harshest winter months. However, traditional icebreaker design made for poor navigating vessels in open water, and thus were rendered useful during only the winter months. This was acceptable, but very expensive, as icebreakers by nature represent a significant maintenance challenge and cost. The solution: creating a new design icebreaker that could be used, profitably, year-round.

Aluminum Gone "Bad"

There has been a lot of discussion in the marine industry over the past year with regard to "bad" aluminum. To briefly recap, a number of boat builders purchased aluminum from a supplier that met the requirements of ASTM 5083 H321. This alloy is accepted by both Lloyds Register (Lloyds) and Det Norske Veritas (DNV) for building aluminum vessels. After the aluminum was used to construct some vessels, the operators began to observe surface pitting corrosion. Upon investigation, it was discovered that the purchased plate had been treated differently during manufacturing, with the result that manganese nodules were precipitating out of the alloy, thus making it susceptible to inter-granular corrosion. The result was that newly-built vessels had to be rebuilt and their original hulls scrapped.
