"Natural gas is one of the world's most-sought-after fuels; not only is it cleaner burning and more efficient than traditional fossil fuels, it's also more efficient to transport," says Keith Fitz-Gerald.

In his always-intriguing The Money Map Reporter, he explains, "Our latest featured idea is Bermuda-based Teekay LNG Partners LP (NYSE: TGP), a liquid natural gas shipper which we consider a safe port in any economic storm."

"Many investors don't realize that liquid natural gas (LNG) comes from Indonesia, Malaysia, Qatar and other faraway places – transported by specially designed ships – and that we don't have the industrial capacity to meet modern-day demand.

"Teekay LNG Partners LP is a publicly traded master limited partnership formed by Teekay Corp. (NYSE: TK), a provider of international transportation services for petroleum products.

"The company provides marine transportation services for LNG through a fleet of ships that it owns or operates under various long-term contracts known as 'time charters.' These 15 to 20-year pacts are reached with such major energy companies.

"Shipping stocks can be a good port in a financial storm," says Ivan Martchev in Leeb's Income Performance Letter. Here, the advisor looks at Teekay LNG Partners (NYSE: TGP).

"Some shippers take their chances in the spot market; these should be avoided. Teekay, however, offers a high yield and lower earnings volatility due to its lower-than-average exposure to the spot market.

"Teekay is well exposed to the growing market for liquidified natural gas (LNG). The growth profile of the LNG market is compelling. The vast majority of the world's natural gas reserves are stranded in Eurasia and the Middle East, while consumption is greatest in the U.S., Far East and Europe.

"Imports of LNG to the U.S., for example, are expected to increase by more than 400%, by some estimates, between now and 2012. Clearly, there is wide-eyed potential growth in the LNG market.

"There are also high barriers to entry in its transportation since it requires huge investments in loading and reliquification terminals for highly specialized ships. Given the support of its parent company -- Teekay Corp. -- Teekay LNG Partners is a force far larger than its relatively small size would have your believe at first blush.

"The company's growth is virtually assured for years to come due to the imbalance in the geographic distribution of reserves and consumers of natural gas. Teekay LNG Partners, yielding 7.7%, is a publicly-traded master limited partnership, which means you should look into the peculiarities of tax treatment of distributions."
