GasLog, which operates 14 ships to transport natural gas, registered with the SEC for a $350 million initial public offering on Tuesday. The Monaco-based company, which was founded in 2001, booked $65 million in sales for the twelve months ended June 30, 2011. Revenues were flat at around $8 million from 2007 to 2009 before growing to $40 million in 2010, when its two wholly owned ships were delivered. Goldman Sachs, Citi, J.P. Morgan and UBS have been chosen as lead underwriters. GasLog plans to list on the New York Stock Exchange under the symbol GLOG.
