In the summer of 2011, the tanker STI Heritage left Houston, Texas and made the long, arduous journey to Thailand, eventually arriving with over 60,000 tons of condensed gas.1 What made this trip special was not the start and end points (these are two major ports), but rather how, and how fast, the tanker made the journey. Instead of the traditional route via the Suez Canal, the STI Heritage

The use of this lane is, in and of itself, not unique, as historically portions of it have been navigable for two summer months each year. What made the STI Heritage voyage special, however, was the speed with which the vessel completed the entire route: eight days.2 This was a record for the Northeast Passage (broken weeks later by a gas tanker that made the trip in just over six days), which has seen a dramatic reduction of summer ice over the past decade, making commercial use of the lane economically viable, at least if one extrapolates from the numbers. In 2009, only two commercial vessels made the voyage. In 2011, that number had increased to 18.3
