LNG tugs are coming, but when is unclear

摘要

Within the past two years, liquefied natural gas (LNG) has gained a major foothold in the U.S. maritime industry. Large ferry companies in the Unites States and Canada are planning to adopt the fuel, and several U.S. operators have placed orders for offshore supply vessels and containerships. One key exception to this trend has been the tugboat industry, where several gas- powered vessels are in the design pipeline but none are in use.
