LNG? Methanol as fuel? Hybrid systems? Tier 4? Reducing noise? Cutting emissions without crushing fuel economy? Marine News readers have questions and Bob Kunkel has answers. Kunkel, President of Alternative Marine Technologies, previously served as the Federal Chairman of the Short Sea Shipping Cooperative Program under the Maritime Administration and Department of Transportation from 2003 until 2008. A past Vice President of the Connecticut Maritime Association, he is a contributing writer for Maritime Professional and Marine News. A graduate of the Massachusetts Maritime Academy, Kunkel sailed as a licensed engineer and eventually continued his career in ship construction at NASSCO, San Diego, Hyundai Heavy Industries, S. Korea, Chengxi Shipyard and Dalian New Shipyard in China. He is a senior member of the Special Committee on Ship Operation with ABS and an elected member of the National Cargo Bureau. This month, as our featured INSIGHTS executive, he weighs in on propulsion technology, as perhaps no one else in industry can.
Marine has been a leader, supplying over 900 diesel electric packages since delivering its first genset 2003. Early adopters of this flexible propulsion technology included the Rigdon Marine with twenty vessels and France-based Bourbon Offshore with more than 100 vessels. In late 2011 Aries Marine built

Major innovations in both engines and propulsion technology are taking place in this dynamic sector between ‘boats’ and ‘ships’. In the shadow of global recession it is clear that industry has realized

Mike Poole were on hand at OI to explain its potential. “AutoNaut is revolutionary,” said Poole, “because it is the first commercial use of a wave propulsion technology that can be scaled from a 1 meter hull to a ship. Such zero emission power, using the energy of the waves to propel a vessel, has great future
