Jensen Completes Environmentally Friendly Tugboat Design for Harley Marine
Vessel One of the First to be Equipped with Environmentally Friendly Tier III Engines
Jensen Maritime Consultants, Inc., recently completed the custom design work for the Bob Franco, a new Azimuth Stern Drive (ASD) tugboat for Harley Marine Services. The vessel - measuring 120 feet in length and 35 feet in width - is one of the first to be powered by Tier III CAT C175 engines, which have lower emissions than Tier II models, making it a more environmentally friendly option. Construction on the vessel is underway at Diversified Marine, Inc., in Portland, Ore., and is expected to be completed in 2012.
"The construction of a tugboat that meets Tier III emissions compliance is a great step forward in environmental protection for our industry," said Jensen's Johan Sperling, vice president. "It was important for us to design a powerful and capable tugboat for Harley, but also one that takes care of the environment in the process."
Bob Franco, which will be home ported in Seattle, will have a crew capacity of 13. The vessel is the fourth in a series of these tugboats designed by Jensen. The first three were designed and built for Western Towboat in Seattle.
Once construction is complete on the Bob Franco, it will be used to assist barges delivering supplies to rural communities in Alaska. As such, the tugboat was designed with highly capable Z-Drives, which offer increased maneuverability when working with vessels in the many narrow channels and fast tides of Alaska. Additionally, the tug is designed to more easily move alongside barges to help them dock safely in nearly any condition.
"Being selected to design this tugboat was an honor," said Sperling. "We look forward to seeing it in action and know that Harley Marine Services will be very pleased with the design, quality and performance."
Harley Marine Services has been recognized for its environmental initiative, commitment and stewardship. Since 2009, they have been awarded four major environmental awards: the 2011 Marine Environmental Business of the Year for Environmental Initiative from the Port of Seattle and Propeller Club of Seattle; first place for Environmental Initiative in the 2010 WorkBoat Environmental Awards; the 2010 EPA Environmental Quality Award (the first Marine Environmental Award from the EPA); and third place for Environmental Management System in the 2009 WorkBoat Environmental Awards.
Some of the environmental initiatives have included an aggressive overhaul and replacement program to upgrade tugboat engines to reduce NOx emissions, a new generation of patented barge mounted Vapor Recovery Units that exceeds all air quality requirements, and a very robust Environmental Management System which has been implemented in all segments of the company. Harley Marine Services has attained International Organization for Standardization (ISO) 14001 Environmental Certification for all subsidiary companies including tugs, barges, shops and offices, in addition to ISO 9001 Safety Management System and American Waterways Operators - Responsible Carrier Program.
