Jensen Maritime Selected by Bollinger Shipyards for Final Design Work on New High-Bollard-Pull Ocean-Going Tugs

(Seattle, Wash.; June 22, 2010) – Jensen Maritime Consultants Inc. has been selected by Bollinger Shipyards, Inc., to complete the final design drawings and specifications for two new 10,880-horsepower, high-bollard-pull, ocean-going tugboats.

The tugs are the beginning of a new-build program at Crowley Maritime Corporation to further enhance its ocean towing, salvage and offshore support capabilities. The Ocean Wave and Ocean Wind will have a minimum bollard pull of 150 metric tons and a range of approximately 12,600 nautical miles at 15 knots free running. The tugs will measure 144 feet long, 46 feet wide and have a draft of 20 feet. They will have twin screw, controllable pitch propellers (CPP), in nozzles, and will be equipped with high lift rudders.
Once delivered, the long-range, high capacity, ocean-towing vessels will help further Crowley’s position as an industry leader in offshore towing for years to come.
Jensen’s design efforts, led by Project Manager Eric Blumhagen, include vessel arrangements, hull and deckhouse lines, structural design, equipment foundations design and stability. Bollinger will be handling systems design and the production lofting effort.
“We [Jensen] work with the shipyard and owner to ensure that the owner gets the boat that they want and the builder gets it done in a cost-effective way,” said Blumhagen.

Bollinger, who won the new-build contract in February, is scheduled to deliver the first of the Ocean class tugs in 2011. The tugs will be constructed at Bollinger Marine Fabricators in Amelia, La.
“Bollinger is really excited to have the opportunity to build these tugs for Crowley, and we look forward to working with Jensen to facilitate in the design,” said Chris Bollinger, executive vice president of new construction.
