| 摘要： | Anytime there's a legit, suitably notable "first-in-the-world" introduction, it's usually a big deal. Such it was on a rainy day in 2009 when Foss Maritime unveiled the world's first hybrid tug, the Carolyn Dorothy. About 300 guests heard speakers from Foss and the ports of Los Angeles and Long Beach tout the new environmental cred of the tug, which was the point of the ports' $1.3 million grant money that helped build it. The tug's hybrid concept was developed after Foss analyzed its harbor tugs' duty cycles in LA/LB and realized that maximum power was only needed a small part of the time, but the 78′×34′ tug would still need to have about 60 tons of bollard pull. |
