It’s been a challenge to ? nd a diesel generator—by far the largest tugs with the largest experienced people, although in the last four months we’ve battery banks ever built.

They can’t make more product here in the U.S., so they have to import it. This has been a very interesting project for us. It combines our bulk material handling expertise, our machinery expertise, our dock and facility expertise all into one project. It’s something I’m very proud of.

JB: We recently supported OceanAero with their Triton platform, a sail- and solar-powered, autonomous unmanned surface vessel (USV). Our effort focused on modifying the wingsail geometry to improve sailing performance. Our

DLBA team collaborated with our new counterparts at Lei- dos to create a computerized routine to re? ne the geometry and evaluated the results using computational ? uid dy- namics (CFD). We achieved great results on paper and the new geometry test article is under fabrication, with testing scheduled for later this year. I’m proud of this project be- cause working with sail powered vessels is new for DLBA, and we were able to collaborate with new teammates, both internal and external. It’s relationships that lead to success, and it looks like this team’s initial effort will be a success.
