 The anti-terrorism force protection barriers in Augusta Bay, Sicily, are inspected every three years. This task is carried out by members of the underwater construction team, a small group of diver-qualified sea bees. Builder First Class Joseph Bickham tells us the reason for these inspections. Sea life tends to gravitate towards the chain. It gives them something to grab on to. You think the steel is a pretty hard piece of equipment down there on the bottom of the ocean, but with all that rockin' and rollin' that the ocean does, you'll see a two-inch chain get down to a toothpick sometimes, and it's pretty impressive. Team members spend two weeks in Augusta Bay performing the inspections, using brushes, hammers and chisels to clear debris from the chains and anchors that hold the barriers in place. Once they get a good clean chain, we have a tool. It's a calibrated device. It's a go-no-go gauge, and it'll show us greater than 90% of the diameter of the chain, or less than 80% of the diameter of the chain, and that's the data we use to send forward to the engineer. Bickham admits that the schooling was tough, but he welcomes the challenges that come with being a diver and is happy with his choice to become a member of the underwater construction team. I enjoy being a construction worker, a builder, so I still get to use my skills on a day-to-day basis when we're out to sea and on deployment and stuff. And then the diving side of it is just a whole other aspect, you know. I got paid to go diving today in Augusta Bay, so it feels really good.
