Diver-deployed

Diver-Deployed SeaDog and Initial Integration with the REMUS... 

The REMUS sensor suite was also configured for diver deployment (Fig. 6.6). The sensor module was easily detachable from the REMUS and could be mounted...

Test results for the diver-deployed and initial REMUS-deployed sensor tests are presented in Section 6.5.2.

Diver-deployed BMFCs are an option for shallow water deployments (typically <30-50 m) where depths are not prohibitive to diving and the size of the BMFC can be handled easily by one or two people in the water (i.e., BMFC systems requiring sediment displacement of volumes <0.5 m ). BMFC systems larger than this require large teams of divers, which become cost prohibitive to deploy on the basis of labor costs for the deployment team to properly handle, place, and bury the anodes. 

Sealed Booms. The sealed boom is a modified form of the containment boom that extends the skirt of the boom as much as 25 ft into the water. Heavy chain extends along the entire length of the bottom of the boom skirt, and carbon dioxide-activated anchor points are used to drive the chain into soft mud or sand. Divers are used to discharge the carbon dioxide cartridges and ensure that the chain provides a good seal on the bottom of the waterway. Expense, deployment time, subsurface debris, hard bottom substrates, moving water, and excessive water depths are major drawbacks to this method.
