Viphya on Lake Malawi.

Figure 4. Aerial view of the 160' drilling barge Viphya>/em> on Lake Malawi, where 26 members of the drill team, science team, and ship’s crew lived for six weeks. This fuel barge was converted to accommodate a 100 ton geotechnical drilling rig (capable of recovering sediment from >1 km below lake surface) and a dynamic positioning system to maintain the position of the drilling barge in waters too deep for anchoring.
