"Our team has finally reached sump 7 and camp 2 where we are using our Hennessy Hammocks. Before any exploration dives can take place the team need to bolt and rig the 70m pitch down to the water and install a portaledge at the bottom of the shaft. Using the portaledge our divers will be able to assemble their kit before heading off on deep dives. The portaledge will also play an important role after each dive. Our divers will need to wait here for several hours whilst off gassing before exerting themselves with the long prussik up the shaft back to camp. "
