MOORING IN BASALTIC ROCK
Abstract
The operations are planned to include drilling three core holes in the pinnacle to obtain sample cores; grouting in rock bolts in the core holes to serve as moors, and testing one rock bolt to failure; laying a chain line axis along the site for the core holes for quick diver location; collecting rock samples (from any rock broken loose in coring or testing the one rock bolt); conducting extensive photography of all underwater operations; obtaining TV visual tape of coring and failure test, and updating the site survey data, particularly in the northwest quadrant, the latter as opportunity permits.
