Expedient Deep-Water Propellant Anchor Mooring System.
Abstract
The Civil Engineering Laboratory has investigated the best means for installing CEL 20K Propellant Anchor quickly, effectively, and efficiently in the seafloor. This anchor can achieve holding capacities of 20,000 pounds in water depths of 20,000 feet. Several concepts were examined for launching the anchor system and deploying the anchor and line. Also included were advanced concepts for laterally distant anchor deployment. Alternate components were identified, and candidate systems were synthesized and evaluated. A buoy-launchable, free-falling, bale-on-anchor system was selected as best satisfying the broadest range of foreseeable needs. Preliminary design information is given for this 'standard expedient mooring system package.' The system includes a feature for automatic length adjustment, stopping, and locking of the line at the anchor to provide a taut surface moor; this feature can be deleted to reduce cost. The package can be towed to a site or launched from a suitable carrier. A launching system is described that permits the proposed package to be launched from most surface vessels having an open cargo deck capable of accommodating the size and weight of the package; no ship-borne load-handling equipment is required.
