The STATO mooring anchors were designed to be used in (1) permanent mooring such as Fleet moorings, or (2) in situations where large holding powers are required such as in salvage operations, or (3) in the temporary mooring of large barges or vessels. In-service tests were requested by the Naval Facilities Engineering Command to determine any adverse operational characteristics which might become apparent through varying or continuous operational use. STATO anchors were substituted for Navy Stockless anchors of equivalent holding power already attached to two Fleet mooring assemblies of different capacities in the Navy Harbor Complex in San Diego Bay during the regular Public Works Center inspection of moorings. This report describes the fabrication and installation of the anchors and the results of a 1-year operation. The anchors were removed from the water and inspected after the test period. The results of the evaluation showed no adverse operational characteristics and that the anchors performed satisfactorily. (Author).

A new Navy mooring anchor (NAVMOOR), has been designed to satisfy a variety of Navy anchor applications. Various sizes of anchors have been designed, fabricated, and structurally and operationally proof-tested. This report describes the NAVMOOR Anchor, presents the results of prototype single and tandem anchor tests and sand and mud seafloors, provides anchor performance specifications, and presents Navy fleet mooring anchoring guidelines. The NAVMOOR Anchor was shown to be structurally and operationally superior to the Navy's STATO Anchor which in the past was the most effective general purpose anchor for Navy applications. The NAVMOOR Anchor was effective in dense sand and soft mud seafloors when used in single and tandem anchor leg configurations. Tandem anchor system holding capacity was shown to be at least twice the capacity of a single NAVMOOR Anchor. The Navy's fleet mooring requirements from class C (100-kip capacity) to class AA (500-kip capacity) can be satisfied with only two sizes of NAVMOOR Anchor, the 10,000-pound and 15,000-pound NAVMOOR, used in various single and tandem anchor leg configurations.
