PERFORMANCE TESTS OF DRILLING-VESSEL ANCHORS

Holding-power tests on several types of anchors in a variety of mud and sand bottoms revealed varying degrees of reliability. Balling up and failure to dig in were the principal problems encountered. A new streamlined anchor, the BOSS, generally out-performed the others by digging in quickly, holding well, and avoiding ball-up. The paper describes tests conducted in the Gulf of Mexico on model anchors and on full-sized anchors. Two large anchors (22,000 lb) were tested and used in the Santa Barbara Channel and in the Bass Straight, Australia. (Author)
