A Study on The Holding Capacity of Anchors
Haruo SATO
Abstract
The holding capacity of three types of anchor was examined in relation to the sand content of the seabed. Experiments were performed using three stockless type anchors (JIS type, AC-14 type and DA-1 type). These anchors were pulled using the Research Vessels,HOKUTO (19t). The tension force was measured using a loadcell connected to the towing rope.The sand content of the seabed was chosen as an index property,and was correlated to the holding capacity.The experimental results indicated that the DA-1type-stockless anchor showed the highest resistance against pulling for clayey and good holding capacity for sandy soils,and the AC-14type-stockless anchor showed the highest resistance against pulling for sandy and sandy clay soils. The DA-1type-stockless anchor can be used for anchoring vessels.
