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. |
