A Study on the Holding Ability of Anchors for large Vessel
Haruo SATO, Takashi KAWACHI and Tomoki NOJIN
Abstract
The holding ability of three types of anchors was examined in relation to the resistance against the towing rope
set at various angles.Experiments were performed using three type anchors (JIS type,AC-14type and DA-1type).
These anchors were pulled using the Research Vessel, HOKUTO (19T). The tension force was measured using a
loadcell connected to the towing rope. The experimental results indicated that the DA-1 type anchor showed the
highest resistance and the most stable performance, and the JIS type anchor showed the lowest resistance.
