Influence of operability criteria limiting values on ship speed
Prpic-Orsic, Jasna; Faltinsen, Odd Magnus; Parunov, Joško (Journal article; Peer reviewed, 2016)When the ship is caught in heavy seas, there are two manoeuvres that the shipmaster can undertake to avoid excessive ship motion and hull damage: changing course or voluntary speed reduction. This paper presents a study ... -
