Accident took place somewhere between Britain and Ireland. Time of accident 1 o’ clock in the morning; seas were heavy but not eccesssive. Ship was empty of load, but tanks were cleaned of fumes. It was ballasted according to specification of builders. Centre tanks were full, with some wing tanks about midships. Oil fuel was carried at the fore end tanks well at the aft end near engine room. Quantities of water also carried; general loading seemed to be disposed according to hogging conditions. Ship was traveling against the weather. Machinery was composed of main turbine (H.P. with astern wheel on), two turbogenerators, three centrifugal cargo pumps, one diesel electric, steam driven pumps for ballast, domestic, feed etc, condenser, preheaters, evaporators, compressors etc; two boilers were completing the engine room equipment (boilers air - fuel requirements according to steam pressure were automatically adjusted). The propeller was 4 - bladed. Machinery did not give in the past any vibration troubles; chief engineer thought actually that she was running in a smoother than what previous experience in other tankers of the same size has tought him. Under load conditions in calm water ship was said to sag about 6΄΄ amidships; in rough weather she was said to distort longitudinally. In the night of the accident propeller was running at about 90 rpm, but speed was subsequently reduced due to increasing vibration in the engine room. At the moment of the accident the speed was about 60 rpm. A big wave struck the ship at the bow. She was cut in two, aft of the bridge and fore of the two derricks. At that time most people were sleeping and did not hear any noise; one man did not understand anything at all until he saw the fore part of the ship from his port hole (he was not asleep). Captain at the bridge did hear the noise. In the engine room no noise was heard but platform started vibrating violently in an 152
