Period

BETWEEN 1976 & 1982

Canada

THE OCEAN RANGER DRILLING PLATFORM & ALL 84 CREW MEMBERS WERE LOST DURING A STORM FED. 15, 1982. PORTLIGHT #4 BROKE DURING THE EARLY HOURS OF THE STORM, PERMITTING WATER TO ENTER THE BALLEST CONTROL ROOM & WET THE CONTROL PANEL. THIS ACT INITIATED THE SEQUENCE OF EVENTS WHICH LED TO THE DISASTER. HAD THE DEADLIGHTS BEEN CLOSED, AS THEY SHOULD HAVE BEEN IN STORM CONDITIONS, THE LOSS COULD HAVE BEEN PREVENTED.

Function

FOUR PORTHOLES ALLOWED BALLEST CONTROL ROOM OPERATOR TO OBSERVE SUPPLYVESSELS DURING THE TRANSFER OF CARGO & TO VIEW DRAFT MARKS ATTACHED TO THE FOURCORNER COLUMNS. THE PRIMARY REASON FOR LOCATING THE BALLAST CONTROL ROOM IN THETHIRD STARBOARD COLUMN WAS SO THE BALLEST CONTROL OPERATOR COULD READ THE DRAFTMARKS (P.17)

Technical

WHEN IT WAS LAUNCHED IN 1976 THE OCEAN RANGER WAS THE LARGEST, SELF-PROPELLED SEMISUBMERSIBLE OFFSHORE DRILLING UNIT IN THE WORLD. (REPORT p. vii)
