||Noble Denton Marine Services Ltd., Moray House, 145 Crown Street, Aberdeen AB1 2HR, United Kingdom, Mar. 1991. 125p. Illus. 25 ref.
||This report describes the results of a risk study in which event tree analysis was used to investigate the consequences of mooring failure for Mobile Offshore Drilling Units (MODUs). The following possible consequences of mooring failure were studied: collision with an existing installation; blowout; pipeline fracture; tripping capsize; stranding or grounding. It was concluded that the greatest risk associated with station keeping system failure is that due to the possibility of a collision with another installation. The greatest risk associated with single line failure is that due to possibility of damage to the marine riser of B.O.P. leading to an uncontrollable escape of hydrocarbon.
