The project examined the Loss of MODU Station-keeping in the Gulf of Mexico
during Hurricane Ivan, September 2004, comparing those findings with that of
recent Hurricanes Andrew (1992) and Lili (2002), and assessed the current
mooring standards and criteria to prevent similar failures.
Objectives:
The project’s objectives are summarized
below:
1. Study the failures
associated with the Mobile Drilling Units during Hurricane Ivan including
gathering and reviewing information and determining cause available on:
a. Loss of station
keeping of 5 Semisubmersible MODUs
b. Collapse of a
jackup MODU.
c. Damage to 2 other
jackup MODUs
d. Settlement on the
legs of one or more other MODUS which could have resulted in casualties.
2. Develop any
recommended update on criteria and perform analysis determining if the
updated criteria would have caused these units to avoid the resulting effect
during the hurricane.
3. Re-visit the
Recommendations from the Hurricane Andrew and Hurricane Lili Studies on
station keeping, and update any recommendations for future mitigation
action.
4. Make
Recommendations as to how the criteria for siting jackups would view these
jackup MODUs at their locations and make any recommendations for future
mitigation action. |
