From the article:
It was during this call that “Transocean elected to stay connected to the well because previous sister drillships in similar conditions (Category 1 Hurricane Conditions) rode out storms without issues,” the report said.
That sounds more like coming up with a justification for the outcome they wanted rather than sound storm avoidance policy. Anyway, old policy: lets ride it out. New policy: move if in the path of a hurricane.
Also from the article:
BSEE stated that the probable cause of the accident was “an inaccurate weather forecast, with a key contributing cause being the human error decision to stay latched to the well to attempt to ride out the hurricane.”
While forecasts predicted that Hurricane Zeta would pass east of the Asgard, the drillship took a direct hit from the hurricane with sustained 90 to 100 miles per hour winds, equivalent to a strong Category 1 and Category 2 hurricane, and seas up to 30 feet. A peak wind gust on the derrick was even clocked at 152 mph.
The NHC puts out a report every year for each storm summarizing each hurricane forecast, here is the report on Zeta
