In early April 1996, the Minerals Management Service (MMS) began granting departures for testing BOP equipment on a 14-day interval. The purpose for these departures was to gather data on BOP performance. The MMS and five oil and gas trade organizations hired a contractor to analyze these data and prepare a report on BOP performance. The MMS will use the study to determine if a 14-day test interval provides an equal or better degree of protection, safety, and performance when compared to the current requirement for a 7-day test interval.

Certain potential adverse environmental effects have been recognized in the use of polychlorinated biphenyls (PCB's) in liquid heat transfer units. Until recently, the impact of the introduction of PCB's to the environment has gone unnoticed. However, present research on PCB's has indicated them to be chronically toxic to the ecosystem.

A flash fire occurred in the production facilities of a producing platform in OCS waters directly resulting from the ignition of fluid from the heat transfer unit. The liquid phase heat transfer system was being used for heating oil to separate water through a chemical-electric treater. It was also to be used as the heating medium for the glycol system to separate water from gas but that system was not in operation.
