OTG have developed a method for a detailed review of all planned drilling and well operations, involving personnel from Company and drilling contractor. The method is rig specific and based on Authority requirements and OLF 081 ”Anbefalte retningslinjer for fjernoperert rørhåndtering”.
The review includes information handling, offshore survey, HAZID meetings with risk classification and development of maps for red zones related to all identified operations summarized into the prevailing ”Red zone”. OTG red zone method has been implemented as ”best practice” by both Statoil and Dolphin. OTG have also developed a ”Red zone” software/application for easy information sharing/communication, follow-up and thorough quality assurance, DRMC Red Zone.
