The Management of Hazards during Pinned to Seabed Operations

This article presents a review of the current industry approach to the perception of risk and the managment of the hazards on a floating rig or vessel connected at the seabed. The range of possible consequences covers everything from minor operational delay to catastrophic failure of the workstring. This article includes two first-hand accounts of events that resulted in severe damage to the rig structure and also incorporates feedback from a survey of subject matter specialists to gauge a wider understanding of industry incidents and perception of risk.

Nick and Paul give you what you need to confidently supervise and manage a Well Test Operation from a high level. Given their combined years of experience in the area, they walk their talk. Few times I have left a training course feeling so confident and getting exactly what I expected from it. Being run through engineering theory, field application, HSE, operations, equipment, procedures, field tricks and how to read between the lines, clearly tells me that they listened to my expectations when we walked into the room on day 1. Highly recommended!
