WSOG and Emergency Disconnection Guidelines

OTC Brasil, 2017
Abstract Dynamic Positioning (DP) systems are becoming more and more used in the Oil and Gas Industry. Over the last decades, the escalation in deep-water exploration and development resulted in an increased number of dynamic positioned rigs.

A Deepwater Riser Emergency Disconnect Antirecoil System

Journal of Petroleum Technology, 1993
Summary During drilling in deep water, very high tensions must be used to control the riser, so a large amount of energy is stored in the riser and tensioning system. If the riser and stored energy are not controlled during an unplanned disconnect of the riser from the subsea blowout preventer (BOP), which would ...

Unplanned Disconnects in Deepwater Drilling: Prevention Measures and Emergency Response

SPE/IADC Drilling Conference, 2001
Abstract In 2000, two unplanned disconnects of the Lower Marine Riser Package (LMRP) occurred on deepwater rigs in the Gulf of Mexico. Both were attributed to human error. The IADC Deepwater Well Control Task Force reconvened to study this problem and investigate preventative measures.

Barrier Analysis of Emergency Disconnect on Dp Mobile Offshore Drilling Units

Volume 2A: Structures, Safety, and Reliability, 2020
Abstract Technical, operational and organization barrier elements related to the emergency disconnect on dynamically positioned mobile offshore drilling units on the Norwegian Continental Shelf are identified. Position loss scenarios are analyzed based on the published station-keeping incidents by IMCA (International Marine Contractors ...

Stopping, Emergency Stopping and Disconnecting Machines from Electricity

AUTOMATYKA, ELEKTRYKA, ZAKLOCENIA, 2020
The work highlights one of the most important aspects of machinery safety, which is stopping. Due to their specificity, the Machinery Directive distinguishes two stopping modes: normal (technological) and emergency, and separate disconnection from the power supply.

Methodology for Recoil Analysis of Emergency Disconnection Drilling Riser in a Deepwater Environment

Abu Dhabi International Petroleum Exhibition & Conference, 2019
Abstract In deepwater drilling, it is inevitable to disconnect the riser from the Low Marine Riser Package (LMRP) with the blowout preventer (BOP) under some extreme operating conditions. Since the riser is in tensile state under normal working conditions, elastic potential energy is stored in the riser.

Effect of Mud Shedding on Riser Anti-Recoil Control at Emergency Disconnect

Volume 3: Pipeline and Riser Technology, 2012
With drilling capability extends to water depths up to 3000m, significantly increased is the risk associated with a failed riser recoil control in the event of an emergency riser disconnect due to loss of vessel station keeping. In deeper waters the tensioner system undertakes higher top tension due to the accumulation of riser length and mud weight ...

A Systems Engineering Assessment of Emergency Disconnect System from the User Perspective

INCOSE International Symposium, 2018
AbstractThis paper assesses the decision‐making process for activation of the Emergency Disconnect Systems (EDS) on offshore rigs in the oil and gas domain. The industry strives to evolve to a higher level of autonomy. At the same time, the standards and regulations are falling behind.
