Emergency Disconnection Guidelines [PDF]

OTC Brasil, 2013
Abstract The construction of petroleum wells is becoming more and more complex and challenger. Drilling and completion in deep and ultra deep water requires use of dynamic positioning rigs increasingly sophisticated. Despite all the technology, an emergency disconnection may occurs at any time in dynamic positioning

Study on mud discharge after emergency disconnection of deepwater drilling risers

Journal of Petroleum Science and Engineering, 2020
Abstract Mud is often discharged into seawater after emergency disconnection of risers in offshore oil and gas drilling engineering. The discharged mud needs to be simulated accurately since it can produce a huge load on risers. Several mud discharge models have been proposed, such as Young's slug model, SFM model, WFC model and one-dimensional ...

Improved recoil dynamic analysis of the deepwater riser system after emergency disconnection

Applied Ocean Research, 2021
Abstract The riser recoil after emergency disconnection is a complicated multi-coupling process. However, most existing analytical models simplify the tensioner as a constant stiffness spring, divide the riser system into different finite element segments, and do not consider the coupling effect between the riser movement and the fluid discharge.
