A typical subsea deepwater blowout preventer system includes components such as electrical and hydraulic lines, control pods, hydraulic accumulators, test valve, kill and choke lines and valves, riser joint, hydraulic connectors, and a support frame. Two categories of blowout preventer are most prevalent: ram and annular. BOP stacks frequently ...
Marine engineering company Oceaneering yesterday announced it had secured contracts with a subsidiary of Transocean to provide three subsea blowout preventer control systems that will add more ...
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed. [1] Modern wells have blowout preventers intended to prevent such an occurrence. An accidental spark during a blowout can lead to a catastrophic oil or gas fire.
The Lower Riser Package is a mechanical device to protect an oil well located underwater (subsea) and used during an oil well intervention. The LRP is essentially a mini blow out preventer (BOP). The lower riser package consists of a connector to the subsea oil well, a series of safety valves and a connection point at the top for connection to ...
Failure of blowout preventer equipment was a major cause of the April 2010 disaster that killed 11 workers and resulted in an estimated 130 million gallons of crude oil spewing into the Gulf of ...
BP (BP) said Friday that the Deepwater Horizon rig's blowout preventer, which failed to prevent oil from the Macondo well from flowing into the Gulf of Mexico, has been removed from atop the well.
June 22 – Mark E. Hafle, a senior drilling engineer at BP, warns that the metal casing for the blowout preventer might collapse under high pressure. [10] October 7 – The Transocean Marianas semi-submersible rig begins drilling the Macondo well. [11] November 9 – Hurricane Ida damages Transocean Marianas enough that it has to be replaced. [11]
Drilling riser joints with buoyancy modules. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally ...
