Weir’s WMSS10 Mudline Suspension System transfers the weight of the well to the seabed. It offers a method of disconnect for all casing strings, allowing the temporary abandonment of a well in a minimum amount of time and without having to cut casings. Casing strings can be easily reconnected for surface completion on a production platform wellhead deck.
The WMSS10 Mudline Suspension System features a series of hangers with landing and load rings located on load shoulders to transfer the weight of each casing string to the conductor and the seabed while drilling from a jack-up.
“The introduction of our WMSS10 Mudline Suspension System enhances our product offering and enables us to offer a complete wellhead related equipment solution,” said Gordon Cameron, President of Weir Oil & Gas Pressure Control for the Eastern Hemisphere.
The WMSS10 is designed for high-capacity casing hang-off loads and high pressure STD and H2S wells to allow operators to run casings to deeper depths. The stack-down configuration provides a washout point below the previous sealing area.
Metal-to-metal sealing protects against high pressures and corrosive fluids while separate running and tieback threads offer protection during drilling and temporary well abandonment. Generous flow-by areas maximise circulation during the cementation process. Additionally, generous washout ports in the running tool eliminate cement contamination. Long lead-in allows for self-aligned easy stabbing.
The standard casing configuration is 30 in. x 20 in. x 13-3/8 in. x 9-5/8 in. with 10 000 psi working pressure for STD and H2S application.
