New BOP Concept from JL Daeschler

Posted in drilling, well control incidents, tagged , , on May 2, 2011| Leave a Comment »

JL Daeschler, subsea engineer and inventor, sent me some preliminary drawings for a new BOP concept.

  • JL’s design concept is based on 2 slab gate valves, one above the other, that move in the opposite direction and are beveled for shearing.
  • The sealing element is fixed (solid, one-piece) to the main body of the BOP, does not move with the rams, and is fully protected in the drilling mode.
  • The hydraulic system would retract the gate rather than close it (fail-safe closed).
  • The upper and lower rams (gate valve type) are self-centered with a guiding system to minimize side movement and deflection.
  • Well pressure assists in forcing the upper ram against the sealing element.
  • JL is considering a similar concept (single shear) for xmas tree workover system.

JL Daeschler – Offshore Engineer and Artist

Posted in Uncategorized, tagged , on February 11, 2011| Leave a Comment »

JL Daeschler, one of our astute commenters on offshore safety issues, is a subsea engineer with vast international experience. He holds patents for seabed drilling templates and subsea control systems, and has worked all over the world on offshore projects.

JL is also an accomplished artist who has exhibited in Paris, le Havre, Singapore, Houston, Edinburgh, and Calgary. He works mainly with acrylics, and his preferred subjects are boats, maritime scenes, harbors and the working environment associated with the sea.

Sometime he combines his interests. “Waiting on Weather” (below) was published in a book about North Sea oil development. Below that are an impressionistic offshore platform painting, an extraordinary coastal sunset scene that my wife really liked, and one of JL’s exciting America’s Cup paintings. Click on any of the paintings for enlarged images.

Mr. Daeschler was raised in France, has traveled the world, and currently lives on the coast of Scotland.
