A leading drilling contractor has selected Reel Power Marine & Energy Depth Compensated Accumulators (DCBs) to retrofit to their Semisub deepwater drilling rig to increase available volume. The contract required more stringent sheering capabilities than existing equipment could handle. Adding additional conventional bottles was ruled out because of available space on the BOP. Several alternates for increasing volume were considered, but in the end DCBs were selected. The DCBs have proven to be extremely reliable with hundreds in operation and offer other advantages, including lower maintenance due to less equipment requirements and lower weight and space requirements due to high efficiencies especially at deeper water depths. In addition, once the nitrogen pre-charge is set, you don’t have to worry about changing for various water depths, saving non-productive time setting the pre-charge as well as minimizing calculations and personnel intervention. The DCBs are great for stack hopping!
Reel Power Marine & Energy DCBs are available for any make of deepwater BOPs. Please contact us if you need more volume or to improve your subsea equipment operation.
