    Offshore Overboard Discharge

    Offshore facilities are crucibles of technology. Topside producers face difficult operating conditions, limited space, long supply chains, and strict environmental discharge factors. Production curtailment or shut-in is a very real consequence of underperforming water treatment equipment.

    MYCELX addresses these issues with tertiary polisher technology that acts as an insurance policy enabling overboard discharge in the most difficult operating conditions. No production is lost while meeting environmental regulations.

Common Problems

Most in-place water treatment equipment on facilities are designed for maximum expected throughput. Frequently, prolonged upsets put conventional treatment units that rely on gravity separation techniques at a disadvantage.

  • Disruptive flow (slugging) frequently occur during complex subsea topside operations
  • Mechanical failure in upstream treatment equipment that does not have redundant capacity
  • Chemical injections for flow assurance (hydrate inhibition, corrosion inhibitor, etc.) cause emulsion issues-hampering treatment from conventional technologies
  • High motion events, or weather caused by shut-ins lead to cold start-ups and other special situations and cold starts
  • Lack of turndown flexibility during early production

Solutions

MYCELX Polisher systems have been successfully deployed on deep and ultra-deepwater floating facilities treating discharge water since 2011. The polisher can be installed as a stand-alone system or as a bolt-on to underperforming existing treatment trains boosting performance and enabling continuous discharge and operations. Addition of a controls package enables intermittent use of the Polisher as an insurance policy during excursions and upstream equipment failures.

Benefits

  • Fail-safe performance
  • Smaller footprint
  • Simple operation
  • Turndown capability
  • Lower, safer maintenance
