THE CHALLENGE
A major North Sea operator required support with their waste/ullage management while running a platform shutdown. To avoid incurring extensive commercial and environmental costs for the fluid waste transportation back to shore they elected for a solutions that enabled the volumes of fluid to be treated at source.
HOW WE HELPED:
OSSO was selected to facilitate the full clean down of the residual treated seawater which contained trace hydrocarbons. As part of the process all fluid waste was routed to a miscellaneous tank, where polishing, oil, water and solids separation occurred.
To ensure the levels were correct and within legal limits for overboard discharging, fluid analysis was carried out at a regular intervals through the duration of the project.
STRONG RESULTS:
The fluids were separated and cleaned to <30ppm allowing for overboard discharge. In total 273m³ of volume was discharged, averaging close to 100% of the overall fluids processed. Not considering the logistical and personnel costs associated skip and ship, this process enabled an average cost saving of £600per/tonne for the Operator. By utilising the mechanical separation technique, OSSO further reduced wastage by removing the need for filters.
