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.

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.
The fluids were separated and cleaned to
- Discharged 273m³ at source
- Supported the overall TAR plan/schedule
- Reduced resource constrains for the client
- Generated average cost saving of £600 per/tonne
- >95% processed fluids discharged at source
