The various drilling operations; exploration and or plug & abandonment operations result in different types of slops. Most of this waste cannot be processed on the platform itself because its components are too complex to be treated with standardised preprogrammed equipment. Especially when waste streams are mixed together or stored for longer periods of time. This waste (slop) is therefore normally transported to an onshore treatment plant.
