Slop water
Slop water is produced on offshore oil and gas rigs when cleaning the pipe and drill deck and is water that is contaminated with hydrocarbons, other chemicals and wastes. On drill decks, slop water can also contain erosive substances such as highly corrosive salts, drilling muds including chemicals in suspension and in solution, mud containing water, salt water, rain water and formation water as well as sand, floating solids, stones and large particles.

All these various possible compositions make an overboard discharge of these slops inadmissible due to existing environmental regulations, so that they have to be treated before discharge. GEA offers a range of high-performance centrifugal separators and clarifying decanter centrifuges for the efficient treatment of slop water, reducing the oil content to less than or equal to 15 ppm. With the GEA solution, slop water can be treated on site, which avoids the traditional cost-intensive transport to shore for the necessary processing and disposal.
