Waste Water Treatment Unit


OTS Waste water Treatment Unit History.

The first mechanical waste water treatment unit for the completion phase in the North Sea was installed by Offshore Technical Services A/S and operated by Baker Oil Tools onboard the Transocean Searcher operated by Statoil on the Aasgard field in early 2001. The idea was to come up with some mechanical separation to replace the flocculation and filtration process.

After using it for 8 wells Statoil evaluated the result using the waste water treatment unit and prove that they with the new technology had an average saving on 2 million Nok each well compare to the other technology used on previous wells.

By end of the year 2001 Offshore Technical Services A/S was nominated for the chief executives HSE prize for 2001 in the Statoil system for the waste water treatment unit.

End of 2006 the cooperation and the contract between Baker Oil Tools and Offshore Technical Services A/S within waste water was closed. Offshore Technical Services A/S did then continue to improve the waste water system by installing one complete test unit on the washing bay area in Tananger to test and to optimize the system with different fluids.

The experience gain from the washing bay was transferred to Pieralisi engineering department and into our new offshore units.

The new system was ending up with a large improvement from the first existing units and also now with new machines tailor made for the operation.


In 2010 Offshore Technical Services A/S did start producing the new generation waste water treatment units for the Norwegian offshore marked. Today our unit has a good proven track record in the North Sea through different service companys and operator.

Through our company Scottech located in Perth in Australia we did a trial with one unit on 6 month for the Australian oil company Woodside.

After the trial Woodside decide to keep the unit onboard the Atwood Eagle. Feedback so far is excellent piece of equipment proving very good results.


Such feedbacks are very pleasant to receive, but also feedback from operators on day to day problems they meet during operation and maintenance of the units are more than welcome such we are able together to develop the system further.
