Achieving at Source Cleaning for the First Time - Case Study
Improved slops and liquid waste management process
UK, North Sea
Achieving an operational slops system at source for the first time
While feeding the centrifuge with a port slop pump, surging of fluid was observed, which meant it was not possible to achieve a stable flowrate, to overcome this a back pressure was introduced on the slop water return line.
This was the first time our client had a fully functioning slops system on board their FPSO allowing them to treat slops at source. Our inspection results post installation found all valves and functions to be working correctly. By implementing such a system enabled our client to realise long term commercial and environmental benefits. All works were carried out on time, without any LTIs and within budget.
- Improved wastewater treatment
- Reduced wastewater environmental and commercial burdens
- Future recommendations for continued improvement
- Zero LTIs
Our client, a UK operator, required their slops units to be operational prior to seeing first oil. To achieve this meant working to a compressed timeframe and delivering a solution that would enable all slops to be cleaned “at source”, which had previously not been thought possible.
HOW WE HELPED:
The slop water centrifuge was installed in the shipyard but was never fully commissioned. To get the slop water centrifuge back up to operational readiness, a detailed survey was conducted, allowing us to identify all underlying issues. From here we removed and replaced all corroded parts including valves, O-rings, spindles and more.
The control system had to be commissioned from a nonfunctioning state to fully operational including integration with central control room.
