Stork’s Advanced Online Desanding (AOD) system, now in its 3rd generation, sets a new standard for sand management that’s safe, environmentally friendly and cost effective. AOD removes and cleans sand from live separators without causing undue process disturbance or production loss ready for safe overboard discharge.
Using a thermographic camera, Stork determines sand accumulation in an online separator. Sand is then removed, cleaned and discharged back into the sea with no deferred production.
Desanding systems are not new, but Stork has raised the bar - to 60 Bar separator pressure to be exact - and in 90°C temperatures. AOD is not just tough but fast, capable of removing and washing 20-tonne of sand per day. With solids separation effective for minute particle sizes - 10 to 500 microns, AOD is also highly precise, the company said.
AOD ensures offshore sand disposals are in line with environmental discharge limits while eliminating the cost of onshore waste clean-up. Oil contamination from recovered solids is removed to less than 1% oil content prior to overboard discharge and costs of onshore clean-up are therefore eliminated.
