Oil industry cleaning process nets innovation award

advance in cleaningmaking a huge differ- ence in efficiency and safety,” said Stephen Kerr, regional sales leader for UK, Ireland, Nordic and Benelux at Kimberly-Clark Pro- fessional. “Cape Environmental Services has responded to a challenge froma high- tech, high efficiency industry and I congrat- ulate themon a well deserved win.” Stephen Vickers, regional director re-

sponsible for the UK CES at Cape, said: “Being recognised by the judging panel at the Golden Service Awards for the work carried out by Cape Environmental Services on BP’s North Sea ETAP platformis testa- ment to the high quality, safe services we provide to our clients in the oil and gas in- dustry.

Syphonvac VI sand removal system. Syphonvac VI allows operators to continue hydrocarbon recovery activities during sand removal from production vessels, avoiding the requirement for costly shut- downs previously associated with tank cleaning processes. Cape, which recently received a RoSPA

gold standard award for safety, has an in- ternational reputation for pioneering a wide range of safe, environmentally sound in- dustrial cleaning techniques. These are de- signed to increase exploration and production efficiency while reducing poten- tial environmental risk. “Cape Environmental Services developed

Syphonvac to facilitate the online removal of sand fromproduction vessels without the requirement for production shutdown or confined-space entry to the vessel by personnel - significantly improving effi- ciency and safety,” continued Vickers. “Syphonvac was created specifically to im- prove production within the supply chain and it has been received incredibly well throughout the industry, with its deploy- ment on ETAP delivering significant time savings to the operator.” BP engaged Cape Environmental Serv-

ices to install and operate the Syphonvac systemto the LP Separator on the ETAP platformin the Eastern Trough Area of the UKCS North Sea. Cape Environmental Services removed almost three tonnes of sand throughout the process, with the ves- sel remaining in full production for the du- ration of the procedure. Time saving achieved by this procedure was approxi- mately 17 days in the turnaround period.

Further benefits have also been realised, with oil/water separation improved and a reduction in the volume of sand carrying over through the produced water process. LovatMacGregor, business development

manager at Cape Environmental Services Offshore, explained why the processmakes such a difference: “Themajority of hydro- carbon reserves are contained in sandstone reservoirs, where sand production is likely to become a problemat some point during the production life of an oil or gas field. When oil or gas are produced fromrela- tively weak reservoir rocks, small particles and sand grains are displaced and enter the fluid flow - up to several tonnes of sand per day.” The speed at which the fluid is travelling

is typically high enough to bring sand up through the well pipeline to the platform topside where it accumulates in production separator vessels and production process pipelines. “Produced sand is detrimental for several

key reasons,” continuedMacGregor. “When it reaches the surface, the abrasive nature of the sand can damage valves, pipelines, pumps and separator vessels and, when a significant volume of sand collects in sepa- ration vessels, the capacity of the separator to process oil, gas and water is reduced.” In the past, wells have been shut down to

allow the separation vessels to be opened and the sandmanually removed. “A critical path shutdown operation will be required and, as a consequence, deferred produc- tion costs are likely for operators and the supply chain,” saidMacGregor. “At Cape Environmental Services, online sand re-
