The competitive bid process was used to evaluate the top 5 shortlisted vendors, in conjunction with a technical evaluation by Shell internal water treatment subject matter experts. The options matrix evaluation tool was used to narrow the list further to Veolia and Vacom as the top 2 shortlisted vendors for further technical investigation and final economic feasibility. GE was evaluated and removed from the list due to higher operating costs, directionally higher operator intervention requirements to maintain the system, and the requirement for more interfaces between GE and an environmental EP to design peripheral components of the system. Saltworks and Saltech are less mature companies with less experience in the oil and gas market, with higher operating costs and much smaller unit trains which would result in 2-3 times more equipment to operate per m3 of feed. Vacom was identified as the lowest capital and best operating philosophy with least potential for ongoing scaling and fouling, however it had one show stopper associated with a requirement to run a boiler on a continuous basis. This was further challenged and eliminated from the scope, by incorporating another means of heat input. Vacom was therefore selected as the preferred vendor of choice for the water treatment package.
