A floating vessel with a filtration and testing device for simultaneously performing (a) cleaning of fluid used in oil and natural gas industry for completions, workovers, and commissioning of wells, (b) pressure testing of a first group of pressurized equipment using fluid cleaned by the filtration and testing device, and (c) pressure testing of a second group of pressurized equipment using fluid cleaned by the filtration and testing device, the floating vessel comprising:
- a. a hull;
- b. a support structure mounted to the hull, the support structure containing:
- i. a cleaning cycle assembly comprising:
- (a) a pump receiving:
- low pressure air from a low pressure air supply actuating the pump and wherein the actuated pump sequentially pulls:
- (i) a first dirty hydraulic fluid from a first dirty hydraulic fluid supply;
- and
- (ii) a second dirty hydraulic fluid from a second dirty hydraulic fluid supply;
- (b) a multistage filtration device fluidly connected to the receiving the first or second dirty hydraulic fluid from the pump and producing a cleaned hydraulic fluid;
- ii. a pressure testing cycle assembly comprising:
- (a) a low pressure hydraulic fluid pump receiving a low pressure air from the low pressure air supply and receiving a cleaned hydraulic fluid from the cleaning cycle assembly and pumping a low pressure cleaned hydraulic fluid;
- (b) a high pressure hydraulic fluid pump receiving a low pressure air from the low pressure air supply and receiving a cleaned hydraulic fluid from the cleaning cycle assembly and pumping high pressure cleaned hydraulic fluid;
- (c) a low pressure fluid pump receiving a low pressure air from the low pressure air supply and receiving a secondary low pressure fluid from a fluid supply and pumping a low pressure fluid;
- (d) a high pressure fluid pump receiving a low pressure air from the low pressure air supply and receiving a secondary high pressure fluid from the fluid supply and pumping a high pressure fluid;
- and
- iii. a controller connected to each of the fluid pumps for regulating pressure of the low and high pressure cleaned hydraulic fluids and the low pressure and high pressure secondary fluids, the controller comprising:
- (a) a low pressure cleaned hydraulic control section comparing to preset limits, the pressure of the low pressure air and low pressure cleaned hydraulic fluid;
- (b) a high pressure cleaned hydraulic control section comparing to preset limits, the pressure of the low pressure air and high pressure cleaned hydraulic fluid;
- (c) a low pressure secondary fluid control section comparing to preset limits, the pressure of the low pressure air and secondary low pressure fluid;
- (d) a high pressure secondary fluid control section comparing to preset limits, the pressure of the low pressure air and secondary high pressure fluid;
- and
- wherein the controller simultaneously (i) regulates the cleaning of the first and second dirty hydraulic fluids;
- (ii) regulates the flow of air and pressure of:
- high and low pressure cleaned hydraulic fluids for pressure testing of the first group of pressurized equipment, and (iii) regulates the flow of air and pressure of high and low pressure secondary fluids for pressure testing of the second group of pressurized equipment.
