Abstract: A method for providing positive pressure to an interior of a positive pressure facility can use an HVAC system. The method can include securing an enclosure to an exterior of the positive pressure facility, pulling fresh air from outside of the enclosure into an evaporator compartment to form conditioned air, transferring the conditioned air from the enclosure to an enclosure extension attached to the interior, and flowing the conditioned air into the interior. The method can include receiving air from the interior into the enclosure extension, determining a differential pressure between a pressure outside and a pressure of the interior, and maintaining positive pressure in the interior using the differential pressure, a process control unit, the conditioned air, and a human machine interface. The human machine interface can determine present various real-time values, control buttons, and screens for operating the HVAC system.

Abstract: A client configuration tool configured to program a universal master control station to allow expansion of an existing oil field, monitoring and controlling of subsea/topside field equipment provided by multiple vendors, or combinations thereof.

Abstract: A method for controlling subsea components from multiple manufacturers, each having a proprietary communication interface. The method can include creating a graphical representation of a production system to be controlled by a universal master control station, setting control sequences for the system, creating a script for comprising control code for a universal master control station associated with subsea/topside equipment at a field, and configuring the universal master control station using the script.

Abstract: A system for providing positive pressure to an interior of a positive pressure facility can include an enclosure for securing to an exterior of the positive pressure facility, an evaporator motor compartment with a motor, a compressor compartment with a compressor, a fresh air intake section for bringing air in from outside, a condenser compartment with air venture, a heater compartment with a heater, and an enclosure extension for attaching to the interior of the positive pressure facility. An electrical compartment can be connected with a return air compartment of the enclosure extension. A human machine interface with a display can present controls for controlling the system and various portions of real-time information related to the system.

Abstract: A system for controlling subsea components from multiple manufacturers, each having a proprietary communication interface. The system can include a client configuration processor. The client configuration processor can communicate with a client configuration data storage. The client configuration data storage can include a human machine interface client configuration tool and an engineering client configuration tool.
