The AlphaPRIME™ System-Modules are the heart of the AlphaPRIME™ CPU. The design allows for the System-Modules to be installed, and configured suitable for early field life, and then reconfigured later to take account of changing reservoir characteristics such as reduced reservoir pressure, thus permitting CAPEX to be committed only when needed - hence, a "Just-in-Time" project management scheme can be adopted.

Each AlphaPRIME™ CPU contains a minimum of two System-Modules to ensure maximum system availability in the event of a malfunction. The System-Modules are state of the art, all-electric, unitised autonomous units that can be configured with a variety of equipment to suit particular field processing requirements. The System- Modules have been designed with a minimum of wet-mateable fluid, power and controls connectors to enable them to be readily removed or replaced. As such, the modules can be reconfigured at any point during field life to suit changing reservoir characteristics and pre-tested prior to installation.

Each System-Module can be sized to provide up to 100% production throughput, and can include processing equipment, system control, power distribution, control, communication and monitoring allowing autonomous operation. This ensures that inspection, maintenance and repair activities can be undertaken without well shut-in, thereby avoiding loss of production. Each System-Module is normally sized for 20,000 boepd/day throughput and AlphaPRIME™ CPUs contain sufficient multiples of System-Modules to cater for the total field production throughput.

System Module Compoments

The System-Modules are lowered onto the Docking-Manifold from the installation vessel and positioned using workhorse ROVs. The System-Modules are connected to the Docking-Manifold by means of the multi-ported connector, the upper half of which is located in the base of each System-Modules. The ROV’s hydraulic supply is used to lock the wellhead type connector in place and open the isolation valves. The hydraulic supply is also used to lower the socket of the ELEx onto its plug. Simultaneously, low voltage control system connections and chemical injection stab connections are made.

From this point onward, the System-Module is entirely electrically powered and controlled.

The majority of the equipment utilised in the System-Modules are standard, industry tried and tested components, they are, however, configured in a unique way. The electric actuators, the high voltage connectors and the method of packaging are the unique features of the System-Modules.

The System-Modules can be configured in various ways and combinations. Examples of which are as follows:
