Abstract
A sea bed oil producing and processing complex has a template with three bays housing pairs of modules, viz, well, gas and oil production modules. The complex includes a separator for separating oil and gas and a pump for the produced oil, and bars having pipework to carry fluids between the pairs of modules and to despatch separated gas and oil. Saddles may carry fluids across between individual modules of a pair and the complex may have facilities for artificial lift, water injection, chemical fluid injection and for test fluids. Multiples of the three bays and pairs of modules may be within a single template and a number of modules may surround a central piping template. The complex can be services and maintained in a diverless mode using a monohull vessel and an ROV.
Claims9
A sea bed oil producing and processing complex comprising
- (i) three rectangular bays housing pairs of modules, which are
- (a) a well bay housing a well module and a well choke module,
- (b) a gas production bay housing a gas production module and a second gas module, and
- (c) an oil production bay housing an oil production module and a pump module,
- said bays being positioned side-by-side, with the longer sides of the rectangles adjacent so that the well module, gas production module and oil production module are in a line at right angles to the length of the bays and well choke module, second gas module and pump module are similarly in line at right angles to the length of the bays,
- (ii) a separator and pump for separating oil and gas and pumping separated oil,
- (iii) a piping bar connecting the well choke module, second gas module and pump module, said bar being at right angles to the length of the bays, and
- (iv) a gas piping bar parallel to the length of the gas production bay for the despatch of separated gas, and an oil piping bar parallel to the length of the oil production bay for the despatch of separated oil.
