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.
