METHOD FOR CARRYING OUT OPERATIONS ON PETROLEUM AND GAS FIELDS AND DEEP-SEA PLATFORM FOR REALISING THE SAME

摘要

The present invention relates to a method for carrying out operations on petroleum and gas fields, wherein said method involves using a platform which is located underwater when in working position at a depth where it is not subject to storm waves or under the lower surface of an ice shield. The platform is made in the form of a structure which is air- and water-tight on the top and on the sides and which includes an inner volume in which all the equipment, systems and structures are provided. The platform is directed from the surface using a transport complex which moves on the water or the ice shield at the same speed as that of the current or the ice drift in the opposite direction. The platform can also be directed using a ground-based stationary complex interacting with the surface one and comprising communication means with the platform and the external world as well as a set of evacuation and other emergency and rescue means, and using equipment and devices for the remote control of the production process on the platform.
