Method for carrying out operations on petroleum and gas fields and deep-sea platform for realizing the same

摘要

A method for carrying out operations on petroleum and gas fields is provided. The 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 field. The platform is made in the form of a structure which is water-tight 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 surface complex which moves on the water or the ice field at the same speed as that of the current or the ice drift in the opposite direction.
