TOOL FOR ORIENTATION AND UPGRADING OF UNDERWATER OIL APPLIANCE AND METHOD FOR ORIENTATION OF APPARATUS

摘要

A tool for undersea oil recovery operations having a framework to carry instruments to the sea bottom to determine the angle of inclination of a ring girder secured to a monopile driven into the sea bottom. The same tool, with minor modifications, is used to transport a wedge-shaped leveling wafer to the bottom after the wafer has been fabricated to correct the previously determined inclinations.
