This adaptive transformation mainly completed the new fuel consumption monitoring system, the helicopter environmental monitoring system upgrade, the replacement of the whole ship's air conditioning, the overall replacement of the main crane control room and the overall painting and renovation of the helicopter platform. At the same time, in order to carry out special inspection in advance for overseas operations, the transformation of the telescopic sliding cabin sealing strip was completed in the dock, and the installation form of the rubber strip was innovative, which was used for the first time in the industry.
