Recently, the ship Huangpu Wenchao Ship Co., Ltd. for the offshore oil engineering company to build China's first pipeline trenching power positioning engineering ship 'Offshore Oil 295' successfully completed the sea test.
The ship is a type of advanced all-electric propulsion pipeline trenching power positioning engineering ship, designed by the China Shipbuilding Industry Corporation No. 808 Institute, the classification of China Classification Society (CCS). The ship equipped with all-electric drive system, Full swing propeller, DP2 power positioning system, 100 tons of folding arm climbing compensation crane and other advanced equipment, can be equipped with self-trencher, shallow water trencher and deep water trenchers and other world's main sea trenching equipment.
In recent years, most of the domestic use of floating floating vessels to carry out the sea trenching operation, but the equipment and trencher matching poor, expensive, trenching low efficiency, in the near-platform operations and Bohai pipeline complex sea operations, And its anchoring operations have posed a greater threat to the safety of the submarine facilities. 'Offshore Oil 295' can be matched with the professional lifting piping vessel to achieve the comprehensive operation of the submarine pipeline trenching and laying to enhance the comprehensive operation of the sea laying. After the ship is delivered, it will fill the gaps in the ship's position in the sea tunnel trenching industry, and the ship can also be used for the emergency repair, expansion bending installation, submarine cable laying, clean test pressure and diving.
In the course of the sea test, the typhoon 'Kazu' was affected by the typhoon 'Kanu', and the sea condition was gradually bad.Huangpu Wenchong project team timely and flexible according to the sea conditions to adjust the pilot plan, reasonable arrangements to ensure that the navigation test completed on time Gap, the project team organized shipowners, ship inspection, design institutes and other documents to carry out the ship to clean up, clean up the test end, to lay the foundation for delivery, to achieve the maximum efficiency.
