Core Viewpoint - The launch of the "Ocean Oil 696," China's first integrated large-scale fracturing vessel, marks a significant advancement in offshore oil and gas extraction technology, addressing the challenges of low-permeability oil and gas reserves in the sea [2][8]. Group 1: Vessel Specifications and Capabilities - "Ocean Oil 696" is designed by the Shanghai Shipbuilding Research Institute under China Shipbuilding Group, featuring a length of 99.8 meters, a width of 22 meters, and a depth of 9.9 meters [2][8]. - The vessel is characterized by high integration, automation, digitization, and intelligence, achieving world-leading overall performance [2][8]. - It is equipped to meet the demands of large-scale fracturing operations across China's maritime regions, including multi-well batch fracturing and ultra-deep layer fracturing [2][8]. Group 2: Technical Innovations - The project team focused on developing an all-electric intelligent power system and integrated control for fracturing equipment to enhance operational efficiency [2][8]. - The vessel's capabilities include high displacement, high power, and large storage capacity, ensuring safe operations in offshore oil fields [2][8]. Group 3: Construction and Testing Process - The construction phase includes the completion of physical building, equipment installation, and preparation for delivery, followed by a trial run to validate performance against technical specifications [4][10]. - The trial run will test the vessel's power performance, maneuverability, equipment coordination, and operational system reliability, particularly the all-electric propulsion system and integrated control of fracturing equipment [4][10]. Group 4: Challenges and Solutions - During the testing phase, a generator failure impacted the ability to conduct electrical tests on the fracturing system. The project team adapted by shifting from serial to parallel testing to maintain progress [6][12]. - A joint working group was established to facilitate collaboration among various stakeholders, allowing for the use of shore power to conduct preliminary fracturing tests before the main generator was operational [6][12]. Group 5: Future Operations - Following the trial run, the vessel will undergo final preparations for delivery and is scheduled to be deployed for offshore low-permeability fracturing operations, contributing to efficient development of marine oil resources [6][12].
