Description

technical field [0001] The invention relates to a floating platform for storage and transfer of drilling and production materials for development of deep-sea oil and gas fields, which has the storage and transfer functions of fuel oil, fresh water, drilling water, drill pipes, casings, bulk materials, etc. at the same time. Background technique [0002] With the continuous expansion of the scale of human development of offshore oil and gas, the main battlefield of offshore oil and gas exploration and development has shifted to the deep sea, and the development of offshore oil and gas resources requires a large , drilling water and living supplies, etc.), currently offshore oil and gas resources development drilling and production materials are generally directly supplied by ships from mainland base wharves, supply ships are limited by the berthing requirements of oil and gas field development facilities, and offshore oil and gas development materials generally use three-purpo...
