Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] The bucket foundation of the self-installing offshore mobile platform with an oil storage tank of the present invention is composed of an oil storage tank 2 , an anchor barrel 1 , a column 4 and a ventilation pipeline 3 . There is an airtight oil storage tank 2 on the upper part of the barrel-shaped foundation, which can be divided into multiple sub-compartments through the sub-bulk walls 13, 14, 15, 16 to meet the strength requirements of the structure. Its function is to provide self-floating capability for barrel-type foundation towing under no-load conditions; it can be used as a ballast tank during the installation phase; during the platform production phase, it can realize the oil storage function by filling the tank with oil, saving round-trip transportation costs. Oil inlet and outlet holes 11,12 are arranged on the top plate of...

Abstract

The invention relates to a self-installed barrel-type foundation with an oil storage tank, which includes an oil storage tank, an anchor barrel, a column, and a ventilation pipeline, and is characterized in that an oil storage tank is fixed on the upper part of the anchor barrel, The oil tank is composed of a top plate, a double bottom plate and a double shell. On the top plate of the oil storage tank, there are oil inlet and outlet holes. The ventilation pipeline extends through the double bottom plate of the oil storage tank to the inside the anchor. The bucket foundation provided by the invention has both oil storage and self-installation functions, and has high structural reliability.

Description

technical field [0001] The invention relates to a bucket foundation of an offshore mobile platform in the field of ocean engineering, which is especially suitable for the development of marginal oil fields. Background technique [0002] The existing light-duty offshore mobile platforms are basically not equipped with oil storage devices. After oil production on the platform, tankers need to shuttle frequently between the oil field and the land to realize the transportation of crude oil, resulting in waste of manpower and material resources, and increasing the operating cost of oil field development. It greatly reduces the profitability of marginal oilfields and is not conducive to the development of isolated small oilfields. At the same time, in the event of bad weather or other external force majeure, the oil storage device on the ocean surface is prone to accidents, causing oil leakage and causing serious pollution to the surrounding environment. In addition, under normal...
