Problems solved by technology

At present, the oil and gas transportation of domestic FLNG ships has just started. During the transportation of oil and gas resources, there will be problems such as liquid storage sloshing. Due to the high pressure in the floating oil and gas production storage and unloading device, the liquid storage sloshing will cause damage to the hull and affect the oil and gas transportation process. security
At present, the safety of the transportation process is mainly ensured by reducing the speed of oil and gas transportation, which sacrifices transportation efficiency and increases transportation costs

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with specific embodiments.

[0017] Such as figure 1 , 2 The liquid storage sloshing control method of the floating oil and gas production, storage and unloading device shown in the present invention includes the following steps:

[0018] Step 1. Calculating the first-order vibration frequency of liquid storage sloshing in the floating oil and gas production, storage and unloading device. The specific steps are: arrange acceleration sensors on the floating oil and gas production, storage and The vibration acceleration data collected during the process is analyzed to obtain the first-order vibration frequency of the storage liquid sloshing of the floating oil and gas production, storage and unloading device. The sampling time of the vibration acceleration data is usually the vibration acceleration during 1 to 2 hours of transportation at a constant speed;

[0019] Step 2. Determine the basic paramet...

Abstract

The invention discloses a stored liquid shaking control method of a floating-type oil and gas production storage and discharging device. The method comprises the following steps that the first order vibration frequency of stored liquid shaking of the floating-type oil and gas production storage and discharging device is calculated; basic parameters of a cuboid tuning liquid damper are determined;a base used for supporting the tuning liquid damper is welded to the floating-type oil and gas production storage and discharging device, and the tuning liquid damper is installed on a fixed base; whether or not the shaking reducing amplitude of the liquid surface reaches the standard is judged according to change conditions of the shaking amplitude of stored liquid after installment of the tuningliquid damper, and if not, the liquid level of the tuning liquid damper is adjusted until the shaking amplitude of the stored liquid surface in the floating-type oil and gas production storage and discharging device reaches the standard. According to the method, the shaking amplitude of the stored liquid is reduced, the safety of oil and gas resources stored in the floating-type oil and gas production storage and discharging device in the transporting process is greatly improved, and the schedule and benefit of the oil and gas resources in the transporting process are improved.

Description

technical field [0001] The invention relates to a liquid storage sloshing control method, in particular to a storage liquid sloshing control method for a floating oil and gas production, storage and unloading device. Background technique [0002] The FLNG ship integrates the liquefaction, storage and loading and unloading of offshore natural gas. It has the characteristics of low risk for the development of offshore gas fields, low mining investment costs, high safety, and easy migration. FLNG is widely used in the development of offshore oil and gas resources due to its unique advantages. At present, the oil and gas transportation of domestic FLNG ships has just started. During the transportation of oil and gas resources, there will be problems such as liquid storage sloshing. Due to the high pressure in the floating oil and gas production storage and unloading device, the liquid storage sloshing will cause damage to the hull and affect the oil and gas transportation proces...
