Fuel oil automatic control supply system for offshore well repair platform

Abstract

The invention relates to a fuel oil automatic control supply system for an offshore well repair platform. The system comprises an oil tank, a liquid level hydraulic monitor, a liquid level alarm, a local automatic controller, a control rotary knob, an electromagnetic valve, a control cable, a remote controller, an oil pump, a fuel oil tank, an oil supply pipeline, an oil return pipeline and a pressure alarm. By means of the local automatic controller and the remote automatic controller, when the control rotary knob is in an automatic state (namely full-automatic control oil supply), the fuel oil amount of the oil tank can be effectively monitored in real time, the fuel oil supply time and number can be precisely controlled, the continuity and the reliability of fuel oil supply of an enginein the well repair working process are guaranteed, meanwhile, unattended operation can be achieved, and a large amount of manual labor and operation is saved; the control rotary knob can be automatically switched into a manual state from an automatic state according to site requirements for manual control, and an effective supplementing means is achieved for the full-automatic control oil supplysystem; and the system is easy to operate and high in practicality.

Description

technical field [0001] The invention relates to a fuel oil automatic control supply system for an offshore well workover platform, which is applied to the fuel oil supply of the offshore well workover platform. Background technique [0002] At present, the power source of the offshore workover platform usually relies on the engine (usually a diesel engine) to provide mechanical power source and power supply, and the fuel supply system of the engine includes a fuel tank arranged above the engine, a fuel tank for replenishing the fuel tank and connecting pipelines ,Control valve. Due to the particularity of offshore workover, the engine needs to be installed on the drill floor in the workover area, and the fuel tank is installed under the drill floor in the workover area, which is usually completed by manual guarding. This method has problems such as difficulty in controlling the amount of refueling, low fuel supply efficiency due to inability to monitor in real time, need fo...
