Problems solved by technology
This jack-up platform spud shoe is welded by metal plates, which is prone to rust and corrosion. Once damaged, it will seriously affect the structure and stability of the platform; if the damage is not found before or during towage, it may cause The platform is tilted, which will result in the inability to lift in place when towed to the destination, and must return to the dock for maintenance, which will not only cause economic losses but also delay the delivery time

The invention relates to a monitoring device for damage and water inflow of spud shoes of a multifunctional self-elevating support platform in an offshore oil field. A water immersion sensor and a camera with an auxiliary light source are installed in the boot, and an audible and visual alarm connected to the water immersion sensor and the camera wire with an auxiliary light source, a wireless transmitter and its transmitting antenna are installed on the top of the leg. The control box and its solar power supply device electrically connected to the wireless transmitting device, the receiving antenna is installed outside the monitoring room, the filter amplifier and wireless receiving device connected to the receiving antenna are installed in the monitoring room, and the output end of the wireless receiving device is connected to a video switcher and a display . Through the display, the monitoring personnel can know the damage of the spud can in time, and take measures to repair it, which greatly improves the safety of the platform towed in place and the overall safety of the platform; in addition, the present invention has the advantages of energy saving, environmental protection, and easy operation.
Description
technical field [0001] The invention relates to a multifunctional self-elevating support platform spud shoe damage water inflow monitoring device for an offshore oil field. Background technique [0002] Petroleum, as the main source of world energy supply, has become an important strategic resource to promote national economic development. The technology and construction process of offshore oilfield jack-up platforms are very mature. The spud legs and spud shoes are the main components of offshore platform support. Its structure is as follows: the four corners of the platform are equipped with pile legs that can be automatically lifted to support the platform, spud shoes are welded at the bottom of the pile legs, and a monitoring room is installed on the platform. This jack-up platform spud shoe is welded by metal plates, which is prone to rust and corrosion. Once damaged, it will seriously affect the structure and stability of the platform; if the damage is not found befor...
