  • Patent number: 11058971
    Abstract: Disclosed is an oil-water separator for offshore wind farms. The separator is arranged between an oil drain pipe and an accident oil tank, and has a cylindrical structure, and includes an oil storage compartment, a water storage compartment and a partition plate between them. The disclosure can ensure that the accident oil tank is empty under normal operating conditions so that a platform weight is reduced; and an insulation and an electric heating treatments are only performed at the oil-water separator to save insulation project quantity and energy consumption for heating; and a two-stage oil-water separation is achieved in the oil-water separator to avoid mixing oil droplets into water discharged from a water outlet.

  • Patent number: 11035091
    Abstract: A transportation device for an offshore platform, including a vessel and a floating structure which are fixedly connected. The floating structure is placed on a sea surface and is configured to assist the vessel to sail. The floating structure is provided with an adjustment mechanism which is configured to adjust the floating structure to rise and fall relative to the sea surface. A rail is arranged on the vessel and is in sliding connection with the topside module, so that the topside module slides onto the vessel from land. During the transportation of the topside module, the buoyancy of the floating structure is adjusted through the adjustment mechanism, so that the floating structure provides sufficient anti-rolling moments beside the vessel, thereby reducing the vibration of the topside module caused by the winds and waves during the sailing and reducing the potential damage to the topside module.

  • Patent number: 10466117
    Abstract: Provided are a temperature sensor and an active phase-shifted grating-based temperature sensing system, relating to a fiber sensing technical field. The temperature sensor comprises a pump laser, a wavelength division multiplexer, an optical detector and an active phase-shifted fiber grating with ? phase shift. Pump light emitted by the pump laser enters the active phase-shifted fiber grating through the wavelength division multiplexer. The active phase-shifted fiber grating absorbs the pump light and emits laser light, which travels back through the wavelength division multiplexer and enters the optical detector. The optical detector measures output power of the active phase-shifted fiber grating, to analyze the power to obtain ambient temperature of the active phase-shifted fiber grating.
