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.

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.

The present invention relates to an offshore non-driven-in large-diameter monopile foundation structure and a construction method. An object of the invention is to provide an offshore non-driven-in large-diameter monopile foundation structure with simple structure, convenient construction and clear mechanic behavior, and a construction method. The technical solution adopted by the invention is as follows: an offshore non-driven-in large-diameter monopile foundation structure suitable for rock foundations is characterized in that a drilling hole is drilled in a rock foundation, a large-diameter monopile is implanted into the drilling hole, the bottom of the large-diameter monopile is sealed by underwater bottom-sealing concrete, and the gap between the outer wall of the large-diameter monopile and the hole wall of the drilling hole is filled with a grouting material goofed by a grouting system that is preset inside the large-diameter monopile. The invention is applied to offshore wind power and other industries.

The present invention provides a method for tackling the repelling of hammering during pipe pile driving. The technical scheme of the present invention includes: when repelling of hammering occurs in the process of piling through a sand layer, drill holes downwardly around and/or inside the pipe pile, and jet high-pressure water to the sand layer below to cut and disturb the sand layer.

The invention relates to a method to test friction resistance at inner and outer sidewalls of pipe pile through in-situ test. The method comprises embedding a strain sensor at inner or outer sidewalls of pipe pile to measure strain variation generating on pipe pile body under the action of load; carrying out static load test with the soil plug remaining in the pipe pile to obtain the strain variation &#x3b5;of the pipe pile body at the isoil layer; taking out the soil plug remaining in the pipe pile and carrying out static load test to obtain the strain variation &#x3b5;of the pipe pile body at the isoil layer; and obtaining the friction respectively at the outer and inner sidewalls of the pipe pile at the isoil layer according to the measured strain variation, &#x3b5;and &#x3b5;.
