Abstract

The invention provides a vertical type pile support device used for processing seabed pipeline suspended span, and the vertical type pile support device is suitable for a seabed pipeline suspended span processing condition while a pipeline maximum diameter ranges from 280 mm to 500 mm, water depth is smaller than or equal to 60 m, and pipeline suspended span height is lower than or equal to 2 m. The vertical type pile support deice comprises a head hydraulic system, a supporting rod, a telescopic arm hydraulic cylinder, a piling mechanism, a rotary mechanism drive motor, a grabbing mechanism,a grabbing drive cylinder, a positioning rod, a lifting-pulling cylinder, an oil conveying pipeline, a limiting block and the like. The vertical type pile support device is simple and convenient in mounting construction, is short in construction period, can be suitable for various complex seabed geographical environments, does not need manual underwater operation, and has the increasingly emergingadvantage.

Description

technical field [0001] The invention relates to a vertical pile support device for handling the suspended span of a submarine pipeline, which belongs to the technical field of marine equipment. Background technique [0002] Submarine pipeline is an important part of offshore oil field production system, known as the lifeline of offshore oil and gas field development, and is an efficient, economical and reliable way of oil and gas transportation. Maintaining the safety of submarine pipelines is an important part of ensuring safe production and protecting the marine environment, so protecting the safety of submarine pipelines is particularly important. Compared with land, the seabed environment is relatively harsh. The seawater scours the seabed, the unevenness of the seabed topography, and the residual stress of the pipeline will cause the oil pipeline to overhang. The emergence of the overhanging phenomenon of the submarine pipeline will change the force of the oil pipeline...
