Abstract: The disclosure provides a device and a method for erecting submarine pipelines in marine engineering, including: a first bottom plate, a first clamping piece and a second clamping piece, where the first clamping piece includes a moving support and a first clamping jaw, the moving support is arranged on the first bottom plate and driven to move by a moving mechanism, the first clamping jaw is arranged on the moving support for positioning and preliminarily clamping the pipeline; the second clamping piece includes a fixed support and a second clamping jaw, the fixed support is fixed on the first bottom plate, and the second clamping claw is arranged on the fixed support for clamping the pipeline for the second time; the second clamping piece and the first clamping piece are arranged along a first direction, and the first direction is the axial direction of the pipeline.

Abstract: A real-time monitoring device for a polar nearshore marine environment is provided, including a cabin body, a main control cabin and a scraping structure, an outer wall of the cabin body is provided with collecting holes, an electric motor is arranged in the main control cabin, the electric motor provides power through a first rotating rod penetrating a side wall of the main control cabin. The scraping structure includes a power structure, a scraper and a collecting bucket, the scraper is arranged outside the cabin body and is fixedly provided with the collecting bucket. The power structure is connected to the first rotating rod and drives the scraper and the collecting bucket to rotate relative to the cabin body, the collecting bucket collects the floating objects on the outer wall and around the cabin body, and the floating objects enter the cabin body through the collecting holes.

Abstract: The present disclosure provides a transportation device and method for ocean engineering structures. The transportation device includes a transport case body and a supporting member, where the transport case body has an accommodating cavity for loading cargoes. The supporting member includes a supporting plate, a protective plate and at least one supporting rod, where the supporting plate is arranged in the accommodating cavity, and the supporting plate is driven to ascend and descend in a first direction by at least one lifting mechanism to ascend to a first position to be close to the opening or descend to a second position to be far away from the opening. The protective plate is rotationally connected to the transport case body to shield or expose the opening, at least one sliding groove is provided at the protective plate, and each sliding groove is correspondingly and slidably connected to one supporting rod.
