海底管线,用水泥保护起来
这是阴极保护用的,锌块之类,这东西在墨西哥等地方用的很多。发个说明:
CP Mat combines the proven technology of a segmented concrete stabilization mattress with an integrated cathodic protection system. Placement of a CP-Mat provides the required stabilization and the added benefit of up to 30 years of cathodic protection for up to 2 miles of pipeline in each direction. Tieback to the pipeline can be made with diver or ROV using the field proven RetroClamp™ system. There is no need to remove a pipeline’s concrete weight coating. Mats are provided with patented non-shielding soft pads on the underside and can be loaded with aluminum or zinc anodes, making them suitable for all water chemistry (from seawater to river water).
