Embodiment Construction

[0032] Reference is made to the accompanying drawings which show a pipeline laying and embedding plant on the seabed, indicated as a whole by 10 .

[0033] The equipment group 10 for pipeline laying and embedding comprises: excavating means 11, for example like a trencher equipped with cutting means 16 of the seabed 20, such as milling cutters, toothed wheels and / or diamond grinding discs; and Sediment suction and removal means 13, such as drainage pumps and / or suction pumps, these drainage pumps and / or suction pumps suck the excavated debris and discharge it at the side of the trench, thereby Ribs and spurs are formed on the edges of the grooves created at 11 .

[0034] During or after the laying of the pipeline 15, in order to realize the excavation of the seabed 20, the excavating device 11 is equipped with: hooking means for hooking the pipeline 15; and / or rubberized rollers.

[0035] In this way, it is possible both to maintain the relative position between the pipe 15 ...

Abstract

The present invention relates to a group and a method for laying and burying pipelines at the seafloor, wherein the laying and burying group according to the present invention comprises a digging device (11) provided with at least means for cutting the seafloor (20) and with means for hooking onto a pipeline (15) and for sliding over the same, and is characterized in that it comprises at least one float device (14) constrainable to the pipeline (15) for supporting it (15) in span, connected to the back of said digging device (11) with respect to the direction of the movement thereof (11).

Description

technical field [0001] The present invention relates to a group of equipment and a method for laying and burying pipelines on the seabed. Background technique [0002] When laying pipelines on the ocean floor it is also desirable to bury them in order to protect them from specific local factors such as fishing, navigation, ocean currents, wave motion, natural events, etc. [0003] Based on these factors and according to the morphology and bathymetry of the seabed, in addition to determining the necessity of burying partial sections or the entire length of the pipeline, the characteristics of the cavity are also established, namely the excavation depth, the substance and level of the covering. [0004] In recent years, in line with the economic aspects involved in the operation of subsea buried pipelines, such operations have become standard in the sub-shore sector, also due to the imposition of regulations. [0005] Specifically, there are three methods used to lay and bury...
