Abstract

A pile positioning semi-submersible offshore dredging engineering ship comprises a semi-submersible platform, dredging equipment, a gauge pile, a gauge pile lifting system and a ship moving system; the dredging equipment is arranged on the semi-submersible platform; the gauge pile lifting system is fixed on the semi-submersible platform; the gauge pile is arranged in the gauge pile lifting system; the ship moving system is connected with the semi-submersible system. The ship can be effectively positioned during construction, the ship can be automatically moved when not in construction, the area of a water plane is effectively reduced due to the semi-submersible platform, and wave loads are reduced, so the ship is suitable for a sea area with relatively severe wind conditions and is particularly suitable for the open sea deep water areas.

Description

technical field [0001] The invention belongs to the technical field of marine engineering and relates to open sea dredging technology, in particular to a pile positioning semi-submersible marine dredging engineering ship. Background technique [0002] In recent years, the scale of dredging and reclamation projects in water areas has become larger and larger, and the requirements for dredging equipment, especially the efficiency, cost and energy saving of equipment are getting higher and higher, and dredging companies have more and more urgent needs for large dredging equipment . With the development of the utilization of marine resources, dredging ships are rapidly developing in the direction of large-scale, high-efficiency, automation, intelligence and environmental protection. In order to occupy the dredging market, countries all over the world are committed to developing a new generation of large-scale dredgers , And on these dredgers, new materials, new technologies, ne...
