Marine Propulsion Device Installed And Alignment

Marine propulsion system is the key quality control points in the process of shipbuilding, directly related to the seaworthiness of the vessel, economy and safety.At present, in view of the ship propulsion system installation and alignment, have a relatively complete technological process and key points for construction.The arrival of the but with ship's large-scale, efficient, and shipbuilding technology constantly updated, the old plan already can not adapt to new forms of shipbuilding.So in this very popular at home and abroad in this paper, the method, combining with the current in the actual work and improvement of technical means, to expound the installation of the propulsion system in shipbuilding and alignment.In order to meet the new situation to improve the quality of ship construction, shorten the ship under construction takes up port during construction period, ensure the normal order of the ship sailing in the process of the power output is stable and reliable, thus improving key mooring construction projects become the key.Propulsion system installation and alignment of the construction is always the key point of the ship's mooring phase construction project, the construction largely determine dynamic performance of the vessel, so the theory of the centerline of the propulsion system and the actual center line must try to overlap, namely the construction of the school.This requires a reasonable distribution of the host, the strong point of the axis load (weighing), content propulsion hot demand. And in the process of adjustment, although due to a variety of uncontrollable factors lead to problems in terms of ship construction precision accords with the theory, but the process is, there are rules, and that can perform certain processing (pretreatment) in advance.Based on drawings, data and actual site construction for many years of accumulated experience and statistical data as the foundation, combined with a series of ship under construction, currently mainly in the ten thousand cartons of container ship and dalian shipbuilding industry to build several VLCC combined wheel of large crude oil as an example.Describe about the propulsion installation the scheme and the rule of the school, and according to the installation in law in the school summed up the rapid construction and pretreatment, meet the construction purpose.
