An oil-electric hybrid three-body high-speed ship and its working method

Abstract

The invention discloses a fuel-electric hybrid triple-hulled high-speed vessel and a working method thereof, and belongs to the technical field of designing of a high-performance vessel. The high-speed vessel comprises a main hull, two side hulls, a main power device and two auxiliary power devices, wherein the main hull is located in the middle of the two side hulls; and the side hulls are fixedly connected with the main hull through connecting parts. Through adjustment of the relative position of the side hulls and the main hull, the vessel can obtain favorable wave-making interaction, so that the resistance performance of the vessel is good when the vessel sails at a high speed; besides, due to the existence of the two side hulls, the deck of the vessel is spacious in area, cabins, equipment and the like can be easily arranged, the stability and the wave resistance are good, and the whole vessel is high in invisibility and reliability; through effective cooperation of a water jet propeller and a screw propeller, the engine and the electric motor can work in a high-efficiency area all the time; the navigation speed range is greatly enlarged; the vessel has the capability of working under multiple working conditions; and the maneuverability, the fuel economy performance and the emission performance of the vessel are improved.

Description

technical field [0001] The invention relates to an oil-electric hybrid three-body high-speed ship and a working method thereof, belonging to the technical field of high-performance ship design. Background technique [0002] In recent years, special high-performance ship types have been widely studied in various fields such as military affairs and yachts. Among them, the trimaran has received extensive attention from various ship research institutions and enterprises at home and abroad due to its good stability, excellent seakeeping performance, small wave-making resistance, and wide deck surface and equipment space. And research and development investment, the application prospect is quite broad. However, although the trimaran has good characteristics in terms of stability, seakeeping and resistance performance, there are also some problems associated with its ship type itself. In terms of performance, it has obvious shortcomings compared with ordinary monohull ships. In ...

AI Technical Summary

Problems solved by technology

The hybrid propulsion systems launched by Wärtsilä, MAN, Siemens, ABB, and 711 Research Institute at home and abroad have made some progress in reducing fuel consumption and pollution during the operation of ship main engines, realizing energy saving and emission reduction, and reducing operating costs. , but most of the research and design of each system are aimed at large ocean-going ships, and not many are actually applied to small and medium-sized trimarans

[0004] In a nutshell, most of the existing trimarans are driven by a single electric or fuel oil, and there are problems such as poor sailing performance, low manoeuvrability, low economy and environmental protection, poor safety and reliability, or cannot meet the requirements of a wide range of speeds. , the needs of multi-working conditions, etc.
