Embodiment Construction

[0216] The method of converting a steam turbine powered LNG carrier, object of the present invention, basically comprises, as can be seen in the accompanying drawings, the addition of one or more generating sets (47), together with their auxiliary components (48, 49, 50 . The mechanical connection of the output shaft assembly (19, 20, 23) of the device to emit power. This mechanical power is introduced into the gearbox (25) or the existing output shaft assembly (19, 20, 23) through a specific method, maintaining the full operation of the existing steam turbine (2, 3) propulsion equipment, having the characteristics of It is to maintain the existing steam turbine propulsion equipment, so that the converted transport ship has diesel electric or turbine electric propulsion devices, combined with the aforementioned two steam turbine propulsion and hybrid propulsion devices. The output shaft assembly is understood to be the assembly mainly defined by the intermediate bow shaft (19...

Abstract

The present invention relates to a method of converting steam turbine-powered LNG carriers, in which diesel electric propulsion comprising several dual-fuel electric power diesel, gas turbine generators or others, and several electric propulsion engines, is added, the mechanical power of which is injected in the existing gearbox or in the shaft line, keeping the existing steam turbine propulsion plant fully operative. The main advantage of the present invention is that it allows providing steam turbine-powered LNG carriers with a more economical and energy efficient shipboard power generation and propulsion plant without needing to eliminate the existing propulsion plant, therefore minimizing the conversion time, with the subsequent financial saving.

Description

technical field [0001] As the title indicates, this specification relates to a method of converting a steam turbine powered LNG carrier for transporting liquefied natural gas, characterized by the addition of diesel with several dual fuel electric diesel generators or other and several electric propulsion engines Electric propulsion, where mechanical power is introduced into an existing gearbox or shaft, keeps existing steam turbine propulsion fully operational. Background technique [0002] The transport vessel resulting from the conversion has dual propulsion: the former steam turbine propulsion, and the new diesel electric propulsion, being able to use one, the other or both as required, and all while maintaining the Shaft and gearbox in the boat. [0003] The propulsion methods used today, their advantages and disadvantages, as well as the current state of the art with respect to electric propulsion and power generation in said transport vessels, the existing conversion...
