Embodiment Construction

[0045] In the following detailed description, a propulsion system for a marine vessel including a large two-stroke crosshead diesel engine will be described through preferred embodiments.

[0046] Figure 1 and figure 2 Shown is a large low speed two stroke crosshead inline diesel engine 10 with a 98 cm piston diameter, which is the heart of the propulsion system. These engines typically have 6 to 16 cylinders in-line. A side view of an 8 cylinder engine 10 is depicted in FIG. 1 with additional lines showing the outlines of the 9, 10, 11 and 12 cylinder modes of this engine. A scale in meters is shown below the engine 10 to indicate the absolute dimensions of these machines ranging in length from about 18 meters for the 8 cylinder model to 28 meters for the 14 cylinder model.

[0047] The engine is constructed from a base 11 with a base 11 for the crankshaft 1 ( figure 2 ) of the main bearing. The base 11 is divided into segments of suitable size according to the production...

Abstract

A propulsion system for large ocean going vessels. The system includes a large turbo charged multi-cylinder two-stroke diesel engine of the crosshead type coupled to the propeller shaft as a main prime mover and one or more substantially smaller diesel engines coupled to generators as secondary prime movers. The main engine requires electric, hydraulic and pneumatic power in order to be able to startup and operate. The main engine requires heat and small hydraulic power during short stops, and hydraulic power, pneumatic and electrical power during startup. Hydraulic power is provided by one or more high-pressure pumps or pumping stations that are driven by power takeoff from the crankshaft of the large two-stroke diesel engine, by electric motors or by auxiliary diesel engines.

Description

technical field [0001] The present invention relates to a marine propulsion system comprising a large two-stroke crosshead diesel engine. Background technique [0002] A large two-stroke diesel engine for marine propulsion is a complex machine that forms the heart of a marine power and propulsion system and includes a range of auxiliary equipment. [0003] These large two-stroke crosshead diesel engines running at low speeds are large and efficient power generating machines. The largest of these engines produces approximately 100.000 kW at 94 rpm, has a total length of 33 meters and weighs close to 3500 tons. [0004] These engines are accompanied by an auxiliary diesel engine that drives a generator, a so-called genset. The generator set provides power and heat during generator stop and during start-up. [0005] Auxiliary equipment for a two-stroke diesel engine includes, for example, a high-pressure hydraulic pump, an air pump (compressor), a lubricating oil pump, a fue...
