r noise levels ) Space integration, small footprint The present paper attempts to put the transmission mechanism (the gear box) into the picture. The gear box is an essential part of the propeller shaft line. It has as primary function the reduction of the rotational speed of the reciprocating engine to the level required for optimal propeller efficiency. However, it is more nd more functionality enabler: - It allows power take - off and take - in concepts by connecting electrical machinery to the shaft lines - It allows various layouts (relative position of engine and propeller shafting) - It is tailored to the available space envelope and the engine layout - It can allow integrated systems with the adjacent products like the CP propeller Figure 1 shows modern shaft line with high technology medium speed engine, an advanced propeller with energy saving devices and electrical machinery having the need to be connected and operate together. The gear box fulfils this need. We attempt to present in this paper that the gear box is the enabler for functionality and high performance. Figure 1. Propeller Sha ft Line with integrated systems The proper selection and integration of machinery room solutions is the first part of the long journey to smart marine solutions that we are aiming at. 2. (Machin Room ) Configurational Arrangements Gear boxes are designed for single engine to propeller power transmission or as alternative layouts with .. two main engines powering single propeller. In parallel, they enable power supply and delivery to the auxil iary system through the connected PTO/ PTI machinery . reference configuration of twin CP propeller system is presented at the upper machinery layout of Figure 2. Each gear box for this specific vessel application - is connected to two reciprocating en gines of 3MW each and power take - off generator of 2.6MW (r
