Analysis and Evaluation of Artificial Lighting in the Passenger Spaces of a 500 Gt Ro-Ro Ferry

Abstract

Lighting is an important design criterion for ships, including the ro-ro ferry. The ship’s lighting system must meet certain standards. Therefore, the present study analysed and evaluated the artificial lighting of an Indonesian ro-ro ferry. The analysed ship in the present research was a 500 GT ro-ro ferry named KMP. Takabonerate that operated across the Selayar Islands of Indonesia. The artificial lighting systems in this ship’s three passenger spaces, which are reclining seat room, sofa seat room, and passenger open space, were evaluated and analysed. The main parameter to be investigated was the room illuminance produced by the ship’s lighting system. In order to achieve the study objective, the illuminance in those rooms was calculated using analytical formulas. The calculation results were validated using direct measurements and computer simulation. The direct measurements were conducted using a luxmeter, while computer simulations were performed using DIAlux Evo 10.0 software. With this software, the artificial lighting in the passenger spaces was also simulated and realistically visualized. The research results showed that the illuminance in the reclining seat room and the sofa seat room had met the minimum illuminance value set by the Indonesian National Standard (SNI), American Bureau of Shipping (ABS), and Indonesian Classification Bureau (BKI) standards. For the passenger open space, a re-arrangement of the lighting system was conducted to improve the light distribution so that all space illumination can meet the specified standards.
