An Illumination Study on Floating Storage and Offloading Vessel

Abstract

There are a few floating storage offshore (FSO) facilities operating in Malaysian waters. Thisstudy was executed in one of the facilities 170 km from the East Coast of PeninsularMalaysia. The objective of this study is to investigate the lighting at the workplace at the FSOand to compare it with the recommended requirements of the Department of Safety andHealth (DOSH) Malaysia. Based on the calculated room index for each compartment, a totalof fifty-four (54) points were identified for illuminance measurement. Four representative points were selected for specific tasks/activities measurements. A total of forty-eight (48) accessibleindoor locations were measured to investigate the adequacy of the lighting (illuminance)inside the accommodation section and a few of the workshops. More than 50% of themeasured locations (i.e., twenty-eight (28) out of forty-eight (48)) were found to be recordedwith illumination below the recommended levels. The general lighting at three critical areaswas found to be low, from 17 to 109 lux. However, all three places use localized light thathas more than enough lux. At the same time, it was found that all desktop activities at thestudied locations did not manage to achieve the minimum recommended illumination levels.As for activities inside the workshops, specific tasks are supplemented with task lights. Due to this, the specific activities were found to meet the minimum illumination recommendationbased on the activities performed, even though the general lighting of each workshop wasfound to be below the recommended illumination levels.
