PEL-6 with Remote Monitoring: Innovative Navigation Solution at Map Ta Phut, Thailand
To improve marine navigation near the BLCP power station in Thailand, two PEL-6 Precision Sector Lights with remote monitoring were installed to replace older lead lights. This modern solution was driven by the development of a new terminal and spatial limitations at the site.
Background and Challenge
BLCP is an independent power producer located at the Map Ta Phut Industrial Estate in Rayong Province, on Thailand’s eastern seaboard. The estate houses multiple energy producers supplying power across the country. BLCP receives coal and other raw materials via a marine channel adjacent to its jetty, where ships routinely dock.
Originally, navigation to the jetty was aided by two conventional lead lights mounted on a tubular steel tower. However, in 2007, the adjacent construction of a new LNG terminal by PTT LNG Company necessitated the relocation of these lead lights. The shared use of the marine channel by both companies introduced new spatial and logistical challenges.
Available space was limited and rented from the Industrial Estate Authority of Thailand, which required a highly precise and compact navigational solution.
Solution – Compact, Precise Sector Lights with Remote Monitoring
To address these constraints, two PEL-6 Precision Sector Lights were installed:
- PEL-6-3.5D with oscillating boundary
- PEL-6-5D with oscillating boundary
These high-performance LED sector lights were chosen for their ability to deliver precise optical guidance within confined spaces. The PEL technology was the only solution capable of achieving the necessary accuracy under the given spatial limitations.
Both lanterns were integrated with solar-powered systems equipped with GPRS modems, allowing remote on/off switching. This significantly reduced energy use and operational costs, as the lights are only activated when vessels are approaching the jetty.
Outcome – Improved Navigation with Lower Operating Costs
The installation of PEL-6 sector lights and monitoring has led to enhanced navigation safety and performance at the BLCP jetty. The precision sector lights efficiently guide vessels within the restricted channel space, while remote monitoring capabilities allow for streamlined control and maintenance.
BLCP prioritized optical performance, reliability, and quality in selecting a supplier. The reputation and proven longevity of the PEL lights—known to provide over 20 years of service life—made them the ideal choice for this demanding application.
