Hanwha Ocean Develops Ship Lighting System Reducing Carbon Emissions by 45%

Korean Register Obtains Concept Approval

Hanwha Ocean is commercializing a smart lighting system for ships that simultaneously reduces carbon emissions and fuel consumption.

Hanwha Ocean announced on the 12th that it has obtained Approval in Principle (AIP) for the 'Smart Lighting Control System' from Korea Register (KR).

This system dynamically adjusts the lighting intensity according to different ship zones. In corridors inside the ship, motion detection sensors are used so that lights turn on only when people are passing through. In the engine room, lighting control based on time reduces brightness to 5% of the usual level outside working hours. Common areas such as dining rooms are equipped with switches that allow direct brightness adjustment.

Additionally, for the first time in the shipbuilding industry, a centralized lighting control program has been installed on the ship to enhance convenience. Through the lighting control program of the central control device in the wheelhouse, the installed lights on the ship can be controlled individually or by groups. It also allows status monitoring, fault alarm detection, and provides recording functions.

Based on an analysis of the economic efficiency of the smart lighting control system for a 174,000㎥ LNG carrier, annual carbon dioxide emissions were found to be reduced by up to 45% compared to conventional lighting. Fuel and power consumption decreased by 44%. As a result of optimizing the lighting intensity, the lifespan of the lights increased by 48%.

In February, Hanwha Ocean signed a business agreement with Daeyang Electric Co., Ltd. and KR for joint technology development of the smart lighting control system applied to ships and has been focusing on securing related technologies. Hanwha Ocean plans to integrate the smart lighting control system with its own smart ship platform, 'HS4® (Hanwha Smart-Ship Solution & Service),' to provide integrated monitoring.

Seoh Haengmyeong, Executive Director of Hanwha Ocean, said, "It is meaningful that we have secured eco-friendly technology solutions related to lighting fixtures for ships for the first time among domestic shipyards in line with the strengthening of global environmental regulations," adding, "We will actively pursue the development of eco-friendly products and technologies that can meet customer demands."
