Hanwha Ocean to cut CO2 emissions from ships with smart lighting

Hanwha Ocean Co., South Korea's third-largest shipbuilder, said on Friday it has won an approval in-principle (AIP) certificate from Korean Register (KR), a member of the International Association of Classification Societies, for its smart lighting control system that shrinks vessels' carbon footprint.

The shipbuilder plans to link the system to the Hanwha SmartShip Solution & Service (HS4), its smart ship platform that provides real-time data for vessels at sea to a control tower on land.  

The technology can automatically adjust lighting levels in each area of a vessel, detect alarms that sound when lights are out of order and record all the information.

The shipbuilding unit of Hanwha Group said the smart system can reduce carbon emissions of a 174,000-cubic-meter liquefied natural gas (LNG) carrier by up to 45% annually.

Its lighting optimization function can reduce fuel and power consumption by up to 44% and extend the lifespan of lighting by 48%, Hanwha Ocean added.

“It is meaningful that Hanwha Ocean has become the first Korean shipbuilder to secure eco-friendly technology for vessel lighting,” said a company official, adding: “We will actively develop environmentally friendly products and technologies to meet our clients’ needs."

Hanwha Ocean has ramped up advancements to the smart lighting control system since partnering with Korean ship parts manufacturer Daeyang Electric Co. and KR in February to jointly develop the technology.
