Local shipbuilding firms are going green, according to industry sources.

STX Offshore and Shipbuilding, an affiliate of the nation’s mid-sized STX Group, said yesterday it has successfully developed an environmentally friendly ship capable of reducing carbon dioxide emissions and cutting fuel expenses up to half.

“With an increasing number of environmental regulations and rising fuel costs, building ships with the least amount of impact on the environment is desirable in the global shipping industry,” the STX statement said.

One regulation adopted by the International Maritime Organization will make ballast water purifiers mandatory on all ships starting in 2012.

The new STX ship has reduced the number of propeller blades from the initial four or five to three. It has also installed a wide chord tip, which decreases noise and vibrations.

To improve the efficiency of the heating system, the shipbuilder has adopted a high-tech wasted heat recovery system.

The ship is expected to reduce carbon dioxide emissions by 45 percent and increase fuel efficiency by up to 41 percent.

STX hopes its new ship will inspire other environmentally friendly business ventures.

Last year, it put together a task force to pursue research and development toward that end. It hopes to continue these efforts in the future.

“There will be more demand for eco-friendly ships in the future,” said Choi Young-dal of STX. “We will do even more research to develop a ship that emits zero carbon dioxide.”

STX is not the only one in the industry thinking this way.

Choi Kil-sun, president and CEO of Hyundai Heavy Industries and chairman of the Korea Shipbuilders’ Association, said recently that the shipbuilding industry should expect a general shift toward hybrid and eco-friendly businesses.

Hyundai Heavy, the world’s largest shipbuilder, introduced the nation’s first hybrid ship last Friday from its head office in Ulsan, South Gyeongsang.

The company received an order from the Korea Coast Guard for a 3,000-ton ship that is 112.7 meters (369.8 feet) long and 14.2 meters deep. The ship can sail an average of 28 knots per hour. One knot is 1.85 kilometers, or 1.15 miles.

In addition to having a diesel engine, the ship has a 750-kilowatt electric motor. Should the ship sail at a speed of less than 12-knots per hour, only the electric motor can be used.

“A hybrid ship reduces fuel expenses by 25 percent a year and cuts carbon dioxide emissions by some 10 tons,” said an official from Hyundai Heavy, noting the company is planning to develop its second hybrid ship next year.
