A technical trial aimed at recycling boil-off gas(BOG) generated during the construction of LNG-powered ships took place at HD Hyundai Heavy Industries ‘ shipyard in Ulsan, South Korea.
The first demonstration of boil-off gas recycling
This project involved HD Korea Shipbuilding & Marine Engineering, Dongwha Newtech, Korean Register(KR) and a Liberian flagged company. The initiative addresses the restrictions imposed by international ports, which require the use of alternative shore power(AMP) systems for ships at anchor.
[post_relacionado]When the LNG stored in the tanks evaporates due to the increase in internal pressure, it generates a gas that should mainly be burned or released into the atmosphere. With this technology, it is captured and converted into an energy source for urban use. This process is a viable alternative to forced flaring, which is facing increasing regulatory restrictions.
The tests carried out showed that the evaporated gas, which exceeds 50 tons per vessel during construction, can be channeled and treated thanks to specialized compressors developed by Dongwha Newtech. For this purpose, KR supervised the design, testing and validation stages of the entire process.
The heads of the companies involved emphasized the strategic value of this innovation. From HD Hyundai highlighted that this is the world’s first application of BOG recycling during shipbuilding. The technology minimizes greenhouse gas emissions and anticipates compliance with future international regulations.
KR reaffirmed its commitment to the certification of technologies that promote maritime efficiency and sustainability. The demonstration shows progress towards the integral use of resources in shipbuilding, with direct benefits for the port environment.
The use of BOG as a recycled energy resource could be consolidated as a standard, especially when the use of AMP becomes mandatory on a global scale.
