Description

Test device for safety split coupler for LNG bunkering

The present invention relates to a test device for a safety separation coupler for LNG bunkering for performing various tests of the safety separation coupler for LNG bunkering.

Due to strengthened international ship emission regulations in preparation for environmental protection against global warming and climate change, countries around the world are focusing on developing eco-friendly, low-carbon fuel-enabled ships. In addition, due to global climate change and increased air pollution, regulations on pollutants emitted from ships from the International Maritime Organization (IMO), the European Union and the United States will be tightened. In order to reduce greenhouse gas emissions from ships, the International Maritime Organization proposed to reduce emissions by 20% by 2020 and 50% by 2050 based on ship emissions in 2005.

In this regard, the most promising alternative is LNG (Liquefied Natural Gas) being considered as a propulsion fuel for ships instead of diesel fuel with large emissions of pollutants. LNG is the liquefaction of natural gas in the gaseous state, and the liquefied natural gas is reduced to about one sixth of the volume than in the gaseous state, so LNG is most efficient for large distance transport.

Such vessels are divided into vessels using LNG as fuel (hereinafter referred to as 'LNG propulsion vessel') and vessels that receive and store LNG and refuel to other vessels (hereinafter referred to as 'LNG bunkering vessel'). A vessel that transports LNG from an LNG production base to store LNG and supplies it to a fueling facility (hereinafter referred to as 'LNG Bunkering Terminal') that supplies oil to LNG propulsion vessels or LNG bunkering vessels (hereinafter referred to as 'LNG transportation'). Ships').

LNG is a clean sulfur-free fuel, and there is no fuel processing facility, so even if emission regulations are applied, there is no price increase. Domestic shipbuilders also expect LNG propulsion ships to be new sources of revenue in the coming years. In addition to propulsion ships and LNG bunkering ships, the company is rushing to develop technologies related to floating LNG bunkering terminals.

In the global market, LNG-propelled ships have been distributed since 2000, mainly in Norway. As the LNG propulsion vessels increase, the demand for LNG bunkering terminals also increases.

LNG bunkering terminal can be divided into fixed LNG bunkering terminal and floating floating LNG bunkering terminal at sea.In case of fixed LNG bunkering terminal on land, the construction cost is much higher than floating LNG bunkering terminal at sea. This is long and low in stability.

Therefore, floating LNG bunkering terminals on the sea are being evaluated as an alternative to provide safe and economical bunkering environment to meet current or future LNG fuel demand.

On the other hand, when LNG propulsion vessels refuel LNG in LNG bunkering vessels, the storage tanks of LNG propulsion vessels and the storage tanks of LNG bunkering vessels are the safety separation couplers for LNG bunkering and LNG bunkering vessels connected to the storage tanks of LNG propulsion vessels.
