Description

Cloud-based regasification facility remote control system in connection with the ship Internet of Things {FSRU REMOTE OPERATING SYSTEM BASED CLOUD CONNECTING SHIP INTERNET OF THINGS}

Internet-related cloud-based regasification facility remote control system.

As natural gas demand increases worldwide, technologies for the production, supply and transportation of natural gas are linked to national competitiveness. In countries where natural gas is not produced, liquefied natural gas (LNG) is imported from neighboring countries by natural gas supplied through onshore pipelines or by means of transport. The liquefied natural gas transported using a transport ship is stored in a land storage in a liquefied state, and regasified and supplied according to conditions such as pressure, flow rate, and temperature according to the demand of the customer.

However, LNG storage onshore can be stably installed in areas with demand for LNG, but it is not suitable for installing LNG storage because it requires high installation and maintenance costs to install in areas with temporary or seasonal demand. Do. In addition, facilities for regasification of LNG on the ground are at risk of causing major problems when damaged by terrorism or natural disasters.

Therefore, the technology of supplying LNG that has recently been imported using a transport vessel from a transport vessel directly to the demand on land is used, or in a floating structure equipped with storage and regasification facilities for LNG, the stored LNG is regasified to land The technology that supplies directly to the customer's demand is used.

At this time, the vaporized natural gas has an appropriate gas composition, and it is necessary to supply the gas composition and gas supply flow required by the on-demand demand source to the on-demand demand destination. However, a gas metering system for measuring such gas state information is installed on a ship or floating structure together with an LNG regasification facility. Therefore, only the operator who operates the LNG regasification facility can check the gas configuration and gas flow status, and there is a problem that the information cannot be checked on land or in other locations.

Moreover, LNG regasification facilities installed on ships or floating structures can be controlled only on ships or floating structures. Therefore, when the conditions for the gas composition or gas flow condition required by the demand onshore are changed, there is a problem that it is impossible to control the LNG regasification facility to meet the demand immediately.
