Description

선박의 벙커링라인 쿨링시스템{BUNKERING LINE COOLING SYSTEM OF SHIP}Ship's bunkering line cooling system {BUNKERING LINE COOLING SYSTEM OF SHIP}

본 발명은 선박의 벙커링라인 쿨링시스템에 관한 것이다.The present invention relates to a bunkering line cooling system of a ship.

LNG(Liquefied Natural Gas)와 같은 액화가스를 연료로 사용하는 선박은 다양한 벙커링 방법에 의해 액화가스를 공급받을 수 있다. 벙커링 방법으로는, 탱크로리에서 선박으로 충전하는 방식, 육상용 고정식 저장탱크에서 선박으로 충전하는 방식, 터미널에서 선박으로 충전하는 방식, 해상의 벙커링선에서 추진선으로 충전하는 방식 등이 있다.Vessels that use liquefied gas such as LNG (Liquefied Natural Gas) as fuel can receive liquefied gas through various bunkering methods. As the bunkering method, there are a method of charging from a tank lorry to a ship, a method of charging from a fixed storage tank for land to a ship, a method of charging from a terminal to a ship, and a method of charging from a bunkering ship at sea to a propulsion ship.

여기서 선박 대 선박 즉, 해상의 벙커링선과 추진선 간 벙커링하는 방법의 경우, 벙커링선으로부터 추진선으로 로딩설비에 의한 액화가스 로딩작업이 수행된다. 이때, 벙커링선의 저장탱크는 추진선의 저장탱크와 벙커링라인을 통해 연결된다. 벙커링라인은 로딩라인 및 회수라인을 포함한다. 벙커링선은 로딩라인을 통해 추진선의 저장탱크로 액화가스를 로딩시키고, 회수라인을 통해 추진선의 저장탱크로부터 증발가스를 회수하여 벙커링선의 저장탱크 내 압력을 일정 수준으로 유지시키는 데에 활용할 수 있다. 이러한 로딩라인 및 회수라인은 벙커링 작업을 수행하기 이전에 미리 쿨링된 상태여야 한다.Here, in the case of a method of bunkering between ship-to-ship, that is, between a bunkering ship and a propulsion ship on the sea, a liquefied gas loading operation is performed by a loading facility from the bunkering ship to the propulsion ship. At this time, the storage tank of the bunkering ship is connected to the storage tank of the propulsion ship through the bunkering line. The bunkering line includes a loading line and a recovery line. The bunkering ship can be utilized to maintain the pressure in the storage tank of the bunkering ship by loading liquefied gas into the storage tank of the propulsion ship through the loading line and recovering the boil-off gas from the storage tank of the propulsion ship through the recovery line. These loading lines and recovery lines must be pre-cooled before bunkering.

그러나, 벙커링선이 접안한 후, 벙커링선에 로딩라인 및 회수라인을 연결하고, 로딩라인 및 회수라인에 대한 쿨링 작업을 수행할 경우, 쿨링 작업이 완료되기까지 상당한 시간이 소요되며, 추진선에 액화가스를 공급하는 데에 차질을 빚을 수 있다.However, when the loading line and the recovery line are connected to the bunkering ship after the bunkering ship is docked, and the cooling work for the loading line and the recovery line is performed, it takes a considerable amount of time to complete the cooling work. It can interfere with the supply of liquefied gas.

In addition, after passing through the connection line 130 as in FIG. 1, the liquefied gas moves from the top of the other side of the recovery line 120 to the one side of the recovery line 120 close to the storage tank T1 of the propulsion ship, It may flow to the supply line 140.

추진선의 저장탱크(T1)에 저장된 액화가스가 바텀필링라인(111)의 제1바이패스라인(111a)을 통해 이동하는 경우에는 신속하게 로딩라인(110) 및 회수라인(120)에 대한 쿨링이 이루어질 수 있으며, 해당 액화가스는 긴 라인들을 통과하면서 자연스럽게 기화될 수 있다.When the liquefied gas stored in the storage tank T1 of the propulsion ship moves through the first bypass line 111a of the bottom filling line 111, cooling of the loading line 110 and the recovery line 120 is quickly performed. The liquefied gas may be naturally vaporized while passing through long lines.

At this time, the degree of opening of the third flow valve V13 disposed in the first bypass line 111a is controlled based on the temperature measured by the temperature measuring device 150 that measures the cooled temperature of the loading line 110. The liquefied gas stored in the storage tank T1 of the propulsion ship may flow through the first bypass line 111a, thereby cooling the loading line 110 and the recovery line 120.
