SEWAGE COLLECTING TANK UNIT

Sewage in a ship is divided into grey water and black water. Dumping sewage at sea while a ship is anchored or when a ship is within certain distance from land is strictly prohibited by law for environment protection.

Discharging filthy water at sea after chemical treatment is also prohibited, requiring Sewage Collecting Tank to hold it until the ship is in condition of discharging sewage at a designated place.

Sewage란 선내에서 발생하는 두 가지 종류의 오수(Grey water and Black water)를 포함하며

해양환경 보호를 위하여 정박 중이거나 육지로부터 일정거리 이내에서 운항 중 해상에 바로 투기하는 것을 법으로 금지하고 있습니다.

아울러 약품으로 처리 후 배출하는 경우에는 해상의 적당한 위치에서 배출하기 위해서는 일정한 보관 장소가 필요하며

Sewage Collecting Tank가 이 역할을 담당하게 됩니다.

The engine room of a ship includes generators, boilers and various other units. Especially Feed Water Filter Tank pulling sea water and feeding cooling water to a boiler consists of a filter separating andremoving impurities from sea water, an oil detector keeping it from sea oil inflow or a back flow of oil, and a salinometer measuring salinity of incoming sea water. Steam injector is installed inside tank to keep the temperature of the tank between 60 and 80 degrees Celsius. In addition, outside of the tank outside is kept warm. Similar volume of Pump units, such as Feed Water Pump, Circulation Pump, Economize F.W. Pump, are united all together based on required capacity.

선박의 엔진 룸에는 발전기, 보일러등을 포함한 각종 설비들이 있는데 특히 해수를 끌어다가 보일러의 냉각수를 공급하는Feed Water Filter Tank는 각종 불순물을 제거하는 필터와 Oil 오염을 막기 위한 Oil Detector, 해수의 염도를 측정하기 위한 Salinometer등이 설치 되어있으며, 섭씨 60도에서 80도 정도의 수온을 유지하기 위하여 스팀 분사기를 탱크내부에 장치하고 외부는 보온을 합니다. 이 곳 주변에 Feed Water Pump, Circulation Pump, Economize F.W. Pump등 용도에 맞는 용량의 펌프 유닛을 구성하게 됩니다.


All machineries just starting up in the Engine Room(E/R) naturally emit heat. To absorb the emitted heat, fresh water circulates surroundings of those machineries in the E/R. As the fresh water temperature goes up, sea water takes the role of cooling down its temperature. This cooling unit with pipes, valves and other accessories is called Central Fresh Water Cooler Unit. To prevent cooler from corrosion by the highly corrosive sea water, titanium plate (general thickness is 0.5mm), which has an excellent corrosion resistance feature, is normally used for Central Fresh Water Cooler. A Central Fresh Water Cooler Unit generally consists of 2 or 3 sets of cooler.

열을 발산하는 모든 기계로부터 Fresh Water가 열을 흡수하여오면 이를 해수를 통해 흡수된 열을 식히게 되는데 이러한 기능을 하는 장비가 Central F.W. Cooler입니다. 해수로 열을 식히므로 재질은 내식성이 우수한 titanium plate(보통두께 0.5mm)를 사용하며 통상 60% x 2sets로 설치하지만 용량이 클 경우에는 50% x 3sets를 설치하기도 합니다.

CENTRAL FRESH WATER COOLER UNIT

FRESH WATER JACKETCOOLING PUMP UNIT

This pump unit cools down Main Engine Jacket F.W. Preheater by drawing cooling water near main engine when the engine is operated.

Cooling water goes through F.W. Generator, Oil Detector, Deaerating Chamber, M/E Jacket Cooling Pump and finally reaches M/E Jacket F.W. Preheater. Based on Engine volume, various pumps meeting standard requirements are applied.

선박의 메인 엔진이 작동될 때 엔진 주위의 냉각수를 회수하여 Main Engine Jacket F.W. Preheater에 공급하는 펌프 유닛으로

F.W. Generator를 거친 냉각수가 Oil detector, Deaerating Chamber, Main Engine Jacket Cooling Pump를 거쳐

Main Engine Jacket F.W. Preheater에 도달하게 됩니다. 펌프의 규격은 엔진 용량에 따라 다양하게 적용됩니다.

Purifier Unit, which is composed of Main Engine F.O. Supply Unit, Generator F.O. Supply Unit and Boiler F.O. Supply Unit, is so large that it even forms itsown room in a ship. In addition, the engine of a ship is also so large that it requires large quantity of fuel. Therefore, relatively inexpensive bunker oil ismainly used for ships and Purifier Unit is installed to purify bunker oil. A great number of valves and devices are equipped as a module unit so as totransfer purified oil from Purifier to each Storage Oil Tank in the engine room, and to easily utilize and maintain those valves and devices.

Purifier Unit, Main Engine F.O. Supply Unit, Generator F.O. Supply unit, Boiler Supply Unit 등으로 구성되며, 별도의 Room을 형성할

정도로 대형입니다. 선박의 엔진은 많은 양의 연료를 사용해야 하는데 상대적으로 저가인 Bunker Oil을 주로 사용하며 Bunker Oil에 포함된

오일 이외의 불순물을 정제하기 위한 유닛으로 Purifier에서 정제된 Oil을 기관실 내 각각 필요한 Oil 저장용 탱크로 이동시키며 동시에 각 장

비의 사용 및 수리가 용이하도록 많은 수의 밸브 및 장비들이 설치됩니다.

WASTE OIL SETT/SERV TANK & M.D.O. TANK FOR INCINERATOR UNIT

Waste oil in a ship is regularly removed by an incinerator. Heating coil inside Waste oil sett/serv tank & M.D.O. tank improve oilliquidity. Hot steam goes through the heating coil keeping tanks warm while outside of the tank is also kept warm by insulation materials.

Waste Oil Sett/Serv Tank and an incinerator forms a module unit with M.D.O. tank storing marine diesel oil for an incinerator operation purpose.

선박 내에서 발생한 폐유는 선상의 소각기(Incinerator)를 이용하여 소멸시키는데 폐유의 유동성 향상을 위하여

Waste Oil Sett/Serv Tank 내부에 설치된 heating coil을 통해 hot steam을 통과시키고 동시에 Tank 외부에는 보온을 합니다.

M.D.O. tank에는 소각기 운전을 위한 중유를 저장하며 Waste Oil Sett/Serv Tank 및 주변의 소각기와 함께 모듈 유닛을 형성합니다
