Zum Beispiel, fuel gas systems feature double-walled LNG pipes that can withstand pressure build-up as well as contain gas in case of a leak. ST Engineering’s LNG ships are equipped with innovative features for the safe handling and storage of LNG gas. ![]() Safety is the biggest concern among LNG ship operators. Taking CAPEX and OPEX into account, the LNG Ropax broke even with its rivals within one year, with potential savings of up to S$23.4 million over a five-year period.Įnhanced Safety Assurance with ST Engineering’s Proven Design Experience The CAPEX for the LNG variant is estimated to be 10% higher than Nova Star, however its annual fuel cost was significantly lower than the Nova Star, which runs on HFO. Studies on the Nova Star also showed that LNG fuel is significantly more effective in lowering EEDI compared to various energy solutions available in the market.Ī comparison between Nova Star and its LNG variant was done to determine the capital ( CAPEX) and operating ( OPEX) expenditure of fulfilling the environmental regulations. A comparison between ST Engineering’s Nova Star( a HFO/MDO Roll-on/Roll-off passenger (Ropax) vessel, as shown in the hero picture) and its LNG-powered variant revealed a 25% decrease in carbon emission by converting HFO/MDO engines to LNG-powered systems. The Energy Efficiency Design Index ( EEDI) measures the mass of CO 2 emitted per tonne-mile. EIN 20% reduction in CO 2 emission can be achieved by switching from Heavy Fuel Oil/ Marine Diesel Oil ( HFO/MDO) to LNG. The main and auxiliary engines of a vessel are the main contributors of CO 2 emission. This amounts to a 1% reduction every year. Sizeable reduction in Carbon ( CO 2) emissionĪll ships built 2015 and onwards are required to reduce CO 2 emission by 5% every five years. LNG adoption eliminates SO x and PM emissions and complies fully with the sulphur mandate under MARPOL Annex VI, Regulation 14. LNG adoption, jedoch, would result in more than 90% reduction in NO x emissions.Įliminates Sulphur Oxides ( SO x) and Particulate Matter (PM)ĭurch 2020, the global sulphur cap will be reduced to 0.5% m/m, nahe bei 90% reduction from 2012.

Oft kannst Du durch einen Wechsel raus aus der Grundversorgung eine Menge Geld sparen. More than 90% reduction in Nitrogen Oxides ( NO x) emissionĪll ships constructed from 2016 onwards and operating within Emission Control Areas must comply with Tier III emission standards specified under the International Convention for the Prevention of Pollution from Ships ( MARPOL). Here are six ways ST Engineering’s LNG-powered marine solutions can deliver improved fleet performance. Nel caso in cui il motore sia ad alti giri oppure al massimo, la marmitta viene messa in comunicazione con il collettore di scarico proprio da questa valvola, allo scopo di scaricare le quantità di gas in eccesso che potrebbero altrimenti danneggiare il motore.Demand for LNG vessels will soar as regulations on green and sustainable environments are increasingly implemented. Quando il motore invece gira a bassi-medi regimi, la valvola Wastegate rimane chiusa affinché l’intero volume dei gas di scarico in circolo agiscano sul girante, ossia la turbina. La ***valvola Wastegate regola il flusso dei gas generati dallo scarico*** dal momento che questi azionano il turbocompressore: infatti, soprattutto ad alti regimi, questa valvola ha lo scopo di evitare che si generi una pressione troppo elevata. La valvola Wastegate regola il flusso dei gas generati dallo scaricoįunzionamento del motore diesel (4 tempi): Gaswechsel Italian translation: ricambio del gas Social Science, Sociology, Ethics, etc.General / Conversation / Greetings / Letters.Automotive / Cars & Trucks Change Discipline ![]()
