Abstract
Ovaj diplomski rad analizira i uspoređuje energetsku učinkovitost pogonskih sustava na LNG brodovima. Analizirani sustavi pogona su: parnotrubinsko postrojenje, postrojenje s dvotaktnim sporookretnim motorima i sustavom za ponovno ukapljivanje plina, elektropropulzija s Wärtsilä generatorima na dvojno gorivo, elektropropulzija s MAN generatorima na dvojno gorivo, elektropropulzija Wärtsilä generatorima na dvojno gorivo i azipod propulzijom, postrojenje s dvotaktnim ME-GI motorima na dvojno gorivo – visokotlačni plin i postrojenje s dvotaktnim X-DF motorima na dvojno gorivo – niskotlačni plin. Za svaki od ovih pogona izračunata je termička energetska učinkovitost te proračunski indeks energetske učinkovitosti (EEDI – Energy Efficiency Design Index), odnosno indeks energetske učinkovitosti postojećih brodova (EEXI – Energy Efficiency Existing ships Index). Proučen je i novi ME-GA motor tvrtke MAN i dane su osnovne značajke motora na amonijak koji bi mogao biti budući odabir pogona za LNG brodove.
Abstract (english)
This master's thesis analyzes and compares the energy efficiency of propulsion systems on LNG ships. The analyzed propulsion systems include: steam turbine plant, two-stroke slow-speed engine plant with gas reliquefaction system, electric propulsion with Wärtsilä dual-fuel generators, electric propulsion with MAN dual-fuel generators, electric propulsion with Wärtsilä dual-fuel generators and Azipod propulsion, plant with two-stroke dual-fuel ME-GI engines with high pressure gas injection and plant with two-stroke dual-fuel X-DF engines with low-pressure gas admission. Thermal energy efficiency, along with energy efficiency indexes – EEDI and EEXI has been calculated for each of these propulsion systems. Additionally, the thesis examines the new ME-GA engine by MAN and provides basic features of an ammonia-powered engine, which could be a potential future propulsion choice for LNG ships.
