The Exhaust Gas Economizer is a device which used to generate steam by
using waste heat from the main engine exhaust gas casing and hot purification
machine. Lack of steam production when using EGE at sea voyage in MV.NYK
Vega fire A / E turbine generator not applicable, thus it is necessary to have
additional power source to fit on reefer container. To cope while the Engineer uses
two diesel A / E generators to meet the source requirements. The purpose of this
research was to look at its impact on steam production at the time of voyage in MV.
NYK Vega and to find out what can be done to improve EGE's performance on
steam production at sea passage in MV. NYK Vega.
This research uses qualitative descriptive method using data analysis
technique strengths, weaknesses, opportunities, and threats (SWOT) is systematic
identification of various factors to formulate company. Data collection is done by
interview, documentation, observation by observing at maintenance and repair time
in MV. NYK Vega.
After identified the impact of EGE on steam production at the time of voyage
in MV. NYK Vega is an inactive A / E turbine generator at sea voyage and sparks
due to soot build up in EGE. Efforts are made to improve EGE performance on
steam production during sea passage in MV. NYK Vega is analyzing where leak
may occur at EGE system, by overhauling the high pressure boiler circulating
pump, replace the mechanical seal, gasket at pump, and keep watch the leakage
area every day at sea passage or at port.
