The performance data is based on

Waste heat recovery
Necessary data for arranging waste heat
recovery plants (exhaust gas and cooling water)
are available upon request.

If there are engine driven pumps, add 0,5% for each pump. Gas feed
temperature is 20-40°C. Minimum gas feed pressure to Gas Regulating
Unit to be 4,5 barg.

Note
Due to continuous development, some data
may be change without notice.

Marine gas engine ratings are according to ISO 3046-1, at maximum 45°C
ambient air temperature and maximum 32°C sea water temperature.
Specific fuel gas consumption excluding engine driven pumps is based
on reference natural gas with Methane number above 70 and net calorific
value of 36 MJ/nm3.
