This report summarizes engine data for a CEAS 7G50ME-C9.5 HL marine engine. It provides specifications for the engine including its nominal maximum continuous rating of 12,040 kW at 100 rpm. The report lists fuel consumption values at different ratings and operating conditions. It also includes pump capacities and flow rates for systems like cooling water, lubricating oil, and seawater. The report notes this engine data should only be used for existing orders and that the latest engine catalog must be consulted for new projects.

CEAS Engine Data report

7G50ME-C9.5 HL
Project name: Практична Робота №2
Report made by: Греков Ярослав
DISCLAIMER: This engine has been replaced by a newer and more efficient engine. Data from
replaced engines should only be used for comparison and processing existing or repeat orders. For
new projects, the latest version of the engine catalogue must be used.

The Light Running Margin (LRM) shown is 5%. Recommended value is 4-7%, for special cases up to 10%. The LRM should be
evaluated for each ship project depending on for example: In-service increase of vessel resistance, ship manoeuvring requirements,
additional engine load due to power take-out (PTO) and possible requirements related to a barred speed range (short passing time).

All flows are stated as minimum required flows.
The heat capacity of the central cooler (including 5% safety margin) is calculated as the sum of the 100% SMCR heat dissipation from
all coolers in the worst case of each of the engine operational modes (fuel type, emission mode and ambient condition).
The heat capacity of the jacket water cooler and lubricating oil cooler (including 10% safety margin) is based on the highest heat
dissipation of each of the engine operational modes (fuel type, emission mode and tropical condition).
Pertaining cooling water flow diagram, temperatures, viscosities and pressures for pumps and coolers, see “Engine Project Guide”.

A) Sound pressure levels from exhaust gas system (2x10-5 Pa).


The expected sound pressure level at 1 metre from the edge of the exhaust gas pipe opening at an angle of 30 degrees to the direction
of the gas flow and valid for a normal exhaust gas system - but without a boiler and silencer.

B) Airborne sound pressure levels - with standard noise reduction (NR) countermeasures (2x10-5 Pa).
Expected mean sound pressure octave spectrum levels, i.e. the average spatial noise values at a distance of 1 metre from the engine.
Prescribed measuring surface area is 321.2 m².

C) Air-borne sound pressure levels - with additional noise reduction (NR) countermeasures (2x10-5 Pa).
Expected mean sound pressure octave spectrum levels, i.e. the average spatial noise values at a distance of 1 metre from the engine.
Prescribed measuring surface area is 321.2 m².

Additional noise reduction countermeasures, e.g.:


Extra good turbocharger air intake silencer(s)
External sound insulation of scavenge air receiver
External sound insulation of scavenge air cooler(s).

Supplementary reduction of 0.0 dB is needed.

Other additional noise reduction countermeasures are also available. The noise figures given are in accordance with the CIMAC
recommendations for measurements of the overall noise for reciprocating engines. The average levels will, depending on the actual
engine room configuration, be 1-5 dB higher when the engine is installed in the engine room.

D) Structure borne vibration levels (5x10-8 Pa).


Expected mean velocity octave spectrum levels at the engine base plate as installed on board the ship. Based on an average engine
foundation of a ship, and may only be used as a rough estimate as the velocity levels will depend on the actual foundation used. If the
vibration velocity levels are referred to 10-9 m/s instead of 5x10-8 m/s, the calculated dB figures will be 34.0 dB higher than above stated.
