1. It should be able to work normally under the following conditions

Environmental temperature: 45 ℃

Sea water temperature: 32 ℃

Lateral inclination: 12°;  22°30 '(emergency units, inland vessels);

Longitudinal inclination: 7°30 ';  10 °(emergency units, inland vessels);

Roll: 22°30 ';

Damp air, with salt mist (excluding inland vessels), oil mist, and mold, can cause vibrations and impacts during normal operations.

2. The unit should be able to output rated power under the following working conditions:

Crew in unlimited navigation area: ambient temperature of 45 ℃, primary cooling water temperature of 32 ℃, relative humidity of 60%.

Units with limited navigation area and corresponding conditions: ambient temperature of 40 ℃, primary cooling water temperature of 25 ℃, relative

Humidity of 60%.

3. The diesel engine and generator are connected elastically or rigidly and installed on the same common base, with the center aligned

Positioning pins should be added, and the concentricity and parallelism at the half coupling should be specified in the product technical specifications. The installation and fixation of the unit should use shock absorbers and have good isolation effects. The equivalent vibration intensity during the unit bench test should not exceed 45mm/s with isolation, and not exceed 28mm/s without isolation.
