Selecting a marine generator set requires comprehensive consideration of the ship type, navigation environment, and power demand. The core points can be summarized into the following five aspects:

First, calculate the ship’s total electrical load (including navigation equipment, communication systems, domestic electricity, refrigeration equipment, etc.). On this basis, reserve 15%-20% redundant power to avoid shutdown caused by load overload.At the same time, distinguish the power ratio between the main generator and the standby generator to ensure that the standby unit can cover the core power demand when a single unit fails.

Prioritize models with waterproof, anti-salt spray, and moisture-resistant performance. The machine body should be made of corrosion-resistant materials (such as 316 stainless steel) or treated with special coatings to prevent seawater and high-humidity environments from eroding internal components.In addition, it is necessary to consider the jolting and tilting conditions during the ship’s navigation, and select units with anti-vibration structural design to ensure stable operation.

The selected generator must comply with the International Maritime Organization (IMO) standards and the maritime regulations of the region where the ship is registered (such as the China Classification Society (CCS) certification).It should be equipped with a complete safety protection system, including overload protection, short-circuit protection, high-temperature alarm, low oil pressure shutdown and other functions, to avoid safety hazards such as fire and electric leakage caused by equipment failure.At the same time, it must be compatible with the ship’s fire protection requirements and form a linkage with the on-board fire-fighting system.

Choose the generator fuel type that matches the ship’s power type (such as diesel power, gas power). Prioritize models with low fuel consumption and high thermal efficiency to reduce fuel costs during long-term navigation.For ocean-going ships, it is also necessary to consider the compatibility between the generator and the ship’s fuel reserve to ensure that there is no need for frequent fuel replenishment during the endurance cycle.

Combine the layout of the ship’s engine room to select units with suitable size and weight, and reserve sufficient maintenance space.Prioritize brands with highly versatile components and a wide-ranging after-sales service network, which facilitates obtaining maintenance support at different ports and reduces navigation delays caused by equipment failures.
