N2  - The use of fossil fuels and pollution in the maritime industry have become large concerns in recent years. There are several vessels that are operated with multiple engines at a low to medium level of utilization to meet the redundancy requirements and to handle the fluctuating loads from heavy consumers and the environment. This increases fuel consumption, emissions, and maintenance costs. A reduction in the number of online engines will reduce the operating costs of the power plant without negatively affecting its reliability. The ESS are a reliable alternative energy source that ensures instantaneous power in the event of a power failure. By using ESS, fewer engines can run at optimal or high load levels, avoiding load shedding, or phasing back of a large drive at the onset of a heavy consumer. In traditional peakshaving, the ESS will take all when the load peaks in the whole operating range of genset to avoid changing frequency. Our paper defines peakshaving into two different category namely, long- and short-term. The long-term peak shaving occurs when the battery assists in preventing standby starts of a genset during periods of changing high load. The short-term peakshaving is the period in which battery assist gensets during a heavy consumer start and assist in avoiding load spikes on gensets running at high loads which might cause load shedding. In this paper, we analyze how the short- and long-term peakshaving function of ESS reduces fuel consumption and maintenance costs. Using simulations of typical marine operational loads, this paper discusses the benefits of long- and short-term peakshaving functions of ESS that results in improved engine health, reliability and fuel consumption.
