With a focus on industrial energy transition, particularly in the transportation sector, this study analyzes the application of hybridization as a means to optimize energy production in vessels. Data from a platform support vessel for oil were collected over 6 months. It was observed that this vessel conducts operations with a high degree of transience, which tends to increase the specific fuel consumption of thermal engines by operating outside their optimal points. A simulator was created to compare the vessel s collected operations with those of an energy generation system containing an energy storage unit—specifically, lithium-ion batteries connected to the bus powering electric propulsion motors, absorbing transient loads from the ship s demand and allowing thermal engines to operate optimally in relation to consumption. Strategies were suggested using simple averages and moving averages to coordinate engine power in hybridization, maintaining their behavior more stable and closer to operation with lower specific fuel consumption. It was noted that for operations with higher transience, particularly those involving dynamic vessel positioning, hybridization was more efficient, resulting in a consumption reduction exceeding 30 percent. Finally, a case study was conducted for the application of hybridization in a typical month of vessel operation. After applying the simulations, consumption reduction values of 45,701liters/month were obtained, representing a 22.58 percent fuel savings for the vessel. Extrapolating the operation for the system s 10-year expected lifespan, its financial viability was confirmed, with an estimated annual savings of 2,761,317.43 reais attributed to reduced consumption and maintenance costs.
