Ferry demand fluctuates unpredictably across different seasons and holidays, posing significant scheduling challenges for operators and resulting in high operating costs and increased carbon emissions. To adapt to market demand variations, ferry operators often supplement their own fleets with leased vessels. Therefore, this paper explores sustainable leasing strategies between ferry leasing companies and operators under uncertain demand conditions, aiming to maximize ferry utilization efficiency. First, this paper develops leasing models under four contract types: wholesale pricing, unilateral options (call and put), and bidirectional options (a classic game-theoretic approach for optimizing decisions under demand fluctuations). Subsequently, it determines the optimal number of leased ferries for each strategy. Then, this paper conducts a comparative analysis of the four contracts, supplemented by sensitivity analysis. Finally, it examines the scenario where an operator purchases ferries instead of leasing them. A case study of a high-speed passenger ferry company in Zhuhai demonstrates that option contracts can mitigate demand uncertainty, thereby improving fleet utilization. The bidirectional option proves more flexible than the unilateral option. However, leasing is not always preferable to purchasing. The findings provide sustainable insights for ferry operators in designing leasing strategies, ultimately reducing operating costs and carbon emissions.

Vessel traffic management systems can be employed for environmental management where vessel activity may be of concern. One such location is in San Francisco Bay where a variety of vessel types transit a highly developed urban estuary. We analyzed vessel presence and speed across space and time using vessel data from the Marine Monitor, a vessel tracking system that integrates data from the Automatic Identification System and a marine-radar sensor linked to a high-definition camera. In doing so, we provide data that can inform collision risk to cetaceans who show an increased presence in the Bay and evaluation of the value in incorporating data from multiple sources when observing vessel traffic. We found that ferries traveled the greatest distance of any vessel type. Ferries and other commercial vessels (e.g., cargo and tanker ships and tug boats) traveled consistently in distinct paths while recreational traffic (e.g., motorized recreational craft and sailing vessels) was more dispersed. Large shipping vessels often traveled at speeds greater than 10 kn when transiting the study area, and ferries traveled at speeds greater than 30 kn. We found that distance traveled and speed varied by season for tugs, motorized recreational and sailing vessels. Distance traveled varied across day and night for cargo ships, tugs, and ferries while speed varied between day and night only for ferries. Between weekdays and weekends, distance traveled varied for cargo ships, ferries, and sailing vessels, while speed varied for ferries, motorized recreational craft, and sailing vessels. Radar-detected vessel traffic accounted for 33.9% of the total track distance observed, highlighting the need to include data from multiple vessel tracking systems to fully assess and manage vessel traffic in a densely populated urban estuary.

Ferry emissions are over-proportional with respect to the number of these ships. Half of the European ferry emissions stem from the Mediterranean, this largely reflecting a greater number of ships operating in this sea. Which factors affects ferry carbon intensity and energy efficiency? New insights and perspective from a study realized by the CMCC Foundation in the framework of GUTTA project activities.

Scandinavia is the first region in the world to rely increasingly on battery-powered and thus environmentally-friendly technologies in the shipbuilding industry. After "Ampere", the world's first electrical ferry in Norway, Siemens has received a follow-up order of the Finnish shipping company FinFerries. Ampere was put into operation in Norway in May 2015, and has traveled a distance equivalent to more than 1.5 times around the equator. With the change from diesel propulsion to battery, Norwegian ship owner Norled has reduced the cost of fuel by 60 percent. For FinFerries, SIEMENS has now tailor-made a suitable technical solution for Finland's first emission-free ferry. This follow-up order confirms SIEMENS' pioneer position delivering green solutions in the shipbuilding industry.
