“…In cases where the generated sail force is sufficient to move the vessel at the desired speed (100% wind generated thrust), there are various options regarding the operation of the propeller such as windmilling, feathering or harvesting (Gypa, 2023). For the optimization problem, harvesting the energy of the rotating propeller is herein not examined and the added resistance from the windmilling/feathering propeller is not taken into account.…”

“…Seasonal changes in weather can also be taken into consideration but for the examined case study the weather information is herein considered constant. It should be noted that the possible fitting of WAPS goes hand in hand with weather routing optimization, thus the examined conventional route (not optimized for prevailing winds) significantly underestimates the potential savings (Werner et al 2023).…”

International regulations as well as strong market demand for zero-emission transport call for a radical change in the shipping industry. One very promising zero-emission propulsion system for shipping is wind propulsion. In this context, the EU-funded Orcelle Wind project (https://cordis.europa.eu/project/id/101096673) aims at using wind as the main source of ship propulsion and to demonstrate the effectiveness and viability of Wind Assisted Propulsion Systems (WAPS) by a retrofitting and new building demonstrator. In this paper, we explore the effect of wing sails on the concept design of a VLCC tanker in the frame of a newly parametric ship design optimization procedure.

To achieve the goal of a 50% reduction of CO2 emission in the maritime industry by 2050, different systems and solutions were proposed by researchers. Rigid wind sails, rotor sails, suction wings, and kites were developed to contribute to cleaner and environment-friendly transportation by reducing total fuel and energy consumption. In the present study, a ship dynamics model of KVLCC2 consisting of hull, rudder, propeller, and sailing system was built considering the effects of wind and wave. Firstly, the amount of energy consumption reduction of both systems was examined under different wind directions and wind speeds. It was found that a single sailing system can reduce total energy consumption by up to 10%. Then, the effects of the ship speed, the position of the sailing system, and the number of sails on the reduction of energy consumption were examined. It was found that the amount of overall energy reduction reaches around 23% and 16% when the number of sails was increased to 10 rigid wind sails and 10 rotor sails, respectively. The effects of waves were also investigated, and it was revealed that wave forces decrease the percent energy reduction more when environmental conditions become more severe, starting from the Beaufort scale of 7.
