“…The fuel saving potential of speed profile optimisation in the voyages studied was 1.1% across all studied ships, which is in line with the results of similar studies on speed profile optimisation [14,22,24]. This value is not all that significant considering that the error margins of the model and uncertainty in weather predictions may also shift the actual result.…”

“…Speed profile optimisation in relation to voyages from port A to port B with a fixed schedule were studied in [14,[20][21][22][23][24][25]. In [14], the authors developed a forward dynamic programming algorithm for solving the route and speed profile of a ship.…”

“…Choi et al proposed a speed optimisation model for ice regions, considering that ice areas can change over time [19]; they used the A * algorithm to plan an optimal navigation path. Park et al [20] proposed a two-stage weather routing model. In the first stage, the ship's speed is maintained and the A * algorithm is employed to achieve route path optimisation.…”

“…Szłapczynska and Smierzchalski (2009) introduced multi-objective approaches in weather routing, and Szlapczynski and Szlapczynska (2012) used evolutionary methods for the multi-ship trajectory planning problem. Park and Kim (2015) combined the A* algorithm with a speed scheduling phase problem in order to minimize fuel consumption and achieved reductions between 2 and 3% in their case studies. Bentin et al (2016) use the A* algorithm on a bulk carrier and optimize fuel consumption considering also wind-assisted propulsion via Flettner rotors.…”
