In a changing climate, ship speed optimization plays an important role in energy conservation and emission reduction. order to establish dual-objective model of minimizing operating costs reducing carbon emissions, fuel costs, berthing fixed cost during sailing cycles, the reduction strategies ships using MGO control areas AMP ports are taken into account. The PSO algorithm is adopted find Pare...

Space robots are one of the most promising solutions for on-orbit servicing (OOS) duties like docking, berthing, refueling, re-pairing, upgrading, transporting, rescuing, and orbital trash disposal. Numerous enabling techniques technological demonstration missions have been developed completed over past two decades. There several successful manned service missions, but unmanned not yet conducte...

To achieve environmental sustainability on ships, stakeholders should make efforts to reduce emissions. Port authorities are crucial attain this goal by introducing new policies. This study takes the of Long Beach as an example assess port-wide ship emissions and explain significance shore power policy. Additionally, considers impact disruptions, such COVID pandemic, The analysis compares data ...

In on-orbit servicing missions, a spacecraft equipped with manipulator arm grasps client satellite. Afterwards, the momentum-dumping phase follows and can be utilized for tasks. Once momentum has been dumped, desired configuration base attitude may needed initializing such as berthing. The proposed approach prioritizes maintenance of servicer spacecraft, reconfigures grasped satellite in nullsp...
