Abstract This paper provides a study on the procedure of tugboat handling for berthing and unberthing container ships in Port Surabaya Container Terminal. The elements assistance consisted time series percentage tugboats’ power, direction tug’s force, duration. developed manoeuvring simulation program using mathematical group (MMG) model to determine achieve intended trajectory properly. consid...

There are many restrictions on shipping, which reduce or prohibit the use of diesel generators for feeding energy demand electric ships, especially in ports. Therefore, shore power system (SPS) together with renewable energies and storage systems (ESSs) can lead to environmental benefits while ships berthing In this study, shipboard hybrid (HPS) is proposed, including generators, solar photovol...

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...

This paper provides an estimation of exhaust emissions released by passenger ferries at the port-level. The methodology is based on the “full bottom-up” approach and starts by evaluating the fuel consumed by marine diesel engines on the basis of its individual port-activities (manoeuvring, berthing and hoteling). Specific air emissions are estimated as regards to the different propulsion source...

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 ...
