The limited availability of berths and channels is generally the bottleneck restricting the
capacity of a seaport and thus resulting in traffic congestion. Optimizing the operations of the …

This paper considers vessel scheduling with pilotage and tugging constraints in berthing
operations with channel restrictions at seaports. To our knowledge, pilotage and tugging …

Liquefied natural gas (LNG) bunkering stations are areas for bunkering LNG-powered ships
