The rescue of ships in distress at sea relies mainly on vessels, which includes the approaching process and towing motion two ships. Ship can be reduced to a two-ship problem, primarily involving relative between during rescue. We established mathematical model ship based viscous fluid N-S equation, Wigley under waves was simulated two-dimensional plane. Then, according three-dimensional potent...

in this paper the problem on “magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by n ahmad et.al.[7]” has been recapitulated using jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. it is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (refer equation(2.2)). this paper re...

Nowadays, sustainable navigation is becoming a trending topic not only for merchant ships but also pleasure vessels such as motoryachts. Therefore, the adoption of hybrid-electric propulsion system and installation on-board storage devices could increase greenness megayacht. This paper analyses performance three commercial propulsive solutions, using dynamic operative profile considering influe...

We describe a variety of inter-related decisions made during daily operations at a container terminal. The ultimate goal of these decisions is to minimize the berthing time of vessels, the resources needed for handling the workload, the waiting time of customer trucks, and the congestion on the roads and at the storage blocks and docks inside the terminal; and to make the best use of the storag...

This paper is concerned with yard management in transshipment hubs, where a consignment strategy is often used to reduce reshuffling and vessel turnaround time. This strategy groups unloaded containers according to their destination vessels. In this strategy, yard template determines the assignment of the spaces (subblocks) in the yard to the vessels. This paper studies how to make a robust yar...

The Berth Allocation Problem aims at assigning and scheduling incoming vessels to berthing positions along the quay of a container terminal. This problem is a well-known optimization problem within maritime shipping. For solving it, we propose two POPMUSIC (Partial Optimization Metaheuristic Under Special Intensification Conditions) approaches that incorporate an existing mathematical programmi...
