Vessel transportation scheduling optimization based on channel–berth coordination

Ocean Engineering, 2016
Channels and berths are important resources for vessels in port operation. This study aims to improve the efficiency of vessel transportation scheduling by coordinating channels and berths. Therefore, in consideration of scheduling order, travel direction and distance of the berth, a mathematical model with minimum total waiting time as the objective ...

Measurement of marine vessel berthing parameters

Marine Structures, 2014
Abstract Load demands on ferry berthing structures are not well understood due to lack of information about berthing parameters for ferry-class vessels. Therefore, a great deal of uncertainty exists when designing these structures. Engineers are often forced to make assumptions about the magnitude of vessel impact energy as well as forces imparted to

Long wave effects on a vessel at berth

Applied Ocean Research, 2014
Abstract Disturbances to load and unload operations caused by excessive vessel movements are a recurrent problem at many ports, among which the Exterior Port of Ferrol (NW Spain). The objective of this work is to investigate whether long waves (with periods above those of swell) may play a role in these movements, and if so, to characterize their ...

NUMERICAL MODELING OF PASSING VESSEL IMPACTS ON BERTHED VESSELS AND SHORELINE

Coastal Engineering 2006, 2007
INTRODUCTION Surges generated by moving deep-draft vessels contribute to shoreline erosion, re-suspension of sediments in the surf zone, and generate significant hydrodynamic loads on berthed vessels and shoreline structures. It is desired in coastal engineering to limit vessel hydrodynamic impacts on marine resources and aquatic habitat, to improve ...

The berth allocation problem: Optimizing vessel arrival time [PDF]

Maritime Economics & Logistics, 2009
The berth scheduling problem deals with the assignment of vessels to berths in a marine terminal, with the objective to maximize the ocean carriers’ satisfaction (minimize delays) and/or minimize the terminal operator's costs. In the existing literature, two main assumptions are made regarding the status of a vessel: (a) either all vessels to be served

A methodology to assess vessel berthing and speed optimization policies

Maritime Economics & Logistics, 2010
Standard ocean shipping contracts stipulate that a chartered vessel must sail at ‘utmost despatch’, with no consideration for the availability of berths at the destination port. The berthing policies used at many ports, which admit vessels on a first-come, first-served basis, provide an additional incentive for the master to sail at full speed.

Berth allocation with service limitations on vessels

HKIE Transactions, 2016
ABSTRACTThis paper considers a vessel berth allocation problem in a river terminal with service limitations due to different water depths along the terminal. It aims at reducing the total service time for all vessels and barges, while the quay is divided into vessel berth sections and barge berth sections for berthing ships of different drafts.

Integrating fuel consumption and vessel emissions into berth allocation

ICSSSM11, 2011
This paper focuses on the berth allocation problem in the container terminal, considering fuel consumption and vessel emissions. By regarding the arrival times of vessels as decision variables and introducing the relationship between the fuel consumption rate and the sailing speed in the form of general power functions, we obtain a more elaborate model
