Berth Planning by Evaluation of Congestion and Cost

Journal of the Waterways and Harbors Division, 1967
Studies of observed patterns of ship arrivals in general cargo ports for which all berths are operated by port authorities indicate satisfactory agreement with Poisson's distribution function. Analytical interrelations between berth occupancy, congestion, fixed costs of idle port facilities, and cost of waiting ships have been developed, and presented ...

Motion Planning Using Reinforcement Learning Method for Underactuated Ship Berthing

2020 IEEE 16th International Conference on Control & Automation (ICCA), 2020
This paper proposes a novel motion planning method for underactuated ship berthing using reinforcement learning (RL) technique. The berthing motion planning problem is formulated as a Markov Decision Process, where a specified reward function is designed for the accurate berthing task.

Optimal Energy Trajectory Planning and Control for Automatic Ship Berthing

2020 39th Chinese Control Conference (CCC), 2020
This paper proposes an optimization method for the ship's optimal berth trajectory based on the ship dynamics. By introducing a mathematical dynamic model which helps to describe the nonlinear dynamic system of a ship, this paper attempts to solve the problem of optimal trajectory planning for ship berthing.

Berth Allocation Planning Optimization in Container Terminals

2007
We study the problem of allocating berth space for vessels in container terminals, which is referred to as the berth allocation planning problem. We solve the static berth allocation planning problem as a rectangle packing problem with release time constraints, using a local search algorithm that employs the concept of sequence pair to define the ...

Planning for a New Berth in New York Harbor

Ports 2010, 2010
It has been over twenty-five years since the last container terminal was developed in the harbor. The Port Authority of New York & New Jersey (PANYNJ) purchased 124 acres of the old Port Ivory manufacturing facility from Proctor and Gamble in 2000. This out of date facility is adjacent to PANYNJ's marine terminal leased to New York Container Terminal ...

POLA Pier 500 Planning, Hydrodynamic and Berthing Studies

Ports 2013, 2013
The Port of Los Angeles (POLA) proposes to expand the existing Pier 400 landfill by adding approximately 200 acres of landfill extending south on the east side of the existing facility. The new landfill will be known as Pier 500 Container Terminal. In order to optimize the size, orientation, and - ultimately - the configuration of the terminal, various

Planning and Design of Fixed Berth Structures For 300,000 to 500,000 DWT Tankers

Offshore Technology Conference, 1972
ABSTRACT The planning and design of berths for mammoth tankers completed during the past few years and now under construction, is reviewed. All these structures are of the fixed type and accommodate tankers larger than 300,000 DWT.

Minimum time-energy trajectory planning for automatic ship berthing

IEEE Journal of Oceanic Engineering, 1995
A ship optimal trajectory planning method based on the dynamic model of the ship is presented. First a mathematical modular model is introduced for describing the non-linear dynamics of the ship. Then the problem of optimal trajectory planning is discussed.
