Is there a minimum annual vessel visit threshold for determining a fleet's applicability?

For example, if a company has vessels visiting the Port of Long Beach and vessels visiting the Port of Oakland, the company is considered to have two separate fleets, one a POLA/POLB-based fleet and the other a Port of Oakland-based fleet. If a company has vessels that visit POLA and vessels that visit POLB, all of those vessels collectively are considered one fleet (POLA/POLB fleet), as these two ports are considered one port for purposes of complying with this regulation. A company will have a separate fleet for each port its vessels visit. Similarly, terminals and ports that only receive these types of vessels are not affected by the regulation.

Fleets in other ocean-going vessel categories (i.e., tankers, vehicle carriers, and bulk and general cargo vessels) are not affected by the regulation. Are fleets in ocean-going vessel categories other than container vessels, refrigerated-cargo vessels, and passenger vessels affected by the regulation? Since the port of Long Beach and the port of Los Angeles are considered one port under the regulation, the five vessels that go to Los Angeles and the four vessels that go to Long beach make up CARB Shipping's Los Angeles/Long Beach fleet. The seven vessels that go to Oakland make up CARB Shipping's Oakland fleet. Four of the vessels go to the port of Long Beach for 20 visits. Five of the vessels go to the Port of Los Angeles for 30 visits. Seven of the vessels go to the Port of Oakland for 40 visits. Terminals located at ports above receiving types of fleets identified aboveĪ fleet is defined in the regulation as owned or chartered vessels of one vessel type that visit the same port and are under the direct control of the same company.įor example, the fictitious company CARB Shipping charters 10 vessels. Ports of Los Angeles (POLA), Long Beach (POLB), Oakland, San Francisco, San Diego, and Hueneme The following table identifies the regulated parties.Ĭontainer vessel fleets, refrigerated-cargo vessel fleets, and passenger vessel fleets The purpose of the regulation is to reduce hoteling (or at-berth) emissions and associated health impacts from diesel auxiliary engines onboard vessels docked at California ports. New compliance requirements for the At Berth Regulation go into effect beginning on January 1, 2023. To see the updated FAQs developed for the 2020 At Berth Regulation, click here. The results show that the proposed model and algorithm can ensure safety and improve the efficiency of vessel transportation scheduling simultaneously.The following FAQs, developed for the 2007 At Berth Regulation, remain relevant until December 31, 2022. Compared with the simple genetic algorithm (SGA) and the “first come, first served” (FCFS) method, the total waiting time, scheduled time, and maximum waiting time are decreased significantly through SAMPGA. Calculations indicate waiting and total scheduled times of 485 min and 342 min, respectively, for 10 vessels and 1731 min and 456 min, respectively, for 20 vessels. This study simulates numerical examples for 10 and 20 vessels. Furthermore, it applies a simulated annealing and multiple population genetic algorithm (SAMPGA) to solve the proposed model for vessel transportation scheduling in port. Therefore, in consideration of scheduling order, travel direction and distance of the berth, a mathematical model with minimum total waiting time as the objective function is established. This study aims to improve the efficiency of vessel transportation scheduling by coordinating channels and berths. Channels and berths are important resources for vessels in port operation.
