Lightering Zones

These data represent federal and state lightering zones within U.S. waters. Lightering is the transfer of oil in bulk from one oil tanker less than 150 gross tons to another oil tanker less than 150 gross tons, or of hazardous material in bulk from one vessel to another. Lightering is often used to reduce vessel draft prior to entering a port. A lightering zone is an area where lightering is either designated, prohibited, has traditionally occurred, or where restrictions are in place to ensure or constrain lightering activities.

本数据集收录美国水域内联邦及州级管辖的过驳作业区（lightering zones）。过驳作业（lightering）指将总吨位小于150总吨的油轮所载散装油料，转移至另一艘同吨位等级的油轮，亦或是将散装危险货物从一艘船舶转移至另一艘船舶。过驳作业通常用于船舶进港前降低其吃水深度。过驳作业区是指可开展指定过驳作业、禁止过驳作业、传统上用于过驳作业，或是设有相关规则以规范或保障过驳作业活动的水域区域。
