In contrast to the neighboring Port of Los Angeles, where container cargo volumes fell last month, Port of Long Beach officials reported a nearly 8 percent increase in April container cargo volume compared to the same month last year.

The amount of cargo moving through the port rose 7.9 percent to nearly 614,900 containers, the largest number that has moved through the port in April in the past nine years, officials said.

The number of imported containers grew 7.3 percent to nearly 317,400, while exported containers fell 6.1 percent to more than 137,500 containers. The number of employ containers sent overseas to be refilled shot up 25.3 percent.

Port officials also said that at the end of April, container ships were no longer anchored offshore waiting to berth at the port. During the fall and winter of 2014 and into the first few months of this year, congestion at the twin ports forced containers vessels to wait offshore for days at a time. The congestion stemmed from operational issues and labor strife between shipping companies and dockworkers.

At the neighboring Port of Los Angeles, which reported April container cargo numbers Friday, volume fell more than 6 percent from a year ago. Officials there said the last months’ figures were lower because last April’s cargo volume was higher than normal as cargo owners, anticipating labor strife, brought in additional orders.
