The line said berth congestion related to the Japanese tsunami, bad weather and the Lunar New Year all had a deleterious effect on its performance.
MOL's first quarter performance on all services, including those in which it takes slots but does not operate vessels, was:
' Asia/U.S. West Coast, 93 percent, down from 97 percent in the fourth quarter 2010.
' Asia/U.S. East Coast, 83 percent, down from 86 percent in the fourth quarter 2010.
Transatlantic, 50 percent, down from 85 percent in the fourth quarter 2010.
' Asia/Europe, 92 percent, up from 89 percent in the fourth quarter 2010.
The on-time performance of MOL-operated vessels was poorer on the transpacific but better on the transatlantic and Asia-Europe:
' Asia/U.S. West Coast, 90 percent, down from 100 percent in the fourth quarter 2010.
' Asia/U.S. East Coast, 69 percent, down from 72 percent in the fourth quarter 2010.
' Transatlantic, 56 percent, down from 81 percent in the fourth quarter 2010.
' Asia/Europe, 94 percent, up from 84 percent in the fourth quarter 2010.
MOL provides figures for 23 services, 16 transpacific, one transatlantic and five Asia/Europe. The line considers a vessel on time if it arrives within 24 hours of its scheduled arrival. MOL began reporting its on-time performance in April 2010.
