Freight rates averaged $2,417 per FEU, 9 percent below a year earlier.
The company said higher volumes were carried on all trade lanes and that there were stronger pre-Chinese New Year shipments.
It said the lower revenue was due to lower core freight rates, particularly on the transpacific and changes in trade mix, partially offset by improvements in Asia/Europe rates.
NOL said freight rates in the period ending Feb. 5 were 10 percent higher than they were in the last six weeks of 2009 because of increased freight rates on key trade lanes and the implementation of an emergency revenue charge on the transpacific that came into effect on Jan. 15.
