The slot charter agreement between Horizon Lines and Maersk Line on the Trans-Pacific 1 (TP1) service will end in December 2010.

This weekly service currently calls Yantian, Xiamen, Kaohsiuing, Los Angeles, Oakland, Honolulu and Guam.

Horizon Lines operates five vessels in this service. Maersk Line has been utilizing the entire 1100 FFE capacity eastbound, and uses a small amount of space on the westbound rotation.

Empty westbound Maersk Line containers are utilized by Horizon Lines for their West Coast customers to ship cargo to Hawaii and Guam.

"Maersk Line is carefully watching market developments and reviewing customer requirements. Once these are made clear we will release a plan designed to replace TP1 capacity. " said Lars Mikael Jensen, Maersk Line Vice President, Network and Product.
