Built in 1968 by Albina Engine and Machine Works of Portland, Oregon as the Momi (hull #403) for the Hawaiian Tug and Barge Company of Honolulu, Hawaii.

In 1977, the company's corporate name was changed to the Dillingham Tug and Barge Corporation of Honolulu, Hawaii.

In 1986, the Dillingham Corporation shed its maritime assets in favor of real estate investment, with Dillingham Tug and Barge and Young Brothers being acquired by Hawaiian Electric Industries Incorporated (HEI) of Honolulu, Hawaii. At this time, Dillingham Tug and Barge's corporate name was reverted back to Hawaiian Tug and Barge.

The tug is no longer documented. Her current and/or final fate is not known.
