Transmarine Navigation

What Transmarine Navigation does

Transmarine Navigation Corporation was a private U.S. maritime services company providing cargo delivery, ship operation, and bulk cargo shipping services, with 85-plus years of specialized expertise in the Pacific corridor. The company served maritime shipping companies and operators requiring port agency and operational support, primarily along the U.S. West Coast and Hawaii. Its core offering was port-side maritime agency services, including coordination of vessel calls, husbandry, and operational support for shipping industry customers — a traditional services business rather than a technology platform. No proprietary technology, digital products, or pricing models were publicly disclosed in the available data.

On July 1, 2025, T. Parker Host, a Jefferson Parish, Louisiana-based maritime services company with a century of East and Gulf Coast operations, completed the acquisition of Transmarine Navigation Corporation. The transaction combined Transmarine's Pacific corridor expertise with HOST's Atlantic and Gulf footprint to create a coast-to-coast maritime services platform covering every major U.S. port, including both coasts and Hawaii. Following the acquisition, Transmarine was integrated and rebranded as HOST-Transmarine, A Horizon Group Company, with the original Transmarine website redirecting to HOST's platform. The company is led by CEO and President Jim Papp. As of the acquisition date, Transmarine no longer operates as an independent entity, and post-acquisition customer relationships, headcount, and revenue are reported within the combined HOST organization.
