The most obvious source of ships might be Japan. In the 1990's Japan had one of the worlds largest shipping fleets, and in fact it still does.

Japan

The island nation of Japan was one of the few major 20th-century industrial powers to come through the Twilight War without any direct damage. Being an industrial exporter and the center of much international trade and banking, the nation was faced with economic upheaval when the war tore up its trading partners, but through the will of its people it survived and, with its extensive ocean transportation capacity, dominated international trade for decades to follow.

Japan has been a major world trade center since before the Twilight War. After the war, the country's shipping network formed the backbone of international trade for decades.
