Foss Leases Tugs from Signet Foss Maritime Company announced that it will enter into an alliance with Houston-based Signet Maritime Corporation. As part of this alliance, Foss will add to its fleet of tanker escort and assist vessels by leasing two new advanced Z-drive 30 meter, 80 metric tonne (AZ 30/80) tug boats from Signet. Foss officials said they decided to enter into the agreement with Signet both because of anticipated growth and to respond to the needs of its customer base. The first of the leased vessels will join the Foss fleet in February 2008, and the second in May 2008. As part of Foss’ ongoing fleet development plan, one vessel is slated to be assigned to the North Puget Sound, and the second to one of the other West Coast ports Foss serves.
