Approximate route of the tugboat Spence and barge Guantanamo Bay Express
Tugboat Spence and her barge Guantanamo Bay Express are owned by the American shipping company TransAtlantic Lines LLC. Together, they make a twice-monthly trip between Naval Station Mayport; near Jacksonville, Florida; and Naval Station Guantanamo Bay in Cuba. Each leg of the trip takes approximately 4 1⁄2 days and covers approximately 1,000 miles (1,600 km). Unloading the barge can take up to five days.
On 13 June 2001, TransAtlantic Lines won a contract with an estimated cumulative value of $16,738,001 for dedicated ocean liner cargo service to US military installations in Guantanamo Bay, Cuba. This contract extended until 30 June 2004. The government announced the requirements for the charter on the World Wide Web on 4 December 2000, and seven bids were received. Military Traffic and Management Command in Alexandria, Virginia, is the contracting activity.
On 14 February 2002 the Department of Defense announced an award of contract DAMT01-02-D-0025, a $17,923,770 firm-fixed-price contract for the tug and barge combination. The contract required provision of international cargo transportation services using ocean common or contract carrier offering regularly scheduled commercial liner service for requirements that may arise in any part of the world. Contract requirements included provision of dedicated ocean, inter-modal, and related transportation services primarily between the Continental United States and Naval Station Guantanamo Bay, Cuba. There were seven bids solicited on 26 September 2001, and seven bids received. The Military Traffic Management Command located in Alexandria, Virginia was the contracting activity.
On 11 November 2004, while leaving Mayport, Florida en route to Guantanamo Bay, Cuba, the tow wires connecting the tug and barge parted, causing the barge to run aground. At the time of the accident, the vessels were experiencing 30-knot (56 km/h; 35 mph) wind gusts and 12-foot (3.7 m) seas. Extensive bottom damage and breaches to all port side voids were reported. The barge was refloated and delivered to the owners the following day. The vessels were owned by Pac-Atlantic Marine Leasing, LCC at the time.
