There are studies underway regarding the phase out of single hull tank vessels in U.S. waters from 2015 to 2010, a move which would have dire conse- quence for many owner/operators while providing a boon in business for builders. According to a recent report from the Department of Homeland

Security and the U.S. Coast Guard, the

U.S. tank barge fleet would be most affected by the accelerated single hull phase out, with approximately 1,650 tank barges - or 38 percent of the total tank barge fleet - losing five years of service life. Overall, approximately 1,700 U.S. and 70 foreign single hull tank vessels would be affected.

After a recent oil spill on the Delaware

River involving a single-hulled vessel,

Congress asked the Coast Guard for information on the impact of changing the final phase-out date to January 1, 2010.

In its report, the USCG reported that all U.S. Tank Vessels less than 5,000 gt would lose five years of service life, with the vast majority affected being barges. (note: it is already required that all single hull tank vessels of 5,000 gt and greater are phased out by January 1, 2010.) # of GT Notes

Tank Vessels 1,648 1,829,630 gt - represents 38% tank barges of U.S. tank barge fleet 26 11,181 gt -represents less than tank ships 1% of U.S. tank ship fleet

Dependent on specific gross tonnage and date of build, U.S. single hull tank vessels that have a double bottom or double sides., built after January 1, 1980, would lose from one to five years of service life. The impact is detailed in the table below.

Depending on specific gross tonnage and date of build, foreign single hull tank vessels that have a double bottom or double sides, built after January 1, 1980, would lose from one to five years of trading life to the U.S. The impact is reflected in the table below.
