ABS classes first USA built CSR tanker

17 Jul 2007

ABS confirmed it will class the first common structural rules (CSR) tankers built in the United States. Three shallow-draft 49,000 dwt Jones Act product tankers built for Texas-based AHL Shipping Company are currently under review by the society.

ABS is most familiar with the tanker design having been involved since 2004 when it applied its proprietary SafeHull analysis to the initial design. SafeHull is a dynamic-based ship design evaluation system founded on engineering first principles.

According to Tom Kirk, Director, Technology & Business Development, ABS Americas, this design was originally intended to meet ABS SafeHull standards but has been upgraded to meet the CSRs adopted by IACS which came into effect in April 2006. Further enhancements have enabled the tankers to meet requirements for Type II Chemical Tanker per the IMO?s International Bulk Chemical (IBC) Code.

The vessels will be the first of this size to be built in the USA using modular construction. Hull construction and final assembly of the vessels will be conducted at Alabama-based Atlantic Marine Alabama LLC, with several other shipyards and specialty companies under contract with AHL also participating. ABS surveyors at various locations will monitor that the tankers are being built to ABS and CSR standards.

The vessels are scheduled to go on long-term time charter to Shell Trading USA by late 2009 through late 2010.
