Dear Mr. Jones:

In response to your email dated September 25, 2014 (MSC Document No. 1417424), we have

reviewed the pressure drop calculations for multi-breasted tandem loading. Reference (a) is

“Examined.”

These barges have vapor control systems previously approved by references (b) and (c), and are

acceptable for dual loading operations. Based on the calculations in reference (a), tandem

loading is limited to simultaneous collection of those cargoes listed in the vessels’ CAA at a

maximum transfer rate of 6,000 bbl/hr per barge.

For the OCMI’s convenience, we have included the following recommended COI endorsement:

In accordance with 46 CFR Part 39, excluding part 39.4000, this vessel's vapor collection

system has been inspected to the plans approved by MSC Letter C1-1303733 dated

February 7, 2014 and updated by MSC Letter C1-1402176 dated July 2, 2014 and has

been found acceptable for the collection of bulk liquid cargo vapors annotated with "Yes"

in the CAA’s VCS column of the vessel’s Cargo Authority Attachment.

The VCS system has been approved with a pressure side 3 psig P/V valve with Coast

Guard Approval 162.017/167/4. The cargo tank top is suitable for a maximum allowable

working pressure (MAWP) of 3.5 psi.

When the vessel is carrying cargoes containing greater than 0.5% benzene, the person in

charge is responsible for ensuring the provisions of 46 US Code of Federal Regulations

Part 197, Subpart C are applied.

In accordance with 46 CFR Part 39.1017 and 39.5000(e) this vessel's VCS has been

evaluated and approved for multi-breasted tandem loading with other vessels specifically

approved to tandem load with this vessel.

If you have any questions concerning our review, please contact Lieutenant Dixon Whitley at the

number listed above.
