PART 39_VAPOR CONTROL SYSTEMS--Table of Contents
 
Subpart 39.40_Lightering and Topping-Off Operations with Vapor Balancing
 
Sec. 39.40-5  Operational requirements for vapor balancing--TB/ALL.

    (a) During a lightering or topping-off operation each cargo tank 
being loaded must be connected by the vapor collection system to a cargo 
tank which is being discharged.
    (b) If the cargo tanks on both the vessel discharging cargo and the 
vessel receiving cargo are inerted, the following requirements must be 
met:
    (1) Each tank on a vessel receiving cargo which is connected to the 
vapor collection system must be tested prior to cargo transfer to ensure 
that the oxygen content in the vapor space does not exceed 8 percent by 
volume. The oxygen content of each tank must be measured at a point one 
meter (3.28 feet) below the tanktop and at a point equal to one-half of 
the ullage. Where tanks have partial bulkheads, the oxygen content of 
each area of that tank formed by each partial bulkhead must be measured 
at a point one meter (3.28 feet) below the tanktop and at a point equal 
to one-half of the ullage;
    (2) The oxygen analyzer required by Sec. 39.40-3(a) must be tested 
for proper operation prior to the start of each transfer operation;
    (3) The oxygen content of vapors being transferred must be 
continuously monitored during the transfer operation;
    (4) Cargo transfer must be terminated if the oxygen content exceeds 
8 percent by volume and must not be restarted until the oxygen content 
in the tanks of the vessel receiving cargo is reduced to 8 percent by 
volume or less; and
    (5) The vapor transfer hose must be purged of air and inerted prior 
to starting vapor transfer.
    (c) The isolation valve, required by Sec. 39.20-1(c) of this part, 
located on the

[[Page 509]]

service vessel must not be opened until the pressure in the vapor 
collection system on the vessel receiving cargo exceeds the pressure in 
the vapor collection system on the vessel discharging cargo.
    (d) The cargo transfer rate must be controlled from the vessel 
discharging cargo, and must not exceed the maximum allowable transfer 
rate for the vessel receiving cargo.
    (e) The pressure in the vapor space of any cargo tank connected to 
the vapor collection line on either the vessel receiving cargo or the 
vessel discharging cargo must not exceed 80 percent of the lowest 
setting of any pressure relief valve during ballasting or cargo 
transfer.
    (f) All impressed current cathodic protection systems must be 
deenergized during cargo transfer operations.
    (g) Tank washing is prohibited unless the cargo tanks on both the 
vessel discharging cargo and the vessel receiving cargo are inerted or 
the tank is isolated from the vapor collection line.
