Prigorodnoye Export Terminal Port Regulations Rev 01
29.5 Vessels arriving in the Inerted Condition
Vessels may only arrive at the terminal inerted following new build or refit.
Vessels arriving to load at the terminal with tanks in the inerted condition will be required to
handle the vapour generated utilising the on board systems until the CO2 content of vapour in
the ship’s tanks is 1% or less.
Inert tank vapour may initially be discharged to atmosphere until a hydrocarbon content of 8%
is recorded at the ship’s vent stack, at which stage the CO2 content of the vapour should be
sufficiently low enough to support combustion of vapour in the ship’s boiler, if permitted in
section 26.2. This process should continue until the CO2 content of the tank vapour reaches
1% or less at which time the terminal may accept vapour as boil off gas (BOG) to shore flare
system as in section 29.6.
29.6 Re-gasification & Cooldown
All ship’s tank vapour will initially be routed to ship’s vents until hydrocarbon level reaches
>8% by volume after which vapour may be diverted to shore flare system. The level of CO2 in
the return gas will be monitored ashore until this has been confirmed to be less than 200 ppm.
On ship’s confirmation that CO 2 level is less than 200ppm, the terminal will require a stop in
order to change over the return gas from flare system to the boil off gas (BOG) shore tanks.
It is anticipated that this stoppage will be for approximately five minutes, but every effort will be
made to minimise the time involved. The terminal will continue to monitor the CO2 levels of
the return gas until it is less than 200ppm at which time gassing up will be stopped to permit
changeover of shore return gas from flare system to the shore tanks.
A close liaison between the Responsible Ship’s Officer, The Loading Master and the
Prigorodonoye Control Room will be required during this operation to permit a smooth
operation and best use of vapour recovery with minimal use of flared vapour.
29.7 Single Arm Cooldown
The line up and cool down of the tanker's loading lines will be as per the normal cooldown
procedure in 29.2 except that only one loading arm, will be required to be cooled at this
stage. The loading arm to be used will be advised by the Loading Master at the on board
pre-loading meeting and agreed with the vessel.
After cooldown of the nominated loading arm (at least one hour) flow rate to the tanker will be
adjusted in accordance with the tanker’s requirement.
in
During the latter stages of the cooldown the remaining two loading arms will be cooled down
keeping with the overall flow rate required by the tanker.
At the completion of cooldown loading will be stopped to carry out a ‘cold’ ESD test as above.
29.8 Draining and Inerting of Loading Arms
Draining, purging and inerting of loading arms will be carried out as above section 29.4.
