One watch-keeper will be monitoring the opposite side of the connected manifolds and the sea surface.Another watch-keeper will be stationed at the manifolds area will be monitoring the pipelines on the side of connected manifolds. The third watch-keeper will be patrolling the deck. The pump man will be in the pump-room to operate valves as ordered by Chief Officer.

COMMENCING CARGO DISCHARGING – CRITICAL STAGEWhen Terminal representative informs ship of shore’s readiness to receive cargo,

For Grade 1 cargo:

Start COTP for 1st grade of cargo and increase RPM to 900 and slowly OPEN the discharge v/v.Ensure there is no leakage in Pump room, on deck and that off shore side manifold pressure gauge shows ZERO pressure. Ensure no oil sheen observed in water around ship. Once, Terminal confirms receiving cargo,increase COTP revolutions to max or till max agreed manifold pressure. Double check that cargo is being discharged from the intended Cargo tanks. For Grade 2 cargo:

Start COTP for 2nd grade of cargo and increase RPM to 900 and slowly OPEN the discharge v/v.Ensure there is no leakage in Pump room, on deck and that off shore side manifold pressure gauge shows ZERO pressure. Ensure no oil sheen observed in water around ship. Once, Terminal confirms receiving cargo,

increase COTP revolutions to max or till max agreed manifold pressure. Double check that cargo is being discharged from the intended Cargo tanks.For Grade 3 cargo:

Start COTP for 3rd grade of cargo and increase RPM to 900 and slowly OPEN the discharge v/v.Ensure there is no leakage in Pump room, on deck and that off shore side manifold pressure gauge shows ZERO pressure. Ensure no oil sheen observed in water around ship. Once, Terminal confirms receiving cargo,

increase COTP revolutions to max or till max agreed manifold pressure. Double check that cargo is being discharged from the intended Cargo tanks.

Once, this set of COTs reaches level of slack tanks, OPEN other COTs as well for each grade.

BALLASTING

Ensure Cargo tank temperatures are maintained [Insert here maxm allowed temperature for the cargo].

Ensure correct Manifold valve is OPEN, Open suction v/v of designated tanks [Insert cargo tanks with minimum ullage for discharging this grade] to fill up the bottom line and separator.





Ensure that vessel is always kept UPRIGHT. Ensure that vessel is never trimmed by HEAD. Do Not excced max allowed Draft.

WHEN 75% of CARGO REMAINS ON BOARD

Continue discharging Bulk cargo. Maintain hourly record of Manifold pressure, Cargo Temperature,

Ensure that vessel is always kept UPRIGHT. Ensure that vessel is never trimmed by HEAD. Do Not excced max allowed Draft.

BALLASTINGNo Ballasting by WBP at at this stage.

WHEN 50% of CARGO REMAINS ON BOARDContinue discharging Bulk cargo. Commence throttling COTs from Aft to have stagger of atleast 1m difference in Ullages to achieve a trim of atleast 5.0mtrs by stern for stripping and educting purposes.

Maintain hourly record of Manifold pressure, Cargo Temperature, O2 contents of IG and discharge rate with stress calculations. Take rounds of deck and P/P room as per SSSCL.Ensure that vessel is always kept UPRIGHT. Ensure that vessel is never trimmed by HEAD. Do Not excced max allowed Draft.

BALLASTINGAdjust ballast levels to keep vessel upright using WBT 1 (P+S). Gravitate ballast in WBT 1W as much as possible. Ask E/Rm for both the Water Ballast Pumps. Start WBPs one by one with discharge valve SHUT and continue ballasing.

WHEN 25% of CARGO REMAINS ON BOARD - CRITICAL STAGEContinue bulk discharge of cargo. De-bottom Slop S and SHUT when reached 12.00 mtrs ullage.

Reduce COTP speed to avoid cavitation.

EDUCTING - CRITICAL STAGE

If only one Grade of Cargo then switch over to second Group of line and Pump. And similarly third Group.

Refer to section "PREPARATION FOR COW"Once COW is complete, Double check the cargo in COTs by taking dip at all available dipping points. If required educt second time. Keep manifold OPEN to avoid any thermal expansion.
