HEATING Ensure Cargo tank temperatures are maintained [Insert here maxm allowed temperature for the cargo] . Hourly record shall be maintained.
CARGO DISCHARGING OPERATION Before Discharging starts, the C/O will be in the CCR, Officer Of Watch to oversee the situation. 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 STAGE When Terminal representative informs ship of shore’s readiness to receive cargo, For Grade 1 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. 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: 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. 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.
WHEN 75% of CARGO REMAINS ON BOARD Continue discharging Bulk cargo. 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.
BALLASTING No Ballasting by WBP at at this stage. WHEN 50% of CARGO REMAINS ON BOARD Continue 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.
BALLASTING Adjust 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 STAGE Continue bulk discharge of cargo. De-bottom Slop S and SHUT when reached 12.00 mtrs ullage. By now, vessel shall have trim by stern between 5.0 to 6.0mtrs and about 0.5degree LIST to PORT. Reduce COTP speed to avoid cavitation. When 1COT reach 18 m , put AUS on auto mode. [SHUT any Pump and bottom crossover v/vs if OPEN] Strip dry Grade 1 COTs . Reduce COTP 1 and Line Up for Eductor. OPEN [Insert v/v nos] and SHUT [COTP Suction V/V] for drawing cargo from Slop (S) for drive of Eductor.
DISCHARGE SLOP TANK ASHORE - CRITICAL STAGE Confirm Shore line is OPEN Reduce pump speed to minimum, SHUT DC1 [Insert COTP Disch V/V ] and OPEN P/P Rm Disch v/v [105] Increase COTP speed slowly and slowly OPEN DC1 [Insert COTP Disch V/V no.]
Prepare stripping pump OPEN [ST01, ST02, ST03, ST20, ST23, E05, SPS/SSS Insert stripping line v/v nos.] Confirm OB6, ST05 & ST04 are SHUT. AUS in auto mode limit DC1 opening. When Slop P/S EMPTY, SHUT SPM/SSM, DC1 . STOP COTP1 by emergency trip when on min 700 rpms Close manifold v/v 108 . OPEN DR01, DR11, DR12, DR13 . Strip RED lines and pump via Marpol line to shore. When empty, STOP STRIPPER PUMP. PUMPMAN SHALL ALWAYS BE IN PUMPROOM WHEN STRIPPER PUMP RUNNING. HE SHALL FREQUENTLY REPORT THE CONDITION OF THE STRIPPER PUMP TO ENSURE NO HAMMERING OR LEAKAGE OCCURS.
FINAL BALLAST CONDITION Once all Cargo lines are drained, Fill up Ballast tanks [Insert here the WBT nos for final Ballast]
DISCONNECTION OF MANIFOLDS - CRITICAL STAGE Disconnection of Manifolds shall be supervised by OOW. Ship's crew shall remain at state of heightened alertness for any spillage during disconnection. The remanent of cargo in manifold, while disconnecting, shall be collected in the drip tray and drained into COT 4 [Insert here COT No.] . Drip trays shall be immediately wiped clean after draining. After disconnection of manifolds and cleaning of Drip tray, all SOPEP and FFE shall be returned to original storage position. Prepare vessel for sailing.
PREPARATION FOR COW 1. When COT [Insert COT nos. for COW h ere] are initially stripped, Bottom Wash ( COW) will commence 2. Before Commence COW, be sure that all COW Master and local COW machine's valves are SHUT. 3. Check atmosphere of COTs to be washed for O 2 content - MUST be less than 5%, preferably about 3%. O2 measurement to be carried out at 1m below deck and at half of the ullage space (approx. 9m) 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.
Complete the Tanker Operation Check list (DD-0708A-00) Part AR-5"COW Check list (Before COW) COW will be performed using COTP No. [Insert COTP no. same as Eductor] Open valve TC2 and drain valves at the fore end of COW line.Open machines valves Slowly open TC1 to 10%.When cargo passing, drain valves order to shut. Open COW machine's valves Open valve TC1 and increase the pressure up to 0.9 MPa.Keep deck hands standby at the master valve COT 4W [Insert here the 1st set of COT to be COWed] Check COW line for leaks.If any leak identified, immideately SHUT TC1 and OPEN Master valve of COT 4W to depressurize the line If no leaks detected, slowly open TC1 to FULL & Master valve of COT 4W. C onfirm all machines working properly Complete Tanker Operation Check list (DD-0708A-00) Part AR-6 COW Check list (During COW) COW machines must be adjusted in advance for Bottom Wash cycle 035-0-035. During COW, eductor shall be running only for the tanks being washed. Make sure driving pressure abt 0.8 ~ 1.0MPa. During COW, deck lines s hall be constantly monitored for any developing leakages. When COT 4W stripped, OPEN Local valves for COT 1W [Insert here the next set of COT to be COWed] and then OPEN Master valve for COT 1W , check that machines running properly. Repeat Step 12 ~15 for all COTs whih are scheduled for COW. When washing cycle for Last COT for COW is complete, reduce the COTP speed, SHUT the Valve TC1 and leave the Local Machine's valves OPEN to drain the branches for this COT. Continue to Strip the COTs till empty. On completion of Stripping, put the COTP to Discharging Mode and drain the COW Line in Slop Port. Fill in the Tanker Operation Check list (DD-0708A-00) Part AR-7"COW Check list (After COW) When COW line becames Empty, Close all COW Master and Local valves for the Cow Machines. Set the nozzle of each machine to Zero.
