4. Depth (MLD): 9.754m

5. Load Draft (EXT): 7.530m

6. Min. Draft: 5.18m

7. Total anchor: 10.5 shackles on board currently hold on port 6 shackles.

Requested area for Dehumidification and tasks

1. Accommodation/Living quarters (approx. 7000 cubic meter air volume)

2. 6 Thrusters motor box (approx each 80 cubic meter air volume)

3. 4 cranes engine compartment (approx each 30 cubic meter air volume)

4. Dog house (approx 60 cubic meter air volume)

5. Engine room, Equipment room, SCR room, Prop room, Steering gear room, Generator control room, DP room, Aft communication room, air comp room, electric workshop, Main store, Material office, supervisory control room, air cond room and fire pump room (approx total 14,000 cubic meter air volume)

6. Aft pump room, Mud pump room, mud tank area, BOP accumulator room,ccu room, hydraulic equipment room, sack storeage forward pump room and boiler room (approx total 7,000 cubic meter air volume)

7. Sealing of Removable Catwalk and Flush Hatch with marine weather tight wax tape.

8. Submergible pump to place in moon pool connected to fire line for fire fighting purposes due to no individual sea chest emergency fire pump (currently the fire pump suction on main sea chest which will be blank during cold stackup).

Proposal from ISC

1. Above dehumidification will be dehumidified by 6 medium size of dehumidifier. ( 1 for the accommodation area, 2 for the thrusters motor with crane and dog house), 2 for engine room and surrounded compartment, 1 for the pump room and surrounded compartment).

2. Estimated at least 15 float to be placed with 5 grouping (cement unit room {2}, mud pump room {4}, aft pump room {3}, prop room {3}, equipment room {2} and steering gear room {1})

3. Suspended sacrificial anodes estimated 34 (17 each port and starboard), 26 anodes/steel coupon for ballast tanks.

4. Watchmen hut targeted to build at riser cart track.

5. Boarding free boat about 1.5 meter ( just wood step ladder sufficient)

6. Generator place at aft deck after the drums and container cleared using barge crane. Ship cranes are heavy duty type (over 50 tonnes); No provision crane on board. Advisable to not operate without proper crane certificate.

7. No designated power connection, electrician will identify and spare breaker or direct connection to the bus bar.

8. The capacity of the Layup generator will be decided after confirm the windlass motor starting current requirement. Suspected about 70 kw motor. If the motor DOL starter, at least 500 kVA require for starting. If star/delta then 400 kVA is sufficient.

9. Diesel Oil will be pumped from the ship storage to layup generator use.

10. Desiccant will be use for the electric cabinet. Need to find out the effect from desiccant for electronic cabinet.

11. Scaffolding require for funnel both port and starboard. Material available on board.
