6.0 QUALITY ASSURANCE REQUIREMENTS:

6.1 The contractor and all subcontractors, regardless of tier must consult the General Technical Requirements (GTR) to determine the applicability to this work item.

In performance of this work item, the contractor and all subcontractors regardless of tier must comply with the requirements of all applicable GTRs including but not limited to GTRs 1 through 7, 22, 23, 24, 28 and 29.

6.2 Rigging must be accomplished using equipment rated for the full weight of the components being lifted.

6.2.1 Weight of entire assembly is 2980 lbs. (1351 kg)

6.2.2 Removal of the Air Ejectors and valves is permissible in order to decrease the size and weight of the unit for rigging purposes.

6.2.3 At no time will it be permissible for the unit to be off the deck supported by only one lifting appliance. Unit must be supported by two separate pick points / lifting appliances at all times (No single point of failure is acceptable).

6.2.4 Each lifting appliance must be capable of carrying the full weight of the material being lifted i.e. A 1000 lb. part may not be lifted by two (2) 500

lb. chain falls. Both chain falls will need to be capable of carrying the full load of 1000 lbs.

6.2.5 Each lifting appliance must be capable of covering the entire height of a lift without using two lifting appliances in series (No daisy chaining of lifting appliances. i.e. A chain fall may not be directly connected to another chain fall.

6.2.6 All lifting appliances, to include straps and beam clamps, must be affixed with test tags indicating the rated capacity and test date. If the material is new affixed with rated capacity from the manufacturer this requirement may be waived.

6.2.7 Contractor to provide calibrated dynamometer and / or test weights to test all proposed lift points. For estimating purposes a minimum of twelve (12)

6.2.8 Lifting appliances shall be connected to pad eyes or structural members using beam clamps. Lifting appliances shall not be applied to pipes or any other non-structural member.

6.2.9 When rigging through Ellison Doors, door and frame must be removed and reinstalled to avoid damage to the door operating mechanism.

6.2.10 For removal of ladder in the rigging path, contract shall provide barriers to cordon off the area to traffic. This to be a physical barrier, Caution Tape will be considered insufficient.

6.2.11 Removed ladders shall be securely stowed on the deck before rigging equipment through the space.

6.2.12 Fasteners

7.0 STATEMENT OF WORK REQUIRED

7.1 Ship’s Force to Lock Out Tag Out steam / condensate piping components.

7.2 Rig the Air Ejector Condenser and associated Air Ejectors from the upper level of the engine room to Main Deck.

NOTE: Suggested rigging path is through the ladder wells on the port side of the engine room and then aft down the port side passageway of 4th deck to the Cargo Elevator. Contractor to verify dimensions and rigging path during Ship Check.

7.3 Place removed Air Ejectors and Condenser on pallets and protect from weather.

7.4 Open crate and remove new Air Ejector and Condenser Assembly.

NOTE: Expect assembly to be in one piece. Air Ejectors and components may be removed from Condenser to facilitate rigging.

NOTE: Care is to be taken when opening the crate as it will be re-used for shipment of old Air Ejector Assembly.
