Technical data shall contain technical information, specifications, instructions for operation, maintenance of equipment and recommended spare parts list. All copies of technical data shall be legible and written in the English language.

5. LIFTING POINT REQUIREMENTS

5.1. Lift points. If the equipment comes equipped readily liftable via lift points, lift points shall meet the requirements of this section to allow lifting by crane during equipment off-loading, installation, operation, and removal. Lift points shall be located, designed, and marked per the following to ensure the equipment is readily liftable when it arrives.

5.1.1. Integral (i.e., not bolt-on), lifting point items such as lugs, thru-holes, pad-eyes, trunnions, and ISO container corner fittings are suitable for use at PSNS & IMF.

5.1.2. Removable lift points such as swivel hoist rings, eye bolts, etc., are not preferred for use at PSNS & IMF due to the corrosive environment. To be permitted, the contractor must receive approval from the Receiving Activity POC prior to contract award.

5.1.3. Lift points shall accommodate ASME B30.26 common rigging gear (e.g., shackles, wire rope pendants/grommets, etc.).

5.1.4. Lift point allowable strength shall be based on ASME BTH-1 (latest revision), Category B, Service Class 0.

5.1.5. Welding involved shall comply with applicable AWS Standards.

5.1.6. When possible, to maximize stability, locate lift point(s) symmetrically around, and above, the Center of Gravity (CG), on the same horizontal plane. This helps ensure equal length slings converging to a common point will lift the equipment visually level.

5.1.7. Locate the lift points such that the routing of rigging gear is clear of obstructions.

This is to avoid damaging equipment, chafing, etc.

5.1.8. The minimum lift point Working Load Limit (WLL) shall be based on the entire weight of the equipment plus 10%. Account for additional loads induced by 45° sling angles with respect to horizontal.

5.1.8.1. Lift points for three- or four-point lifts shall be sized such that any two points carry the entire load based on worse case load distribution with respect to center of gravity.

5.1.8.2. For padeyes, align their primary planes toward the CG so that the slings do not pull out of plane by more than 5°. Exceptions may be acceptable if they are designed to account for the resultant out-of-plane loading.

5.1.8.3. The use of spreaders, lift beams or strongbacks is not acceptable.

5.1.9. Lift point supporting structures shall be designed to sustain the various loads imparted by the lifting arrangement.

5.1.10. Provide all arrangement drawings, lift sketches, calculations required for the design and usage, and manufacture’s documentation of the lift points. All calculations required for the design of the lift points shall be stamped by a

Professional Engineer. A minimum of ten business days is required for Government reviews and approvals of design(s). The Government will determine if lift sketch labels are required.

5.1.10.1. When required, a lift sketch shall be included in the manual. Lift sketch information shall include, at a minimum, the following:

5.1.10.1.1. The maximum weight of the equipment expressed in pounds.

5.1.10.1.2. The CG location(s).

5.1.10.1.3. The lift point locations and their capacity.

5.1.10.1.4. Recommended minimum sling lengths and capacities.

5.1.11. Permanently label all lift points, or immediately adjacent to them, with the WLL, and test date.

5.1.12. Load test lifting points to 125% (+5%, -0%) of the WLL and hold for at least two

(2) minutes. Acceptance criteria shall be: no bending, cracking, or permanent deformation of the lift points or associated structure. The contractor shall perform load tests plus a pre- and post-load visual inspection (VT) in accordance with applicable standards prior to painting. Documentation of satisfactory results shall be submitted prior to Government acceptance.

5.1.12.1. Alternative to a load test, a magnetic particle testing (MT) of the lift point welds per ASTM E709 is permitted. The acceptance criteria is Section 6.2 of

MIL-STD-2035A, or equivalent standard(s) as approved by the government, provided the testing is performed by a certified third party. Documentation of satisfactory results shall be submitted prior to Government acceptance.
