3 (Rev-0)

3.5 Pre-surface preparation test coupon. In order to ensure production of required surface profile, the Contractor shall accomplish the following, tasks, whenever abrasive-blasting is required in a work item that is deemed a

”critical-coated’ surfaces:

3.5.1 Coupon material and test set-up particulars.

3.5.1.1 Conduct a performance test on all abrasive blasting operations on a Contractor- provided test coupon, prior to starting abrasive blasting operations on the vessel. Ensure the following:

The coupon shall be a new metal plate, of the same metal type and material properties as the vessel area to be blasted - steel or aluminum plate, as applicable, and shall have no existing anchor profile - other than the surface irregularities from the manufacturing process.

The test coupon shall be flat, with nothing welded to the side used for the anchor profile test, no thinner than a 1/8-inch plate and measuring no smaller than 1-foot by 1-foot.

For steel substrates, the coupon shall have the mill scale intact, and be in a Rust Grade "A" condition, in accordance with SSPC-VIS 1.

The test coupon shall be affixed so as to not permit excessive movement during the performance test, but shall not be affixed to the vessel.

3.5.1.2 Ensure that the abrasive-blasting operation for the test coupon is conducted with the identical setup and parameters that will be used blasting the designated vessel surfaces – including, but not limited to:

The abrasive media type and media size selected to achieve the anchor profile range, as specified in the applicable work items.

Nozzle size and type (straight bore, high velocity nozzle, angle nozzle...).

Delivery rate and pressure settings.

3.5.1.3 Blast a one-square foot area on one side of the test coupon to the abrasive surface preparation standard specified in the work item, and perform an anchor profile test of the blasted surface in accordance with ASTM

D4417, Method B or C. Notify the COTR in advance of the abrasive blasting operation test, to permit the witnessing of the test by the COTR. Submit a CFR documenting the results of the abrasive blasting operation test. The CFR shall include at a minimum, the following:

Area of the vessel for which the verified setup will be used to abrasive blast.

The selected abrasive media type and size.

The nozzle size and type.

The delivery rate and pressure.

The test coupon starting properties (material type and surface conditions).

The resultant anchor profile readings from the test (a minimum of 3 locations, separated by a minimum of

2 inches shall be recorded).

NOTES

1. A performance test of the abrasive blasting operations on a test coupon and measuring the resultant anchor profile prior to performing the abrasive blasting operation on the cutter is required. The test coupon will be used to evaluate the anchor profile produced by the equipment setup and selected abrasive media.

2. The reverse side of the test coupon may be used for the subsequent test, provided that the conditions in paragraph 3.5.1 (Coupon material and test set-up particulars) are met.

4 (Rev-0)

3. Ultra high pressure water jetting does not create an anchor profile and is exempt from the anchor profile test coupon check.

3.5.1.4 Repeat the abrasive blasting operation test in the following instances:

The equipment setup, that was evaluated during the test coupon abrasive blasting performance test in paragraph 3.5.1 (Coupon material and test set-up particulars), has changed.

The resultant anchor profile readings observed on the vessel are outside the specified anchor profile range.

Media is changed from MIL-A-22262 to CID A-A-59316 or vice versa.

The supplier of the abrasive blasting media changes, regardless if the new source for the media has the same specifications.

When Directed by the COTR.

CAUTION!

Ensure that blast media from the performance test does not strike the vessel during the test.

3.6 Interim changes to SFLC Std Spec 0000. The Contractor shall be aware of the fact that the requirements of paragraph 3.3.2.1.1 (Water depth) have been revised to read as follows:

“3.3.2.1.1 Water depth. Ensure that water depth is sufficient at the pier to allow the vessel's lowest underwater appendage to clear the bottom by at least two feet at:

Ordinary low water mark on non-tidal rivers.

At all tide conditions predicted during the availability for tidal rivers and other navigable waterways (Bay, Lake, etc.).”
