3. REQUIREMENTS

3.1 General. The Contractor shall conform to all requirements specified in SFLC Std Spec 0000 and in this item, as applicable, during the performance of this availability.

NOTE

The requirements of paragraph 3.1 (General) applies to all work under the scope of this contract, whether explicitly stated in work items or not, and also to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.2 Contractor-provided fire watch personnel. The Contractor shall provide fire watch personnel and equipment.

3.3 Welding and brazing requirements. The Contractor shall perform all welding and allied processes, and NDI in accordance with SFLC Std Spec 0740.

3.4 HW disposal. The Contractor is considered as the generator of all contract-generated hazardous wastes and shall use its facility’s EPA generator ID number for management, transportation, and disposal of said hazardous wastes. Ensure the following:

3.4.1 Contractor’s hazardous waste handlers shall comply with applicable requirements of 40 CFR 262.

3.4.2 All contract generated hazardous wastes shall be packaged in 49 CFR-compliant containers.

3.4.3 The designated wastes shall be disposed of at a state or Federally-approved and permitted HW TSDF.

3.4.4 Name of destination TSDF shall be submitted to the KO at the Arrival Conference.

3.5 Interim changes and additions to SFLC Std Spec 0000. The Contractor shall be aware of the following interim changes and additions to the 2009 Edition of SFLC Std Spec 0000:

3.5.1 Acronyms and term definitions – paragraph 1.3 (Acronym and term definitions).

3.5.1.1 The term “COTR” has been replaced with “COR”, which is defined as follows:

“COR”: Contracting Officer’s Representative – the person delegated by the KO as the on-scene representative for matters concerning performance of work; this includes correctness, timeliness, and quality of the Contractor’s work. Normally, the CO/OINC is designated the COR.”

3.5.1.2 Definition addition for the term “Ungrounded, as follows:

· “Ungrounded”: A power system where all of the current-carrying conductors and windings (including any neutral connection) are insulated from ground. In contrast, a generator or transformer in which at least one conductor or point (usually the midpoint or corner of a delta winding or the common center of a wye winding) is intentionally grounded, either solidly or through an impedance, is considered grounded. Note that the distinction concerns only current-carrying conductors; for both ungrounded and grounded power systems, non-current carrying metal parts and equipment grounding conductors are always bonded to earth ground for personnel safety. At non-Governmental facilities, dockside wye connected transformer secondary windings are almost always grounded and are generally not suitable for connection to a Coast Guard cutter without a separate Contractor furnished isolation transformer.”

3.5.2 Changes to paragraph 3.2.4 2.3 (QP-1 Inspector or Tech Rep duties).

“3.2.4.2.3 QP 1 Inspector or Tech Rep duties.

3.2.4.2.3.1 The Coating Inspector for the “QP 1-certified” Contractor or the Contractor-provided NACE-certified Tech Rep shall remain on site, to perform the following duties, as applicable, for each work item that involves preservation of “critical-coated surfaces”:

· Verify inspection instrument calibration.

· Verify and approve the suitability of ambient conditions before surface preparation is begun, and before each coat of paint is applied.

· Verify all aspects of surface preparation – including, but not limited to:

· Cleanliness of compressed air.

· Adequacy of solvent cleaning.

· Proper handling of blast media.

· Actual surface preparation procedure.

· Inspect and approve final surface preparation, before application of primer coat.

· Supervise and approve coating system preparation and application procedures, including but not limited to: mixing and thinning, stripe coating application, spray techniques, and film thickness measurements and recordings.

· Determine when applied coats have sufficiently cured for overcoating, or for system service resumption (see paragraph A2.1.18 (Critical drying time requirements)).

· Complete and sign the quality assurance (QA) inspection forms (see QA-1 thru QA-5), provided in Appendix A (Requirements for Preservation of Ship Structures) of this document.

· Submit all completed QA inspection forms to the COR (through the Contractor), upon completion of work.

3.2.4.2.3.2 The Contractor shall ensure the NACE Inspector is formally informed - via suitable subcontract documentation- and is willing and able to perform of all duties listed above. Submit documentation of this contract and assumption of duties to the KO at the Arrival Conference.”

3.5.10 Pre-surface preparation requirements – additional to paragraph A2.1.7 (Pre-surface preparation requirements).

“A2.1.7.4 Coupon test. 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:

A2.1.7.4.1 Conduct a performance test on all abrasive blasting operations on a Contractor- provided test coupon, prior to starting abrasive blasting operations on the vessel. Use a new metal plate, of the same metal type and material properties as the area to be blasted, steel or aluminum plate, as applicable. For steel plates, the new plate shall have the mill scale intact and the plate will be in a Rust Grade "A" condition, per the SSPC-VIS 1 visual standard cards. No existing anchor profile, other than the surface irregularities from the manufacturing process are permitted on the test coupon. 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. The test coupon shall be affixed so as to not permit excessive movement during the performance test.

CAUTION!

Do not affix the coupon to the vessel nor shall the blast media from the performance test strike the vessel during the test

A2.1.7.4.2 Ensure that the abrasive blasting operation test on the test coupon is with the very same setup that will be used to blast the vessel. The setup shall include, but not be limited to:

· The abrasive media to be used (material and media size).

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

· Delivery rate and pressure settings.

A2.1.7.4.3 Blast an one-square foot area on one side of the test coupon to the abrasive surface preparation standard specified in the applicable work item and perform an anchor profile test of the blasted surface in accordance with ASTM D4417, method A or C. Notify the COR in advance of the abrasive blasting operation test, to permit the witnessing of the test by appropriate Coast Guard personnel. Submit a CFR documenting the results of the abrasive blasting operation test. CFR shall include at a minimum, the following:

· Area of the vessel that the verified setup will be used to abrasive blast with.

· The abrasive media used.

· 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.

NOTES

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

2. The reverse side of the test coupon may be used for the subsequent test, provided that the conditions in paragraph A2.1.7.4 (Coupon test) are met.

A2.1.7.4.4 Repeat the abrasive blasting operation test in the following instances:

· The setup, as defined in paragraph A2.1.7.4.1 is 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 COR.”

NOTE

A performance test of the abrasive blasting operations on a test coupon and measuring the anchor profile prior to performing the operation on the cutter, in order to confirmed that the anchor profile range that the operation is going to produce. An abrasive blasting operation test is prudent, as there are enough variables in the equipment setup and media properties that the resulting anchor profiles from one contractor to the next vary significantly.

3.5.11 Post-surface preparation requirements - additional to paragraph A2.1.8 (Post-surface preparation requirements).

A2.1.8.8 Substrate profile measurements - during and post-surface preparation. 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 for complete preservation of a ”critical-coated” surface:

A2.1.8.8.1 During surface preparation by abrasive blasting or waterjetting operations, spot check the existing anchor profile per 500-square feet, in order to 'project' the need to manage the excessive anchor inspect for both excessive and insufficient anchor profiles . When the Contractor elects to prepare a substrate by waterjetting, the Contractor shall inspect the substrate for areas of insufficient or excessive anchor profile, both visually and in accordance with ASTM D4417, Method A or C. Submit a CFR detailing the location, square footage, measured anchor profiles, and the anchor profile range required for the applicable coating system.

A2.1.8.8 2 Post completion of surface preparation, measure the profile of the resultant bare surfaces, in accordance with ASTM D4417, Method A or C.”

3.5.12 Caution verbiages – additional to paragraph A2.1.18 (Critical drying and cure time requirements).

CHECKPOINT 9 – FINAL INSPECTION

Verify final system dry film thickness. Conduct 5 sets of 3 readings for each of the first 3 100-sqft areas, followed by 5 sets of 3 readings for each succeeding 1000-sqft area.

Ensure that system cure is in accordance with manufacturer's recommendation for intended service.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure, to exhaust all solvent to the atmosphere and to prevent solvent entrapment.

For immersion coatings (including tank U/W body), record date and time of the following events:

Final coat application: _____/_____; Return to service or removal from environment controls: _____/_____

CHECKPOINT 10 – RECORD KEEPING

Complete, sign, and submit all provided QA Inspection Forms.

QA-2 - QUALITY ASSURANCE INSPECTION FORM
