General Requirements

1. SCOPE

1.1 Intent. This standard specification invokes general requirements for conducting vessel repairs performed at a commercial contractor’s facility for Coast Guard vessels.

1.2 Term interchangeability. The terms 'Contractor', 'CG Yard', 'NAVSTA EVERETT', 'shipyard', 'Base', and 'Coast Guard Industrial' are used interchangeably in this specification. Where the primary service provider is Coast Guard personnel, references to contractor and other noted descriptors within this specification or within drawings, publications, SFLC Standard Specifications or other commercial and military references are deemed the same as prime service provider.

3.2 Work coordination and preparation. The Contractor must plan all specified vessel work detailed in this specification package to ensure the side scan survey does not necessitate a work stoppage. The Contractor must abide by the following guidance, to facilitate the ultrasonic survey:

• Ensure that all u/w body surface preparation and primer coat application tasks are completed within ten days of lifting the vessel.

• Provide a continuous supply of fresh water at .50 gpm within 50 feet of the vessel with standard hose bib fitting.

• Provide 110 VAC electrical power, and scaffolding or other suitable means of access to bring inspection personnel within one foot of all the body surface inspection areas that are five feet above ground level.

• After completion of the hull survey, and authorized hull repairs, resume/complete u/w body preservation process by applying the second coat of the anti-corrosive coating system, and all anti-fouling paint coats.

• Pay close attention to manufacturer’s recommended practices in regards to paint system overcoat time limitations and required degree of surface cleanliness prior to resuming u/w body coating application.

3.3 Side scan requirements and procedures. The Contractor must ensure the following referring to the Coast Guard drawings listed in Section 2 (References) herein as guidance during the performance of the tasks specified below and submit a CIR.

3.3.1 Testing company and personnel. Provide the services of a qualified ultrasonic testing company, with suitable side scan equipment, to conduct a “Scanning Crawler Automated Test” of the vessel’s u/w hull plating for the presence of metal corrosion and deterioration. Ensure the following:

• All scanning operations are completed by personnel meeting the personnel qualification and certification, as required by contractor process. This contractor-developed personnel qualification and certification process must meet, at a minimum, ASNT Recommended Practice No. SNT-TC-1A.

• An ASNT Level III Analyst is on site, to oversee the project and evaluate the collected data.

• An ASNT Level III or II Analyst is on site, to verify with a hand held gauge all areas on the hull identified as thinner than the specified criteria, in order to expedite all repair procedures.

• Plates where scan data indicating wastage less than 15% of nominal plate thickness must be highlighted in DARK GREEN.

• Hand held UT readings must be taken to verify bad metal areas found with the side scan equipment.

All readings must be provided to the COR and the lowest reading marked on the hull at the bad metal location.

3.3.3.1 Any scanning parameter or scope of work changes, including deviations to the color scheme specified above, must be approved by the KO.

3.3.3.2 The “echo-to-echo” technique, or use of multiple backwall echoes to exclude coating thickness, is not authorized due to unreliability in this application.

3.3.4 Ensure that the side scan inspection area includes the Port, Starboard, and Transom exterior shell plate below the water line, but excludes the following list.

• Areas under and within 6-inches of blocks and side blocks (areas that are accessible 6 inches from blocks and side blocks must be hand scanned.)
