1.8.1.4 The Unit will contact the servicing ESD or ESU to setup removal/installation of the transducer if Unit personnel are unable to accomplish this task.

1.9 SFLC Standard Specification approved changes. The Contractor must be aware that the following are approved changes to published SFLC 2020 Edition Standard Specifications and supersede published content:

1.9.1 SFLC Standard Specification 8636. Add missing paragraphs between 3.2 and 3.5 of Std Spec 8636 as follows:

1.10 Access cut boundaries. The Contractor shall ensure that access cuts comply with the requirements and restrictions detailed in the following and in SFLC Std Spec 0740, and referenced codes.

1.10.1 Location of boundaries. Boundaries of access cuts and closure plates shall, in general, be located between principal ship framing, bulkheads, and other structural members and shall be at least three inches from any of these members or from the toes of other welds. A reduction in this three-inch minimum may be approved by the KO on a case-by-case basis provided sufficient clearance is maintained for welding and inspection requirements.

The boundaries of access cuts and closure plates should land on existing butts or seams, wherever practicable.

The boundaries of prior access cuts should be utilized wherever possible. Boundaries may extend across one or more frames as required for the size of the opening.

1.10.2 Access hole dimensions and arrangements. Holes or access cuts shall be the minimum size necessary and shall be in accordance with the following:

Rectangular access cuts and closure plates welded into primary hull structure shall be at least 12 inches wide in the lesser dimension.

For circular access cuts, the minimum diameter shall be 4T, where T = thickness of the involved structural member, but not less than three inches.

Circular closure plates for access cuts less than two feet in diameter shall be dished 1/16 to 1/8 inch

NAVSEA S0600-AA-PRO-160/CH16 provides requirements for design, fabrication, and installation of temporary watertight closures.”

to allow for shrinkage when welded.

Corners of rectangular access cuts and closure plates shall have a minimum radius of 6 inches except when a boundary lands on an existing hull longitudinal seam or transverse butt weld.

Corners at an existing seam or butt shall intersect at a 90-degree angle.

Cuts that are to cross existing butts or seams shall do so at an angle of 90 degrees plus or minus

15 degrees.

In primary hull structure, existing welds forming the boundary of a cut shall be cut back 3 inches beyond the toe of the access cut, except that the cut back shall not intersect or cross an existing weld, frame, or structural member. In which case, the cut back may be reduced to a minimum of two inches in length.

Existing welds crossed by the cut shall not be cut back.

1.10.3 Primary hull structure. Primary Hull Structure includes the shell, main strength decks, principal longitudinal bulkheads, vertical keel, deep web girders and stiffeners designed to withstand the ship bending stress.

1.10.4 Mechanically fastened joints. Welding closer than six inches to a mechanically fastened joint should be avoided. When access cuts cross or come within six inches of a mechanically fastened joint, the fasteners shall be checked for tightness and if necessary, loose fasteners shall be seal welded or removed, and replaced for a distance of 6 inches beyond the edge of the cut. When a cut crosses a mechanically fastened seam the cut plates shall be repaired using single V welds backed with glass tape (MIL-C-20079) to prevent fusion between the mechanically fastened plates.

1.11 Ship integrity maintenance. The Contractor shall maintain safety and ship integrity by installing temporary guarding and coaming, in addition to weathertight and watertight closures. Remove these temporary fabrications after closing the hull access, and grind surfaces flush in way of removals. For shell plating cuts made at or below the waterline where temporary closures are impractical, the Contractor shall secure each vulnerable compartment and subdivision to minimize potential damage to the extent permitted by the scope and urgency of the work.

1.11.1 Guarding. Install temporary guards in accordance with 29 CFR 1915.73.

1.11.2 Coaming. Ensure that in areas where flammable liquids may be stored, a 4 inch high metal coaming shall be installed on the surface of the deck with tack welds and fully sealed with caulking compound. The coaming shall encircle the access cut in the deck.

1.11.3 Weathertight and contamination closures. Fabricate temporary closures, using fire retardant material, before cutting access openings and install closures whenever access is not in use. Closures shall be:

Constructed to protect the access from inclement weather and entry of contaminants (shall include a coaming or dam on the deck to redirect rain runoff away from the opening).

Fitted with fasteners that permit rapid installation and removal.

Able to support a minimum of 150 pounds per square foot for horizontal deck closures.

Where the access opening is in way of a removed hatch, scuttle or door, the closure shall be configured to allow normal passage of ship’s personnel and equipment.

1.11.4 Watertight closures. Ensure that access openings created four feet or less above the maximum anticipated waterline shall include temporary watertight closures when the vessel is waterborne.
