WORK ITEM 2: SSDG Plenum and Softpatch, Repair

1. SCOPE

1.1 Intent. This work item describes the requirements for the Contractor to renew the seal between SSDG aluminum softpatches and the steel main deck plating as designated below. While the softpatch(es) are removed identify and correct all other discrepancies associated with the softpatches and surrounding structure that can be performed most economically while the softpatches are removed.

TABLE 1 – KNOWN DISCREPANCIES

SOFTPACH DISCRIPTION OF DISCREPANCIES

PORT DISCREPANCY: Both soft patches are failing, allowing water intrusion into the generator room on both sides, with more extensive damage on the STBD side. There is water dripping onto the generator and corrosion on the deck and patch itself. About 1/4 of the entire gasket is visibly damaged as identified from the weather deck. Corrosion is apparent along approximately 20' of the gasket. Estimated 2" on either side of the gasket need PPP, likely including the lip where the patch rests. Without removing the non-skid, an estimated total of 10 sqft of metal needs PPP.

On the port side, there is salt buildup on the overhead in the generator room, indicating the gasket is failing, an estimated total of 2 sqft of metal that needs PPP.

STBD DISCREPANCY: Same as PORT, see above.

19 (Draft-1) mast surface (for pricing purposes), and then apply one finish coat, 6 mils or less, to the entire mast for aesthetic purposes. Abide by all the safety, preservation, and quality control requirements specified in SFLC Std Spec 0000, paragraph titled "Preservation requirements – general”.

NOTE

Surfaces being preserved are considered "critical-coated surfaces".

3.5 Weather proofing of connections and reinstallation. The Contractor shall verify that final electrical re-connections of all removed equipment are weather tight. At a minimum, perform the following.

3.5.1 Weather proofing of coaxial cable connectors. Clean the entire plug. Apply a commercially available dielectric compound (e.g. Dow Corning #4 or equivalent) to the interior and exterior including the insulation portion and the threads. Do not fill the air space in the plug with dielectric compound as this will change the impedance and cause a mismatch. Assemble the plug finger tight and tightly wrap a single layer of a commercially available ¾” wide synthetic resin tape with a 50% overlay over the entire plug and for a distance of two inches on each side. Then apply a layer of friction tape and at least 3 coats of a commercially available sealing compound (e.g. 3M™ Scotchkote™ Electrical Coating or equivalent).

3.5.2 Weather proofing of Non coaxial electrical or electronic connectors. Apply a commercially available dielectric compound (e.g. Dow Corning #4 or equivalent) to the interior portion of the connector threads. Encapsulate the connector termination and at least 3 inches of the interconnecting cable and/or MS series panel mount connector with a commercially available plastic electrical insulating adhesive tape. Seal this transition with a commercially available multi-purpose silicone sealing compound (e.g.

Dow Corning 732 Multi-Purpose silicone sealing compound or equivalent) that conforms to MIL-A- 46106. Do not apply silicone sealing compound directly to the metal connector surfaces as a slight corrosion will occur.
