EVALUATION #1: Two man enter into A1 compartment (flooding control, water temp. approx.62 degrees F) were wearing Wet Suits while applying the ProMag and QF-2 seapatch to a 3dia. Hole (A1/BH2 bulkhead damage), 3 above deck with 35-55 psi, patches did not hold. See Photo
EVALUATION #2: Two man enter into A1 compartment (flooding control), water depth was approx. 1, 0 deep to perform emergency hull repair to a 2 1/2 dia. Hole (A1/BH1) in bulkhead 2 ft. above deck with 28-32 psi head pressure (depth of water in W1 was approx. 6 ft.), and applied QF-2, Patches held. See Photo
EVALUATION #3: Rigged two 30 strongbacks across side scuttle door, the strongbacks were attached to magnets beyond scuttle frame. Attached to the strongback were two tightening devices that were use to stop the hatch from leaking by screwing down on them. The scuttle hatch was to the tank, which was flooded to a height of 6 FT. Patches held with no leaks. See Photo
EVALUATION#4: This was the same evaluation as #2, except using a box patch with the QF-2. In this test, the leak could not be stop or even applied to the bulkhead because of too many moving pieces to work with. See Photo
EVALUATION #5: Rigged 30 and 15-10 strongbacks in combination across fwd watertight door, strongbacks attached to magnets beyond watertight doorframe to tank which was flooded to a height of 6 FT. Tightening devices were attached to the strongback and were screwed down onto hatch to stop from leaking. Patches held approximately 90 % of water. See Photo
EVALUATION #6: Rigged K Type Shoring in compartment A1, aft bulkhead, installed magnets as anchor points in overhead and on the deck, there was no simulated movement / pressure during this part of the evaluation. The two magnets held the wooden shores in place in the static pressure application. See Photo
1) Further Evaluation required in NAVY shipboard applications for Survivability.
2) NAVY needs to identify requirements.
3) Assorted Footprints: Require a more durable sealer that conforms to anticipated protrusions in shipboard decks and bulkheads after damage from weapons hit/ explosions.
4) Extend length of strongbacks to cover width of NAVY W.T.Doors, Hatches, 32.
5) Design shoring strongback 7ft. length to hold weight of 12,000 LBS. Consult current design specifications for 7 and 12 length telescopic steel shores.
6) Retain the 6 magnets with 1250 LB. holding capability.
7) Add 4 magnets with a 2500 LB. holding capability.
8) Add 20 magnets with a 250 LB. holding capability for Shipboard Collective Protection System Integrity. Superstructure bulkhead/deck Patch Sealing System designed to maintain 2 inches water gage pressure. To be added to CPS Repair Kits.
9) Develop a canvas Tool Kit to stow and transport the equipment. Insure protective pads cover magnets to prevent inadvertent attachment to metal structure when transgressing tight openings; such as watertight scuttles.
10) Develop Pipe Patching application for fuel, fire-main, L.P. and H.P.air and chilled water systems utilizing QF-2 with fire proof strap assemblies / quick snap holding buckles with flexible foot prints for 4 through 10 piping. Capability of installing in 30 seconds or less.
11) Review design and need for a portable pad eye application using the 2500 LB. magnet.
12) Review applications, quantity and deployment of assets.
