Test #01-003, Seapatch/QuickFrame Flooding Control Evaluation While Wearing Wet Suit in Partial Water Immersion

DAMAGE CONTROL ENGINEERING TEST FACILITY

(DCETF)
NAVAL RESERVE CENTER, BALTIMORE
TEST DATA

TEST NUMBER: 01-003 DATE: 03/13/01
TEST TITLE: Seapatch/QuickFrame Flooding Control Evaluation while wearing wet suit in partial water immersion. See Photo of Seapatch Kit
RESULTS:

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 3”dia. 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

RECOMMENDATIONS:

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.

DESCRIPTION OF TEST: Seapatch 6 is a combination of 6 magnetic attachment assemblies / patch-QuickFrame (QF-2, QF-3 devices that have several application versions. Seapatch devices are designed to seal any type of leak, large or small circular punctures, jagged tears, rips and cracks to stress fractures and weld fatigue failures. They can be applied to curved-radius or flat surfaces as well as right angle corner joints, above or below the waterline, interior or exterior. Further evaluation will determine their suitability for watertight scuttles, hatches and doors. Equipment stored in a 21” x 32”x 11” Diamond Plate Aluminum Case. Material fabrication tightening and cam- off devices, 316L stainless steel, connectors and strongbacks, Powdered coated aluminum and carbon steel. Weight: 165Lbs.
EVALUATION OBJECTIVES:
1) Determine the suitability and effectiveness of the Seapatch hull patching/sealing device assemblies (utilizing 6 magnetic hull attachments) with two man teams to stop or control flooding to an acceptable rate.
2) Determine the Seapatch systems effectiveness to secure leaks in warped doors, hatches and scuttles.
3) Determine the effectiveness of the 1250 LB.holding power magnets to serve as Anchor points during shoring evolutions.
4) Develop list of other shipboard applications.
