Summary of Trips

Two trips were made during the fiscal months of October & November, 1993. On November 1, the Rowan Crew Quarters were sunk at the Rigs to Reef Site FH-7. On November 11, a load of concrete rubble from the old Sears Town Shopping Center was deposited at the Ship Island Shallow Rubble Site FH-11.

Rowan Reef FH-7

Rowan had an old set of Crew Quarters replaced on an oil derrick which they needed to dispose of. The markings indicated it was stationed in Juneau, Alaska. They were referred to MGFB by the BMR. The FH-7 site was offered as a disposal site for this large structure which is approximately 120 feet long X 35 feet wide X 35 feet high. The material was placed on the bottom on November 1 at about 11 A.M. despite high winds and seas. Rowan had three Tug boats, a Jack-Up rig and a significant crew of men working on the project which went very smooth and professionally. The material was hoisted off the barge after being cut loose with torches. The barge was towed out of the way and the material was lowered to its resting place. A diver was sent down to cut the hoisting cables loose. The material was initially targeted to land at LORAN Coordinates 12536.0, 46921.0. High winds and seas hampered set up of the equipment which was moved northward to ensure staying within the boundaries. The final resting place is at LORAN Coordinates 12536.8, 46922.1, 29587.2-.3. The surrounding depth was 128 feet with 92 feet of clearance measured over the top of the structure.

The Ship Island Shallow Rubble Site FH-11

On November 11, a load of concrete from the old Sears Town Shopping Center in Pascagoula was carried out by Colle Towing to the FH-11 Site inside Ship Island. The material was deposited in an area of about 200 feet square, centered at LORAN Coordinates 12226.0, 47081.0, and 29447.3 The area was marked with a lighted flashing buoy which was deposited close to the center of the site at coordinates 12226.1, 47081.0, and 29447.4. The light flashes at a rate of 15 flashes per minute. The depth was 18.3 feet with a least depth reading of 15.1 feet.
