BARGE INSPECTION

REPORT NO. 5792 JULY 8, 2022

TO WHOM IT MAY CONCERN: This is to certify that the undersigned surveyor at the request of Kelly Wright, State of Maryland, Department of Natural Resources, Engineering and

Construction Division, 580 Taylor Avenue, D-3, Annapolis, Maryland, 21401, attended the barge out of the water at DNR E/C Terminal, 301 Cemetery Avenue, Cambridge, Maryland, 21613, on the 8th day of July in the year 2022, and did an inspection of the deck, hull sides, bottom, and interior to determine overall condition and establish areas of repair. As per contract, the barge was inspected for structural integrity. All accessible compartments were inspected for structural defects. Random ultrasonic readings were taken.

DESCRIPTION

The barge is a spud barge referred to as “CAMBRIDGE.” The approximate measurements are:

LOA 80’0”, BEAM 26’0”, and DEPTH 5’0”. The barge consists of 6 compartments. The barge was manufactured by Yacht Maintenance Company, in the year 1985.

EQUIPMENT AND PROCEDURE

The inspection was conducted using a Cygnus 1 heavy duty multiple echo ultrasonic thickness gauge and Check Line Wall thickness gauge TI-CMX calibrated for steel.

FORWARD RAKE EXTERIOR

The forward rake has a considerable amount of heavy pitting on the head log. However, the readings for the steel thickness were found to be satisfactory.

There is pitting on the rake, which is hard to see from the pictures. The upper rub rail is dinged up, but still in usable condition.

INSPECTION REPORT #5792 PAGE 3 of 26

PORT SIDE EXTERIOR

Since the hull side below the water line was not pitted, random readings were taken at 10 foot intervals. I did note some light pitting above the water line and minor crevice pitting on the hull side. However, it is not a structural issue. For the ultrasound reading, .370” was used as a base line. The readings are:

INSPECTION REPORT #5792 PAGE 7 of 26

AFT RAKE EXTERIOR

The aft rake has very heavy pitting, mostly on the port side. A test reading was .375”. At the bow cutout, the fender supports are heavily rusted and scaling. There are rusted areas forward of the fenders.

The rake appears to be in satisfactory condition with no damages noted at the time of my inpsection.

DECK

The deck has oil canning, and most of the paint has been worn away. On the forward end of the barge, about 10 feet aft, the deck is torn open for about 10 inches, as shown in the picture below.

I also noted very heavy pitting on the port forward corner around the forward section of the coaming, as shown in the below picture on the left.

The picture on the right show heavy paint loss with a considerable amount of surface scaling.

Since the deck was so rough, interior readings were taken to determine metal loss.

On the aft deck, from the coaming base, running approximately 4 feet aft, the deck is very heavily scaled. See pictures below.

DECK HARDWARE (cont.)

The steel coaming is open in the front end of the barge. The coaming was poorly supported, and is twisted and distorted. The coaming is also rusted out on the bottom on both sides and aft section.

There are two hydraulic Pull Master winches. Cable and hydraulic hoses appear to be in satisfactory condition. Operation was not tested.

There are two I beam spuds install in the aft spud wells. The spud well flanges have heavy corrosion around the bases.

INTERIOR

The side frames, deck frames, and bottom frames are 3” x 4”. The longitudinal trusses are 2” x 6” channel with 2” x 3” angle iron for the diagonals.

COMPARTMENT #1 FORWARD RAKE

The steel framing and bulkhead in compartment #1 are in good condition. The bottom frames and side frames, and the first 10” of the vertical stanchions are heavily rusted. The bottom has standing water. The underside of the deck and upper portion of the frames still holds its protective coating. The standing water needs to be removed, the areas of rust will need to be cleaned, and new protective coating applied to clean areas.

COMPARTMENT #2 INTERIOR

Compartment #2 is in good condition. The bulkhead is in good condition. The steel framing and plating still holds its protective coating. Note, there are areas throughout with light rust starting to form. There was no significant metal loss detected to the steel framing. However, both longitudinal trusses are heavily distorted. Due to the distortion, ultrasound readings were taken using a 2’ x 4’ pattern. The bottom appears to be in good condition from the ultrasound readings.

The deck was ultrasound using the same 2’ x 4’ pattern. Each area of replacement is 2’ x 4’. The areas of rust will need to be cleaned, and new protective coating applied to clean areas. The two longitudinal trusses are 16’ long and are constructed from 2” x 6” channel and 2” x 3” angle iron.

It’s recommended that vertical stanchion be added to the new trusses.

COMPARTMENT #5 INTERIOR

Compartment #5 is in fair condition. The bottom plating and the first 12” of the steel framing are losing its protective coating and showing signs of heavy rusting. There was no significant metal loss detected to the steel framing. However, the forward bulkhead framing is showing signs of rust damage. Due to the condition of compartment #5, ultrasound readings were not needed at time of inspection. The standing water needs to be removed, the areas of rust will need to be cleaned, and new protective coating applied to clean areas. It is recommended that the vertical stanchion be added to the trusses.

8) Repair the two small holes in the head log on the aft rake.

9) Replace the steel supports for the bow fenders at the aft rake.

10) Replace the zincs ( if not already completed)

11) Run an overlay around the spud tubes to make up for the metal loss from the corrosion.

12) Remove the water, rust and dirt from the interior. Prime and paint the rusted areas.

13) In compartment #2, replace bent longitudinal trusses. Also, replace all the bent angle iron diagonals in compartment #2.

14) Replace the bent diagonals in compartment #3.

15) In compartment #4, the weld on the deck frame #5 on the starboard side needs well repaired.

16) Clean the rust from the exterior, prime, and paint.

17) Repair the dented rub rails and corners, if so desired.

SURVEYOR’S COMMENTS

At the time of my inspection, there was still a few zincs remaining on the hull sides; thus, we did not see a lot of pitting of the hull.

I had a few concerns on the construction, such as the coaming was not properly supported on the sides. Also, drainage seemed to be a problem with a lack of properly placed limber holes.

The other concern I had was the light construction of the interior supports. It is my professional opinion that there should be more vertical stanchions and perhaps heavier transverse trusses.

The forward manhole cover is made of aluminum. Since the hatch is install on the forward end of the barge, it may be subjected to weight, which the hatch is not designed to handle. Since the ring needs replaced and deck area will also need to be replaced, it may be a good idea to relocate the hatch.

It would appear that a lot of the problem with said barge was lack of protective coatings and water in the interior.
