BARGE INSPECTION

REPORT NO. 5793 JUNE 29, 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 21st and 29th days of June 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.

DESCRIPTION

The steel barge is called “Baltimore”. The barge is a hopper/utility barge with fore and aft rakes.

The barge was built in the year 1990. The barge’s approximate measurements are as following:

LOA 60’0”, BEAM 24’0”, FROM WATERLINE TO DECK GUNWALE 4’4”, and DRAFT 2’0”.

The transverse trusses are 2” x 3” x .250” placed at 24” centers. The vertical stanchions are 3” x

5” x .250” channel. The diagonal stanchions are 2” x 2” x .250” channel. The bottom frames are

2” x 3” x .250” placed at 24” centers. The barge has soft chines. The 5/16” (.3125”) steel plates were used in the construction of the deck, hull sides and bottom. A standard of 20% metal loss is being used with ultrasound gauge error of 0.025. Any readings lower than .250” is below acceptable level.

PORT HULL SIDE - EXTERIOR

This area starts at the bow from the water line to the bottom of the vessel. I noted that on port side the weld seams have heavy stay current and significant metal loss.

PORT HULL SIDE – EXTERIOR (cont.)

There is a stainless steel washer with bolt that was used to stop a leak as shown on the left side picture. The right side picture shows very deep crevice pitting and significant metal loss. A reading of .292” was taken beside the pitted areas at the two foot mark. Note, that in the left side picture there are two ultra sound readings: one is .117” and the other is .118”, which indicates a very thin area of metal. This reading was taken at the four foot mark.

The picture on the left shows the degree of metal loss from stray current. The picture on the right shows the amount of exterior scaling.

FORWARD RAKE EXTERIOR

The rub rail on the starboard side is pushed inward as shown on the picture below.

The forward rake was covers with a thick layer of barnacles. The barnacles were removed in several areas for inspection. The weld seams that are eaten away by stray current, pitting ,and some scaling. Note: a review of the original report, which was dated May 2018, shows heavy pitting. At the time of the previous report, the hull was sand blasted.

There is a bolt and washer repair as shown on the right side picture.

The ultra sound reading on the left side picture shows a fair reading of .324”. The reading on the starboard side was .305”.

Marine Surveyor June 29, 2022

INSPECTION REPORT #5793 PAGE 12 of 31

AFT RAKE EXTERIOR

The tabs that support the chaffing gear for the bow insert are in very poor condition and will be to be replaced.

There was a fair amount of pitting on the transom below the water line. Also, there are rust blooms above the water line.

There also was a fair amount of marine growth on the transom.

The cut out readings were . 317” port side, .310” center, and .312” starboard side. These readings were found to be satisfactory. However, there was still the rust blooms and pitting.

Marine Surveyor June 29, 2022

INSPECTION REPORT #5793 PAGE 13 of 31

BOTTOM EXTERIOR

Bottom was heavily coated with barnacles. Several areas were randomly scraped for inspection.

Noted loss of bottom paint along with rusting of the bottom. The interior was ultra sounded for a better idea of the overall condition of the bottom.

DECK

The deck appears to be in satisfactory condition with light rusting and some oil canning of the deck. The deck has very little paint protection. Radom ultra sound reading taken the bow is .319” six feet in from the starboard side. Going back from the bow sixteen feet and four feet in from the coming .314”. On the starboard side sixteen feet aft of the bow and five feet from the coaming, there is a reading of .296”.

The catwalks were found to be in good condition.

Marine Surveyor June 29, 2022

INSPECTION REPORT #5793 PAGE 14 of 31

SPUDS: Noted on deck there are two steel spuds: one is 25’ long and one has the end cut off and measures 21’ 9”. The lower end was cut off.

The 25’ spud forward end wing is bent. The mounting holes are corroded and in poor condition.

Both units are rusted with no protective coatings.

The spud tubes have some light rusting and scaling at the base. The weld appears to be in good order.

MANHOLES: four manholes: two on each side located outboard of the coaming. There are four

Barier aluminum flush mount hatches. The hatch seals were replaced at the time of my inspection.

INSPECTION REPORT #5793 PAGE 16 of 31

COAMING: steel coaming with cap and 25 vertical support. The forward end of the coaming is open. The forward section on both port and starboard sides is rusted at the bottom. The coaming cap is distorted and damaged.

DECK HARDWARE

Twenty-four inch kevel cleats and two horn bitts, which are well secured with no defects noted.

Marine Surveyor June 29, 2022

INSPECTION REPORT #5793 PAGE 17 of 31

WINCHES: the vessel is equipped with two Pull Master hydraulic winches. Serial number on the aft winch is 92125; the forward winch ID plate is missing. The winches are well secured. The cables are in poor condition. The winches were not tested for operation.

INTERIOR COMPARTMENT #1 - FORWARD RAKE

The steel framing in compartment #1 is in good condition. The bottom frames and side frames and the first 12” of the vertical stanchions are heavily rusted.

The underside of the deck and upper portion of the framing still holds most of its protective coating.

The bottom has standing water and sludge. Due to buildup of biologic marine growth on the exterior bottom and standing water and sludge in the interior of compartment, ultrasounds were taken where accessible from the interior. The bottom frames make a 2’x 4” grid. All readings were taken close to center creating a 2’x 4’ grid pattern. From a visual inspection and ultrasound reading, there is no need for steel replacement in compartment #1. However, located at Bay #4 frame #4 is a reading of .280”. This reading is .005” below the normal metal loss. Compartment

#1 will need to be pumped dry, all steel cleaned, and new protective coating applied to all surfaces.

INTERIOR COMPARTMENT #4 - AFT RAKE

The steel framing in compartment #4 is in good condition. The bottom frames, side frames, and the first 16” of the vertical stanchions are lightly rusted. The bottom has standing water and sludge. The underside of the deck and upper portion of the frames still holds most of its protective coating.

Due to buildup of biologic marine growth on the exterior bottom and standing water and sludge in the interior of compartment, ultrasounds were taken where accessible from the interior. The bottom frames make a 2’x 4” grid all readings were taken close to center creating a 2’x 4’ grid pattern. From a visual inspection and ultrasound readings, there is no need for steel replacement in compartment #4. However, located at Bay #9 frame #2, there is a reading of .275”. This reading is

.010 below the normal metal loss. Compartment #4 will need to be pumped dry all steel cleaned and new protective coating applied to all surfaces.

RECOMMENDATIONS

1) Replace steel from the lower rub rail to the chine of the forward rake, aft rake, port hull side, and starboard hull side.

2) Repair the starboard lower rub rail. This repair can be done in section versus replacing the entire rub rail.

3) The rust bloom areas above the water line can be replaced in section versus replacing the entire area.

4) Since the exterior of the barge had limited access due to the barge setting on the railway cart and covered with barnacles, an evaluation of the bottom was taken by interior ultra-soundings.

It would appear that not all of the bottom will need to be removed. However, there are sections that will need to be cut away for steel replacement. I recommend the following:

a) Clean the interior bottom of all mud, concrete and debris.

b) Sand blast the barnacles off the bottom.

c) Areas of steel plate that have heavy scaling and heavy pitting will need to be replaced.

d) Proper coating (epoxy) should be applied to interior after plate replacement

5) As per ultrasound readings, the following areas will need replaced. The areas are given by interior locations:

SURVEYOR’S COMMENTS

Overall, there is minimal loss of steel for this barge. The problem is stray current issues, which have caused a problem for structural integrity. From the natural waterline down to the chines, including both rakes, there is an excessive amount of stray current damage. I have also noted that while underload, there are rust blooms that formed above the waterline on the aft rake. On the starboard side lower rub rail, there is a considerable amount of stray current to the underside of the rub rail.

The deck shows normal wear and tear for a barge of its age, with some rusting with very little paint protection remaining. There is oil canning throughout the deck. The coaming is well secured and does have some minor damage, but it is still usable.

The bottom was covered with barnacles, which could not be removed at the time inspection since the barge was inspected on the rail cart, which allowed very limited access. In order to get an idea of the condition of the bottom, the bottom had to be ultrasounded in the interior.
