Underwater Dock Light Maintenance

Dock Lights add a lot of beauty to a dock. The colors, the atmosphere, the views.

Dock Lights add a lot of beauty to a dock. The colors, the atmosphere, the views.

Unfortunately, there is always marine growth on these lights. Barnacles, mussels, oysters, and more love to attach and grow on these lights.

There are many materials in a dock light. Various metals, poly coatings, glass and more.

Your typical inorganic scale remover cannot be used on dock lights as they destroy the dock light, especially the glass.

Dock Light Before Cleaning

As you can see there is tremendous marine growth on all parts of the dock light.

The owner of the light was looking at replacing the light. We told him to use Seascour to safely clean it.

The owner thought it would be a lot of work.

We showed him how simple and effective using Seascour could be.

We provided the owner of the dock light one gallon of Seascour and a bucket.

We told him to simply submerge the light in Seascour and allow it to soak. That was the procedure.

The owner put the dock light in Seascour in the morning just before he left for work.

He took the dock light out of the bucket, set it on his dock and sent us the picture.

The owner was beyond impressed.

Just before the descaling project was started, a new Tube heat exchanger was put in place.

The sprinkler system was run for 3 days. Seascour was sprayed on the tube bundle, ran down and exited the hull. Here it was directed to a tote. A pump drew Seascour out of the tote and sent it back up to the sprinkler system.

During this flush there was zero labor involved.

A few days later the project was complete, and the old and new tube bundles were inspected.

The new tube bundle is on the left; the original tube bundle is on the right. The client was very appreciative of this new, organic cleaning method and the vessel left dry dock 2 weeks early!

NAVSEA wanted a proof-of-concept trial test with Seascour on a 200-ton condenser that had titanium piping.

Traditional methods for cleaning these condesers is a combination of corrosive acids and mechanical cleaning. This is very time consuming and damages the condensers. Hydrochloric acid is typically used for this flushes gut causes Hydrogen Embrittlement for Titanium and this the wall piping. This can lead to a replacement of the condenser which could cost $1,000,000 dollars and months in port without deploying

Seascour is 100% organic, powerful and safe. Seascour is EPA Safer Choice Program certified for Outdoor Use.

USS MASON condenser before Seascour

Seascour working with an approved contractor hooked up a flushing system that had a pump, hoses, connections, filter and a reservoir. Approximately 62 gallons of Seascour was used.

USS MASON condenser after Seascour.

Seascour was flushed through the condenser system and then pumped out for inspection.

Discharge profile samples were taken and analyzed by an approved DOD laboratory.

The USN was amazed at the cleaning of the condenser, and they calculated that no more than 0.001mils of Titanium had been removed.

Case Studies

USCG Tug Boat- HVAC Heat Exchanger

At SeaScour, we are committed to producing the highest quality chemicals while ensuring the safety of our employees and the environment. Our state-of-the-art plant utilizes the latest technology to minimize waste and maximize efficiency.The system aboard the USCG Vessel 75305 consists of 1-sea strainer, 1-Heat Exchanger and approximately 30 feet of 1-1/2” diameter pipe. 


The ten-gallon tote had just two-gallons of Seascour added to the tote reservoir,  Seascour during the flush process would mix with the residual salt water with the system. This was calculated to have sufficient concentration to achieve a significant drop in pipe-line pressure. 

Actual Flush Program began at 09:54.


Initial pump pressure was 65psi. At 1100 pump pressure was 5-10psi. The system was re-aligned to allow overboard discharge. Initial pump pressure was 45psi but quickly dropped back to 5psi as the overboard discharge piping was also flushed. Seascour is the only Marine Scale Remover that can be discharged overboard.


Upon startup the USCG Tugboat Captain noted that the system was operating like new.

USCG Valiant - Refrigeration System Heat Exchangers

In cooperation with the USCG, Hendry Marine used Seascour to flush the heat exchangers and associated piping for the Refrigeration system and remove the scale buildup that prevented the system from operating.


6 gallons of Seascour were poured into the reservoir. The only modifications to the heat exchanger system were to disconnect a small section of piping and reverse the flow of one check valve. The entire setup took about 30 minutes. The pump was connected to the ships compressed air system and started.


Below is the operational log:

0954 – 

pump pressure 22psi

Inlet pressure 22psi

Outlet pressure 16psi

1039 – 

pump pressure 1psi

Inlet pressure 4psi

Outlet pressure <1psi


Between 1029 and 1124, the flush system was adjusted 3 times to flush some product overboard to clean the discharge piping. Third discharge – the crew was observing from topside and were highly impressed at all of the calcium discharged. Any previous descaling operations only involved the heat exchangers themselves; this was the first flush of the piping.

At this point the system was shut down but left in place to soak. At 1215 the system was disconnected and the crew reassembled the heat exchanger system.


At 1300 the refrigeration system was started and both heat exchangers were brought online. This was the first time both were used in 18 months.

The system discharging overboard – more of the discharge piping was descaled.


The operating system pressures – 

Inlet 3psi

Outlet 9psi

Typical system pressures were –

Inlet 12psi

Outlet 25 psi
