Seascour In Action

---

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.

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
