How to Keep Your Inland Marine Vessels on the Water Longer


One of the biggest expenses in the marine industry is lost income during annual mold remediation, regular reconditioning, and refurbishment. The total cost of these necessary services goes beyond that, of course, since reconditioning and refurbishing inland or marine vessels is incredibly expensive. But what if you could keep your vessels on the water longer between maintenance and lower the cost of those services altogether?

Maintenance on Inland and Marine Vessels Wastes Valuable Time

Marine and Inland vessels make money when they’re doing valuable work, and they lose money every day they’re not out on the water. So the possibility of keeping those boats and ships in commission longer probably really tugs at your purse strings. Traditionally, marine companies deal with regular maintenance in the same way:


Company A has 100 tugboats on the Chesapeake Bay. During 4 weeks every year, each boat is pulled in for reconditioning. On top of this expensive refurbishment, the company spends more than $10M on insulation and air conditioning units to lower the moisture levels and make the cabins more comfortable for the crew.


The problem with this situation is that the company is losing more than 16,000 work hours annually just dealing with refurbishment. And while this isn’t the most efficient or cost-effective way to deal with the issues of mold, moisture, and crew comfort, other choices just don’t seem to exist.

The Most Common Ways of Dealing with Moisture Don’t Work

Most often, marine companies have two ways of dealing with moisture on a marine vessel: either utilize insulation or use oversized air conditioners to remove moisture from the cabin of the ship. The problem is that neither of these help with the moisture in the air or the comfort of the cabin. Here’s why—lowering the air temperature doesn’t actually lower the amount of moisture in the air. In fact, cold air has higher Relative Humidity than warm air with the same volume of water.


On the other hand, adding insulation doesn’t help either because the moisture just gets into the walls and eventually creates new places for mold to grow. What ends up happening when you increase insulation and lower the temperature is that you end up creating a very damp and cold freezer for your crew to sit in while they’re out on the water.

How to Keep Your Inland and Marine Vessels on the Water Longer

While adding air conditioning and insulation seem like a good way to remove moisture from a marine vessel, they’re totally ineffective. But there is a way to lower humidity and raise the temperature of the cabins to save you money and keep your crew at a reasonable temperature when they’re at sea.

The key is to use a dehumidifier in conjunction with the existing HVAC system. By raising the temperature from 66-68 degrees to between 76 and 78 degrees, you maintain a comfortable and efficient temperature and allow a dehumidifier to manage the moisture content. Keeping the humidity of the ship at or below 55% RH, you may even be able to remove the expensive annual reconditioning altogether.
