Tank Cleaning

Grey Water & Black Water Tank Cleaning

We suggest cleaning your grey water and black water tanks once per year. This allows for early detection and repair of tank coating failures and corrosion. This will also help you avoid potential costly repairs in the future if left untreated. If coating repairs are not detected early and repaired, more invasive tank cleaning processes, like tank abrasive blasting and hot work repairs, may be required. Annual cleaning will also ensure the tanks are maintained and you have no surprises for your next 5-year Lloyds Survey or 5-year ABS Survey.

Regular cleaning of grey water and black water tanks also keeps them from becoming clogged with solids, like soap scum and sewage sludge, which can block pipe penetrations and discharge pickups. Clogged grey and black water tank pipes can wreak havoc with foul smells and backed up drains or heads, which is not good for crew living on board or charter guests. These tank and pipe issues may lead to extensive engineering and cleaning services to open tank lids and break open sewage piping in the middle of a charter, which may negatively affect your charter gratuity.

Fresh Water Tank Cleaning, Sanitizing & Chlorination

Fresh Water and Potable Water tank cleaning is an essential, annual maintenance step for any yacht. In this process, our crew first pressure washes the tank interiors with hot water to remove potential contaminants including bacterial growth, legionella, and sediment. All wash water and debris is pumped out before we move on to the sanitizing and chlorination process.

This process will keep your crew and guests healthy by removing harmful build up of bacteria that can cause health complications including Legionnaires disease, which can occur not just from drinking water, but from inhaling airborne bacteria such as in the shower. Trust the experts at Coastal Tank to thoroughly clean your fresh water and potable water tanks to keep you healthy and safe.

Our Yacht Tank Cleaning Process

Our crew is made up of professional and experienced individuals who prioritize cleanliness and professionalism at every yacht tank cleaning job. We adhere to the following yacht tank cleaning process:

1. First, our crew conducts a walk-through inspection with you to determine the most efficient and practical path for the hose runs before we start laying down clean drop cloths for protection. We will complete any onboard confined space entry procedures with your vessel’s point of contact.

2. Our technician will suit up with all the required PPE. This system provides us with OSHA approved Grade D breathing air which is required for IDLH environments. This system consists of a dedicated electric breathing air compressor, four stage filtration with carbon monoxide monitor, dedicated breathing air lines, and full face mask with pressure demand regulator. We will always have a safety hole watch while the technician is in the tank. We use high-powered vacuum hoses and high-pressure cleaning hoses to completely remove all contaminants, sediment, and build up from your yacht tanks. The technician will pump out the residual tank contents into our state of the art 4,000 gallon vacuum tank truck, which has the ability to pump waste and wash water up to 1,000 feet away from where the truck is staged. The vacuum system utilized on the truck is an enclosed self lubricated system. This will ensure that no annoying smoke will be in the vicinity during pump outs or tank cleaning, unlike older vacuum pumps that burn oil and exhaust smoke to stay cool. We utilize both truck mounted and mobile high pressure steam cleaning units depending on the job setup.

3. Next, our technician will begin to pressure clean the tank with hot water, chamber by chamber. We select the best cleaning chemical or sanitizer based on each tank application. Our technician will adjust the cleaning pressure as needed to remove contaminants from the tank interior. During the cleaning process, any coating failures that have loose flaking paint will also be removed and chased back to good adhering paint. The tank will remain under constant vacuum from our vacuum trucks while the tank is being cleaned.

4. Once the tank is completely washed, the cleaning technician will vacuum the tank dry in preparation for inspection.

5. Once the cleaning is completed, the foreman of the job will inspect the tank interior for any abnormalities, structural damage or tank coating failures. Any issues found will be photo documented and immediately brought to the attention of the chief engineer and captain. Our crew will discuss a repair solution with you for anything noted. Tank inspection reports with photos and findings are available upon request for an additional fee.
