Subsea Cleaning
Subsea Cleaning machines allows us to clear out marine growth in a variety of surfaces including ship hulls and man-made lake bed.
Subsea Cleaning
What is Subsea Cleaning?
Subsea cleaning refers to the process of cleaning underwater structures and equipment. It is necessary in industries such as offshore oil and gas, marine transportation, and underwater infrastructure maintenance. Subsea cleaning helps remove marine growth, sediments, corrosion, and other contaminants that can negatively impact the performance and integrity of underwater assets.
Applications
Applications for Subsea Cleaning
Offshore oil and gas industry:
Subsea cleaning is vital in the oil and gas sector for maintaining underwater equipment, pipelines, and platforms. It helps remove marine growth, sediments, and corrosion to ensure the efficient operation of production systems and the integrity of subsea infrastructure.
Marine transportation and shipping:
Water jetting is used for cleaning ship hulls, propellers, and other submerged parts to reduce drag, increase fuel efficiency, and prevent the spread of invasive species.
Underwater infrastructure maintenance:
Subsea cleaning is required for the maintenance of underwater infrastructure, including bridges, tunnels, ports, and piers. It helps remove marine growth and sediment buildup, ensuring structural integrity and preventing damage.
Water Jetting Machines
Water Jetting Machines for Subsea Cleaning
Water jetting is widely used in the ship repair & marine industries. 300bar is used to remove marine growth & salt deposits prior to grit blasting. Larger pumps can be specified to allow multiple jetting guns to be used simultaneously. 700-1000bar will remove loose coatings & corrosion, leaving sound coatings intact, ready for repainting if total coating removal is not required. It is often said that if 1000bar does not remove the coating then it is sound enough to paint over. 2750bar (UHP) will remove all coatings & corrosion back to white metal. Marine paint manufacturers have developed paints to apply to hydro-blasted surfaces & actively promote this method as it removes all chlorides & provides the best possible surface for recoating.
Benefits
Benefits of Water Jetting
Dust free allowing other trades to work in the vicinity.
- Minimal waste disposal, 98% less than grit blasting.
- Environmentally friendly.
- No containment of sensitive rotating equipment.
- Removes all chlorides from substrate leaving a perfect surface for new paint.
- Unlike grit blasting does not profile steel so does not trap chloride contaminants in the substrate.
- Minimal water consumption, most of which evaporates when using UHP.
- Reduces time during dry-docking.
- Sheeting not required.
- Can be used in wet & windy conditions.
- The pump is versatile & can be used for other cleaning & cutting applications.
