Hydro Blasting & Underwater Hull Cleaning
Hydro Blasting & Underwater Hull Cleaning UAE
Our professional divers and certified technicians provide safe and efficient hydro blasting, underwater hull maintenance, and under water inspection for cargo ships and tankers across Sharjah and UAE ports. By removing fouling and restoring hull surfaces, we help shipowners maintain vessel efficiency, reduce drag, and extend coating life—all without the need for dry docking. Astern Marine ensures IMO-compliant operations with advanced tools and expert supervision for reliable, high-quality results.
High-Pressure Hydro Blasting
Hydroblasting uses high-pressure water jets to remove rust, old coatings, and marine growth from steel surfaces. Astern Marine operates advanced UHP (Ultra High Pressure) equipment, ensuring fast surface preparation for repainting or inspection. This method avoids chemical residues, minimizes downtime, and is fully compliant with MARPOL environmental standards.
Underwater Hull Cleaning & Propeller Polishing
Our professional diving crews deliver full underwater hull cleaning, including propeller polishing, rudder maintenance, and sea chest inspection.
Using approved underwater brushes and vacuum systems, we remove biofouling safely and improve vessel hydrodynamics — reducing fuel consumption and CO₂ emissions.
Underwater Inspection
Our professional divers carry out detailed underwater inspection services to assess the vessel’s hull, propeller, rudder, and sea chests. They use high-resolution cameras and lighting systems to record clear visuals, even in low visibility. Moreover, each inspection helps detect early damage, corrosion, or fouling before it becomes costly. As a result, shipowners can plan maintenance on time, prevent unexpected repairs, and ensure safe and efficient operations across UAE ports.
Safety & Compliance in Underwater and Hull Maintenance
Astern Marine follows IMCA, ADCI, and STCW diving standards to ensure complete operational safety during all hull cleaning and hydro blasting works. Each operation includes pre-dive risk assessments, real-time supervision, and post-cleaning video reports.
All waste residues are safely collected and disposed of under UAE port authority and MARPOL Annex V requirements.

Frequently Asked Questions (FAQ)
Q1. What is hydro blasting in ship maintenance?
Hydro blasting is a high-pressure water technique used to remove rust, paint, and marine growth from a vessel’s surface. It provides a smooth, paint-ready finish without chemicals—making it safe, fast, and environmentally responsible.
Q2. Why is underwater hull maintenance important?
Underwater hull maintenance removes marine fouling like algae and barnacles that increase drag. Regular upkeep helps vessels save fuel, maintain optimal speed, and reduce emissions while meeting IMO efficiency standards.
Q3. Where does Astern Marine operate in the UAE?
Our teams work across major UAE ports, including Sharjah, Fujairah, and Khorfakkan. Certified divers and hydroblasting technicians are available for rapid deployment and reliable vessel support.
Q4. Are your hydroblasting operations IMO and MARPOL compliant?
Yes. All procedures follow IMO and MARPOL environmental guidelines. Waste residues and fouling are handled responsibly and disposed of via approved marine facilities to ensure full compliance.
Q5. Do vessels need dry-docking for hull or propeller work?
No. Most hull and propeller maintenance can be performed underwater while the vessel is afloat, reducing dry-docking costs, downtime, and enabling faster cargo operations.
Q6. Can hydroblasting be applied to tanks or holds?
While the method can technically treat tanks or holds, Astern Marine uses dedicated tank systems for these areas to maintain specialized compliance and avoid overlapping services.
