Abrasive Blasting
Sandblasting Specifications
We understand that each vessel has unique needs when it comes to surface preparation and maintenance. That’s why we offer a range of specialized sandblasting services, meticulously tailored to ensure the best results for every ship. Our sandblasting techniques are designed to address different levels of surface degradation, ensuring that each vessel is treated with the precise care it requires.
Our Sand Sweeping at S.A 1.0 is a light blast cleaning process that effectively removes surface contaminants from the hull of the vessel, from the waterline to the keel. This service focuses on eliminating surface rust, loose paint, and other minor impurities, particularly in corroded areas and beveled edges. It’s an ideal option for vessels requiring a quick yet effective cleaning, ensuring that the surface is adequately prepared for the next maintenance step without extensive material removal.
For vessels needing more intensive preparation, our Sand Sweeping at S.A 2.5 delivers near-white blast cleaning. This process goes deeper, thoroughly removing rust, old paint, and other stubborn contaminants from the hull, including all corroded areas and beveled edges. The near-white finish provides an optimal surface for the application of new coatings, ensuring maximum adhesion and longevity of the protective layers, which is crucial for vessels facing harsh marine environments.
Our Commercial Blast Cleaning at S.A 2.0 offers a more robust cleaning solution, designed to address more significant levels of corrosion, scale, and contaminants on the vessel’s hull. This level of blasting is particularly suited for vessels that have been at sea for extended periods, where environmental exposure has led to more substantial surface degradation. The thorough cleaning achieved with S.A 2.0 ensures that the hull is fully prepared for further restoration or protective treatments.
When absolute precision is required, our Near-White Blast Cleaning at S.A 2.5 is the solution. This intense blasting process strips the hull down to near-white metal, leaving only the most minimal traces of discoloration. This level of surface preparation is essential for vessels that will undergo critical coating applications or require high-performance finishes. By ensuring an almost completely bare metal surface, we guarantee that new coatings will adhere flawlessly, offering superior protection and durability.

Exceeding Industry Standards
Our sandblasting services are engineered to exceed industry standards, ensuring that every vessel we service is prepared to withstand the most demanding conditions. We pride ourselves on delivering exceptional quality and reliability, making sure your vessel is not just maintained but enhanced, ready to face any challenges that lie ahead
Abrasive blasting plays a crucial role in achieving these goals, and its application in our shipyard can be described as follows:
Surface Preparation
A ship’s hull is its shield against the relentless forces of the ocean. Before any new coating or paint can be applied, it is crucial to remove old paint, rust, and other contaminants. Our abrasive blasting services strip away these impurities, leaving a clean, roughened surface that promotes superior adhesion for new coatings. This process not only enhances the durability of the paint but also extends the life of the vessel, ensuring it remains seaworthy and visually impressive.
Dry-Docking
When a ship enters dry-dock, it’s the perfect opportunity for a comprehensive overhaul. Our dry-docking services include extensive abrasive blasting, targeting hull damages, fouling, and corrosion that have accumulated over time. By addressing these issues, we restore the vessel’s integrity and appearance, ensuring it is ready to tackle new voyages with renewed strength and efficiency.
Tank Cleaning
The tanks within a ship, such as fuel tanks, ballast tanks, and cargo holds, play vital roles in its operation. Over time, these tanks can accumulate scale, residues, and old coatings that hinder their functionality. Our abrasive blasting services thoroughly clean these tanks, removing all unwanted materials and preparing them for continued use. This process is essential for maintaining the efficiency and safety of the ship’s operations.
Removal of Marine Growth
Marine growth, including barnacles and algae, can cling to a ship’s hull, increasing drag and reducing fuel efficiency. This growth can also negatively impact the vessel’s performance and lifespan. Through abrasive blasting, we effectively remove marine growth, restoring the hull’s smooth surface and optimizing the vessel’s performance. This service not only enhances the ship’s speed and fuel efficiency but also contributes to its overall longevity.
Corrosion Control
The harsh marine environment is a constant threat to a ship’s metal surfaces, leading to corrosion that can weaken the vessel’s structure. Abrasive blasting is a critical step in combating this issue. By removing existing corrosion and preparing the surface for corrosion-resistant coatings, we protect the ship from further deterioration. This proactive approach is essential for preserving the vessel’s strength and safety over time.
Repairs and Restoration
When a ship sustains damage, such as hull breaches or structural issues, it’s crucial to start with a clean, contaminant-free surface before making repairs. Our abrasive blasting services ensure that the affected areas are thoroughly cleaned, allowing for secure and effective repairs. This process not only restores the ship’s integrity but also ensures that the repairs will last, keeping the vessel in prime condition for years to come.
Paint Removal and Refinishing
Regular repainting is essential for maintaining a ship’s appearance and protecting its surfaces from the elements. Our abrasive blasting services efficiently remove old paint and coatings, creating the ideal surface for a fresh application. This process ensures that the new paint adheres properly and lasts longer, providing both aesthetic appeal and functional protection.
Safety Measures
At Guyana Port Inc., safety is our top priority. Our personnel follow strict safety protocols during abrasive blasting operations, utilizing proper ventilation and dust collection systems to control dust and airborne particles. We ensure that our operators are equipped with the necessary personal protective equipment (PPE) to safeguard them from potential hazards, creating a safe and secure working environment.
