Comprehensive Underwater Inspection Services
Our underwater inspection services are approved by all major classification societies, ensuring the highest standards of safety and compliance. Additionally, we offer a range of advanced inspection methods designed to meet your vessel’s specific needs. These methods include CCTV inspections with high-definition digital recordings, photographic inspections using state-of-the-art digital cameras, and close visual inspections conducted by skilled divers. By using these techniques, we provide a thorough evaluation of your vessel’s underwater condition, allowing for proactive maintenance and repairs.
Types of Underwater Inspections
We offer several types of underwater inspections, each carefully designed to meet different requirements. These inspections are crucial because they help detect potential issues early, which can ultimately help avoid costly repairs and downtime.
In-Water Surveys and Inspections: Our in-water surveys provide a detailed assessment of your vessel’s overall condition. After the inspection, we supply a comprehensive technical report and a DVD documenting all findings. Consequently, you will have a reliable record for future reference, ensuring peace of mind.
Underwater Surveys for Class Extensions: We conduct underwater surveys to ensure your vessel meets all necessary regulatory requirements for class extension. By performing these inspections, we help maintain your vessel’s certification, thereby allowing uninterrupted operation and compliance with all safety standards.
Fouling Conditions: Fouling buildup on the hull can significantly reduce fuel efficiency and vessel performance. By detecting fouling early, we enable you to take corrective action promptly. As a result, you can maintain optimal performance, avoiding potential long-term operational issues.
Close Visual Weld Inspections: Our experienced divers carry out detailed visual inspections of welds to identify any structural problems. Detecting these issues early can prevent costly repairs and maintain your vessel’s structural integrity.
Pre-Purchase Surveys: If you are considering purchasing a vessel, our pre-purchase inspection offers a comprehensive evaluation of its underwater condition. This service ensures that you make an informed decision and helps you avoid any hidden issues that could arise post-purchase.

Hull Coatings and Damage Inspections: We inspect the hull coatings to assess any damage that may affect your vessel’s performance. Timely identification of coating damage allows us to take corrective measures and protect your vessel from further deterioration, ensuring its longevity.
Rudder and Propeller Inspections: Regular inspections of the rudder and propeller are essential to maintaining maneuverability and operational efficiency. By detecting any wear or damage early, we can help ensure your vessel’s performance remains optimal, reducing the risk of operational failures.
Non-Destructive Testing (NDT) Services
In addition to traditional inspections, we offer advanced Non-Destructive Testing (NDT) services, which allow us to detect hidden issues without causing damage to your vessel. These methods are essential for identifying potential problems before they escalate, ensuring the continued safety and reliability of your vessel. Our NDT services include:
- ACFM or M.P.I. (Magnetic Particle Inspection)
- Eddy Current Testing
- Plating Thickness Measurements
- Cathodic Protection Measurements
By employing these techniques, we help you gain valuable insights into the condition of critical vessel components. As a result, you can make informed decisions about maintenance and prevent costly repairs.
