Pre-Docking or Pre-Purchase Inspection

Pre-docking or pre-purchase inspections are crucial stages in the lifecycle of a vessel, ensuring its exploatation period, compliance with international regulations, and overall condition before docking or purchase. These inspections involve a general assessment of the vessel's structural integrity to identify any deficiencies or areas requiring maintenance or repair.

Hull Condition Program Assessment

A hull condition program assessment is a comprehensive evaluation conducted on the hull of a vessel to determine its overall condition, structural integrity, and maintenance needs. This assessment is crucial for ensuring the safety, seaworthiness, and operational efficiency of the vessel. During hull condition program ssessment, our experienced tehnicians conduct various inspections on ships hull, including: Coating Integrity, Thickness Mesurement, Corrosion Evaluation and Structural Integrity.

Steel Renewal Calculations and Drafts

Steel renewal calculations and drafts involve determining the extent of damage to steel structures on a vessel or any other maritime asset, calculating the required repairs or replacements, and creating detailed drafts or plans for executing the repairs. Based on the assessment, calculate the required repairs or renewals. This involves determining the amount of steel to be replaced, estimating material costs, and calculating labor and equipment expenses. We create detailed drafts or plans for executing the repairs or renewals. This includes preparing technical drawings, schematics, and specifications that outline the scope of work, repair methods, and materials to be used.

Repair Supervision

Steel repair supervision involves overseeing and managing the repair process of steel structures on vessels or maritime assets to ensure that the work is carried out safely, efficiently, and in accordance with industry standards and regulatory requirements. Our experts will ensure cost efficient supervision while also providing quality assessment before,during and after repairs.

Cathodic Protection Inspection

Cathodic Protection Inspection involves assessing the effectiveness and functionality of cathodic protection systems installed on maritime structures such as ships, offshore platforms, pipelines, and marine infrastructure. Cathodic protection is a vital corrosion prevention method used to protect submerged or buried metallic structures from corrosion by making them the cathode of an electrochemical cell. Visual assessment of the cathodic protection system components is to be carried out, including anodes, reference electrodes, cables, and electrical connections. Inspectors look for signs of physical damage, corrosion, or deterioration that may affect the system's performance.

ULTRASONIC THICKNESS MEASURING

Ultrasonic thickness measuring is a non-destructive testing technique used to determine the thickness of a material, typically metals, without causing damage to the material itself. This method relies on the principle of high-frequency ultrasonic sound waves. Backed by years of experience and a team of skilled technicians, we guarantee results you can rely on. We provide Non-Destructive Testing(NDT) Services that are related to following ultrasonic thickness measuring (UTM):

  • Surveys with final report preparation according to class requirements for UTM and Close-up,
  • Condition assessment programs (CAP/CAS),
  • Measurements per owner’s request,
  • Corrosion inspections,
  • Underwater ultrasonic thickness measuring.

Qualifications

IN-WATER THICKNESS MEASURING

Underwater ultrasonic thickness gauge can be used to measure  thickness of metal and many other solid materials, so this instrument is perfect for measuring thickness of remaining metal in ship hull structure and plating, while the vessel is still being in water. Our experienced diving team will provide a high level and low cost inspections while ensuring the integrity of the ship's materials and complying with the permitted limits of international standards for the thickness of the plates during their exposure to seawater. 

Equipment

The Cygnus DIVE is a wrist-mountable ultrasonic underwater thickness gauge that is providing an invaluable free hand while performing Ultrasonic Thickness Measurement (UTM) underwater. The large, bright display with Live A-scan is easily viewable by both the diver and his camera – even in the poorest visibility. With only two buttons to press, the gauge is very easy to navigate through an intuitive, user-friendly menu. Ideal for hull UTM inspections, civil engineering, marine structures, offshore platforms, underwater structures,pipelines and equipment, UWILD or IWS class surveys.

We use our Ocean Reef Full-Face Mask for communication with surface while inspection is taking place to ensure precise and efficient way of conducting our inspections. Our mask features a anti-fogging lens that provides optimal visibility underwater, allowing inspectors to focus on their work without distractions. With our full-face mask, inspectors can perform ultrasonic thickness measurements with confidence and precision, even in challenging conditions.
