The technique of measuring a structure or material’s thickness in the marine environment, notably the top side of offshore platforms, ships, and other marine structures, is known as marine/topside thickness measurement. For the marine structures’ structural security and safety, the thickness measurement is crucial. The thickness of marine/topside structures can be measured using a variety of techniques, including:

  • High-frequency sound waves are used in the non-destructive testing technique of ultrasonic thickness measuring to gauge the thickness of a material. A sound wave is sent through the material using an ultrasonic transducer that is placed on the surface of the structure. The opposing surface of the structure will reflect the sound wave, and by measuring how long it takes for the sound wave to travel through the material, the thickness of the material may be determined.
  • A non-destructive testing technique called magnetic flux leakage employs magnetic fields to find faults or changes in material thickness. The process entails providing a magnetic field to the material and mounting a magnetic sensor on the surface of the construction. The sensor will identify any alterations in the magnetic field brought on by a fault or a change in thickness.
  • Another non-destructive testing technique that uses electromagnetic induction to find changes in material thickness is eddy current testing. The process entails running an alternating current through a coil that is attached to the structure’s surface. Eddy currents will be created by the current, and they will be impacted by adjustments to the material’s thickness. Eddy current variations can be observed and utilized to determine the thickness of the material.
  • A quick and easy way to gauge the thickness of marine/topside structures is through visual inspection. The technique entails measuring the thickness of the material at various spots on the construction using a ruler or a thickness gauge. The thickness of thin materials or easily accessible places can be measured using this technique. 


Need for Marine/Top side thickness measurement in Marine offshore inspection

The requirement for marine/topside thickness measurement in marine offshore inspection results from the extreme environmental conditions offshore structures are subject to, such as exposure to seawater, waves, and wind, which can cause corrosion and material degradation. Furthermore, offshore buildings are vulnerable to deterioration over time because they are made to operate in challenging environments for extended periods of time. Multiple factors make measuring marine/topside thickness crucial:

  • Corroded or wall-thinning marine constructions may be at danger of structural failure, which could pose major safety risks to anybody working on the structure or nearby. The thickness of the structure is measured to make sure it is suitable for use.
  • To make sure that the offshore constructions adhere to industry norms and regulations, thickness measurements are needed. To make sure marine constructions are safe to use, several rules demand yearly inspections and thickness measures.
  • Measurements of thickness offer useful data for administration and planning of maintenance. Knowing a structure’s thickness enables planning of replacement and maintenance schedules, which can assist prevent unplanned downtime and reduce maintenance costs.
  • For the asset management of marine constructions, thickness measurements are crucial. Making decisions concerning the structure’s maintenance, replacement, or decommissioning requires knowledge of this information.


Efficiency and precision of Marine/Top side thickness measurement

The efficiency and precision of marine/topside thickness measuring have increased dramatically in recent years. The way thickness measures are collected has completely changed because of the adoption of cutting-edge technologies like ultrasonic testing, magnetic particle testing, and laser scanning, which produce data that are more accurate and dependable. A frequently utilized technology for measuring marine/topside thickness is ultrasound testing.

It entails irradiating the material under test with high-frequency sound waves and timing how long it takes for the waves to return. The thickness of the material is determined using this data. Ultrasonic testing is a quick and reliable method of measuring since it is non-destructive and easy to carry out. Another technique for measuring marine/topside thickness is magnetic particle testing. It entails adding iron particles to the surface and magnetizing the item being examined. The particles will congregate in any regions where there is corrosion or thinning, suggesting a flaw.

This technique is extremely accurate and sensitive, detecting flaws as small as 0.001 inches. For measuring marine/topside thickness, a more current technology called laser scanning is used. It entails scanning the material’s surface with a laser to build a 3D representation. This model is used to precisely measure the material’s thickness. Laser scanning is advantageous for complicated constructions because it is extremely accurate and can produce a complete model of the substance being evaluated.


Applications and benefits of Marine/Top side thickness measurement

The measurement of marine/topside thickness has several uses and advantages in a variety of industries, such as offshore oil and gas, shipbuilding, and marine transportation. Marine/topside thickness measurement is employed in the offshore oil and gas sector to guarantee the structural integrity and security of offshore buildings such as platforms, pipelines, and storage tanks. The measurements are crucial for locating corrosion and material deterioration so that they may be fixed or replaced before they pose a risk to safety. The measures’ data can be used for asset management and maintenance planning, which can lower costs and downtime.

Marine/topside thickness measurement is used in the shipbuilding sector to guarantee adherence to industry norms and regulations. The measurements are essential for locating regions of deterioration, corrosion, and fatigue that may affect the vessel’s structural integrity and functionality. Using the information gathered from the measurements, maintenance and repairs can be planned in order to increase the vessel’s lifespan. Marine/topside thickness measurement is used in the maritime transportation sector to guarantee the security of the ship and its cargo.

The measurements are essential for locating regions of corrosion and material deterioration because they can result in structural failure and present environmental risks. Plans for maintenance and repairs are made using the information gathered from the measurements, which can assist lower costs and downtime.

Increased safety, adherence to rules and standards, better planning and administration of maintenance, and improved asset management are all advantages of marine/topside thickness measuring. The measures assist in identifying potential safety risks and enable prompt repairs, which can reduce the risk of accidents and expensive downtime. Additionally, the measures guarantee adherence to industry norms and regulations, which can help prevent fines and other legal repercussions. The information gathered from the measurements can be used for maintenance management and planning, which can lower costs and increase asset longevity. 


Scope and significance of Marine/Top side thickness measurement

Marine/topside thickness measurement has a huge range and is very important in many different sectors. The measurement is used to establish the thickness of the steel or other material used in ships, maritime transportation vehicles, and offshore structures. This information is essential for evaluating the structure’s integrity, spotting possible issues, and organizing maintenance and repairs.

The importance of marine/topside thickness measurement is found in its capacity to safeguard the environment, ensure the safety of workers in offshore constructions or on ships, and prevent expensive damage to the structure or vessel.
