    Eddy Current: Eddy current testing can find defects through paint coating with prior marine growth removal.
  • Ultrasonic Testing (UT): This is a common and highly effective non-destructive testing (NDT) method used to inspect the material of the internal structure and detect internal defects or irregularities. This technique uses high-frequency sound waves to examine a material’s internal structure without causing any damage.

  • Leak Testing Inspection: In Leak Testing, inspectors apply pressure to detect defects in an object that may be causing leaks.

  • Visual NDT (VT): Inspectors perform Visual Testing by examining a material or asset directly, often using flashlights indoors to enhance visibility. Visual Testing can also be done remotely using tools like inspection cameras (RVI).

  • Radiography NDT (RT): Inspectors use gamma or X-rays to find imperfections in materials. Radiography Testing reveals details like changes in density that are hard to see with the naked eye.
  • Acoustic Emission NDT (AE): Inspectors use acoustic emissions to identify defects in materials. During Acoustic Emission Tests, they listen for bursts of sound caused by these defects. By analyzing the intensity, location, and timing of these sounds, they can gather details about possible issues within the material.
  • Full Inspections: NDE Offshore conducts detailed dropped object inspections to identify and diminish possible threats within your onshore/offshore facilities. This is done to prevent accidents and obtain a safer working environment.

When working offshore, not all hazards come from what we see—they often come from what we don’t. Dropped objects remain a persistent risk on installations and vessels, largely because of a simple human tendency: we focus on the task in front of us, rarely looking up unless prompted.

On any given deck, crews are rightly focused on tools, controls, and immediate work scopes. But above them exists a layered environment of scaffolding, piping, cranes, and stored equipment—each with the potential to become a falling hazard if not properly secured. A loose fitting, an unsecured tool, or overlooked debris can quickly turn into a serious incident.

This is where planned dropped object surveys become essential. Relying on routine awareness alone is not enough. Structured, periodic inspections—specifically aimed at identifying and mitigating overhead risks—help counteract human blind spots. These surveys systematically check for unsecured items, degraded fixings, missing secondary retention, and poor storage practices before they result in harm.

Oliver Garcia, HSCE Manager, NDE Offshore

While tool lanyards, secondary retention, and good housekeeping are critical controls, they are only effective when supported by deliberate and proactive verification. Planned surveys create that discipline. They force teams to stop, look up, and challenge assumptions about what is “safe.”

Dropped object prevention is not just about reacting to hazards—it is about anticipating them. And in an environment where people don’t naturally look above, planned surveys are what ensure that someone always does.

      geotechnical investigation, sampling NDE Offshore

      Subsea projects can be complex, depending on the shape, the size, and the weight of the installed material.

      We always start by defining the end goal of your project. Once we know your development plans, the location, and the water depth, we can create the plan for the seabed survey. Subsea projects can be complex, depending on the shape, size, and weight of the installed material. We can determine the coverage and type of survey required.

      There are two main categories of survey methods used to characterize the seabed. The first is geophysics, which uses an acoustic source and reflections. The other fundamental option is geotechnical investigation, which involves drilling to penetrate a sampling device into the seabed. This is an intrusive process. In such projects, we extract high-quality samples from the subseabed and then undertake a range of further examinations.

      Safety inspection worker

      NDE Offshore can perform the following surveys:

      Multibeam Echo Sounder Survey (MBES)

      A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.

      Side-scan uses a sonar device that emits conical or fan-shaped pulses down toward the seafloor across a wide angle perpendicular to the path of the sensor through the water, which may be towed from a surface vessel.

       

      The Seabed Survey Data Model (SSDM) is an industry-standard for how seabed survey data is stored and managed by oil and gas companies. The International Association of Oil & Gas Producers (IOGP) developed and published this standard in October 2011.[1] Many surveys have been successfully delivered in SSDM.

      It is concerned with foundation design, construction, maintenance, and decommissioning for human-made structures in the sea. Oil platforms, artificial islands, and submarine pipelines are examples of such structures. The seabed has to be able to withstand the weight of these structures and the applied loads. Geohazards must also be taken into account.

      Mapping Seabed Morphology and Sub-Seabed Conditions

      Detailed depiction of the seabed’s physical condition and the layers beneath it.

      Profiling Geological Appearances

      Identification and analysis of geological planning to support engineering design and ensure stability.

      Geohazard Detection

      Early identification of potential geohazards, such as faults or unstable sediments, to diminish risks during construction.

      Reference for Geotechnical Investigations

      NDE Offshore survey reports are a qualitative risk analysis tool for assessing the impact and likelihood of identified anomalies on the inspected platforms / subsea structures.

      Geotechnical surveys are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is called a site investigation.

      Using advanced remote sensing technologies, we tailor our approach to suit the specific characteristics of each site. This ensures that we deliver solutions that are not only suitable and safe but also sustainable.

      A ground investigation is a detailed method used to examine the conditions of a site’s subsurface. It involves a range of techniques to gather essential information about the soil, rock, groundwater, and other geological features in the area.

      NDE Offshore Offers:

      • Core sampling
      • Laboratory testing
      • 3D ground modeling
      • Cone penetration tests
      • Mechanical drillings

      NDE Offshore specializes in geophysical surveys to collect the precise data design engineers need for the successful installation of offshore structures, subsea cables, and pipelines. These surveys provide essential insights for informed project planning and execution.

      Applications of Geophysical Survey Data:

      1.Analyze the Seabed and Sub-Seabed Conditions

      Detailed characterization of the seabed’s physical shape and the layers beneath it.

      2.Outlining Geological Features

      Identification and analysis of geological structures to support engineering design and ensure stability.

      3.Geohazard Detection

      Early identification of potential geohazards, such as faults or unstable sediments, to eliminate risks during construction.

      4.Reference for Geotechnical Investigations

      Providing a foundational seabed and sub-seabed reference guide for further geotechnical investigations.

      NDE Offshore delivers accurate and comprehensive geophysical data to be used as decision support when designing and installing critical offshore infrastructure. The data ensures that the project is safe, efficient, and successful..

      Pipeline route surveys are performed to determine the feasibility of a proposed pipeline route and to identify any potential environmental or social impacts that may affect its construction and operation.

      A pre-lay survey: This essential task is typically carried out as a preliminary step before the installation of subsea cables or pipelines. A post-lay survey: After pipe or cable laying, it is essential to perform a post-lay survey to verify the condition of a pipeline or cable through video footage.

      NDE Offshore offers extensive construction support services to ensure the safe and efficient installation of offshore assets. Our approach relies on precise surface and subsea positioning data, enabling accurate placement and secure installation of both surface and subsurface assets.

      Key Benefits of Our Construction Support:

      • Enhanced Accuracy: Using advanced positioning technologies, we ensure offshore assets are installed exactly where they are needed.
      • Safety Focus: Our methods prioritize safety during the installation process, minimizing dangerous risks to personnel and equipment.
      • Extensive Support: From initial planning to final placement, we work closely with clients to meet project requirements.

      NDE Offshore applies Remotely Operated Vehicles (ROVs) to perform detailed subsea inspections, mapping, and condition assessments of underwater assets. ROVs facilitate complex exploration and development in difficult and deep-water areas. ROVs, controlled remotely from the surface, are highly maneuverable and equipped with advanced imaging and sensor technologies, providing:

      • High-resolution video and still imagery
      • Subsea mapping and measurements
      • Condition monitoring of subsea assets

      For nearshore operations, NDE Offshore utilizes self-elevating platforms (SEPs) for geotechnical surveys and shallow-sea survey boats customized for hydrographic and geophysical surveys in coastal waters.

      Photogrammetry surveys gather measurements and data about an object by analyzing the change in position from two different images, using things like perspective, advanced processing software, and photo analysis to get the job done. It can happen on the ground or in the air.

          As with all projects, detailed planning before the start is crucial to achieving the best and most efficient result.

          There are different diving techniques, here we list a few of them.

          Surface Supplied Diving 

          Air Diving:

          Air diving is the most common and least complicated diving technique. It can be performed from 0 to 50 meters, but it is at the deeper end of the scale, with very limited bottom time.

          Nitrox Diving:  

          Nitrox is a mixture of nitrogen and oxygen in different proportions than the composition of air. Breathing a gas with higher oxygen content than air allows longer bottom time without incurring a higher decompression obligation. This is because the partial pressure of nitrogen (rather than depth per se) and time decide the table depth.

          By substituting some of the nitrogen with oxygen it is possible to decompress according to a shallower table depth.

          Mixed Gas Diving:

          Mixed Gas diving refers to replacing the breathing gas of air/nitrox with a mix of Helium and Oxygen. The mix is called Heliox.

          Cost Heliox

          Because of the expensive gas, Heliox has to be premixed at a gas factory and transported to the site in gas quads.

          Due to the cost of Mixed Gas diving, it is a cost-efficient solution at 40-50 meters of water depth.

          Depth:  Although diving even up to 150 meters of depth is possible, the possible bottom time at the deeper end of the scale is significantly less. Deeper mixed gas diving is only suitable for uncomplicated short jobs rather than prolonged diving.

          Saturation Diving

          When diving to depths of 40-50 meters to perhaps more than 100 meters, the best option from a working perspective is to use saturation diving techniques. 

          Saturation diving means the diver lives in a pressurized chamber and travels to and from the worksite in a pressured diving bell. In practical terms, this means that the diver only has to be pressurized down to actual working depth once during his entire work period. He will remain under this pressure throughout the job (which can last up to 30 days) in the chamber, and then when the job is complete, he is swapped out and will decompress in the chamber. 

          Recourses, equipment, and personnel: 

          Compared to other diving techniques, saturation diving is more demanding in terms of equipment requirements and personnel qualifications. Typically, 6 to 8 20-foot containers are required for a single operation. The workforce needed to manage a dive site typically ranges between 16 and 20 individuals, varying based on the specific project requirements.

          Efficiency: Bottom time 

          However, although there are several more personnel and equipment, the operation is much more efficient since a team using a mobile saturation Dive system can have up to 22 hours of efficient bottom time every 24 hours.

          Comparing the different diving techniques, we can conclude that every project has specific needs and prerequisites.

          To decide what type of diving to use, the following points need to be considered:

          • Depth of work
          • Type of work that needs to be done.
          • Type of vessel that is intended to be used.
          • 12/24-hour operation
          • Contingency/Emergency needs (Including specific Risk Assessments, etc)
          • Need for continuous work on the seabed.
          • Specific Qualification needs of personnel and experience.
          • Additional resources including personnel needed (electrical Power plants, Compressors, Cranes, Deck crew, etc) 

           

          As in all projects, detailed planning before the start is crucial to achieving the best and most efficient result.
