A geophysical survey is a scientific method of analyzing the subsurface of the earth using physical measurements such as magnetism, gravity, seismic waves, or electrical currents. Geophysical surveys are typically used to locate and map underground structures, geological formations, or natural resources such as oil, gas, or minerals. Geophysical surveys involve the use of specialized instruments and data collection techniques to capture and analyze physical measurements of the earth's subsurface. Several geophysical methods may be used to collect information about the subsurface, and the selection of the method will depend on the objectives of the survey and the characteristics of the terrain. Seismic surveys are among the primary methods used for geophysical investigation. They utilize sound waves to map subsurface structures and estimate underground rock formations, mineral deposits, or hydrocarbon reserves. Another important technique is electromagnetic or conductivity surveying, which maps the electrical conductivity of the earth's subsurface. Geophysical surveys are widely used in different industries including mining, petroleum, construction, and civil engineering to obtain a better understanding of subsurface conditions. Geophysical survey results can provide information about soil type, rock strata, faults, underground water flows, and any other characteristics of the subsurface. In summary, geophysical surveying plays a critical role in understanding the earth's subsurface. The data gathered from geophysical surveys can help decision-makers in various industries to better plan, design, and execute projects related to infrastructure, energy production, and natural resource exploration. #survey #geophysical #offshorejobs #offshore #offshorewind #offshoreenergy #rov Visit our website to learn more www.quasarsubsea.com

Subsea Survey Equipment Requirements : 1.Sub-Bottom Profilers The sub-bottom profilers are tested under tow at each transmitting frequency available using maximum power and repetition rates for a period of half an hour. During mobilization, the outgoing pulse from the transducer /seismic source is monitored to ensure a sharp, repeatable signature utilizing a suitably calibrated hydrophone. The monitored pulse shall be displayed on board on an oscilloscope with storage facility and a copy generated for approval. The pulse should conform to the manufacturer’s specifications and a printout of the signature should be included in the final report. A static or dynamic pulse test may be used to demonstrate a stable and repeatable seismic source signal producing a far-field signature at a tow depth of 3.28 ft (1 m): • Pulse in excess of 1 bar meter peak-to-peak; • Pulse length not exceeding 3 ms; • Bandwidth of at least 60 to 750 Hz (–6 dB); • Primary to secondary bubble ratio > 10:1. 1.1. High-Resolution Sub-Bottom Profiler A high-precision sub-bottom profiler system is provided and operated to obtain high-resolution data in the first 10 m of sediment. The operating frequency and other parameters are adjusted to optimize data within the first 5 m from the seafloor. Vertical resolution of less than 1 m is required. A dual-channel “chirp” sub-bottom profiler may be capable of operating within the 3.5 to 10kHz range with a pulse width selectable between 0.15 and 0.5 m and transmitting power selectable between 2 and 10 kW. The system is capable of transmitting repetition rates up to 10 Hz. Transmitting frequency, pulse length, power output, receiving frequency, bandwidth, and TVG (Time Varying Gain) are adjustable. A heave compensator is required when using a sub-bottom profiler. The system may either be collocated with the side-scan sonar system utilizing the same tracking system or hull mounted/over the side and reference the ship’s navigation antenna. Onboard interpretation of subbottom profiler records is carried out by a geophysicist suitably experienced in interpretation of such records. 1.2. Low-Resolution Sub-Bottom Profiler The generic term mini air gun covers a range of available hardware that uses explosive release of high-pressure air to create discrete acoustic pulses within the water column, of sufficient bandwidth and high-frequency component to provide medium-resolution data for engineering and geohazard assessment. The system is capable of delivering a stable, short-duration acoustic pulse at a cycle repetition rate of 1 sec. The hydrophone comprises a minimum of 20 elements, linearly separated with an active length not exceeding 32.8 ft(10 m), with a flat frequency response across the 100 to 2000Hz bandwidth #offshore #mechanicalengineering #oilandgas #surrey #subseaengineering

Is this a positive indicator of a high-demand industry, or a concern that we failed to engage with pre-university students during recent downturns and are now facing the consequences? Over 10 Surveyor positions and other specialized roles, such as Geophysicists, Engineers, and Processors, are currently advertised with The Hydrographic Society UK & I alone. Many more opportunities are available beyond these listings. Whose responsibility is it to ensure a steady stream of graduates are entering the subsea industry to support growth and replace retirees? Considering that the process of hiring, training, and gaining field experience to transform a graduate into a proficient Surveyor or Geophysicist can take over a year, should clients share some of this burden? Is there a more efficient way to address this challenge?
