ASTM F2926-18(2022) PDF

Overview

ASTM F2926-18(2022), titled Standard Guide for Selection and Operation of Vessel-mounted Camera Systems, provides comprehensive guidance for selecting and operating camera-based remote sensing systems installed on vessels for the detection of oil on water. Developed by ASTM International, this standard is a key resource for emergency response teams, oil spill recovery operators, and marine safety professionals engaged in oil spill response and environmental monitoring.

The standard covers criteria for the selection of remote sensing camera systems, recommendations for their deployment, and considerations for varying types of oil and water environments. It addresses the use of different camera technologies-including infrared (IR), visible spectrum, ultraviolet (UV), and night vision-and discusses their advantages and limitations for specific applications.

Key Topics

• Purpose of Vessel-mounted Camera Systems

  • Tactical imaging of oil spills around the vessel
  • Enhanced detection of oil slicks, especially in low-visibility conditions and at night
  • Identification of areas with the highest oil concentration
  • Operational support for deploying skimmers, booms, and other response equipment
  • Extending the duration of response operations to include darkness and adverse weather
  • Improved guidance for operational crews to locate and track slicks

• Types of Camera Technologies

  • Visual Cameras: Effective under daylight with familiar operation, but limited by low-light and sometimes challenged to distinguish oil from background water surfaces.
  • Infrared Cameras: Useful in differentiating oil thicknesses via thermal contrast, particularly effective for fresh or thick oils, with certain limitations relating to weather and lighting conditions.
  • Ultraviolet Cameras: Capable of detecting very thin oil sheens; performance requires sufficient ambient light and may be susceptible to interference from sun glint and biological materials.
  • Night Vision Cameras: Enhance visibility in complete darkness, providing situational awareness but lacking a unique oil signature.

• Operational Considerations

  • Proper mounting height and angle (often near Brewster’s angle, approx. 53° from vertical) for optimal field of view and avoidance of water surface reflection
  • Importance of camera stabilization in rough seas
  • Use of pan, tilt, and zoom capabilities for maximizing coverage and targeting slicks
  • Combining multiple camera types for improved detection and situational awareness

• Limitations and Challenges

  • Inability of current sensors to provide quantitative data on oil thickness
  • Variability in detection capabilities due to oil weathering, lighting, wind, and background interference
  • Necessity for pre-spill planning and reporting to guide camera system deployment and selection

Applications

• Oil Spill Detection and Response: Supporting tactical decisions during marine and freshwater oil spill incidents by providing real-time visual data to operational crews.
• Environmental Monitoring: Routine surveillance in harbors, shipping lanes, and sensitive environmental zones for early detection of oil-on-water threats.
• Extended Operation Conditions: Enabling clean-up and monitoring activities during night and periods of low visibility, thus minimizing environmental impact and optimizing resource deployment.
• Training and Preparedness: Assisting organizations in developing effective oil spill response strategies and ensuring their personnel are equipped to utilize vessel-mounted camera systems optimally.
