ABS: Guidance for Remote Inspection Technologies

Classification society ABS has published new guidance notes detailing best practices for their use on class surveys and non-class inspections.The Guidance Notes on the Use of Remote Inspection Technologies cover pilot-operated unmanned aerial vehicles (UAV), remotely operated underwater vehicles (ROV) and robotic crawlers, collectively known as remote inspection technologies (RIT).“The use of RITs can reduce risk for Surveyors and inspectors by lessening the need to access potentially hazardous locations at height, or other hazardous inspection areas. This guidance facilitates safer, more

Providing key AUV operations experience and working within this diverse group to integrate the various sub-systems into a complete USV / AUV system is exactly how OFG operates best; as part of a team developing and deploying leading-edge subsea mapping and inspection technologies.”   The GEBCO-NF Alumni Team’s data processing solution utilizes Teledyne Caris components and the development work to meet the requirements of the Shell Ocean Discovery XPRIZE has been undertaken with assistance from Teledyne CARIS.

In addition, this creates a safer way of working for surveyors,” Viteri noted.    “We are happy to see that customers continue to positively receive this alternative and view this as a model for future inspection technologies.”   The camera and software system are fully operational and licensed by an independent provider.

company has developed a strategy in tackling these inspection projects. “Our progressive inspection philosophy is a guided examination of mooring systems that focuses on known problems and failure modes,” said Hall. “When anomalies, wear or damage is identified, progressive inspection technologies are used to zero in on the problem and identify its characteristics and operational implications.” Welaptega has developed several innovative schemes to carry out its inspections. It specializes not only in chain and rope measurement systems but underwater asset 3D video and 3D modeling
