  • Hazard Alert Poster 2000-14
    HAZARD ALERT Industry: Diving Age: 36 years Experience: 12 years Area: Central BC Diver killed during maintenance work A commercial diver was drawn into a 30" diameter aerator intake pipe while attempting to locate the screens for two fire pump intakes. The pulp mill hired a diving company to inspect and clean two intake screens in their industrial effluent pond. Both parties thought that the work had been planned and all hazards identified. The pumps for the two intakes to be worked on had been identified and locked out. The diver, after entering the water with zero visibility, thought he had located the fire pump intakes when he was drawn into a nearby aerator intake pipe. The screen for this intake pipe had broken off and the diver was pulled, head first, 80 feet up the pipe. As the aerator intake pipe had not been identified on the drawings used, the 35,000 litre per minute aerator pump had not been locked out. There were no visual markers on the surface of the pond to identify the aerator or fire pump intakes. Safe work practices: Before diving, a detailed risk assessment must be conducted by a qualified person, with specific knowledge of the worksite, to determine all hazards • Ensure there are accurate drawings (preferably on a master drawing) indicating all underwater equipment, piping, intakes, etc. for all underwater work • Ensure all underlying hazards have visual indicators (flagging or signage) on the surface • Ensure risk assessments, safe work procedures, lockout procedures, pre-work meeting documents, and accurate drawings are available and used by project co- ordinators and diving contractors working in underwater environments FATALITY 00–14 The WCB has a wide range of health and safety information.

  • Underwater Inspection Criteria
    NAVAL FACILITIES ENGINEERING SERVICE CENTER Port Hueneme, California 93043-4370 UNDERWATER INSPECTION CRITERIA By Shawn W. Kelly Naval Facilities Engineering Service Center 1100 23rd Avenue Port Hueneme, California 93043-4370 March 1999 Prepared for: California State Lands Commission Marine Facilities Division 330 Golden Shore, Suite 210 Long Beach, California 90802-4246 EXECUTIVE SUMMARY The Marine Facilities Division (MFD) of the California State Lands Commission (CSLC) is in the process of reviewing and formulating various design and inspection criteria for waterfront facilities. The MFD has a regulatory requirement to require a thorough examination of each marine terminal in the State to determine whether the structural integrity of the terminal, the oil transfer operations system, and the safety equipment are designed and being maintained in a safe working condition. To meet this regulatory objective the CSLC has developed a procedure for performing an in-depth structural and safety system audit of existing marine loading and discharge terminals located onshore, near-shore, and offshore California. These procedures apply to pier and wharf terminals, and offshore multi-point mooring marine terminals. The Naval Facilities Engineering Service Center (NFESC) has been tasked to provide input to the review and formulation of design and inspection criteria for waterfront facilities, based on the Navy’s extensive experience and expertise in this area. This document addresses the underwater inspection component of the overall effort. This underwater inspection criteria is intended to provide guidance to the CSLC on the inspection of the underwater components of a marine oil terminal facility with the intent on identifying structural damage or weaknesses that might affect the continued fitness-for-purpose of the terminal.

  • UNDERWATER INSPECTION and CONSTRUCTION SERVICES Underwater Inspections
    Underwater services UNDERWATER INSPECTION AND CONSTRUCTION SERVICES Underwater Inspections 294187 3425 INSPECTIONS Our team of over 30 ADCI certified divers have the latest technologies to aid them in gathering information in various types of underwater conditions. Whether the conditions are extreme temperatures, poor visibility or strong currents, we have the tools and personnel to respond to a wide range of challenges. » Bridges » Piers and dock facilities » Dams (FERC Part 12 and USCOE) » Pipelines Acoustic Imagery » Industrial facilities » Vessels When underwater visibility is limited, acoustic imagery can help clear things up. This technology uses » Intakes and outfalls acoustics to create an underwater image of the structure to help detect structural problems and scour issues. Typically these images can be combined with above water digital photography or CAD drawings to create a pictorial reference of the entire structure. Detailed Reporting We understand that an inspection is only as good as the information communicated. Brennan divers can investigate, record, and effectively report critical information. These reports contain detailed descriptions, CAD drawings, images, and underwater video documentation to help identify any structural concerns. Remotely Operated Vehicles Our ROV's can be used to gather information when underwater conditions are unknown. They can be outfitted with HD video systems and sonar imaging equipment to navigate and collect valuable information. These vehicles are ideal for pipeline penetrations, or deployment in conditions unsafe for diver entry. Bathymetric Surveys Brennan has a full time survey department with licensed hydrographers capable of providing georeferenced, 3-dimensional models of subaqueous structures and surfaces. This ability combined with a detailed dive inspection will leave little to the imagination.

What is a Bridge? Federal definition – A structure that provides passage on a public way that is 20 feet in span or longer measured along the centerline. State definition – A structure that provides passage on a public way that is 10 feet or greater in span measured along the centerline. Structures 10 feet to less than 20 feet are referred to as minor spans while structures 20 feet or greater are referred to as bridges. Skew Centerline Roadway SPAN Who Owns and Maintains these Bridges? MaineDOT owns and maintains all bridges and minor spans on state and state aide highways. MaineDOT owns and maintains all bridges on the local network that are not Low Use or Redundant Bridges (LURB). Check with the Region Management staff if you’re not sure of ownership.
