Underwater Skills

Program Learning Outcomes

This Seneca program has been validated by the Credential Validation Service as an Ontario College Credential as required by the Ministry of Colleges and Universities.

As a graduate, you will be prepared to reliably demonstrate the ability to:

  • Competently demonstrate through practice the skills and knowledge, including professionalism, as described in Clause 9 of the Competency Standard for Diving Operations (CAN/CSA-Z275.4), including a thorough working knowledge of:
    • Canadian federal and provincial diving regulations, standards and industry best practices pertaining to unrestricted surface-supplied diving;
    • the physical laws governing diving operations, including the states of matter, the properties of gases and liquids, and the units of measurement;
    • the principles of compression and decompression that affect divers and the implications for routine operations, emergencies, and therapeutic recompression, including the use of the diving tables;
    • the hazards of differential pressures as well as lockout procedures;
    • the principles, applicable legislation, operation and use of rigging equipment used both on the surface and under water in support of diving-related operations;
    • the function, operation, and safety requirements for hand, pneumatic and hydraulically-activated tools;
    • the principles of operation of topside welding and oxy-arc cutting equipment and the associated safety precautions and legislation;
    • the principles of underwater electric arc-welding and exothermic cutting equipment and the associated safety precautions and legislation.
  • Safely perform at least 50 surface-supplied dives in various environmental conditions and locations and for various purposes, with a bottom time totalling at least 50 hours at depths of up to 50 metres.
  • Assess the causes and manifestations of pressure-related diseases and conditions (i.e. pulmonary barotrauma, gas embolism, the effect of pressure on gas-filled cavities, and decompression illness) and diagnose and deliver treatment as appropriate.
  • Administer therapeutic oxygen safely in appropriate situations.
  • Operate a hyperbaric chamber safely and efficiently while treating occupants using accepted tables.
  • Set-up, operate, and maintain various types of surface-supplied diving equipment demonstrating sufficient knowledge and skills to ensure safe underwater operation, including the principles and operation of high- and low-pressure air compressors, their associated equipment, and applicable safety requirements.
  • Dive safely and competently using different types of surface-supplied diving equipment in open water of varying depths, bottom conditions, and water visibilities.
  • Employ a job-specific understanding of WHMIS.
  • Describe procedures, checks, decontamination, and equipment modifications for diving in contaminated environments.
  • Effectively use all commonly used modes of underwater communication safely.
  • Safely and effectively employ surface-supplied systems in the performance of underwater tasks and mitigate problems related to such tasks.
  • Describe the types of explosives available for underwater use, the physics and the hazards of underwater blast injuries, safe handling and use.
  • Describe and differentiate between construction methods used in diving operations and the elementary principles and procedures involved in salvage operations.
