Pressure Vessel Inspections

Pressure Vessels used in Australia are subject to periodic inspection as determined by AS3788 as well as the commissional, re-commissioning or de-commissioning inspection.  The owner of the plant equipment is responsible for ensuring that these inspections including In-Service Inspections are carried out.  All Pressure Vessel inspections must be carried out by a competent person that specializes in pressure vessel testing.  The in-service inspection takes into account where the product is used and the potential for failure in the future. AS3788 also enables risk based inspection to be used but is subject to agreement between the owner and inspection body, justification of any variation of inspection practice from AS3788 and therefore inspection periods can be increased as long as the increase can be justified and agreed by the inspection body.

Ozaquatec’s technicians can inspect all types of Pressure Vessels, including Air Receivers, Autoclaves, Separators, Blast Furnaces, Drilling Rig Misters, Gaseous Systems and Hydraulic Accumulators.

Regularity of Inspections

Registered Pressure Vessels require in-service inspection externally every two years and internally every four years. During this process the Vessels are inspected thoroughly, pressure gauges and safety valves are replaced or tested as required. Gaskets and ball valves may also need to be replaced during this inspection. A detailed report is then issued to each client for each Vessel. This report outlines the current condition of the plant equipment as well as points of ultrasonic testing, degradation and installed gauges, safety relief valves etc.

What type of equipment requires registration?

Pressure vessels categorized as hazard level A, B or C under the criteria mentioned in AS 4343, as in force on 1 July 2000, other than (a) refillable gas cylinders mentioned in AS 2030 and (b) LP gas fuel vessels for automotive use mentioned in AS 3509 and (c) serial produced vessels mentioned in AS2971.

Who must register plant equipment?

The owner is responsible for registration of registrable plant. The owner includes any person leasing the plant or a mortgagee in possession of registrable plant.  **An owner of registrable plant equipment must not use the plant, or permit the plant to be used at a workplace unless the plant has been registered.**  It is also the responsibility of the owner, if applicable, to ensure the plant design is registered in accordance with Schedule 4 of the Workplace Health and Safety Regulation 2008.

How to register plant equipment?

Owners who want to register plant equipment must apply to Workplace Health and Safety Queensland on a Form 8 – Application for registration of registrable plant.  Plant registration does not allow usage of the plant, if Schedule 4 of the Workplace Health and Safety Regulation 2008 is not complied with.  Registration is valid from the date stated on the application up to the 31st January in the following year. Once application is received by WHSQ, an invoice for the fees is produced and payable.  Plant registration expires on 31st January of each year. Workplace Health and Safety Queensland will send out a Form 25 – Application for Renewal of Registration prior to the expiration.
