(a) is the holder of a valid fifth class power engineer’s certificate and for at least 12 months, has operated as a chief engineer an oilfield once‑through boiler or oilfield‑once through boiler plant with a capacity greater than 250 kilowatts

(b) is the holder of a valid fifth class power engineer’s certificate and for at least 12 months, has operated an oilfield once‑through boiler or oilfield once‑through boiler plant with a capacity greater than 1 000 kilowatts or any other high pressure boiler or high pressure boiler plant with a capacity of not less than 250 kilowatts

(c) for at least 12 months, has assisted in the operation of an oilfield once‑through boiler or oilfield once‑through boiler plant with a capacity greater than 2 000 kilowatts or any other high pressure boiler or high pressure boiler plant with a capacity of not less than 1 000 kilowatts

(d) is the holder of a valid fifth class power engineer’s certificate and, for at least 24 months, has operated as chief engineer a low pressure boiler or low pressure boiler plant with a capacity greater than 750 kilowatts, with the capacity of the plant calculated as the aggregate capacity of all boilers installed in the plant

(e) for at least 24 months, has assisted in the operation of a low pressure boiler or low pressure boiler plant with a capacity greater than 1 500 kilowatts, with the capacity of the plant calculated as the aggregate capacity of all boilers installed in the plant

(f) has successfully completed an approved full‑time course in power engineering that:

        (i) includes operating experience; and

        (ii) leads towards a fourth class power engineer’s certificate

(g) is a graduate engineer that:

        (i) for at least 2 months, has acquired experience in the operation of a high pressure boiler or high pressure boiler plant with a capacity greater than 500 kilowatts; (

        ii) for at least 2 months, has acquired experience in the operation of a low pressure boiler or low pressure boiler plant with a capacity greater than 1 000 kilowatts;

        (iii) for at least 6 months, has performed in a role acceptable to the chief inspector on the design, construction, installation, repair, maintenance or operation of pressure equipment; or

        (iv) has successfully completed an approved operating experience course lab leading towards the fourth class power engineer’s certificate

(h) for at least one‑half of the period mentioned in clause (a), (b) or (c), has operated in the role described in that clause and, for at least 12 months, has performed in a role acceptable to the chief inspector on the design, construction, installation, repair, maintenance or operation of pressure equipment; or

(i) has at least 12 months’ experience as a process operator in a role acceptable to the chief inspector and has completed an approved course in power engineering leading towards a fourth class power engineer’s certificate.

Six months’ credit will be granted towards fulfilment of the operating experience requirement set out in clause (1)(a), (b), (c), (d) or (e) for the successful completion of an approved course in power engineering leading towards a fourth class power engineer’s certificate.
