Such way as an Oikonomia,can be used only in the extreme urgency(no any possibility to perform triple immersion ,and the candidate(catechumen)is dying).
without such especial complexion,the sacramental oikonomia SHOULD NOT be used,and if anyone was baptised in such way without warrant(an extreme urgency),his "baptism" should not be considered valid,and he should be baptized in canonical and orthodox manner.
