Waterjet services for refineries and petrochemical plants
Dezu delivers the refinery scopes that need water instead of flame or impact — hydro demolition, spark-free cold cutting, tank and floating roof seal services, and heat exchanger cleaning — as the specialized subcontractor international EPC chains select. Delivered on Philippine petrochemical expansions and a Pacific fuel terminal.
What does Dezu do inside refineries and petrochemical plants?
The scopes that need water instead of impact or flame: hydro demolition for structural repairs, spark-free cold cutting on tanks and lines in hydrocarbon service, storage tank cleaning and floating roof seal replacement, and heat exchanger tube cleaning during turnarounds. All delivered by a PCAB-licensed contractor with a DOLE-approved safety program.
Has Dezu delivered under EPC contract chains?
Yes. On a petrochemical plant expansion, Dezu delivered specialized hydro demolition under an international EPC joint venture and a major Philippine construction company — exposing a shear key so a structure that tilted from ground settling could be lifted and corrected. International EPCs repeatedly select Dezu as the specialized subcontractor.
Why do hydrocarbon facilities specify waterjet methods?
Because water carries no ignition source and no heat. Cold cutting opens tanks and cuts steel without gas-freeing-scale hot-work risk; hydro demolition repairs concrete without vibration damage; high pressure cleaning strips fouling without sparks. In a live plant, the method that cannot ignite anything is the method that keeps the schedule.
