How Long Does It Take to Install an Industrial Gas System? A Real-World Timeline from Survey to Commissioning

13/10/2026

One of the first questions factories ask when considering a gas system investment is: how long will it take to commission? The answer directly affects production planning — especially when expanding capacity, replacing an aging system, or preparing for an order with a fixed deadline.

The actual timeline depends on the system type (LPG, CNG, or LNG), scale, and fire-safety regulatory requirements. Below is the estimated timeline by system type and the key milestones in DATA Energy's implementation process.

Timeline by System Type

Step	LPG	CNG	LNG
1. Site survey & preliminary design	3–5 days	3–7 days	5–7 days
2. Equipment & material procurement	6–8 weeks	8–10 weeks	10–12 weeks
3. On-site construction	2–4 weeks	2–4 weeks	2–4 weeks
4. Fire-safety review & handover	1–3 weeks	1–3 weeks	2–4 weeks
Total estimated time	9–15 weeks	9–15 weeks	14–20 weeks

Estimated timeline for a mid-scale system in an industrial zone. Actual timelines vary by project conditions.

What Happens at Each Milestone?

Site survey & preliminary design (3–7 days): technicians survey the site and propose an installation plan.

Equipment & material procurement (6–12 weeks): technical documentation is finalized and equipment is procured; this is the longest phase, especially for LNG, which requires imported equipment.

On-site construction (2–4 weeks): installation is carried out at the factory, coordinated to avoid disrupting ongoing production.

Fire-safety review & handover (1–4 weeks): design review and commissioning inspection per Decree 105/2025/NĐ-CP before the system goes into operation.

What Affects the Timeline?

Site readiness: Pre-leveled, concreted, and fenced tank areas speed up installation. Groundwork from scratch adds 1–2 weeks.

Fire-safety documentation: Clear factory construction records simplify inspection. Processing speed also varies by locality.

System scale: Larger tanks take longer to install. LNG requires specialized imported equipment with longer procurement lead times than LPG and CNG.

Time of year: Q4 is peak construction and production season — labor and equipment become scarcer, which can extend certain steps. Factories planning a year-end installation should start the process at least 2–3 weeks earlier than usual.
