Safety & Risk Engineering Services
Studies that decide. Designs that comply. Protection you can prove.
Owners of terminals, plants and energy infrastructure face three questions: What can go wrong? Is my protection adequate? Can I prove it — to regulators, insurers and my own board? SATU’s engineering team answers all three — combining oil and gas safety methodology with hands-on fire-protection engineering, to NFPA, IEC and Thai law.
Fire Safety Assessment & Firewater Adequacy
Brownfield risk surveys of ageing plants and terminals — unsafe design, deteriorated protection, workplace hazards — with hydraulic firewater adequacy studies and a prioritised, costed upgrade roadmap.
Typical deliverables: hazard identification and fire scenario register; firewater demand calculation against the governing standard; hydraulic modelling of the existing ring main; a gap register ranked by risk with indicative remedial scope; and a findings report written to be handed to a regulator or insurer without translation.
We size firewater demand for the credible worst case rather than the historic one — the largest single tank plus exposure cooling to NFPA 15 at 10.2 L/min/m² over the shell, plus a hose and monitor allowance, and we check the stored reserve against what Thai law requires rather than what the pump can deliver for ten minutes.
Fire Protection Detailed Design
Detailed engineering to NFPA and Thai law — foam systems, deluge and water spray, hydrant networks, fire pumps and clean-agent systems (IG-100, CO₂, FM-200) for control rooms, substations and data centres — delivering drawings, calculations, BOQ, specifications and government cost estimates (ราคากลาง) ready for construction tender.
Typical deliverables: P&ID and general arrangement drawings; hydraulic calculations to NFPA 13 / 15 / 11 with the remotest-nozzle case proven; equipment datasheets and BOQ; technical specifications for tender; and a government cost estimate (ราคากลาง) with Factor F applied where the project is publicly funded.
Design and certification are delivered under a licensed professional engineer, as Thai law requires for fire protection works.
Fire & Gas Detection Engineering
Fire and gas detection system design and integration — detector selection and layout, cause-and-effect matrices and alarm logic, panel integration, commissioning and acceptance testing — delivered turnkey with Consilium detection systems, as engineered for marine terminal projects.
Typical deliverables: detector selection study and coverage layout; cause-and-effect matrix; alarm and voting logic; panel and PLC/DCS interface schedules; commissioning procedures and acceptance test records.
Detection technology is matched to the hazard rather than to a catalogue — flame detection where a hydrocarbon fire develops without smoke, gas detection where a release precedes ignition, and fibre-optic linear heat detection where a fire can start anywhere along a route such as a tank rim seal, conveyor gallery or cable tunnel. See our fire & gas detection systems for the equipment behind these designs.
Regulatory Compliance Packages
LPG tank-cooling verification to the Ministry of Energy regulation B.E. 2567 (at least 10.2 L/min/m², annual DOEB-witnessed testing), oil-terminal fire-safety compliance under the Fuel Oil Control Act, and annual test protocols with system performance verification. Our guide to the LPG tank-cooling rule sets out what the regulation requires and the deadline that has already passed.
Typical deliverables: compliance gap assessment against the governing regulation; recalculated cooling density and water reserve; certified hydraulic calculations; a witnessed test procedure and record pack; and an annual ITM plan the DOEB will accept.
The LPG rule is specific: at least 10.2 L/min/m² over the whole vessel surface, at least a 6 mm nozzle orifice at 1.4 bar or more at the remotest nozzle, a water reserve of at least 600 L/m² of tank surface under the 2564 ministerial regulation, and annual testing with records retained for inspection.
PFAS-Free Foam Transition
Fleet-wide AFFF to SFFF transition studies — foam selection and scoring to EN 1568, UL 162 and LASTFIRE, compatibility and proportioning checks, transition planning and disposal coordination — as delivered for major Thai pipeline and terminal operators. See our IMO 2026 PFOS foam ban compliance route and the SOLBERG PFAS-free ranges.
Typical deliverables: foam selection matrix scored against EN 1568, UL 162 and LASTFIRE fire-test evidence; compatibility review of seals, linings and pipework; proportioning verification before and after changeover; a cleaning and decontamination method statement; and a disposal route for the legacy stock with documentation.
Two things decide whether a transition holds up. The first is proportioning: a fluorine-free concentrate is more viscous than the AFFF it replaces, so the mixing rate must be re-measured and certified, not assumed — see our NFPA 11 compliance guide. The second is residual PFAS: without proper decontamination, fluorine leaches back out of pipework and system linings and shows up in the new foam, which is the rebound problem that catches sites out after a straight drain-and-fill.

Testing, Training & ITM
NFPA 25 inspection, testing and maintenance contracts, CO₂ cylinder and system hydrostatic testing, and annual performance tests — plus IMO OPRC Level 2–3 and port fire-team training delivered for government marine agencies.
Typical deliverables: an asset register with the inspection frequency each item actually requires; annual pump performance curves measured against the original acceptance test; foam concentrate sampling and laboratory analysis to the standard’s quality criteria; valve, flow and trip test records; and a deficiency list with recommended remedial priority.
An NFPA 25 programme is only worth what its records prove — see what the law requires and what NFPA 25 actually checks.
Why SATU
One partner from study to system: assessment → design → equipment supply → installation → commissioning → testing → NFPA 25 inspection and maintenance. Thai-speaking engineers, international standards (NFPA · IEC · API), equipment from world-class manufacturers (FireDos, Solberg, Viking, Hydrauvision) — and where you need a fully independent study, we offer study-only engagements with no supply interest.
