    It flags version-to-version changes up front, which is helpful, but module 3 dragged and repeated basic definitions longer than needed. After that, it got practical fast. The walkthrough of Rule 18 with the brake interlock example stuck; seeing the exact wording tied to a roadside check made it click. Annexure 7’s placarding table was another useful stop—clear enough to turn into an ops checklist without guesswork. As a freelancer bouncing between clients, I care about fewer surprises in prod ops, and this maps rules to what inspectors actually ask. It’s simple, but not careless. I’ve already gone back a couple times to re-read the emergency response steps and valve isolation notes.

    Came in wanting a clearer picture of how the moving parts actually fit when hauling bulk LPG under SMPV. The walk-through of Rule 19 pre-trip checks and the clip showing excess flow valve behavior during a hose rupture stuck. Framing safety like arch/infra helped—think CI gates before prod, placarding as obs, and RPS as tanker throughput limits. Wasn't sold on the thin coverage of mock drills, but it's still time well spent even if you've shipped stuff in prod for years.

Course details

Increase awareness about importance of safety features and rules related to LPG road transport, consequences if not implemented properly and safe practices 

For inland transportation of LPG in bulk, road transport is the most convenient "Last mile coverage" method. Hence, thousands of Tank Trucks (TT) - (Road tankers) are criss-crossing the roads all over the world. Same is the picture in India. Highways, small town roads, hilly areas, ghats, forests, hot and cold regions .... You will see them everywhere. Public sector OMCs and Hundreds of private transport companies own these TT. Thousands of truck operators and their assistants earn their bread and butter doing this job. Many times, they travel in night and take rest in the day, depending on ambient temperatures.

Though statistics showing how many TT are being operated in India currently, could not be found, according to one website,  during 2013 to 2018,in India, Govt OMCs hired services of 19000 TT, and 24000 TT during 2019 to 2023.

LPG being highly inflammable, every TT is a travelling bomb, capable of creating hazardous situation in few kilometers area surrounding that spot. Though we often hear news about accidents involving TT or tanker carrying other hazardous fluid, the number is small percentage of the  number TTs on the road.

How is this possible?

This is possible because every country has developed stringent rules and regulations for controlling the activities related to LPG road transport, and also the strict implementation of the same. In India, PESO has assumed the role of controller, under the stewardship of Chief Controller of Explosives (CCOE). Rules with title "Static and Mobile Pressure Vessel rules (SMPV rules)" is the rulebook for this.

For anyone, working in this industry, in any capacity, at any stage from design of TT to final LPG delivery to end user, it is essential to know sufficiently, the rules; and thoroughly understand the principles involved in that particular rule. This will ensure proper implementation and enhanced safety.

This course is an effort towards acquainting the participants with the rules and more importantly, explaining the principles underlying the rule.

Who will benefit by this course ---

This course will be useful for everyone, in LPG transport business --- TT owners and their technical staff, truck operators, storage plant operation and maintenance personnel, TT designers, manufacturers.

Came in expecting something closer to prod patterns, and it mostly met that bar for an oilgas context. The section on the LPG bottling plant walkthrough, especially the cylinder tracking flow and where audits break, stuck because it maps cleanly to arch and infra tradeoffs we argue about in PRs. I wasn't sold on the market sizing chapter; felt thin and light on obs metrics or RPS-style thinking. Still, it's given me better ammo for the conversations that actually matter with ops and product.

Module 2’s bottling-plant capex spreadsheet and the propane vs butane pricing parity example stuck, since it's mapping classroom math to day-one ops in oilgas LPG. mostly useful, though I wasn't sold on the light treatment of safety regs and wished there was more on distribution infra beyond cylinders.

Felt closer to a mentor’s whiteboard than a packaged class, especially in how it bridges legacy LPG ops with more modern thinking. Chapter 3’s bottling-plant cashflow example, where he maps cylinder recert delays to dealer churn, stuck; it’s the kind of prod reality you don’t see in decks. i've been translating some of that into how we think about arch and infra, even borrowing obs/RPS framing without pretending LPG runs like k8s. Mostly worked, though I wasn’t sold on the light touch around digital reporting, but the failure-mode framing made the time count.

Chapter on mass vs volume at 15°C with the butane example—it's mostly useful, wished more on custody transfer math.

Questions and Answers

A: IS 2062 carbon steel appears ordinary, which makes it easy to doubt under coastal service, but SMPV assumes dry LPG and manages external corrosion by coating and inspection, not exotic metallurgy. Stainless sounds attractive, yet chloride stress cracking under road salt and cost make it a poor fit. Low alloy steel adds strength, not meaningful corrosion resistance in this exposure. Epoxy linings solve liquid corrosion problems you don't actually have with dry LPG and introduce lining failure risk.

A: Excess flow valves need a high flow rate to trip, so a slow seep looks harmless to them. Hose rupture and drive-away both generate the surge the valve is meant to sense. Mechanical damage that opens the line fast enough also triggers closure. The subtle failure is the one that never reaches the set differential.

A: Solar heat on a full tanker with little vapour space drives liquid expansion fast, which is exactly the scenario SMPV fears. Vapour return issues matter during transfer, not static parking. Residual nitrogen would show up as higher starting pressure, not a slow climb. A bad gauge explains the reading, not the thermodynamic behaviour observed.

A: Fire exposure is the design basis SMPV keeps coming back to, and secondary metal sealing is what survives it. Soft seats seal well until they burn. Gate valves give indication but are slow and bulky for emergency isolation. Butterfly valves are fine elsewhere, but not as primary TT isolation under SMPV expectations.
