OceanGate Titan

A young company pushing to re-invent deep sea exploration with an initial focus on opening up tourism to the wreck of the Titanic, OceanGate garnered the fascination of many around the world. With a different approach to their hull design they forged ahead despite many warnings from experts in the field, concerned about their design decisions and materials choices. When the submersible imploded killing all five aboard including the company CEO, the experts were only surprised about how OceanGate had got as far as they had...before it all went horribly wrong.With John Chidgey.Formal Reports: NTSB Final Report (PDF) US Coast Guard Marine Board of Investigation Final Report (PDF) General Information: OceanGate Titan Submersible Implosion Antipodes Oceangate Cyclops 1 (PDF) OceanGate founder looks beyond Titanic to new deep-sea frontiers The Titan Tragedy: A Deep Dive Into Carbon Fiber Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle, Kellen Frodelius-Fujimoto and Steve Branam.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.

West Gate Bridge

Planned for nearly a century, when the time came to build a permanent link across the Lower Yarra River, a relatively new style of bridge, the box-girder, was chosen. Using new computer technology assisting the engineers to design a bridge that was too complex to calculate by hand, and using a unique lifting strategy promised time and cost savings. Ultimately though when the pieces didn't fit together in the air, their attempts to make them fit, didn't work. We dive into what went wrong on Australia's largest ever industrial disaster.With John Chidgey.Formal Report: Victorian Royal Commission Report (PDF) Milford Haven Incident: Cleddau Bridge disaster General Information: Kentledge West Gate Tunnel Slide rule Box girder bridge Cleddau Bridge Widening the West Gate Freeway Melbourne October 15 Weather The West Gate Bridge Memorial Robbo Bennett’s Tribute How the West Gate Bridge collapse changed Melbourne 1970 West Gate Bridge Disaster West Gate Bridge Image Gallery The West Gate Bridge Collapse West Gate Bridge Under Construction, 1969 Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle, Kellen Frodelius-Fujimoto and Steve Branam.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.

West Fertilizer Company

In the early hours of the evening on the 17th of April, 2013 in the small city of West, Texas...smoke was seen emanating from the West Fertilizer Company building. In 20 minutes there was a massive explosion that levelled the facility and its surroundings, killing 15 people and injuring hundreds more. How this came to be, represented a failure of regulations, planning and grandfathering on every level.With John Chidgey.Related Episodes: Causality Episode 44: Warehouse 12 Formal Reports: Preliminary Findings Chemical Safety Board (PDF) Final Chemical Safety Board Report (PDF) West Fertilizer Explosion and Fire CSB releases final report on West, TX blast News Releases and Articles: Fire that led to Texas fertilizer-plant explosion was deliberately set West Texas Plant Explosion Regulations: Code of Practice: Safe storage of Solid Ammonium Nitrate (PDF) General Information: West Fertilizer Company Explosion West, Texas Polyolefin Asphalt Shingle Ammonium nitrate | H3N.HNO3 | CID 22985 - PubChem This Month in Fire History: April 2024 City of West to Receive $10.4 Million in Lawsuit Settlement Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle and Kellen Frodelius-Fujimoto.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.

737 MAX

With two crashes in five months of the new 737 4th Generation a design flaw seemed likely.

After an extended outage of the Methomyl Unit at the Bayer facility in Institute, West Virginia, the decision was made to commence a restart of the Unit even though the DCS upgrade was still incomplete and the newly replaced Residue Treater hadn't been fully recommissioned.

On the 20th of September, 2022 at the BP Husky Toledo refinery in Ohio, a level transmitter change out from a month prior triggered a chain of events that would cost two operators their lives.

737 MAX Ethiopian Air

Five months after Lion Air 610 crashed, another 737-MAX went down with a similar cause. However the official report was at odds with two other internationally respected investigative organisations. We dig into the detail of how the AOA Sensor was claimed to have failed, and review checklist discrepancies to extract fact from opinion as to what most likely triggered this horrible chain of events.With John Chidgey.This show is Podcasting 2.0 Enhanced Celebrating Causality’s 50th Episode!!

In 2017 during an Odoriser decontamination procedure in West Virginia, two people were killed when it unexpectedly exploded.

Callide C Blackout

In 2021 the Callide C Power Station experienced a unit failure that tore the turbine-generator apart, resulted in hundreds of thousands of premises losing power, and cost hundreds of millions to repair. We look at how design errors and ultimately a lack of information led to the incident escalating out of control, when it could have been recovered.With John Chidgey.Formal Reports: Callide Unit C4 Turbine Generator Failure 25 May 2021 (PDF) Animation of the Callide Unit C4 incident Trip of multiple generators and lines in Central Queensland and associated under-frequency load shedding on 25 May 2021 (PDF) News Releases and Articles: CS Energy releases report into 2021 Callide C4 Unit Failure CS Energy releases technical report into 2021 Unit C4 incident Dr Sean Brady to lead independent investigation into Callide incident Battery failure led to power plant mass outage Both units trip at Callide C on Wednesday 13th January 2021 Statement regarding IG Power Intergen voluntary administration Report says Callide C4 incident “could not have been anticipated” Callide explosion blamed on battery charger failure Callide Power Trading taken to court over system failure CS Energy says insurers won’t agree to $300m claim over power station Jim Soorley stands down from CS Energy CS Energy Post about Incident on LinkedIn Super-Critical Boilers: Super-Critical Boiler Technology (PDF) Supercritical Fluids Supercritical Coal Plants Electrical Engineering References: Hydrogen-cooled Turbo Generator Reverse Active Power Protection (ANSI 32P) Court Action: Alleged failure to obtain regulatory approval to operate a generating system Notice of Filing: Australian Energy Regulator v Callide Power Trading Pty Ltd (PDF) Coal generator to face court over blackouts caused by catastrophic explosion General Information: Callide Power Station Stanwell Power Station Tarong Power Station Callide Power Station CS Energy: Water Management NOTE: Minor Corrections in audio updated: 31st March, 2024 Support Causality on PatreonEpisode Gold Producers: 'r' and Steven Bridle.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Lesley, Jared Roman, Joel Maher, Katharina Will, Chad Juehring, Kellen Frodelius-Fujimoto and Ian Gallagher.

Carnival Triumph

A leaking flexible pipe started a fire in the Engine Room aboard the Carnival Triumph during its return journey from Mexico in early 2013. The fire caused minor damage in one, very important section of the Engine Room leading to a total loss of Mains Power. With only intermittent Emergency Power and over 4,000 people on board the ship drifted with the currents before it was tugged finally to safety. The Netflix Documentary 'Poop Cruise' looked at the human consequences...we dive into the engineering design that was inherently flawed from Day One.With John Chidgey.Formal Report: BMA Investigation Report (PDF) News Releases and Articles: Carnival Cruises issues statement Carnival Triumph set sail with problems Stricken cruise ship docks How Poop Cruise Crisis Reshaped Cruising General Information: Trainwreck Poop Cruise (Netflix) Failure Domain Cruise Lines International Association Understanding Cruise Passenger Rights Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle, Kellen Frodelius-Fujimoto and Steve Branam.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.
