Titan’s carbon fibre structural issues explained

Published

on

A structural problem with the Titan sub’s hull could have led to the “catastrophic implosion” that destroyed the vessel and killed all five people aboard, experts say.

OceanGate-owned submersible fell apart as it descended toward the Titanic wreckage this week, and investigators were looking for clues on Friday.

The cause of the deep-sea disaster is still unclear, but one expert believes the sub’s hull – its main body – may have failed.

According to Virginia Tech ocean engineering professor Stefano Brizzolara, the sub’s pressure hull may have fractured under pressure and caused the implosion.

“It is difficult to say what caused the structural failure in this case, but any small material and geometric imperfection, misalignment of connection flanges, tightening torque of bolted connection may have started the structural collapse,” Brizzolara said.

There were two different materials used to construct the Titan’s hull: carbon fiber-reinforced plastic and titanium.

When it fails, the carbon fiber element can break into small fragments, as it is “very prone to possible defects” and “has a more fragile behavior” than other materials.

Titan’s repeated voyages to the wreckage of the ocean liner may have also caused the hull to deform and shrink.

“These repeated deformation cycles may have started some material defects in the [carbon reinforced plastic] or some permanent deformations or misalignment between the two parts of the hull that were built with two different materials, which deform in a different way,” he said.

When the implosion occurred, any small leak at that depth would have sent water rushing in at a speed of about 1,000 km (621 miles) per hour, Brizzolara said.

In Short:
– Police seek former protection officers of Prince Andrew for info on alleged Epstein-related offences.
– Authorities consider removing Mountbatten-Windsor from royal succession after investigation conclusions.
British police are reaching out to former protection officers of Prince Andrew Mountbatten-Windsor following his recent arrest related to allegations of misconduct in a public office.
The police have urged anyone with information about potential sex offences connected to Jeffrey Epstein to come forward.Authorities are considering legislative measures to remove Mountbatten-Windsor from the royal succession line once the investigation concludes. Any changes would require consultation with other realms where King Charles is head of state.

The recent allegations stem from claims that Mountbatten-Windsor shared confidential government documents with Epstein during his time as a trade envoy. The London Metropolitan Police is now identifying former officers who may assist in the ongoing investigation and has encouraged them to share any pertinent information.

Mountbatten-Windsor has denied wrongdoing in the Epstein matter.

In 2022, he settled a civil lawsuit filed in the U.S. by Virginia Giuffre, who accused him of sexual abuse. Reports indicated he paid her approximately £12 million, a claim he denies.

Police Investigation

London authorities are reassessing previous decisions not to pursue criminal investigations related to Epstein’s activities.

Recent document releases from the U.S. government have prompted police to explore allegations of human trafficking involving Epstein at UK airports.

Police have been actively searching Mountbatten-Windsor’s residences as part of their investigation. His arrest marks an unprecedented event in modern royal history, raising significant public interest and concern in various countries.

In Short:
– The U.S. Supreme Court has ruled that Trump lacks authority for tariffs without Congress support.
– Over 1,000 refund lawsuits from importers complicate the tariff issue, particularly for smaller businesses.
The U.S. Supreme Court has ruled against President Donald Trump’s tariff policies, stating he lacks the authority to impose tariffs without clear congressional support. Trump expressed disappointment and plans to implement a new 10% global tariff under different legal provisions.
Economists estimate more than $175 billion is at risk of refunds related to previously established tariffs, with potential litigations expected to last several years.Trump’s administration faces over 1,000 refund lawsuits from importers in the Court of International Trade, which ruled it can grant refunds to affected businesses. Each importer may need to pursue individual lawsuits, complicating the process, especially for smaller businesses that could find the financial burden prohibitive.

Learning Resources Inc., a toy company led by Rick Woldenberg, has contested these tariffs, potentially qualifying for refunds. Woldenberg hopes the Supreme Court ruling will initiate reflection on necessary economic adjustments.

Economic Impact

Economists suggest consumers may not notice significant changes due to persistent tariffs on numerous products. U.S. Treasury estimates predict the deputy’s revenue will remain largely unchanged despite Trump’s new plans to increase tariffs through other channels, specifically under Sections 122 and 301 of the Trade Act.

Trump’s forthcoming address to Congress is expected to address the implications of this ruling, which notably undermines a fundamental aspect of his trade agenda.

Despite past assurances regarding reform, uncertainties remain for both businesses and consumers as the administration explores future tariff strategies.

Bill Gates withdraws from India’s AI Impact Summit amid renewed scrutiny over past ties to Jeffrey Epstein.

Bill Gates has withdrawn from India’s AI Impact Summit just hours before his keynote, as scrutiny grows over his past ties to Jeffrey Epstein following the release of US Justice Department emails.

The summit has faced criticism over organisational issues and traffic disruptions, drawing attention away from its mission. Despite the chaos, it has secured over $200 billion in investment commitments, including a major pledge from Reliance Industries.

Indian Prime Minister Narendra Modi used the platform to stress the importance of protecting children in the rapidly evolving world of AI.
