Hurricanes, cold Waves, Tornadoes: Weather Disasters in USA dominate natural Disaster Losses in 2021

  • In 2021, natural disasters caused overall losses of US$ 280bn, of which roughly US$ 120bn were insured
  • Alongside 2005 and 2011, the year 2021 proved to be the second-costliest ever for the insurance sector (record year 2017: US$ 146bn, inflation-adjusted) – overall losses from natural disasters were the fourth-highest to date (record year 2011: US$ 355bn)
  • Hurricane Ida was the year’s costliest natural disaster, with overall losses of US$ 65bn (insured losses of US$ 36bn)
  • In Europe, flash floods after extreme rainfall caused losses of US$ 54bn (€46bn) – the costliest natural disaster on record in Germany
  • Many of the weather catastrophes fit in with the expected consequences of climate change, making greater loss preparedness and climate protection a matter of urgency

Robbins XRE TBM crosses the finish Line at Chile’s Los Condores HEPP


A Robbins 4.6 m (15.1 ft) diameter Crossover machine holed through in the Andes Mountains of Chile in the last quarter of 2021. The XRE TBM bored a 3.3 km (2.1 mi) long tunnel for Chile’s Los Condores Hydroelectric Power Project (HEPP) and project owner Enel.

A dedicated team, including three Robbins Field Service personnel, guided the machine to breakthrough in conditions including tuff, sandstone, breccia, and conglomerate with sections of high-pressure water inflows. Ground cover reached up to 450 m (nearly 1,500 ft) above the tunnel with rock strengths maxing out at 60 MPa UCS. “Robbins Field Service was an important part of the success of the excavation, evaluating continuous improvements in the machine and correcting faults,” said Ricardo Riveros Puratic, Project Engineer for Enel.

For Riveros Puratic, Crossover machines make sense despite the challenging conditions: “Towards the end, [the TBM] exceeded expectations. Crossover TBMs are suitable for Andean geology of sedimentary and volcanic type, where there is a great range of rock strengths and hydrogeological conditions.” Maximum advance rates topped out at 605.8 m (1,988 ft) in one month and 212.8 m (698.2 ft) in one week.

The Crossover machine featured a heavy duty, centrally mounted screw conveyor for the duration of the drive. The TBM remained in a hard rock configuration with muck chute installed, along with paddles, bucket lips, scrapers and disc cutters on the cutterhead. However, “75% of the excavation was performed using the main drive gearboxes in high torque configuration (EPB or low speed mode). We never physically changed the cutterhead or screw conveyor to EPB mode,” said Omar Alvarez, Robbins field service site manager at Los Condores.

High-pressure ground water inflows were the key challenge of the project. “When we started the excavation, we used dewatering hoses to reduce the water into the cutterhead during the excavation,” said Alvarez. Water pressures rose whenever the TBM stopped, however. “During the segment ring installation, we stopped the water from draining through the rear shield drilling ports and we closed the screw conveyor rear gate. We reached 7+ bar in the cutterhead earth sensors.”

“We bored in places with 5,500+ liters (1,500 gal) /min, making back-fill grout injection behind the concrete segments a challenge. We decided not to use the grout injection through the tail shield ports, but instead injected grout directly through the concrete segment with hoses. This approach was more flexible and reduced the need for reinjections,” said Alvarez.

With multiple triumphs and lessons learned during tunneling, Alvarez reflected on the breakthrough: “I’m proud to be part of a team that finished a tunnel in the Andes Mountains.” Once brought online, the Los Condores HEPP, located in the mountainous southern Maule region, will have an annual generating capacity of 150 MW.

How an IIoT Solution for Mining Machines can be successfully introduced into a Quarry OperationHow an IIoT Solution for Mining Machines can be successfully introduced into a Quarry Operation

Many mining companies still do not know whether they are ready to implement IIot projects for mobile mining machines – and things often stay this way until they try out digitalisation for themselves in an in-house pilot project. Sometimes it is enough simply to go for it and learn from the experience. But what is actually possible and how can ‘digital transformation’ be applied in-house? The conditions and measures needed for such a successful digital transformation are outlined below from the perspective of a tech company that supplies hardware and software solutions and also supports clients through the introduction and implementation process....
