Sealing system keeps tunnel industry digging

Tunnels are getting larger, deeper, and excavated in more challenging conditions. There is also growing pressure to successfully complete these projects while meeting increasing demands for performance, on-schedule delivery, and safety. However, on many projects, concrete tunnel segments are fitted with rubber gaskets onsite and secured using adhesive, which can lead to time-consuming and cost-intensive

LVDT sensor for use on subsea trees

Back in 2010, Deepwater Horizon suffered a major blowout of its oil-drilling platform. Analysis revealed that part of the cause was a failure of the blind shear ram to properly cut the drill pipe and seal the wellbore. But the failure of other components to operate as designed also poses environ-mental risks. For example, failure
