Pile Driving Part III: Installation Equipment — Pile Buck Magazine

View Part II of this article here. Over time, the technology for pile installation has led to the development of hammers that are both larger and faster. From rams that were raised by humans or horses to steam, air, and hydraulic hammers to double acting hammers, this equipment is an essential part of any construction… via … Continue reading Pile Driving Part III: Installation Equipment — Pile Buck Magazine

No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

There's an urban legend going around social media these days that states that the "demise" (which is hardly true since they're still in use) of air hammers is due to the fact that the valve admits air to the cylinder before impact, thus slowing down the ram.  This legend has it that this was detected … Continue reading No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

OTC 5397 Revisited: Analysis of Cushioned Pile Hammers

This is a new paper to update and expand on part of the first technical paper presented by a Vulcan employee: the paper "A Proposal for a Simplified Model for the Determination of Dynamic Loads and Stresses During Pile Driving," originally presented at the 1987 Offshore Technology Conference.  The abstract is here: Warrington (1987) was … Continue reading OTC 5397 Revisited: Analysis of Cushioned Pile Hammers

China’s Historic Houston Consulate Gets the Boot, Goes Up in Flames

In the midst of the souring relationship between the two countries: Beijing vowed to retaliate after it said that the United States ordered its Houston consulate to be closed within 72 hours, calling it an “outrageous and unjustified move,” marking a serious escalation in the quickly deteriorating relationship between the U.S. and China... The announcement … Continue reading China’s Historic Houston Consulate Gets the Boot, Goes Up in Flames

Chabahar: a Vulcan “Almost” Becomes a Point of Contention with the Suez Canal

The Iranians want to bypass the Suez Canal using their port at Chabahar: The Iranian Chabahar Free Trade Zone Organization announced July 5 that trade connections to Mumbai, Hamburg and St. Petersburg will be made through Astrakhan (in Russia), Anzali and Chabahar (in Iran) and Nhava Sheva (in India) instead of the Suez Canal. This raises questions … Continue reading Chabahar: a Vulcan “Almost” Becomes a Point of Contention with the Suez Canal

The Limitations of Dynamic Formulae

In an earlier post Vulcan's advice on the limitations of dynamic formulae--specifically referencing the Engineering News Formula--was set forth.  That advice appeared in Vulcan's literature from 1906 to 1931.  Later in the 1930's Vulcan changed the way its literature was organised, and in the process Vulcan added new verbiage (a lot of it, really) to … Continue reading The Limitations of Dynamic Formulae
