Out of the Vortex

Vortex-induced vibrations (VIVs) have been known for at least five hundred years. For most of that time, VIVs were known as sources of destruction of aquatic structures, for example the apparent self-destruction of the Tacoma Narrows Bridge in 1940. This article describes a technique for harnessing usable electrical energy from a VIV-based electrical generator, VIVACE, positioned in waterways.

Dealing with
Icy Challenges

The challenges of building in ice are great and varied. The material can find the natural frequency of any structure built in it, and it's a constant battle to keep it from blocking access. Walter Kuehnlein, of consulting engineering firm Sea2Ice, can help solve some of these problems. But his most important piece of advice is that companies that want to build in ice should be rethinking the very idea of what it means to engineer.

The Mechanics of Ice: Developing Design Standards

The Mechanics of Ice: Developing Design Standards

Much has been learned about the mechanics of ice, including what happens at the microstructure level when icebergs collide with structures at sea. How ice fails under impact has been the subject of much research. Years of world-wide collaboration has resulted in a new ISO standard for designing offshore structures in Arctic environments.

Offshore Mechanics and Arctic Engineering deals with exploration, design, construction, and operations for oil, gas, and other natural resources offshore, especially in risky Arctic and subarctic regions. Climate and geology require highly specialized knowledge to manage drilling rigs and production platforms, whether floating or anchored, and ocean floor pipeline networks. Engineers need skills in wave dynamics, heat transfer, the physical properties of frozen ground and water, safety, and environmental protection.
