Why Synthetic Cable Terminations Are Unique

  Synthetic cable is stronger than steel on a strength-to-weight basis, which makes it an attractive option in marine environments. The key challenge of synthetic cable is what you do about the attachment points, or terminations. Terminations can cut the tensile strength of synthetic cable by more than 50 percent, potentially defeating the purpose of… Read More

Why Should You Consider Synthetic Cables for Your Marine Energy Project

Steel cables have unmatched strength and stability, which is why they’re so common in dry-land uses like elevators, construction cranes, and suspension bridges. But steel cables have troubles in marine environments: they rust, they sink, and they’re just hard to handle easily. Synthetic cables are showing up these days in a lot of marine engineering… Read More

Planning a Marine Energy Project: Cable Considerations

Whether marine energy project planners deploy wind, wave or tidal devices, they cannot afford to overlook the basics: transmitting power back to the mainland via electrical cables. There’s an abundant body of knowledge on transmitting electrical power via underwater cables because power companies have been doing it decades. Indeed, Europe’s mature offshore wind industry has amassed… Read More

Are Cable Issues Undermining Offshore Wind Success?

Offshore wind technology gets better every year with more innovative turbine and blade designs. But no matter how well they design a wind turbine, engineers perpetually confront the unique difficulties of exporting electricity back to shore. Subsea power cables are built with the demands of open ocean in mind. Multiple layers of alloy and fiber… Read More

Subsea Cable Trade Group Widens Focus to All of Europe

A trade association representing the subsea cable industry in the United Kingdom widened its focus in March 2016 to cover all of Europe. The new European Subsea Cables Association (ESCA) takes the place of Subsea Cables UK. The trade group provides a forum for people who own, manage or service subsea telecommunication and power cables… Read More

What kind of ocean equipment will be needed for subsea power grids?

Subsea power grids require two major kinds of ocean equipment: subsea power cables to convey electricity to the grids, and generating equipment to distribute electricity to pumps and other devices required to find and extract crude oil. Even in a time of depressed petroleum prices, oil companies still value deep ocean engineering and they like… Read More

How Robots are Fixing Damaged Subsea Cables

We have previously discussed the various ways subsea cables can be damaged underwater (Link: http://powerofpmi.com/damage-to-subsea-cables-a-huge-risk-to-offshore-wind-farms/), but how are these cables fixed? The answer lies on a ship like the Pierre de Fermat, a ship specially designed for undersea cable repairs.  Once the break location is identified, the ship launches a remotely operated vehicle (ROV) to retrieve… Read More

5 Reasons Why the EVERGRIP Is The Ideal Solution for Your ROV’s Subsea Cables

We’ve gone in depth before on how cable terminations are used , now we’re going to explain what sets our terminations apart from the competition. Many current terminations require an epoxy/polish method of installation. There are many disadvantages to using epoxy. If you’re using heat-cured epoxy, it takes a ½ to cure, but you need… Read More

How Deep Ocean Engineering Companies are Diversifying

As the energy market continues to turn away from oil and gas and towards renewable energy, many companies that specialize in deep ocean engineering, like PMI, are following suit. One company that has made great efforts to shift from oil and gas into the renewable energy field are the Norwegian subsea specialists Ocean Installer. The… Read More

Why the growing renewable energy market should be concerned about subsea cable vulnerability

As the world’s energy sources quickly shift towards renewables, wind farms are becoming a leading source of sustainable power. With many of these wind farms being located miles off shore, engineers depend on subsea cables to move power to and from the farms. When dealing with miles of cables, length, wear and tear, and improper… Read More
