The PMI team had a good week attending the recent International Partnering Forum for Offshore Wind in Princeton, NJ. The exhibit hall, networking opportunities, and especially the B2B meetings with supply chain partners were great opportunities to meet with other developers, cable manufacturers, contractors, and installers. While this conference doesn’t have as much of an… Read More

The Oceanology International conference covers such a wide range of industries, all with the common mission of measuring, developing, protecting, or operating in the world’s oceans, providing lots of room for potential collaborations and idea sharing among market leaders. Being a conference with numerous offshore/subsea market leaders in attendance, it provides an opportunity for attendees… Read More

Ice hasn’t necessarily put a chill on the development of offshore wind in the Great Lakes of North America, but it does pose a significant challenge — both in the design of offshore wind turbines and the maintenance of subsea power transmission cables. Winter is a wildcard for the Great Lakes because the offshore wind… Read More

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

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

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

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

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

We have previously discussed the various ways subsea cables can be damaged underwater (Link: https://pmiind.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

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
