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

Pros and Cons of Floating Platforms in Marine Renewable Energy

Are floating platforms the future of marine renewable energy? It’s hard to tell just yet. Floating platforms have been bulwarks of the oil and gas industries for decades. If we can use a floating platform to drill from the ocean surface down through kilometers of bedrock, how hard could it be to mount a wind… Read More

Environmental Concerns of Marine Energy

Generating electricity from waves or tides requires placing large mechanical devices in the middle of complex, fragile ecosystems. How will life respond to these intrusions? Because we’re so early in the evolution of marine energy, environmental concerns post a host of serious questions, such as: What have we learned from the development of artificial reefs?… Read More

Obstacles to Developing Marine Renewable Energy in the U.S.

In theory, thousands of miles of shoreline should make the United States an ideal locale for developing marine renewable energy. But tapping the energy from all the waves pounding the shores of the Atlantic, Pacific and Gulf coasts of the U.S., is an incredibly complex prospect. A wide range of obstacles must be overcome. Topographical… Read More

Market Opportunities Abound for Marine Energy Technology

Companies that feel like they’ve missed the boom in offshore wind power technology may have the chance to ride a new wave of innovation with the rise of marine energy technology. Converting the solar and kinetic power of our oceans into cheap, practical electricity seems like a far-off hope right now, but at some point… Read More

Four Methods of Marine Energy Conversion

Four intriguing technologies hold the potential to tap into the vast renewable energy of our oceans. Nobody expects these marine energy technologies to replace coal, petroleum or natural gas in the near future. Instead, they could become assets in a diverse portfolio of technologies that can reduce our dependence on fossil fuels and temper the… Read More

Challenges in the Installation and Repair of Marine Energy Devices

Turning our oceans into a reliable power source means putting complex devices in treacherous, ever-changing environments. The sea is much friendlier to sharks than to subsea power turbines. PMI has been providing cable hardware for oil exploration and other subsea projects for decades, so we know only too well the challenges of putting anything in… Read More

Six Obstacles to the Development and Commercialization of Marine Energy Devices

  Marine energy is a beguiling concept because our oceans have massive energy potential. Oceans can produce kinetic energy and store solar energy, both of which can be converted into electricity to replace fossil fuels that contribute to global warming. But surface water on our planet also produces significant challenges: it’s turbulent, corrosive and teeming… Read More

PMI Proud to Represent the U.S. at International Marine Energies Technology Course

It’s one thing to dream about the immense power residing in our planet’s oceans. It’s quite another to put human ingenuity to work tapping into the ocean’s powers. That was the backdrop of the International Marine Energies Technologies Course, held in mid-March in The Netherlands. Some of the best minds in marine energy technologies gave… Read More

How Robots are Fixing Damaged Subsea Cables

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