Ongoing improvements in 3D printing are helping PMI explore new ways to provide engineered solutions that meet customer needs. PMI is improving quality control, prototyping crucial components, and experimenting with designs that will reduce assembly time by taking advantage of 3D printing’s additive manufacturing technology.
“The PMI engineering team has used additive manufacturing to make solid three-dimensional objects from a CAD (computer-aided design) file for several years. Because fabrication materials are improving and becoming more cost-effective, we are investigating more ways we can apply the technology,” says Terrence Mathis, PMI Manager, Engineering-Cable Protection.
Engineering team members are managing small projects to improve mold fabrication, potential part casting, compression dam manufacturing, and more.
Analyzing tolerances and variations to improve quality assurance
PMI is using 3D printing to test engineering tolerances of manufactured parts, such as plugs and rings used in a variety of applications. The time needed to measure internal and external features of parts, and ensure their proper fit, can add hours to the quality control process and affect product yields. Also, it can add time-consuming iterations to production if changes occur late in the design cycle.
“Some complex parts have over 20 features that can take four or more hours to inspect,” Mathis says. “Different tools may be needed to measure each section. Depending on the production quantity, it can add a lot of time. Through tolerance optimization, PMI has the potential to improve manufacturing time and reduce cost.”
Prototyping components that customers need to remain operational
PMI is using 3D printing capabilities to prototype crucial components, such as its precision precast compression dams used in DAM/BLOK™ electrical splice kits.
Many of PMI’s field-installable products incorporate helical gripping rods as part of the kit. At times, it is necessary to reterminate a PMI product—sometimes while out on the ocean–to replace helical rods affected by excessive corrosion, or to refurbish the cable connector.
PMI manufactures the DAM/BLOK™ electrical splice kit as a full-ocean depth pressure splice for cable connections. However, there are over 100 existing DAM/BLOK electrical splice kit designs, not including splice kits that can be custom designed for customers. Despite the degree of customization, each kit includes several crucial components, including precision precast compression dams.
Currently, PMI is testing compression dams to ensure it prevents outside seawater as well as leak water within the cable from passing through the splice to the electrical connection. This is especially important at increasing ocean depths.
Developing designs that reduce assembly time
PMI uses 3D printing to develop new standardized collar assemblies for its DYNA II cable hangers.
Customers who purchase PMI’s DYNA II cable hangers benefit from its tool-free installation and multiple degrees of freedom, which allow spreader rope loads to pass through with minimal effect on the lead-in and umbilical cables. Like many PMI products, DYNA II can be custom engineered into several configurable kits and accessories.
A collar assembly is just one of the components in a typical DYNA II configuration. PMI is using 3D printing to develop a new standardized collar to be used on legacy and new systems. The prototype collar is 3D printed in a wax resin, which is then cast in stainless steel. The collar serves a build-measure-learn function while saving tooling costs as PMI works to create an improved collar that benefits its customers.
Thinking outside the box to increase development speed
“Our customers turn to us for engineered solutions that include design, fabrication, and testing of subsea tow cables, hardware, assemblies, and protection,” Mathis says. “With a 3D printer, we’re able to take advantage in low-volume situations to revolutionize our development, design and replacement parts in ways that benefit our customers.”

For undergraduates from the Cleveland area, the Emerging Scholars Program offers a path to excellence
In the spring of 2011, a few weeks after he had accepted an offer of admission to Case Western Reserve, Terrence Mathis (CWR ‘16) opened a letter from a faculty member he had never met.
Stephen Haynesworth (GRS ‘87), an associate dean in the College of Arts and Sciences, had written to congratulate Mathis and assure him that he had made the right decision. “When we at CWRU admitted you to the university,” Haynesworth told him, “we demonstrated our respect for your achievements and our confidence that you can succeed here.”
Blog Summary:
- 80% of unexpected challenges and delays in marine projects is cable failure.
- Cable failure creates risks for losing expensive subsea equipment.
- Full-strength underwater cable terminations prevent cable failure during deployment and retrieval of subsea equipment.
- Unlike other helical terminations, PMI’s grips are built to hold your subsea cable to the full-rated breaking strength
- A benefit of the helical wire design permits easy installation of the termination anywhere along the length of the cable and does not require access to the cable end.
- Can be easy installation anywhere along the length of the cable and anywhere in the field.
- Do not require tools or cable preparation.
More subsea projects are happening than ever before, and ROVs, side-scan sonars, and other offshore equipment are almost always an element within them.
When equipment like ROVs and side-scan sonars are deployed or received, the twisting and bending of the cable at the termination point is common. Side-scan sonars and ROVs need these cables to stay intact and be able to bear the weight of the equipment. If these cables can’t keep up, it will cost serious delay and expense to projects.
Cable failure is the cause of 80% of unexpected challenges and delays.
The most common instance happens when subsea equipment is deployed from a vessel or retrieved from the sea and fails due to an extreme amount of tension being placed on the attached subsea cables. If these delicate cables are not terminated properly, they experience damage from strumming and snap loading. At this point, your crew can find themselves spending a good day starting over with installing a brand new termination – costing your project valuable time and money.
Without a proper underwater cable termination or grip, all of the stress and tension is concentrated along the cable where it is attached to the equipment. This is a ton of localized stress on what is usually a very expensive mechanical, electrical, or optical cable. Without a full-rated strength termination, you could be creating a recipe for disaster – cable damage, or worse, a cable break that results in the loss of expensive equipment.
How Helical Terminations Prevent Cable Damage
Helical terminations are designed to function similarly to a Chinese finger trap — a childhood toy that is a woven paper tube letting you place a finger into each end, and then, as you try to pull your fingers out, the tube tightens around your fingers. The harder you try to pull, the tighter the tube grasps your fingers, creating a secure hold.
Helical terminations work the same way. Helical rods are wrapped around the subsea cable at the termination location of the undersea equipment. With a helical termination, all of the stresses that would occur at one localized point on the cable are spread out over the length of the cable wrapped with the helical rods; therefore, greatly reducing the stress on any specific location of the cable.
To be technical, axial loading, a force that passes through the center of an object, causes elongation of the helix (or cable) and results in radial contraction. This compressive force gives the helical rods its ability to hold force. If you hold one end of the helical rod and attempt to pull the cable out, you transfer the load from the cable to the helical rods.
If at any point the load increases, the holding force increases. This mechanism provides a gradual transition of the load from the cable into the helical rod until the helical rods carry the full axial load.
Creating Reliable Attachment Points
A benefit of the helical wire design permits easy installation of the termination anywhere along the length of the cable and does not require access to the cable end. Many times attachment points are needed along the length of the cable. A good example of this is for creating an attachment point for the cable to be lifted from the seabed.
Why PMI’s Helical CABLE-GRIP™ and STOPPER-GRIP™ Terminations are a Preferred Choice
Unlike other helical terminations, PMI’s grips are built to hold your subsea cable to the full-rated breaking strength. When you are working with some of the most advanced and extremely expensive machinery in the industry, you can be confident that PMI’s equipment protects yours better than any cable hardware on the market today.
PMI’s Helical Terminations:

With more than 95,000 miles of shoreline, the United States looks like an ideal candidate for offshore wind energy development. But it’s not that simple.
A substantial portion of U.S. shoreline tracks the Southern Atlantic states and the Gulf of Mexico, where the winds are either too weak most of the year or potentially catastrophic during hurricane season. The Pacific Coast has steady, powerful winds, but the continental shelf drops off sharply near the shore, requiring floating wind-power platforms that cost much more than fixed-position wind farms.
The economics of offshore wind present a second order of complexity. Offshore wind developers have to weigh factors including:
- Costs of competing energy sources like coal and natural gas
- Population density of the area using the power
- Availability of subsidies and renewable energy credits
- Expense of designing, manufacturing, and deploying wind farms
An intriguing study from the Berkeley Lab’s Electricity Markets & Policy Group developed a series of models to compare the economic value of offshore energy projects along the Eastern Seaboard of the United States from 2007 to 2016:
“The market value of offshore wind between 2007-2016 varies significantly by project location and is highest for sites off of New York, Connecticut, Rhode Island, and Massachusetts,” the study found.
States with most promising developments
In a May 2018 article, POWER magazine listed the most promising states for offshore wind. That roundup included:
- Massachusetts. With the doomed Cape Wind project finally out of the picture, the prospects for other offshore power projects are improving. The state government has passed legislation targeting 1,600 MW of offshore wind power by June 30, 2027. The law requires a buffer of 10 miles between offshore wind farms and inhabited areas to avoid angering the public, which prizes its coastal views. Three companies are bidding for projects off Martha’s Vineyard.
- Maryland. Two companies have been awarded renewable energy credits to develop wind farms of 120 MW and 248 MW. The credits are worth $3.6 billion over two decades. Developers are required to create nearly 5,000 jobs and invest in a steel fabrication plant and port upgrades. The project will involve 77 turbines from 12 to 21 miles offshore.
- New York. Gov. Andrew Cuomo would like to see 2,400 MW of offshore wind power developed in the next two decades. He wants to start with 800 MW in 2018-19.
- New Jersey. The state’s Offshore Wind Economic Development Act, passed in 2010, sets a goal of 3,500 MW of new power generation by 2030. The state’s Board of Public Utilities plans to solicit 1,100 MW of new projects, which would be the nation’s largest so far.
States and projects further down the coastline in Georgia and the Carolinas appear much less likely to bear fruit, the POWER magazine article explained.
Pacific Ocean possibilities
The Pacific Coast and the Hawaiian Islands each present intriguing opportunities because their terrain limitations require innovations in floating offshore platforms. Unlike Europe’s North Sea and the Eastern Seaboard of the United States, the shoreline of the Pacific plunges to depths that are impractical for the development of standard offshore wind turbines mounted on the seafloor.
In May 2018, the U.S. Navy complicated matters even further, stating that vast swaths of California coastline — including all of Southern California — should be off-limits to wind farms because the Navy needs that space for national defense purposes, the Los Angeles Times reported. The Navy cannot decide where wind farms will be deployed, but it has considerable influence.
Perhaps the best news for the Pacific comes from the coast of Scotland, where the first floating platform offshore wind farm is up and running. That wind farm is proving to be remarkably energy efficient, using up to 65% of its capacity factor, which is far better than land-based gas and coal power, according to Greentech Media. Capacity factor estimates a powerplant’s output as a percentage of its theoretical full energy output.
With the cost of developing offshore wind farms falling rapidly and floating platforms showing promise, power from the Pacific might be closer to reality than many observers suspect.
Great Lakes
A wind farm project in the works near our home base in Cleveland will test the viability of the Great Lakes, which have ample wind, high population densities, and relatively shallow water.
The Icebreaker project plans to deploy six turbines in Lake Erie about 8-10 miles northwest of Cleveland. Supporters hope this pilot project becomes a catalyst for further development throughout the Great Lakes.
Offshore wind is coming to U.S. shores
Many coastal states have ambitious renewable-energy goals that will require the development offshore wind because there’s only so much they can do with solar, land-based wind, and biofuels. Fortunately, they can benefit from decades of European experience in offshore wind combined with steep declines in development costs.
U.S. wind projects also raise the prospect of bringing good-paying jobs and economic development to communities that need a boost after declines in their manufacturing base.
As a manufacturer of premium cable accessories for offshore wind and other marine-energy projects, PMI is doing its part to support the industry and help reduce our reliance on fossil fuels. We believe the United States is ready for offshore wind, and judging from the volume of new projects in the pipeline, we’re not alone in that assessment.

The Cable Challenges of Saltwater vs. Freshwater for Offshore Wind Projects
The challenges of developing practical, economical offshore wind power are pushing engineers and entrepreneurs to new heights — and depths — of ingenuity.
We’ve talked about the pitfalls and potential of offshore wind and other marine renewables for years in our Ocean Engineering Blog. We’ve noted that it’ll never be easy to build technologies that must be submerged in corrosive, turbulent subsea environments. And marine-renewables will remain a tough sell as long as oil prices stay low.
But these challenges haven’t stifled innovation in the ocean-renewables sector, especially offshore wind. Here’s a look at some of the encouraging news we’re seeing:
Autonomous underwater and remote-operated vehicles (AUVs, ROVs)
The cost of deploying ships and divers to inspect, maintain, and repair cables and other subsea components has been a costly drag on offshore wind farms for decades. Widespread adoption of versatile, low-operating-cost AUVs and ROVs can reduce those costs substantially.
As we learned at Subsea Expo 2018 in Aberdeen, Scotland, companies developing advanced AUVs and ROVs are adding new capabilities that, for instance, add a cutting tool to an inspection AUV. Another promising development is underwater charging stations that allow subsea vehicles to roam free without cables. Instead, the stations themselves have cable connections to power sources.
Larger, more powerful turbines
GE Renewable Energy’s forthcoming Haliade-X 12-mw turbine underscores the drive to build ever-larger devices that produce more energy in a single tower. Billed as the most powerful turbine on the planet, the Haliade-X will be able to power 16,000 European households with a single turbine. That means a single wind farm of 50 towers could serve 800,000 households — potentially a city of more than 2 million people.
Standing 260 meters high with a 220-meter rotor, the Haliade-X will produce 45% more energy than any other turbine on the market, GE says. It’s expected to start showing up in wind farms in 2021. For more on the size challenges in offshore wind, see this profile of former Siemens CTO Henrik Stiesdal in Wind Power Monthly.
Floating platforms
The prospects for offshore wind farms on floating platforms got a boost in March 2018 when Statoil announced its new floating platform off the coast of Scotland reached a 65% capacity factor for November 2017 through January 2018 — besting a host of competing power sources. That news supports the principal rationale for floating platforms: deploying them farther from shore, where the winds are stronger and more consistent.
Capacity factor estimates a powerplant’s output as a percentage of its theoretical energy capacity. Greentech Media noted that U.S. onshore wind farms have a capacity factor of 37%, while coal- and gas-fired power plants have capacity factors of 54-55%.
Suction-bucket foundations
Floating platforms could be the future of offshore wind, but most projects in the next few years will keep using towers anchored to the seabed. Current anchoring methods create an abundance of noise, disturbing sea life and generating concerns about the environmental impact of offshore installations.
A new alternative is the suction-bucket foundation, which uses a base shaped like an inverted bucket. It works like this: After the bucket settles on the seafloor, operators pump out all the water inside it, creating a pressure differential that helps fix the bucket in place. When it’s time to decommission the bucket, water can be poured back into it. The first commercial-scale suction-bucket foundation in a wind farm was installed earlier this year off the coast of Scotland, Powermag.com reported.
Research updates
Here’s a look at recent research in the offshore-wind sector:
- Seabird avoidance. Seabirds have little trouble avoiding the spinning blades of offshore-wind turbines, a new study finds. Windpower Engineering & Development summarized results of the Bird Collision Avoidance Study, which used video cameras and high-tech sensors to track bird movements around a working wind farm in the English Channel. The study analyzed more than 600,000 videos monitoring activity at the wind farm. Of those, about 12,000 showed bird activity. Notably, the videos captured a scant six collisions over the course of the study.
- Anti-corrosion studies. Offshore Wind Journal reviews reports pointing to potential solutions to the nagging problem of corrosion in subsea environments. The reports estimated that reducing corrosion could generate savings in the tens of billions of dollars throughout the ocean-renewables sector over the next three decades.
Offshore wind keeps showing more promise
These updates offer just a glimpse of the encouraging developments in the offshore-wind sector. As turbines grow more powerful and engineers figure out new ways to reduce costs and protect subsea ecosystems, it will become ever more realistic to depict offshore wind as an experimental power source with mainstream potential.

Pros and Cons of Floating Platforms in Marine Renewable Energy
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 industry has traditionally avoided ice-prone regions. Most new oceanic wind farms can tap decades of knowledge gleaned from the maturation of Northern Europe’s offshore wind industry.
That’s not exactly the case for projects in water that freezes every year. The first wind farm designed specifically to cope with ice opened off the west coast of Finland in the autumn of 2017. The 42-megawatt Tahkoluoto wind farm relies on gravity-based foundations that are tapered at water level to resist friction with ice.
Ice and subsea cables
Reports on the Finnish wind farm have mentioned the tower base design but haven’t delved into the implications for subsea cables. We’re not privy to the technical specifications of the project’s subsea cables, but we can offer a few insights based on our decades of experience with subsea cables in harsh environments:
- The extreme weight and mass of ice place relentless pressure on anything in its way. Wind farms on the Great Lakes have to be designed with these risks in mind, laying cables strategically to keep them away from ice flows and buildups. The inherently unpredictable nature of weather and the motion of ice could conceivably surprise wind farm developers.
- Winter repairs will be extremely complicated. It’s difficult enough to send a ship to the site of a cable break in the open sea — it can take weeks or months to get a crew to the site, fetch the cable, repair it, and return it to the seabed. Imagine attempting repairs in the winter in the Great Lakes where variable weather changes the ice thickness constantly.
Engineers can design for the most likely scenarios for subsea cables, but there’s nothing like real life to teach us lessons we couldn’t foresee with ice and wind farms.
The value of wind farms in icy locales
The abundance of strong winds across the Great Lakes creates opportunities to develop new technologies and engineer novel solutions to icy problems. As ice resides along Arctic coastlines, wind farm developments could bring clean power to remote communities that otherwise depend on fossil fuels for heating and light.
However, we can only figure out so much of what is on the drawing board. To understand the depth of the challenges of ice in offshore wind, people need to build wind farms and learn the lessons nature inevitably provides.
At PMI, we look forward to engineering rugged, high-performance subsea cable accessories that will be critical to the success of wind power in the Great Lakes and beyond.
