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 an oven to cure it. Room temperature epoxy doesn’t need a special oven, but the cure time can be 2-3 hours or more. When researchers are spending days or weeks out on the ocean gathering information, time is of the essence.
Other terminations on the market don’t use epoxy, but require specialized equipment to install or require extensive cable preparation before installation. In addition, many epoxy-less terminations have a higher connector cost.
PMI provides quality epoxy-less terminations for your ROV needs. Here are 5 that the EVERGRIP Helical Gripping Termination is your ideal solution:
- Faster Installation
The EVERGRIP termination is field installable and easily applied – usually in 30 minutes or less.
- No Special Tools Needed
Our product requires no additional tools or cable preparation to install
- Less Down Time
With the EVERGRIP, there is no need to wait for a termination/retermination to cure.
- Strain Relief for Cables
The special helical rod design relieves strain from the cable. We also have BSR solutions for additional strain relief to prolong cable integrity.
- Reuseable
The housing of EVERGRIP can be used – a Retermination Kit comes at a much lower cost than purchasing a new termination
As new challenges are placed on the ROV industry, PMI continues to provide new solutions to meet those challenges. Whether it’s greater strain capabilities, faster installation or higher cost savings, PMI has the capability to develop and supply the highest quality and reliability solutions.

7 Questions You Should Be Asking About Your Subsea Terminations
Any young, new industry will have growing pains, and the offshore wind farm industry is no different. Among other issues with offshore wind farms, one of the biggest problems to affect the industry are issues with subsea cables. Failures and issues during installation and maintenance of subsea cables have cost companies millions of dollars and have caused many delays in this new and quickly rising industry.
While much information on cable issues is closely guarded, there have been some high profile cases as well as some studies done regarding damage to offshore wind farms. One of these studies, conducted by the Bureau of Safety and Environmental Enforcement (BSEE), partially delves into issues specific to subsea cables. Failure statistics have shown that third party mechanical damage to cables is three to five times more likely that the risk of internal cable failures. A few examples of third-party subsea cable damage include:
- Jackup “Jacked Up” On a Cable:
One issue is the risk of Jackups “Jacking Up” on a cable. A Jackup is a floating barge fitted with long support legs that can be raised or lowered to service oil and gas platforms or wind turbines. According to the study by the BSEE, there have been issues with cables getting caught in the jackup and being damaged in the equipment.
- Anchors Damage To Cable:
Another common issue is damage from third party anchors. Often times, anchors of laying vessels will tangle with the cable being laid and cause damage to the cable.
- Cable Kinked
Perhaps one of the most common issues with subsea cables is their tendency to kink or bend. It is very easy to get a kink into the line when preparing to install cables and unkinking is a major exercise requiring special skills.
In addition to these issues, other common problems to cable installation can include: damage to cable during installation, weather or soil-related damage, cable or joint failure, or sediment movement that can lead to cable exposure.
Subsea cables are complicated pieces of equipment and need to be handled with care and should only be used with only the best cable hardware to promote longevity and fortification. PMI is ready to equip your cables with the highest quality cable hardware.

The shift towards sustainable and renewable energy sources has made a real change in the energy industry. As we previously reported on our blog, Europe and Asia lead in wind energy production globally – Denmark itself uses wind power for almost 40% of Danish domestic electricity. The United States continues to grow in the market as well, with the U.S. Department of Energy reporting that by 2030, wind power could supply 20% of all U.S. electricity. However, as more wind turbines are being created, the more people are beginning to speak up about them being an eyesore. The solution? Offshore wind farms.
Offshore wind farming has proven to be a successful solution, not just for eyesore issues, but for productivity. Outside of populated areas and buildings, wind blows more steadily over the water, thus creating more energy for consumption. Moreover, studies are being done to use wind farms to temper violent hurricanes and other large scale weather incidents that can cause devastation.

Despite all these solid moves in the right direction, offshore wind is still a new and growing industry. Carrying power to and from wind turbines miles out in the ocean requires proven subsea hardware and cables. PMI’s years of experience and knowledge of subsea conditions and high quality equipment is the solution to many problems that can develop in the harsh waters off shore. PMI is ready to help your company solve your subsea cable and engineering issues. Contact us today to schedule an appointment to talk to our experts.
Offshore wind and solar energy have been getting all the attention in the quickly growing renewable energy industry, but there’s another player that is beginning to grow strength in the energy market – ocean waves and tidal currents, or “marine energy”. There are vast amounts of energy that are produced within the moving waters of oceans and rivers, and companies working to harness this energy are quickly gaining speed.
While not nearly as large as the main competitors in renewables, marine energy has strong advocates and is quickly gaining steam in the renewable market. About 30 tidal and 45 wave energy companies are at an advanced stage of technological development. One of the biggest issues these companies are facing that has impeded forward movement in the market is the harsh ocean environments – the same thing that makes the industry work in the first place.
The intensity of sea waves is greatly unpredictable and can cause damage throughout the process. Installation of the equipment is often difficult – the areas that are best suited to harness wave and tidal energy are often very hazardous and can be difficult to navigate. As we mentioned in our article on subsea cable vulnerability, subsea cables and hardware have to withstand 14.5 psi per every 10.05 meters they are lowered into the ocean. That coupled with the harsh environment that marine energy succeeds in, makes for a harsh environment for equipment.
PMI has many years of experience engineering proven subsea hardware for companies around the globe. We are excited to be part of the quickly growing marine energy market and are ready to create custom and quality solutions that will withstand harsh and hazardous environments.

The outcome of your project will rely on the quality of your subsea terminations. Make sure to download our guide – 7 Questions You Should Be Asking About Your Subsea Terminations – for a through breakdown of what you should be looking for in your subsea terminations.
We’re excited for the coming year, and to share the enthusiasm and high expectations among industry leaders for steady growth in 2016. RenewableUK, a trade association for wind and marine energy, predicts a busy year ahead for the wind industry. We couldn’t agree more, with over 50 onshore wind projects, and an additional six offshore projects, scheduled to become fully operational in 2016 in the UK alone! That’s more than three times the capacity installed in the UK during 2015. And construction on another five offshore wind projects will begin there during 2016.
These projects will surely bring billions of pounds of investment to British companies across the supply chain and will support nearly 35,000 jobs.
As the wind industry grows, so do the risks. With rapid growth, the need for dependable offshore engineering solutions is imperative. Why? Because one small setback, like damaging a cable during installation, could put an entire wind farm out of service for months and lead to damage to turbine equipment, too. A study done by the Bureau of Safety and Environmental Enforcement on Offshore Electrical Cable Burial for Wind Farms estimates that 70% of insurance claims for offshore wind farms come from some kind of damage or breakage to the subsea cables.
And a subsea cable isn’t a quick fix either. A typical subsea cable repair equals several days for the ship to reach fault position. It’s 3-5 days once the ship is on site, and even longer if bad weather is involved.
PMI has years of experience in the offshore industries and continues to develop innovative hardware solutions for subsea cables.

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 company’s advanced vessel, the Normand Vision, was used for work on subsea umbilicals, risers and flowlines (SURF) for major companies in the oil industry. Realizing that their subsea construction support equipment could also be used to work on the underwater cables that connect offshore wind platforms with the power grid, the Normand Vision began working with wind farms, including Germany’s Gode Wind 1 farm. Ocean Installer is not the only subsea construction company to jump on the renewable energy bandwagon. Singapore’s EMAS has also begun adding wind energy projects to their portfolio.
PMI shares the vision of these companies as our energy markets focus on new horizons and is excited to work with customers to solve their cable issues with budget friendly and top quality underwater cable hardware that will maintain cable integrity in every kind of underwater environment.
