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
When laying and retrieving submarine cables on the seabed, or performing a cable pull from a vessel to an offshore wind platform, it is often necessary to hold a cable end onboard for up to seven days.
Cables must be anchored firmly onboard to keep them in place, and this anchoring is normally done by means of a cable stopper.
The cable left hanging in the ocean can be exposed to forces so strong there is a distinct possibility of becoming overtensioned. Meanwhile, the vessel’s crew works to keep station by the use of thrusters. If overwhelmed by winds, strong currents and waves, the ship can be driven out of position. The cable left hanging may end up acting as an anchor chain, subject to additional forces and tension.
In these situations, when the wrong cable hardware is used, or is installed incorrectly, the grip of cable tensioners can slip. The heavy cable starts moving unfastened, which is extremely dangerous for the crew, equipment and the vessel.
While the oil, gas and seismic industries have had plenty of experience with these issues, the growing offshore renewable energy companies are looking to manufacturers like PMI Industries for proven experience and products to guide the way.
Engineers who have made the leap from offshore oil to offshore renewable energy have worked with PMI’s products, such as our CABLE-GRIP™ and STOPPER-GRIP™ Terminations, and have found them preferable to typical braided cable grips or cable socks. These terminations are quick and easy to install, robust, and recommended by many cable deck crews.
Our unique cable grips are fully capable of holding cables to the rated breaking strength. Tensile load is transferred gradually from cable to termination with no stress or damage to the cable. And unlike braided stoppers, the helical termination wire design permits installation anywhere along the length of the subsea cable, since it does not require access to the cable end.
7 Questions You Should Be Asking About Your Subsea Terminations
As we find our products being used more and more for shipwreck explorations, we were really excited to read about this one nearly in our backyard in Lake Michigan and learning that there are many more to discover.
The bottom of Lake Michigan is literally a graveyard of shipwrecks. Local maritime historians say 1,200 of the 2,000 sunken vessels in Lake Michigan no longer exist because they hit shore and broke apart.
Experts add that about 360 wrecks have been found in the lake’s deeper water, but there are still many wrecks out there that remain undiscovered. Read more…
Scientists and researchers are tackling HABs in Lake Erie, which have depleted the oxygen from the deeper waters off Cleveland. PMI specializes in producing some of the heavy-duty equipment being deployed in order to solve this problem.
The season of algal blooms — the green slime that coats the water — and dead zones is upon Lake Erie. This year, though, joining the fight is the Lake Guardian, the U.S. EPA’s 180-foot, 850-ton environmental battleship, loaded with scientists and researchers.
The Lake Guardian is on the water at a crucial time: The push is on in Washington, D.C., and Columbus to add millions of dollars to the anti-algae effort, sewage treatment plant upgrades are being put in place and there are indications that this summer’s algal bloom may be less severe than recent years.
“This is an intensive year for Lake Erie,” said Chief Paul J. Horvatin of the U.S. EPA’s Great Lakes National Program Office in Chicago. “We’ve been here to look at nutrient and phosphorus issues since mid-May and we’ll continue our research into the middle of October.”
With an 11-man crew and 13 scientists aboard, and more local researchers joining them this summer on Lake Erie, the R/V Lake Guardian is extensively sampling the Ohio waters of Lake Erie from Toledo to Conneaut. Read more…
