New Innovations at Quantum REDEFINING the Future

NEW 5000S CONTROL SYSTEM

All Quantum Systems are operated via a control unit that uses customized algorithms to direct the stabilizing movements to the fins or rotors. In early 2022, Quantum launched the new 5000S control system, representing a major advancement in control technology.

The 5000S uses a plug-in/add-on modular platform that effectively supports old, current and future control systems and their corresponding algorithms. It has the ability to execute a multitude of requirements, such as underway only, retractable and zero speed functions. The system features remote access capabilities for prompt troubleshooting, recording options that can be stored and downloaded later and a customizable glass bridge interface. As an added convenience, the new control can store drawings, technical data and fluid recommendations. The functionality, flexibility and expandability of the 5000S will carry the advanced control technology well into the future.

F45 HYBRID - HYDRAULIC/ELECTRIC - INTEGRATED HYBRID POWER SYSTEM

With a prototype under development and a patent pending, Quantum is introducing a new state-of-the-art, integrated hybrid hydraulic/electric power unit. The F45 Hybrid uses the best attributes of both power sources. It offers smooth power that does not fl uctuate and requires 60% less power than a standard hydraulic system, only consuming energy as required, when required. There is a lot of wasted energy with a traditional hydraulic system (approximately 40%), but the F45 Hybrid drops to less than 1kW when in standby mode.

Electric fin stabilizers on larger vessels (60m+), become cost prohibitive due to the prices associated with gear boxes and servo motors. Electric fi ns with gear boxes must be designed to withstand slamming loads which is easier for hydraulic systems to handle with relief valves. The new Hybrid uses a dynamic servo motor, coupled to a low inertia hydraulic pump, that greatly simplifies the overall system and removes all the components that make the hydraulics inefficient. The F45, is effi cient, quiet and does not generate heat. This innovative power pack will be available in June 2023.

DYNAMIC LOAD CONTROL

With a patent pending, the new Dynamic Load Control (DLC) helps reduce the heavy electrical cyclic loading and the amount of accumulator storage required in operating a stabilizer system. Typical stabilizer systems require large amounts of accumulation to maintain constant system pressure. The heavy demand for power, can cause the hydraulic pump(s) to go from low to high loads in a short period of time, pulling down the voltage causing “brown outs.” This new technology eliminates these fluctuations and reduces the accumulator volume by 50%-90%. The DLC unit can be added or retrofi tted to an existing system, with minimal system modifi cations.

MARINE TECHNOLOGIES L.L.C

One captain’s mission to ‘bullet proof’ his A/C system

By Lucy Chabot Reed

After more than 40 years playing with, working on and running boats in several sectors of the maritime industry, one thing about yachting made Capt. Herb Magney mad: “Why does the air conditioning only break down when guests are aboard?” The last time it happened to him was in Sicily, thankfully his crew were dynamic — stews distracted the guests with shore-side activities, engineers applied band-aids and deck officers created diversions so that the guests didn't really know what was happening. But he did know, and he was determined that this time would be the last time. "The last copper condenser I had didn't last six months; it was supposed to last a couple years," Capt. Magney said. "I want it bullet proof, I want titanium! I know it’s out there because I've seen it used in commercial marine applications. So, I was calling around for a replacement and I notice that everyone was calling the same guy in San Diego. So I called him." Tim Mournian, owner of now Texas-based Titanium Marine Technologies, has spent Copper

decades working in the commercial fishing industry. Those boats depend on their refrigeration systems to hold the catch until they get ashore. When a condenser breaks out there, weeks of work and hundreds of thousands of dollars are lost. So these professionals were keen to consider a fail-safe method, even at a premium over copper. "I can safely say we changed the way the international fishing industry freezes their catch," Mournian said. "But once it [a titanium condenser] goes in, it never goes away, we do not get repeats. So we’re always in search of new markets." He has expanded to working with all types of vessels in North and South America, Mexico and Asia Pacific. In July of 2019, Capt. Magney found his website and Magney’s problems were solved.

Titanium

"The yachting market is exciting to us

because they respect quality," Mournian said. He offers a warranty of 10 years on his heat exchangers. The failure in these traditional systems is a simple matter of chemistry. The standard condensers are made of copper and nickel, and these metals tend to corrode when in contact with seawater. Zincs can keep that at bay, and will work when preventative maintenance is followed rigorously. Let it lapse, even a little, and the results can be unforgiving. Over time, failure is inevitable. "Any boat that we have a failure on, we're now pushing titanium," said Jeff Wells, Service Manager with Elite Marine Air Conditioning in Fort Lauderdale; which is working on its ninth vessel installing heat exchangers from Titanium Marine. "From our standpoint, copper is a liability. When the metal fails and fills the circuit with seawater, it's worthless. It can cost tens of thousands to repair. We're pushing titanium for anyone who wants to change." He noted the delivery time for custom titanium units has been faster than traditional cupro-nickel units. Normal delivery times are eight weeks versus eighteen to twenty four weeks for copper units. The big bonus is that Titanium Marine condensers are made in the USA, not China.

On M/Y Ocean Club, the 161-foot (50m) Trinity Capt. Magney ran for years through dual charter seasons in the Med and Caribbean, the standard set of condensing equipment historically lasted only two years. "Four years ago, when I got on, they were replacing condensers and they were already going bad a year later when the new boss had a survey done," he said. "We replaced them all two years ago in July, in the middle of the Med season with lots of stress and a huge amount of extra cost." After about six months, one of the condensers began to fail again, so Magney sent it to the builder for analysis. It was determined there was a factory defect. When he asked the factory about it, "they said, no, you must have done something wrong. But the other one was running just fine. This was in less than a year!" There was no supportive science, just poor materials and workmanship. That's when Herb started looking around for a better solution. "This is ridiculous, let's take it up a notch," Capt. Magney said. "We can find another manufacturer, coat it, or something. I found titanium when I researched industrial and other commercial shipboard applications. Fishing boats will lose everything without refrigeration, so I’m looking to them, and they’ve all gone with Titanium.”

At first, he thought Titanium was out of reach. The first couple of estimates came back at $25,000-$30,000, even $40,000, with six-month deliveries. Then he found Mournian and Titanium Marine Technologies. The dream became a reality.

So why hasn’t the industry embraced this panacea before now? Primarily, the cost. Titanium parts can be up to two to three times the price of their copper-nickel cousins.

Mostly that’s because the metal is expensive and hard to work with. Welding titanium takes an argon gas environment and usually cannot be done at sea. The process is very labor intensive and the materials are challenging to work with. They require a different set of skills. “Yachting is an interesting market because they demand quality and reliability. Long-term yacht owners also consider the total cost of ownership”. However, it is not common place to calculate the real return on investment. Most decision makers only go for low price. “If you are replacing these things every two to five years, how much is that over the life of the boat. Repairs, time off charter, replacement gear; it all adds up fast.” Magney said. Still, it’s a big nut up front, one perhaps more easily digested after a mid-charter crisis. Here’s the actual story that “broke” Capt. Magney’s A/C condenser back. “Two years ago, I had a Colorado family onboard. He was the owner of a 50m Christensen charter boat for three years. He knew the business.”

This was when the A/C was about to fail. “We’re hustling all over, collecting bits and pieces. We had the condenser shipped to Naples. Other parts to other places. It was like herding cats, in Europe, in the middle of Med season, at the end of the June/beginning of July. I’m just praying to God, please, make this A/C system last one more week.”

“We get down to Sicily and we’re all good. We’re moving to Syracuse on Friday night. Three-quarters of the way down the coast, the engineer calls up, the whole engine room is in a fog, there’s sprayed oil mist everywhere. The A/C has sprung a hole” “Great. Can we bandage it? I tell the girls to control the heat, don’t open doors, yada, yada. I do what charter captains do. We get to Syracuse and I tell the guests, here’s what’s going on. We send them ashore and many hours later, the repair is made. By 2:30 am, we’re starting to cool down.” “We had a great time in Syracuse, then a couple of hours out of Capri we got another leak. We divert to Ischia. We get tours set up

and send the guests ashore. We got an A/C repair man. The agent had gear and a guy there fast and had the repair made.” “Then we head to Sardinia to have the whole thing replaced. It took a lot of technical welding in a cramped space. That part of the job alone, just the technician, was 3,200 Euros. I had to put all the crew in houses ashore. It was a 21,000 Euro job.” Mournian said he is excited to be working in the yachting industry. He’s delivered about 40 units to large yachts thus far, and he’s begun calling on builders and A/C skid packagers to offer titanium condensers as an option. “The value is in the fact that it won’t wear out, corrode or erode.” Magney said. “Titanium doesn’t care how fast you put the water through. And you don’t have to change out the zincs every two weeks. You will never have to replace it. It’ll last longer than the boat.” Plus titanium is a better metal for bio-fouling and corrosion resistance.

His second condenser was installed and Magney is now working with Mournian to manufacture other parts that tend to corrode and fail such as the engine cooler on electrical generators. Pretty soon, the only key worry all charter captains and crew will have – how to keep the clients engaged when the weather turns!

Titanium, when it has to LAST!
