Your Seacocks Specialists Discuss How to Use Marine Thermal Cameras to Your Advantage

Raritan Engineering your seacocks distributors would like to share with you these topics we thought would be of interest to you this month regarding the benefits of marine thermal cameras.

Your seacocks manufacturers talk about marine thermal-imaging systems such as those from FLIR and Iris enhance navigational safety at night by enabling boaters to see obstructions such as lobster-pot buoys, floating debris and other unlit, low-lying objects that might not show on radar.

This technology can also help you find fish. With thermal imaging, for example, you can see weed lines and kelp paddies on the ocean at night, says Lou Rota, vice president of worldwide sales for FLIR Maritime. Such floating vegetation, which attracts offshore fish, possesses minute heat differences that thermal imaging can detect.

Thermal cameras can also see fish at night. “We’ve had a lot of people saying that they’ve hooked tuna after finding breaking fish before daylight by using a thermal-imaging camera,” says Rota. “Many anglers also tell us that they can spot schools of bait fish dimpling the surface in the dark.

Black Hot shows warmer objects in darker shades versus the traditional White Hot thermal image, which turns warmer objects a lighter shade.

Ever notice how things often change temperature before they fail? Cold things get hot, hot things get cold? So it figures that an infrared, or thermal, camera would be a great tool for preventive maintenance. 

Finding a Thermal Detective

Many surveyors have added thermal detecting to their services, but do your due diligence before hiring one. Not all are qualified—some have the camera, but not the experience and expertise to interpret the images accurately.

Finally, a professional thermographer will have better equipment than you or I will buy, unless we want to get silly with money. It can record 20 minutes of radiometric data at 30 frames per second (essentially thermal videos) that Allinson can then analyze frame-by-frame; many thermal cameras record, but don’t allow analysis later. It’s a lot more camera than most of us need.

Be Your Own Thermal Detective

Hiring a thermal detective for a one-time scan only tells you what’s what at the time, but problems can appear unexpectedly on a boat. So the best way, I think, to use thermography in a scheduled maintenance program is to invest in a thermal camera (you don’t have to spend 40 grand), acquire the know-how to use it skillfully, and make it a step in your maintenance program.

Thermography Training

You’ve bought a thermal camera, and now you have to figure out how to use it. There are many paths to enlightenment, and they all start with Googling “thermography training.” 

Certification training, however, isn’t free: A four-day Level I Certification course, taught in a classroom, costs $1,995. (Level II and III courses all cost the same; each builds on the previous level.) I think certification is a necessity if you’re planning on making money with your thermal camera. 

 But if you just want to maintain your own boat, maybe you should save your money. Amazon.com has a raft of thermography books, from expensive textbooks to nearly free e-books. Before dropping two grand, plus travel expenses, for classroom training, maybe just try a little reading.

Go Thermal Full-Time

Based on the Lepton micro-thermal camera, the AX8 system connects one or more cameras with a laptop or  multifunction display running the operating system and offers full-time thermal monitoring. 

It uses MSX technology to create detailed images. The boat owner can draw regions of interest on an image, add spot meters to watch them closely, and set too-hot and too-cold alarms. 

Cox says the AX8 system is easy to connect. “If you can plug in a cable, you can do it,” he maintains. The system is wired with Ethernet cables; each camera has an I.P. address, so you connect to it like you do any other network device over an Ethernet. It works very much like a video surveillance system.

Playful Orcas Caught Chasing A Boat From Underwater Camera

Have you ever thought about what it would be like to be chased by a pod of orcas? Well, wonder no more.  A man was boating off the coast of Norway and ran into a pod of orcas, something I am sure that most of us would love to see.  I would be happy to see these amazing creatures from the water’s surface.

The orcas seem to be curious about the boat that is motoring away on the surface and continue to follow it for long enough for us to enjoy their beauty.  The members of the pod swim in a slightly different ways, but they all head in the same general direction.

And it looks like they are enjoying chasing the boat; almost as much as we enjoy this unique video.
