^News item September 2018: Reliance Hexham Pty Ltd of NSW Australia who specialize in the design and manufacture of lifting solutions for the mining industry, has provided this YouTube video showing the release (by a Sea Catch Model TR8 at the beginning) of a test conveyance fitted with sand bags to simulate passenger weight. The total mass of the conveyance in this test is 12,000 kg, equivalent to about 10 small cars. The specially built inclined railway test track is constructed at a slope found in a mine drift, a steep underground railway, often many kilometers long connecting the surface to underground operations. The conveyance typically runs up and down the drift using a winder and wire rope. If, for any reason, the rope breaks, the “Reliance Franlane” ™ emergency braking system is activated and brings the conveyance and passengers to a stop on the inclined railway.

ReleaseLeverGuard
^News item September 2016: "On some of our jobs, we have been concerned of accidental mechanical tripping of the Sea Catch from the numerous cables and lines we have when lowering items to the seafloor. Attached is a photo of a modification we made aboard the ship to prevent this from happening. The ¼” plates (shown in black) are removable and still allow a small prybar to open the lever when rigging on deck. It worked well, and our worries are over. The plates have enough clearance so that the Sea Catch can be fully closed, but lines or cables cannot lift up on the lever." Shared by Kirk Connally and his team at L3 MariPro.

^News item September 2016: "Here is an image of a Sea Catch TR3 in action releasing our giant swing. The device has proven itself to be ideal for our intended use. The speed and smoothness of load release is definitely a highlight for our guests and adds to the thrill factor on our swing. Also, the amount of force required to release the load is ideal for some of our younger guests, meaning they get to experience the drop firsthand. We are more than satisfied with how well the Sea Catch works and will continue to use it at our operations. Thanks for making a great product", Ron Betts - owner/operator, Treetop Flyers.

Sea Catch TR5 before refurbishment Sea Catch TR5 after refurbishment
^News item September 2014: The Sea Catch TR5 shown above at left has undergone at least 10,000 cycles in the last 2 years without any maintenance and was returned to us for refurbishment. The shackle connection openings (jaw and rear hole) show the most wear and the overcenter snap had completely gone. Due to poor maintenance, all four pivot pins as well as both toggle plates needed replacement. While operating a Sea Catch in this condition is not safe, it is a testament to the durability of the device for it to function so long with so little care. The photo at right shows the same unit refurbished. It was put right back into operation again.
Sea Catch TR18RAM emergency disconnect
^News item April 2013: Chevron USA recently used a Sea Catch TR18RAM as an emergency disconnect on the mooring line that secured an ocean going barge to the stern of a drill ship for well test flowback.

The unit was delivered to Chevron by Sea Catch dealer Blue Ocean Tackle, Inc. (Photo courtesy Chevron USA)
Sea Catch TR10 fitted with Hitch Pin Spring (HPS) modification Sea Catch TR10 fitted with Hitch Pin Spring (HPS) modification
^News item December 2012: Nuytco Research Ltd. of North Vancouver, Canada has devised an innovative way to remotely "pull" the safety pin on their Sea Catch TR10 as shown above. The pin is fitted with a compression spring on one end that ejects the pin as soon as the pin's R-clip is pulled away from the other end. In this way the safety pin can be pulled from the same direction as the release lever to facilitate the use of the hitch pin in semi-remote applications. The pin is tethered to the unit body to prevent its being lost upon release. McMillan Design is offering a similar Spring Safety Pin (659KB PDF) as an option.

Bay College Team with Yo-Yo Yo-Yo being prepared for Guiness World Record attempt
^News item July 2010: Congratulations! Bay College's Yo-Yo Team achieved success with their attempt at breaking the Guiness World Record for the world's largest functioning yo-yo. A Sea Catch TR5 was used to release the 1,700-lb yo-yo. Team member Mark Cocco states, "Your quick release worked perfect for us. We had one rope on the safety pin, which pulled out easily, and then another rope on the release lever. Even with the release at 100 feet up, there were no problems during any of our 5 drops!" Check out the YouTube video. Photos and video by Mark Cocco/Bay College.
Seaflex 5-ton MBUs on 3-pipe bundle Seaflex 5-ton BMU with Sea Catch TR7 Crocodile
^News item August 2010: Seaflex was asked to propose a buoyancy system to float three 2.5km strings of concrete-coated LNG pipelines in a bundle through a tributary in Soyo, Angola. The company was also asked to provide a quick release system which would allow for the buoyancy units to be removed from the pipeline in a safe manner, without the use of divers. The answer was a combination of 660 Seaflex 5-ton Mono Buoyancy Units (MBUs) with a Sea Catch TR7 for each MBU. Once the pipelines were in position, the air was release from the bags allowing the pipelines to settle on the river bottom before the deflated bags were disconnected from the pipeline by pulling the Sea Catch release lanyard at the surface. It later was found out that the main reason for requesting a diver-less buoyancy release system was the risk from local inhabitants..... pythons and crocodiles (like this one recently caught nearby)!
