impact or collision protection, machines and plants
Noble yachts brilliantly protected by ACE
Fenders protect ships from collision damage during berthing manoeuvres. So that yachts can also survive soft and ungentle touches with other boats or jetties, ACE has worked with a customer to design ideally suited, adjustable stainless steel versions of MAGNUM industrial shock absorbers MA/ML and bring them to series production readiness. The previous solution was discoloured by penetrating salt water, which had no effect on the functionality of the fenders, but looked unsightly. The new complete package works both technically and visually to the complete satisfaction of even the most demanding yacht owners.
Profile Dampers - TUBUS TS
Damping for offshore landing structures
The maintenance of wind turbines in open seas has long resulted in damage to maintenance boats. Because of impact velocity and swell, an increase in the boat's mass of up to 20 % must be taken into account when landing on a rigid mooring structure. It is only since the landing operation has been carried out with the aid of the ACE company's TUBUS structural dampers that cable repair and maintenance work on wind turbines has been made safe for both personnel and equipment. The TUBUS TS84-43 used here are seawater resistant and withstand ambient temperatures from -40 °C to +90 °C.
Profile Dampers - TUBUS TR-L
Saltwater-resistant impact protection for lifeboats
When launching lifeboats, it is theoretically conceivable that there will be contact between the ship and lifeboat. Launching appliances with protective bodies are fitted in order that the lifeboat is not damaged. Since TUBUS TR-L profile dampers have been doing this job on one of the largest passenger ships in the world, the regular replacement of the damping elements has become a thing of the past. This is because in contrast to earlier solutions made of rubber, the material of the ACE profile dampers does not become brittled or cracked, even in contact with salt water and UV irradiation.
Safety Shock Absorbers - SDP63 to SDP160
Impact absorption for lock gates
Driving into lock gates should be specifically facilitated when navigating through Dutch river locks. That is why ACE developed special dampers, based on existing SDP safety shock absorbers but with optimized characteristics, a fixed stop and a stroke of 800 mm. These are able to absorb 500,000 Nm, which means they can cope with fully loaded ships and also the mechanical impacts resulting from water movement. To return to the initial position, the safety shock absorbers operate on the same nitrogen-based principle as the gas springs produced by the damping specialists in Langenfeld.
Rubber-Metal Isolators - Flex Locs
Shock relief for lifeboat housings
In the present case, when compared to screw connections, the modern quick connection elements produced by ACE have a distinct advantage: their material makes them resistant to the most diverse range of aggressive media, including salt water. Because of this, they provide protection to the housings which encase emergency pressure canisters that are used for the launch of lifeboats. In the most innocuous scenario, the housings would lose their stability through the effects of rust. In the worst case, damage to the pressure canisters could occur or to the entire davit construction.
