C-TECH Precision Strength

Q: My lab is planning a large instrumented array for deployment in the deep ocean. The electronics will be housed in sealed glass spheres, and I'm worried about possible implosion. If one sphere collapses, the shock wave might break all the others. How can I protect the array against sympathetic implosion? - R.A., Hawaii

A: It sounds like C-TECH "Precision Strength" syntactic foam might be the answer. This material can be custom-formulated to have a precisely defined crush strength. If blocks of C-TECH foam were placed inside the hollow glass spheres, they would control collapse rate in the event of breakage and prevent catastrophic failure. L.K., Cuming
     
      Q: I keep sending inquiries to your web site, but you never answer! What's the matter? Don't you guys want my business? - P.D., USN

A: Sorry, but you're addressing your questions to the wrong website, namely, our competitor's! The confusion comes from one of their sub-units with a name similar to ours. They may be unable to respond to you quickly. I've forwarded your inquiry to our sales engineering department for prompt action. - L.W., Cuming
     
     


C-THERM Insulation

Q: I've got to write the specification for thermal insulation on the vertical risers on our latest floating production rig. The problem is, we also need a lot of buoyant lift to support the risers. How can I integrate the insulation and flotation functions? I'm looking for the simplest possible solution that also saves us some money. - S.B., Texas

A: There are a couple of approaches. One uses special lightweight and naturally buoyant cast-on-pipe C-THERM insulation. Our Louisiana factory specializes in this technology, and it's been used successfully many times. Another is to place the insulated pipe inside separately cast C-FLOAT buoyancy modules. We can recommend the optimum solution for you, depending on depth, temperature, and total lift required. - L.W., Cuming
     
      Q: I'm struggling to make sense of the various terms and measurements used in designing thermal insulation systems. Every supplier seems to have his own approach. What generally accepted industry standards are being used? - S.W., Texas

A: This can be a pretty complicated subject. A good starting point is the Joint Industry Report "Recommended Practice for Insulation and Buoyancy Systems" prepared by MCS International in July 2002. For a detailed explanation of how Cuming Corporation calculates performance of C-THERM insulation products, download Technical Note 600-4 from our website. L.W., Cuming
     
     


C-FLOAT Flotation

Q: Help! Our drill rig was damaged in a hurricane, and it's docked and awaiting repairs. Meanwhile, hundreds of syntactic foam riser buoyancy modules have been taken off and laid out in an open field for storage. The sun down here is bright and hot! My boss wants to know if we need to protect the modules from "UV damage." What's he talking about? - E.D., Louisiana

A: Not to worry. "UV," or ultraviolet radiation from sunlight, can be damaging to ordinary plastics. However, C-FLOAT syntactic foam is filled with tiny hollow glass microspheres. The glass microspheres are efficient scatterers of light - in other words, they strongly reflect or deflect UV, and prevent its penetration. Therefore, no damage will occur, and no special protection is required. - V.W., Cuming

     
      Q: Our riser system is in danger of damage from high currents. The string is already equipped with your C-FLOAT buoyancy modules. What can I do to mitigate the effects of VIV (Vortex-Induced Vibration)? - D.S., Texas

A: Cuming Corporation makes fairings to provide excellent VIV protection. The fairings are molded of fiberglass, weathervane into the current, and are neutrally buoyant. We have a number of existing designs, and one may work for you. I suggest you take a look at Technical Note 100-8 on our website to learn more. - R.W., Cuming
