Trelleborg Introduces New Buoyancy Module System
Trelleborg’s offshore operation recently developed a new standardized buoyancy module system.
The Sstandardized buoyancy module is made up of small elements that stack together to increase the overall uplift of the complete distributed buoyancy module. The buoyancy segments are designed to mechanically lock around the clamp to securely attach the assembly to the desired location on the riser, the company explains.
Jonathan Fox, senior product development engineer with Trelleborg’s offshore operation, states: “We recognized a requirement to deliver buoyancy products in less time for projects with short lead times. Through our customized innovation process, we were able to qualify and standardize a buoyancy module for subsea or surface applications that can be delivered in around half the time of a typical buoyancy module. In addition, we were able to ease handling of the buoyancy modules by incorporating synthetic rubber feet to the bottom of the finished assembly to prevent handling damage and reduce assembly time.
“Because the product consists of known volumes and up thrusts, we are putting the upfront engineering into the hands of our customers, reducing the time needed to achieve an approved product design.”
The Standardized Buoyancy Module system can be adjusted to operate in seawater depths from surface to 2,500 meters by adding or removing elements.
