DeepWater Buoyancy is exhibiting at the 2022 Subsea Tieback Forum in Galveston, Texas – March 1-3, 2022.
Pipeline Buckle Mitigation Buoyancy
Under certain conditions, subsea pipelines can experience lateral movement known as “buckling”. Lateral buckling causes the pipeline to be dragged across the seafloor, which can jeopardize the pipeline’s integrity. In response to this, Pipeline Buckle Mitigation Buoyancy modules are clamped onto the pipeline to control the formation of the lateral buckles and to alleviate stress. These modules decrease the lateral friction from the buckle by both reducing weight of the buckling sections and by providing a protective shell.
All modules are custom-designed to fit each application taking into consideration the designed uplift, pipeline specifications, and deployment strategy. The standard design has an integral elastomeric clamp designed to secure the modules against axial and torsional loads. All units are made using high-performance DeepTec® syntactic foam inside a thick-walled polyethylene exterior shell that provides superior resistance to impact, wear and biofouling.
Compression of the clamp is maintained by either standard hardware or by strapping systems. In either case, installation tools are provided to create the required compression for the elastomeric component.

MiniMod™ Small Modular Buoy
MiniMod™ small modular buoys are designed for lighter applications. Still rated to depths as great as 6000 meters, the standard 7-module buoy can provide up to 330 kg of buoyancy. Made from high-strength DeepTec® solid syntactic foam that is finished with an abrasion-resistant, polyurethane elastomer coating, these buoys can stand up to rough handling on-deck and in the water. The syntactic foam modules are held together and handled by use of synthetic straps, as opposed to metal hardware for corrosion resistance, ease of handling, and no loss of buoyancy.
