FREQUENTLY ASKED QUESTIONS
How do I select the correct subsea floater material?
The material is selected mainly according to operating depth, required buoyancy, cable or riser diameter, and project conditions. Syntactic foam is commonly used for deepwater applications, while PVC, EVA, and PU materials are also available for specific requirements.
What information is required for a quotation?
Please provide the operating depth, required buoyancy, cable or riser diameter, quantity, and any dimensional or installation requirements. Drawings or technical specifications are helpful if available.
What is the maximum operating depth?
Our subsea floaters are mainly designed for subsea applications from approximately 300 to 6,000 meters. Solutions for shallower water can also be provided according to project requirements.
Can the dimensions and buoyancy be customized?
Yes. Outer diameter, inner diameter, length, center bore, mounting holes, shape, and net buoyancy can be customized to suit your equipment and installation requirements.
Do you provide split floaters for existing cables or risers?
Yes. Split subsea floaters can be designed for installation around existing cables, umbilicals, risers, and other subsea lines without requiring the line to pass through a one-piece float.
Can you manufacture according to customer drawings?
Yes. We can manufacture subsea floaters according to customer drawings and technical specifications. Custom CNC-machined shapes, dimensions, mounting features, and interfaces are available.
What tests can be provided before delivery?
Depending on project requirements, dimensional inspection, density testing, buoyancy verification, water absorption testing, and pressure-related testing can be provided. Inspection and test requirements can be confirmed before production.
Do you accept prototype or small-quantity orders?
Yes. Prototype, sample, and small-quantity orders are available for project evaluation and testing before larger production orders.
Need Custom Buoyancy Solutions?
Our engineers can customize subsea floaters to meet your project requirements.
