BARDOT Ballast Modules provide additional weight on Flexible Pipes / Umbilicals / Cables to ensure the bottom stability (Static) or create the lazy wave shape (Dynamic).

BARDOT Ballast Modules can be made of steel or lead and are composed of 2 or 3 elements fastened together on the line requiring additional weight.

To protect them from corrosion, the steel modules are equipped with sacrificial anodes, the lead modules are inert and do not require protection.

Anti-sliding pads made of qualified polychloroprene ensure immobilization and prevent from slippage of the modules on the lines.

BARDOT Static Ballast Modules are used to provide the additional weight required for the bottom stability of Flexible Pipes / Umbilicals / Cables. Modules are designed to withstand the whole service life of the lines, up to 30 years. Extra weight in water can range from 5kg up to 100kg, with material density from 7 to 11.

Our engineering performs bottom stability analysis to optimize the design and provides fit for purpose solutions.

BARDOT Static Ballast Modules compete directly with concrete mattresses for bottom stability solutions. In-line installation during laying operation allows extreme offshore time reductions.

BARDOT Dynamic Ballast Modules are often used with buoyancy modules to create lazy wave or other shapes for Flexibles Pipes/Umbilicals/Cables.

Our qualified solutions of modules can either be directly clamped on the line or assembled through an internal clamp. Our internal clamps for Ballast Modules have been jointly developed with our buoyancy modules solutions. It is fully qualified for dynamic applications. Modules are designed to withstand the whole service life of the lines, up to 30 years. Extra weight in water can range from 5kg up to 100kg, with material density from 7 to 11.

Specific polymer materials allow our clamp to withstand high temperature of pipes, in case of HP/HT fields.
