BUOYANCY - MODULAR BUOYANCY

modular buoyancy

GENERAL

Bardot Modular Buoys are mainly used as mooring, for structures laying or subsea markers.
BARDOT Group proposes a wide range of material and configuration to reach your needs.

DESIGN

A modular Buoyancy Module is composed of buoyancy elements, which provide the uplift force, which are assembled on a steel support, designed to withstand specifications' load cases.

BUOYANCY ELEMENT

A Buoyancy Element is made of syntactic foam encapsulated in a polyethylene external skin.
Syntactic foam properties are optimized to reach the required buoyancy at operating water depth.
The external skin provides external impact and marine growth protection.
The skin is made from high performance polymer and designed for permanent applications in seawater.
The shells are designed with grooves to be centralized relative to each other.

STEELWORK

Bardot Buoys are assembled with a central steel support. Bardot can propose various types of end fittings.
A cathodic protection can be supply if needed.

MANUFACTURING

BARDOT Group manufacturing site works with an advanced in line process to guarantee the constant best quality. Ratio are monitored by sensor during all the casting operation with an auto regulation of the flow.

TESTS

HYDROSTATIC TESTING

All Bardot syntactic foams are tested in our hyperbaric chambers capable of simulating 6000m water depth.
Crush test and Instrumented Buoyancy Loss test are performed as per most critical standards.

PAD EYE TESTING

Lifting pad eyes are proof load tested in accordance with DNV Rules 2.7-3 (Standard for certification, Portable Offshore Units). The load test will be witnessed by a recognized third party.

MATERIAL TESTING

All used materials are tested in our laboratory to define their thermal and mechanical properties.
