Subsea Buoyancy Modules for Offshore Applications in Brazil

Project Overview

FLOAT X supplied a modular buoyancy kit system for a major offshore survey contractor in Brazil, designed for flexible subsea operations at water depths of up to 3000 meters.

The client required a buoyancy solution that could be quickly configured and adjusted for different subsea tools and mission profiles, instead of using fixed, single-purpose buoyancy blocks.

The Challenge

• Operating depth up to 3000m

• Need for flexible and modular buoyancy configuration

• High requirements for strength, durability and reliability in offshore environments

The FLOAT X Solution

FLOAT X delivered a Modular Buoyancy Kit made from deepwater-grade syntactic foam with a protective PU coating.

The system consists of stackable cylindrical modules with different buoyancy ratings:

20 / 50 / 100 / 300 / 500 kg

These modules can be freely combined to build the required buoyancy for different subsea equipment quickly and efficiently.

Key Specifications

• Material: Syntactic foam with PU coating

• Density: approx. 0.5 g/cm³ (500 kg/m³)

• Rated Depth: 3000 m

• Design: Cylindrical, modular, stackable

• Applications: ROVs, subsea tools, seabed equipment

Project Result

The buoyancy system was successfully deployed in subsea operations and, according to the client, “performed very well in operation.”

This modular system significantly improved the flexibility and efficiency of offshore equipment configuration.

Why It Matters

This project demonstrates FLOAT X’s capability to deliver deepwater-rated, engineered and modular buoyancy solutions for demanding subsea applications worldwide.
