Seafloor Lander Buoyancy Project

Seafloor Lander Buoyancy Modules for Subsea Research & Observation Applications

Project Overview
FLOAT X supplied syntactic foam buoyancy modules for a seafloor lander system used by a European university for subsea research and observation operations.

The buoyancy blocks are designed for an operating water depth of 500 meters and are integrated into the client’s lander platform.

Thanks to the stable performance and consistent quality, the client has reordered this product multiple times, making this a long-term and repeat cooperation project.

The Challenge

• Operating depth up to 500 m

• Requirement for stable buoyancy and compact design

• Lander used for long-term observation and repeated deployment missions

• Need for reliable, durable, and cost-effective buoyancy solution

• Product must maintain consistent performance over repeated deployments

The FLOAT X Solution

FLOAT X provided custom-shaped seafloor lander buoyancy modules manufactured from high-quality syntactic foam.

The buoyancy blocks are:

• Precisely machined to match the lander frame structure

• Optimized for 500m water depth rating

• Designed for long-term repeated use in harsh subsea conditions

• Protected with surface coating for seawater resistance

This solution has been validated through multiple deployments and repeat orders from the same customer.

Key Specifications

• Material: Syntactic foam

• Density: 0.36 g/cm³ (360 kg/m³)

• Rated Depth: 500 m

• Application: Seafloor lander buoyancy

• Design: Custom-shaped blocks for lander integration

Project Result

The buoyancy modules have been successfully deployed in real subsea operations and have shown stable and reliable performance.

Due to the good performance and consistent quality, the customer has placed several repeat orders for the same buoyancy product.

Why It Matters

This project demonstrates FLOAT X’s capability to deliver:

• Reliable and cost-effective seafloor lander buoyancy solutions

• Stable quality for long-term and repeat customers

• Engineered syntactic foam products suitable for academic and commercial subsea applications
