The 20ft Containerized Dive Support Machinery Control Unit is a fully engineered breathing-air machinery module designed to support large and complex commercial diving spreads. Built within a certified 20ft DNV Offshore or ISO container, this system offers extensive HP/LP breathing-air capability, expanded air storage, and a fully integrated air management package suitable for chamber operations and multi-diver dive panels.
A typical configuration includes two Bauer high-pressure compressors, one Quincy low-pressure compressor, and two independent 12 × 50 L 200 bar air racks—one dedicated to chamber supply and the other to the dive panel. All breathing air lines are stainless-steel plumbed to a penetration plate, enabling safe and clean external connection.
To ensure safe and efficient operation, each compressor is fitted with forced exhaust fans, removable louvers, and intake filtration. The internal machinery layout provides optimal access while maintaining operational airflow and equipment longevity.
Fully compliant with IMCA D023 and D018, the entire system is delivered with a complete FMEA and Bureau Veritas class-witnessed test certification, guaranteeing full traceability, reliability, and operational readiness.
Ideal for offshore saturation systems, multi-diver air spreads, or long-duration surface-supplied diving operations, this 20ft system provides a high-capacity, centralised solution for professional diving contractors.
