A solution for every challenge
At G&O Bioreactors, we don’t just respond to complexity – we thrive on it. From navy vessels to offshore platforms, passenger ferries to retrofit projects, each marine or offshore installation presents its own set of technical, regulatory and operational challenges. And each one is an opportunity to grow and deliver a smarter, certified solution.
Whether operating under strict IMO standards or working with NATO-aligned navies, regulatory compliance is at the core of every system we deliver. Our Bioreactors hold MED and IMO MEPC 227(64) certificates, and our systems are designed to meet the highest global standards for onboard wastewater treatment regardless of vessel type or operating environment.
“Navigating the tides of technical challenges where most see the complex engineering in ship and offshore installations as an adversity, for G&O, it presents an opportunity. As the maritime business landscape evolves, so do our solutions – ensuring that every technical installation and challenge is smoothly crafted in innovative solutions that turn these challenges into effective success stories for our customers,” says Thomas Højbo Hansen, Head of Sales, G&O Bioreactors.

Navies: reliability and compact design
Naval ships demand compact, rugged systems that can operate under extreme conditions and within tight space constraints. Our installations are tailored to meet these needs, ensuring long-term reliability and ease of integration – with documentation and support fully aligned with military procurement requirements.


Offshore installations: safety and adaptability
Wastewater treatment on offshore rigs and platforms requires robust systems with long maintenance intervals and high redundancy. G&O Bioreactors provide modular, plug-and-play solutions that can be adapted to new and existing platforms alike – always in compliance with international offshore regulations.
Passenger vessels: discretion meets performance
Cruise ships and ferries must combine high-capacity treatment with minimal disruption. We design systems that deliver top performance while staying quiet, compact, and easy to operate – allowing operators to maintain environmental standards and passenger comfort simultaneously.


Retrofit projects: smarter reuse, lower footprint
When retrofitting older vessels, we help customers upgrade their wastewater systems without overhauling the entire infrastructure. Our team provides tailored solutions that fit the space, piping and power already onboard – saving time, reducing cost, and cutting environmental impact.
At G&O Bioreactors, we deliver tailored, certified, and proven solutions that enable shipowners and operators to meet today’s demands and prepare for tomorrow. No matter how challenging the installation, there is always a solution
