Offshore
Flexible Wastewater Solutions Built Around Your Operation
Offshore installations operate in some of the world’s most challenging environments, and their wastewater treatment systems must be just as resilient. At G&O Bioreactors, we design and deliver biological treatment systems specifically tailored for offshore platforms, FPSOs, drillships, and support vessels.
Meeting Offshore Challenges
A leading offshore energy company needed to:
- Replace an ageing system to meet stricter effluent limits.
- Increase treatment capacity for a growing crew.
- Fit within tight existing infrastructure.
Standard solutions weren’t feasible due to physical constraints. That’s where G&O came in.
Compliance Without Complexity
Offshore wastewater discharge is tightly regulated by IMO standards, local authorities and classification societies such as DNV. G&O Bioreactors are approved to meet and exceed these requirements. Our systems support compliance with:
- IMO MEPC 227(64) including nutrient removal
- DNV type-approval
- RoHS and Green Passport environmental directives
With a design philosophy rooted in biological processes, G&O’s systems achieve compliance without the use of chemical dosing or complex automation. This simplifies onboard operation and eliminates many of the failure risks associated with traditional systems.
Sustainable and Cost-Effective Operation
Biological treatment represents the most environmentally friendly and low-maintenance method for managing grey and black water offshore. By using membrane filtration, G&O bioreactors effectively retain nutrients and microplastics, protecting the surrounding marine ecosystem. There’s no need for chlorine-based disinfection, reducing both operational hazards and logistical complexity.
Our systems also avoid the use of PLCs, enabling fast commissioning and reducing the need for specialist technicians. Crew can oversee installation and operation with minimal training – a significant advantage for offshore teams where availability of expertise is limited.
Explore Our Offshore Case Studies
At G&O Bioreactors, we have delivered customised wastewater treatment systems to a wide range of offshore operators – from energy majors to specialist support vessels. Our case studies highlight how we design, install and support biological treatment systems that perform reliably in offshore environments – whether for new builds or retrofits.
