The Internaloo: Internal offshore portaloo
offshore welfare
Purpose-Built Sanitation for Inside Wind Turbines

Engineered for High-Performance Welfare Logistics

Why Contractors Choose Griffin

Optimised design gives unmatched Logistics and Access Engineered for Extreme Durability. - Patented structural corner extrusions allow the full size cabin to fold to a diagonal profile to pass through narrow access doorways. A full size cubicle can be passed through a narrow door. - Certified Single Point and DNV 4-Point lifting. - Dry or wet toilet solutions to suit client requirements. - 30 minute Fire-rated construction (body is self-ashing and roof is non-dripping opaque). - Hospital grade germ-free wall cladding. - Marine grade Mil'spec materials and ballasted base with tie down points allow outside usage.

Critical advantages for offshore and industrial environments.

- Seamless Four Bolt Assembly: Once inside, the cabin is quickly secured and ready for service with our four bolt assembly to keep the building aspect as simple as possible.

- Easy Dismantle Access: The unit can be craned in one piece and maneuvered through narrow turbine doors and constrained openings for easy deployment.

- Rapid Deployment: This eliminates the need to break down and rebuild the cabin at the installation site. - Durable Construction: Designed to outlast the asset's lifetime.

Patened Design

The Griffin Internal welfare solution is robust, remarkably light using Milspec honeycomb alloy panel, fire rated and certified, engineered for demanding, remote environments. Compliant for fire rated in turbine installation. Its patented construction allows for a full size toilet to fit through a narrow turbine access door.

The Griffin Internal welfare solution is robust, remarkably light, fire-rated and certified, engineered for internal and external environments. Its patented construction allows for a full-size toilet to fit through a narrow turbine access door.

The Internaloo’s Seamless Four Bolt Assembly is a huge competitive advantage, showcasing our superior, simpler, and more efficient engineering. Fewer fasteners mean dramatically faster mobilisation, quicker assembly and dismantle times, and reduced complexity. We keep the building aspect as simple as possible, reducing potential for error on site. Achieving robust, reliable security with only four bolts—where competitors require more —is proof of the Internaloo's advanced, patented construction. This level of innovation ensures rapid deployment without compromising the integrity required for industrial and offshore environments.

Engineered for true Rapid Deployment and Easy Dismantle Access, the Internaloo is designed to be craned and maneuverer into place in simplified 3 pieces (the hanger, the sides and the base), even through narrow turbine doors and constrained openings. This critical innovation completely eliminates the significant time, labour, and risk associated with breaking down and rebuilding the cabin at the installation site with a pack down system. Furthermore, its Durable Construction is designed to outlast the asset's lifetime, ensuring clients receive maximum return on a long-term investment.

It's remarkable strength of construction allowed a LOLER proof test load of 7:5:1 during certificate testing with the use of it's certified Single Point and DNV 4-Point lifting, offering both options for lifting.

Optional dry toilet with a biodegradable waste bag for zero water logistics - maximizing the Internaloo's deployment flexibility and clients requirements, ensuring technician comfort, especially in complex environments like wind turbines.

This dual capability allows the cabin to be safely installed in locations—such as near sensitive electrical or mechanical equipment—where water must be avoided to prevent a safety risk. By choosing the dry system option when necessary, maintaining compliance and operational safety.

Ultimately, this flexibility ensures that, regardless of the site restrictions, the cabin can still be installed to bring the highest level of comfort and dignity possible to the situation.
