3F360-GCS™ Floating Oil Skimmer
Guided Control System for Enclosed & Aboveground Storage Tanks
The 3F360-GCS™ Floating Oil Skimmer System is engineered for continuous oil removal in enclosed and aboveground storage tanks where liquid levels fluctuate. Built on the proven 3F360 360-degree floating weir platform, the GCS configuration allows controlled vertical travel inside large industrial tanks—eliminating the need for complex rigid riser piping assemblies.
The Storage Tank Oil Removal Challenge
- Changing liquid levels
- Limited internal access
- Need for continuous surface oil removal
- Structural constraints at tank penetrations
- Mechanical stress caused by rigid piping systems
Traditional tank skimmer systems often rely on fixed vertical riser pipes with multiple elbows and knuckle joints. These assemblies increase installation cost, structural load, and maintenance exposure. The 3F360-GCS™ eliminates that rigidity.
How the 3F360-GCS™ Works
- Model 3F360 floating weir skimmer rests on the liquid surface
- Skimmer travels vertically as tank levels
- Heavy-duty braided stainless-steel guide cables maintain controlled alignment
- Adjustable patented Spin Down Weir® accepts oily water from all directions (360 degrees)
- Recovered oil exits through a flexible discharge hose that follows level changes
The result is continuous oil skimming inside enclosed storage tanks without rigid vertical riser assemblies.
Guided Control System (GCS)
The system operates using a simple, mechanically reliable belt-skimming process:
- Two heavy-duty braided stainless-steel guide cables
- Roof-mounted fastening hardware
- Floor-mounted fastening hardware
- Flexible discharge hose connection
This configuration:
- Maintains controlled geography within the tank
- Keeps the skimmer aligned on a defined vertical path
- Reduces stress on tank penetrations
- Simplifies installation compared to fixed pipe systems
- Allows reliable operation during fluctuating tank levels
Key Benefits for Industrial Tank Operators
- Continuous oil removal during normal tank operation
- 360° oil intake — no directional limitation
- Eliminates rigid riser pipe assemblies
- Fewer mechanical joints and stress points
- Reduced structural loading
- Lower installation complexity
- Durable 304 or 316 stainless steel construction
- Proven 3F360 floating weir performance
Based on the Proven 3F360 Floating Weir Platform
The 3F360-GCS™ utilizes the same 360-degree floating weir technology used in applications such as:
- Sumps
- Equalization tanks
- Oil-water separators
- Settling and leachate ponds
- Municipal and industrial wastewater systems
- Duckweed removal where adhesion-based skimmers are not applicable
The patented Spin Down Weir® allows adjustable oil recovery while a protective screen helps prevent debris intake. The GCS configuration adapts this proven floating oil skimmer technology specifically for enclosed storage tank environments.
Typical Applications
- Aboveground storage tanks
- Enclosed industrial tanks
- Waste oil holding tanks
- Refinery and petrochemical storage
- Power generation facilities
- Industrial bulk fluid storage systems
Why Use a Floating Oil Skimmer in a Storage Tank?
In storage tank environments, early removal of floating oil:
- Reduces contamination
- Protects downstream treatment systems
- Improves oil-water separation efficiency
- Minimizes manual oil removal
- Supports environmental compliance
A properly designed floating oil skimmer system allows surface oil to be removed continuously without draining or interrupting tank operations.

Frequently Asked Questions
How does a floating oil skimmer work in a storage tank?
A floating oil skimmer rests on the liquid surface and removes accumulated oil as tank levels rise and fall. The 3F360-GCS™ uses guide cables to maintain controlled vertical alignment during operation, allowing continuous surface oil removal without rigid piping structures.
Can the 3F360-GCS™ be used in enclosed tanks?
Yes. The system is specifically designed for enclosed and aboveground storage tanks where internal access is limited and liquid levels fluctuate. The Guided Control System keeps the skimmer aligned along a defined vertical path.
What is the advantage over fixed pipe skimmer systems?
Traditional tank skimmers rely on rigid vertical riser assemblies with multiple joints. The 3F360-GCS™ eliminates that rigidity, reducing structural load, simplifying installation, and minimizing mechanical stress points inside the tank.
What industries commonly use floating oil skimmers in storage tanks?
Floating oil skimmers are commonly used in refineries, power generation facilities, industrial wastewater systems, bulk storage operations, and petrochemical facilities where continuous tank oil removal is required.
Does the system require frequent maintenance?
Constructed from durable 304 or 316 stainless steel and featuring few moving parts, the 3F360-GCS™ requires minimal maintenance and delivers dependable long-term performance.
