Cylindrical Oil-Water Separator for Offshore Wind Farms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil-water separators for offshore wind farms face issues such as excessive water storage leading to structural stress, energy consumption from insulation and heating, and incomplete separation of oil and water, especially in cold temperatures and during emergencies.
Innovation Solution
A cylindrical oil-water separator with distinct oil and water storage compartments, a partition plate, and strategically positioned drainage and vent holes, allowing for two-stage separation and reducing the need for insulation and heating at the accident oil tank, ensuring efficient oil collection and water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the accident oil tank is always filled with water for oil-water separation, then oil and water can be separated, but the weight of the platform increases significantly
Solution Approach 1:
The system is divided into two separate units: a portable oil-water separator and a stationary accident oil tank. The separator handles the separation function while the tank only stores oil, eliminating the need to fill the tank with water for separation purposes.
Solution Approach 2:
A portable oil-water separator is introduced as an intermediary device between the oil discharge source and the accident oil tank. This separator performs the oil-water separation function externally, allowing the accident oil tank to remain empty or contain only oil.
2Reliability
If insulation layer and electric heating equipment are arranged at the accident oil tank to prevent freezing, then the oil tank can maintain separation function in cold temperatures, but time and energy consumption increase
Solution Approach 1:
The freezing protection function is segmented from the accident oil tank and applied only to the portable oil-water separator. This reduces the total energy consumption since the separator is smaller and can be moved to warmer locations during cold periods.
Solution Approach 2:
The oil-water separator is designed to be portable and movable, allowing it to be relocated to warmer areas during cold temperatures to avoid freezing issues, eliminating the need for permanent insulation and heating installations.
3Device complexity
If only one stage of oil-water separation is performed, then the structure is simple, but water discharged may be mixed with oil droplets
Solution Approach 1:
The separation process is divided into two stages: a portable separator for initial separation and a secondary separation system (either another portable unit or a sedimentation chamber) for final clarification. This ensures complete separation while maintaining operational simplicity.
Solution Approach 2:
The two-stage separation system operates continuously, with the first stage providing rapid separation and the second stage ensuring complete oil-water separation. This continuous multi-stage process guarantees high separation quality without interrupting operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution maintains an empty accident oil tank, reduces energy consumption, and achieves thorough oil-water separation, preventing environmental disasters and ensuring reliable operation even in cold conditions.
Implementation Method 1
a partition plate between the two compartments... oil storage compartment... water storage compartment
Implementation Method 2
An oil drain pipe is arranged on a side of the oil storage compartment, and the oil drain pipe is connected to an accident oil storage tank
Implementation Method 3
A water drain pipe is arranged on a side of the water storage compartment, and the water drain pipe extends to a bottom of the water storage compartment

AI summary
Disclosed is an oil-water separator for offshore wind farms. The separator is arranged between an oil drain pipe and an accident oil tank, and has a cylindrical structure, and includes an oil storage compartment, a water storage compartment and a partition plate between them. The disclosure can ensure that the accident oil tank is empty under normal operating conditions so that a platform weight is reduced; and an insulation and an electric heating treatments are only performed at the oil-water separator to save insulation project quantity and energy consumption for heating; and a two-stage oil-water separation is achieved in the oil-water separator to avoid mixing oil droplets into water discharged from a water outlet.
