Pioneering Sustainable Solutions for the Energy Industry

​

At Legasea, we're revolutionising the way the energy industry approaches waste management through our innovative circular economy solutions. Operating under SEPA Waste Management License WML/L/1195912, we specialize in the treatment of waste including offshore waste, with a focus on refurbishing and reusing subsea equipment rather than disposing of it and manufacturing new.

​

Our Sustainable Approach

 

Legasea's waste management service transforms what would traditionally become waste into valuable resources. As specialists in electrical, hydraulic, and mechanical engineering services, we recover, refurbish, and recertify components from decommissioned subsea equipment, significantly:

​

• Reducing carbon emissions for our global clients

• Cutting costs associated with purchasing new equipment

• Shortening lead times for critical components

• Supporting the transition to a sustainable future for the energy sector

​

The Environmental Impact

Quantifiable Carbon Savings

 

Manufacturing new equipment generates substantial carbon emissions. By reusing existing components, we deliver measurable environmental benefits:

• A typical Subsea Tree weighs approximately 45 tonnes

• Reusing one tree saves approximately 82.4 tonnes of CO2 emissions through avoiding primary steel production alone

• With approximately 850 trees installed in the UK North Sea, this represents a potential carbon reduction of up to 70,000 tonnes

​

Breaking the "Use Once and Dispose" Cycle

 

Our innovative business model challenges the status quo of the oil and gas industry's traditional approach to equipment. Instead of single-use disposal, we create a sustainable cycle where valuable components are given new life, reducing:

​

• Raw material consumption

• Energy used in manufacturing

• Waste sent to landfill or scrapping facilities

• The overall carbon footprint of the energy sector

​

Our Waste Management Process

​

Under our SEPA Waste Management License (WML/L/1195912), we follow a comprehensive process to ensure maximum recovery and minimum environmental impact:

​

1. Receipt and Documentation

 

All equipment entering our facility undergoes thorough documentation and assessment, including:

• Preliminary Materials Inventory review

• MSDS sheets verification

• Marine Growth Assessment Reports review

• Shore to Store Goods Receipt checklist completion

 

2. Cleaning and Marine Growth Removal

​​

• Conducted in our specialized test pit with complete containment

• All waste water and removed marine growth properly managed

• Professional waste management contractors handle all removed materials

​

3. Making Equipment Safe

​

• Testing for pressure and fluids

• Safe removal and containment of any remaining substances

• Proper handling according to MSDS guidelines

• Professional disposal of all waste fluids

​

4. Disassembly and Component Recovery

​

• Systematic breakdown of equipment

• Segregation of reusable components

• Sorting of recyclable metals by type

• Professional processing of all waste materials

​

5. Refurbishment and Recertification

​​

• Ultrasonic cleaning of components

• Comprehensive testing and quality control

• Full recertification to industry standards

• Integration into inventory management system

​

Business Models to Suit Your Needs

​

We offer two flexible approaches to handling decommissioned equipment:

​

Model 1: Client Retention of Ownership

​

• Equipment is treated as maintenance/repair items rather than waste

• Components are refurbished and returned to your inventory

• Full traceability and documentation maintained throughout

​

MOdel 2: Transfer of Ownership to Legasea

​

• We take ownership of equipment defined as waste by clients

• Components reach "end of waste" status after refurbishment and recertification

• Refurbished products are marketed globally

• You benefit from reduced disposal costs and improved environmental credentials

​
