Extending the life of subsea assets through reuse, refurbishment, and recertification—reducing lead times and supporting a sustainable energy future.
The Legacy Locker encompasses the following while meeting the circularity gaps:
- Extends the life of subsea assets by refurbishing, recertifying, and repurposing obsolete equipment, offering a sustainable alternative to new manufacturing.
- Reduces project lead times and enhances operational continuity through rapid access to critical components via a shared asset scheme.
- Supports ESG and net-zero goals by minimising waste and quantifying carbon savings associated with equipment reuse and remanufacturing.
- Addresses industry-wide obsolescence challenges by providing flexible, innovative, and cost-effective solutions beyond traditional OEM support.
Supporting Long-Term Asset Life for OEM Equipment
Legacy Locker is a trusted solution when original equipment manufacturers (OEMs) are no longer able to support operational needs.. J+S Subsea delivers tailored solutions that extend the life of critical subsea assets. When OEM support ends or components become obsolete, Legacy Locker steps in—providing refurbishment, reverse engineering, and recertification services to keep your equipment running reliably and efficiently, while minimising disruption and downtime.

Backed by deep expertise in subsea design and manufacturing, our team delivers innovative, dependable results tailored to each client’s needs. We focus on long-term asset performance and integrity. Our trusted relationships with major operators are built on consistent delivery and a shared commitment to extending the life and value of critical subsea equipment.
Sustainable Solutions Through Reuse and Recertification
Legacy Locker is built on a commitment to sustainability, offering practical solutions that extend the life of your subsea equipment. Through remanufacture, recertification, or reuse of existing components, we help restore operational performance while minimising downtime. Our approach not only supports asset integrity but also contributes to carbon reduction and cost efficiency. All sustainability gains can be clearly reported to support your ESG objectives and demonstrate environmental responsibility.
Commitment to Net-Zero
Legacy Locker plays a key role in supporting the energy transition by enabling continued oil and gas production while advancing net-zero goals. Our solutions help operators maximise the value of existing assets—even in late-life or declining fields—by maintaining performance and extending operational life. We contribute to a more sustainable industry by reducing waste, minimising environmental impact, and supporting long-term asset efficiency as part of a responsible path toward net-zero.
