Legacy Locker

J+S has developed this portal for refurbished and new subsea Legacy equipment where you can buy, sell or trade your unwanted stock.

Leading the way in the Oil & Gas industry

J+S realises the economic value of refurbishing existing, unwanted capital equipment. Legacy Locker is the open industry portal for the re-manufacturing, recycling and up-cycling of subsea equipment.

J+S is leading the way in the Oil & Gas industry to optimise the value of existing, unwanted capital equipment, combating the continued downturn in the offshore market.

J+S is committed to adjusting economic, social and environmental behaviours to build a resourceful and sustainable future. To support this goal and to avoid large quantities of fully functioning equipment simply being scrapped, Legacy Locker was launched.
