Dwellop’s work-over units range from standalone solutions, which are mobilised and installed on offshore installations, to cantilevered solutions for jack-ups or liftboats.

All concepts are based on proven technology and bridge the gap between coiled tubing and jack-up / drilling rigs.

Focused on the specified working environment, the company’s designs are based on a redundancy and fail-safe philosophy to increase safety and minimise rig downtime to enable easy access for maintenance and service.

About Dwellop

Originally founded in 1989 as JMC, Dwellop was established in February 2014 as a result of a management buy-out of Rolls-Royce’s well intervention division.

Initially delivering high-quality products for well intervention operations, JMC identified and targeted a market for comprehensive handling systems for workover, P&A and light drilling applications.

Dwellop now provides cost-efficient and high-quality equipment for well intervention operations, in addition to further developing and capitalising on its experience with comprehensive systems such as modular drilling rigs.
