Flintstone Technology

What Flintstone Technology does

Flintstone Technology Ltd is a specialist mooring systems engineering company headquartered in Dundee, Scotland, founded in 2012 by Andrew Clayson. It designs and manufactures mechanical components used to anchor floating production and storage vessels, buoys, and offshore wind turbines to the seabed. The proprietary product portfolio is organized around three families: connectors (the ROV-operable Buoy Turret Connector that enables mid-water pull-through mooring line connection/disconnection without deck equipment, and the self-aligning Subsea Mooring Connector for seabed anchor points), tensioning devices (the In-line Mooring Tensioner that moves tensioning operations off the vessel hull, a Compact ILMT variant, the Hull-Mounted Tensioner, and the suction-pile-mounted Compact Underwater Fairlead), and accessories including Lever Arms, Uni-Joints, H/Y/Twisted Links and a patented dual inductive coupler for power and signal transfer across rotating mooring joints. All products are designed to DNVGL-OS-E302 standards and supported by an in-house test facility in Dundee offering proof load, fatigue (2700kN), friction (250t) and hydrostatic (200bar/2000m) testing.

The company serves major offshore operators in oil and gas (Shell on Vito and Stones, Tullow Oil on the Jubilee turret emergency response, Equinor on Mariner, Kraken and Hywind, Modec on FPSO Kwame Nkrumah) and in floating LNG and offshore renewables (Moheshkhali LNG re-gasification project in Bangladesh, Hywind Scotland). Revenue is generated primarily through bespoke hardware sales on multi-year project contracts, supplemented by testing services from the Dundee rigs and engineering consultancy. Distribution is a hybrid of direct enterprise field sales to operators and a strategic partnership with MacGregor that delivers total mooring system solutions on a global basis. The company is privately held and has been majority owned by the Belgian industrial group Bekaert since December 2024.

Functional benefit

Products and services

• Buoy Turret Connector (BTC) ROV operable pull-through mooring connector using a sheave system that allows the male to be pulled into the female mid-water with pin insertion by ROV, enabling mooring line connection and disconnection without deck equipment. Features 2 axes of rotation, small footprint, and is available for chain, wire and polyester ropes.
• Subsea Mooring Connector (SMC) Self-aligning male and female forging connector for connecting mooring lines to seabed anchor points using a ROV-inserted load pin. Replaces ball and taper systems with a simpler, more robust solution suitable for chain, wire, or rope connections, with automatic backup locking mechanism and high fatigue resistance.
• In-line Mooring Tensioner (ILMT) Mooring tensioner that performs tensioning operations away from the vessel hull, providing increased safety and eliminating the need for chain jacks and chain lockers. Features counter-weighted chain stopper, non-metallic bearings, and lightweight cast design scalable to meet DNVGL-OS-E302 standards.
• Hull-Mounted Tensioner (HMT) Traditional hull-mounted tensioner combining chain wheel with the inboard pivot of a uni-joint. Can be used for hull-mounted or deck edge connections, with 5-pocket chain wheel and pivoting chain stopper body.
• Compact Underwater Fairlead (CUF) Fairlead designed for mounting on top-loaded suction piles to enable mooring line tensioning at seabed. Features dual-axis joint to accommodate mooring line motions and can be combined with SMC and BTC for complete mooring line replacement capability, with pocketed or plain chain wheel options.
• Compact Tensioner (C-ILMT) Compact, lighter weight in-line tensioner evolved from the Vito project design with improved geometry that eliminates 'tipping' issues and provides smoother tensioning operation.
• Testing Services High-load testing services from Flintstone's Dundee test base including proof load testing, fatigue testing, friction testing, hydrostatic testing, and bearing qualification, with test rigs available for hire for any structural testing requiring high loads.
• Mooring Engineering Consultancy Design and product solutions consultancy spanning from initial concept through prototyping and production, leveraging the team's broad spectrum of design and production experience in high integrity mechanical engineering for offshore mooring applications.

Expansion highlights6 records

Broad incumbents

• MacGregor: MacGregor is Flintstone's strategic consortium partner for full mooring system delivery, but also offers its own mooring, deck machinery, and offshore load handling portfolio. Overlap with Flintstone on integrated mooring tenders and a critical channel partner.
• SBM Offshore: SBM Offshore is a major FPSO contractor offering integrated turret and mooring system design. While primarily a full FPSO provider rather than a mooring component specialist, its in-house mooring capabilities overlap with Flintstone's addressable scope on major FPSO tenders.
• Bluewater Energy Services: Bluewater designs and operates FPSO and FSO vessels with proprietary disconnectable turret mooring systems. Comparable mooring technology scope and FPSO operator customer base, though operates at a larger EPC scale than Flintstone.

Direct peers

• InterMoor (Acteon): InterMoor provides mooring installation, engineering, and marine services for offshore operators. While more services-oriented, it directly competes for mooring system delivery and adjacent to Flintstone's project execution scope on FPSO and floating wind installations.
• Vryhof: Vryhof (now part of Bridon-Bekaert) is a leading global supplier of offshore mooring systems, anchors, and chain products. Directly comparable mooring hardware portfolio and serves the same FPSO, FSO, and semi-submersible customer base as Flintstone.
• Delmar Systems: Delmar Systems designs, installs, and services offshore mooring systems for MODUs, drillships, and floating production units. Directly comparable to Flintstone for mooring hardware supply and field installation support across oil & gas and emerging floating wind markets.
• Bridon-Bekaert: Global leader in mooring ropes, chains, and offshore solutions. Now a fellow subsidiary of Bekaert alongside Flintstone. Overlapping customer base across offshore oil & gas and an obvious partner/competitor dynamic for integrated mooring system tenders.
• SOFEC: SOFEC (a MODEC group company) designs and manufactures turret mooring systems, CALM buoys, and offshore loading systems. Directly competes with Flintstone in spread-moored and turret-moored FPSO segments and is a leading integrated mooring system supplier.
• First Subsea: First Subsea manufactures offshore mooring connectors, bend stiffeners, and load reduction devices. Directly competes with Flintstone's BTC and SMC product lines and serves the same FPSO, FSO, and semi-submersible customer base (Taylor was previously Engineering Manager there).
• BallTec: BallTec designs and manufactures mooring connector solutions for offshore and marine applications, including the well-known SeaThrust ball-and-taper connector. Direct competitor to Flintstone's SMC connector for seabed mooring terminations.
