The HOT MAKE HOT BREAK (HMHB) has been deployed globally for 2 decades. It is integrated on to permanent and temporary subsea architecture enabling quick and safe connection for well intervention.
Secc design, test and develop Coupling solutions individually or integrated into bespoke solutions such as: Skids, Frames, Pannels, Mudmatts, Gimbals and Turrets.
The HMHB is the world’s leading high pressure Quick Connect Disconnect (QCDC) and Emergency Quick Disconnect (EQD). It provides Subsea well operators with an integrated single point coupling solution for routine connections and emergency disconnections.
Full Bore – Zero Spill – Zero Leak – Pressure balanced Couplings
The HMHB combines the passive and active functions in one coupling reducing capital equipment costs, downtime.
The dual feature is facilitated by “plug and play” pressure balanced geometry. The HMHB is connected and disconnected in one function when an axial push or pull is applied. Without additional fasteners, locks or catches.
The MIDLINE WEAK LINK (MLWL) offers passive breakaway to set a “break load” anywhere in the hose string.
Operators are looking to reduce the complexity and increase the efficiency of hydraulic interventions operations. Secc’s HMHB enables operators to hydraulically access subsea wells from a range of subsea production assets and provides a permanent ROV operable, plug and play QCDC and EQD. This removes the need for a dive spread, reduces the need for large expensive equipment spreads and opens up the opportunity to use “vessels of opportunity” reducing vessel costs. Further, operational weather windows are broadened. The practise of pre-installing a HMHB on a subsea manifold to shallow hydraulic intervention from a DP-2 vessel has been undertaken by Secc’s clients since 2013.
Secc’s HMHB and MLWL are the go-to QCDC’s and EQD’s for Subsea Riserless Light Well Intervention (RLWI). The technology is used across all LWI applications such as hydrate remediation, acid stimulation and scale squeezes. All the major RLWI OEM’s and service companies use Secc’s products. These companies include all Tier 1 and Tier 2 well intervention service providers. By extension all the major oil companies and the majority of international, national and independent oil companies are familiar with Secc’s technology. It has proven to be the Best Available Safest Technology (BAST).
Secc’s Gimbal and Turret Swivels can provide improved flexibility for coupling connections from Subsea Flowlines to Rigid connections. Whilst offering unapparelled EQD performance.

Secc’s Modular Skid has been deployed for over 15 years supporting RLWI (Riserless Light Well intervention) campaigns on the Agbami Field in Nigeria. This solution, designed and manufactured by Secc integrates 2 x HMHB, Pipe work, Tee-piece, Fabricated Skid, Hoses and HIGHFLOW Hot Stab into 1 skid. This allows the Skid to be placed adjacent to the Intervention package and connected via flying lead, in turn removing weight from the Intervention package. Whilst offering Dual EQD for the downlines and full bore (2”) throughout the Skid.
Early well test vessel: This dedicated vessel has utilised the HMHB on a support shoot. The vessel is controlled by Dynamic Positioning (DP) and manoeuvrers close to fixed structures in a variety of locations and climates. In an emergency event the HMHB protects the flow line – operating as an emergency quick disconnect – and surrounding environment due to its zero loss, zero leak characteristics avoiding spillage.
The quick connect characteristics of the HMHB allows the operator to reset connection via an integrated winch once the free end is retrieved, significantly minimising downtime.
The 90° geometry of the HMHB allows efficient integration into Reel pipe work. Predominately replacing the traditional 90° Elbow where the pipe work enters the Reel drum. The HMHB balanced design allows for non-aggressive controlled activation, even when pressurised. This HMHB was fitted with an interlock, allowing it to be disarmed when the Hose was fully paid out. Allowing for a passive activation to initiate in the event the Hose was over tensioned. Resetting is achieved on the reel without decoupling.
The HMHB mounted on the Reel was used in a series of extended well production tests. Produced hydrocarbons are transferred from a nominally unmanned installation via a 4” hose to the Early Production Vessel. During 12 months of operation the EPV had difficulties controlling the Dynamic Positioning leading to the need to disconnect and reconnect the hose via the HMHB frequently. During these operations no hydrocarbons were released to the environment due to the zero leak, self-sealing nature of the HMHB.
The Four-inch MAXFLOW HMHB (Hot Make Hot Break) protects flowlines running from Lubina Well to the Casablanca offshore oil Platform located in Mediterranean sea, at 45 km from the coast of Tarragona in the east of Spain. This HMHB was adapted to a 45° elbow with a swept neck to allow for a horizontal installation.
The Connector is positioned in the Midline position on 4.5-inch flowlines located on the seabed at 2400 meters. The pressure balanced Coupling allowed for high pressure fluid transfer from well to platform whilst offering unrivalled break loads.
With the Transition Protection disengaged (See Orange Hoop) after installation the Coupling will activate under the lowest of axial forces. Autonomously releasing and isolating the hoses.
The Secc Coupling was installed on this unique system to protect subsea infrastructure during seismic events.
Secc’s Passive Midline Weak Link (MLWL) have been deployed in the pacific for over 12 years. Supporting Well invention and enhancement campaigns for major operators. Protecting downlines during well stimulations and transit between operations.
The Siri Knutsen a former chemical tanker, was converted into a DP2 shuttle tanker in 2013.
The design covered the whole conversion, which involved the installation of a bow loading system (BLS) and all the equipment necessary for the vessel’s new role. In addition, many of the ship’s existing systems were modified, and new stability and damage stability calculations were made.
Secc’s Hot Make Hot Break (HMHB) QCDC was a critical part of the Siri Knutsen conversion. Acting as the Hose End Valve (HEV) and receptacle the 4 inch HMHB allowed for quick and safe connection/disconnection of transfer hose during routine and emergency scenarios. Unlike traditional HEV’s the HMHB offers Full bore, zero spill with integrated impact protection.
