marine breakaway couplings During the late 1960s and early 70s the use of Hose Breakaway Couplings (MBC) at offshore terminals was considered by many operators as a "nice to have" item in their SPM or MBM package, in fact some even thought of an MBC as "another thing to go wrong"!
The Marine Breakaway Coupling (MBC) is a device installed into hose transfer systems at offshore tanker discharging or loading terminals. The MBC is designed to prevent oil spills and protect the transfer system from damage in the event of a tanker breakout or an excessive pressure surge.
How does a Dry Break Coupling work? This coupling simply works by turning the hose unit 15degree clockwise locking the units together. The valves are still closed and are not opened until a further rotation has been performed and then the product flow is guaranteed.
Feb 27, 2018· The center hubs used on outboard motors and sterndrive boat propellers are separate from the boat propeller itself. There are two types of hub systems used. The oldest type has been around for over sixty years and is made of rubber that surrounds a metal spindle that goes on the propeller shaft. The rubber hub is larger in diameter than [.]
The MIBREAK, MIB petal type Marine Breakaway Coupling, is a passive safety device that protects a flexible hose string (floating or submerged) from an excessive axial load, a surge pressure, or a combination of the two.. The MIBREAK is designed for a 25 years life subject to periodic maintenance and is maintenance free for 5 years. The key features of the "MIBreak" include:

Marine Breakaway Couplings – Protecting Against the Inherent Dangers of Fluid Transfer in a Marine Environment. Despite the ongoing development of pipelines across many parts of the world, the transportation of fluids such as crude oil from their source to their destination is still largely done via oceanbound tanker.
The cryogenic breakaway couplings have three external break bolts. In the case of axial tension all the bolts take up the force corresponding to the break force on the hose with a safety margin. Nonaxial forces concentrate the tension forces more strongly on one bolt, so that the safety breakaway coupling reacts in a natural
Well, a Marine Breakaway Coupling refers to a device fitted with a flexible hose pipe, and it parts whenever an axial load or internal pressure surges above a certain fixed value. The couplings have differing designs based on the roles they play in either liquefied gas transfer or oil transfer systems.
The NTS®PUM is a Marine Breakaway Coupling, also known as a Marine Breakaway Coupler or Emergency Release Coupler. Developed by our company especially for harsh marine conditions, its robustness and vigorous resistance to saltwater corrosion makes it the ideal breakaway coupling for offshore applications.
GTAC Engineers can also work with a nearby facility recommended by the operator. Local repair. Not only can a Gall Thomson local workshop perform the reset or refurbishment of your Marine Breakaway Coupling, but in most instances it can also perform reclamation work to units that have been damaged due to impact, corrosion or violent activation.
Breakaway couplings are designed for installations where, due to accidental circumstances, hoses or pipe work systems can be subject to tensile loads, leading to failure. The insertion of a Breakaway coupling can prevent pollution, fire or chemical hazards, product loss or damage to plant and equipment.

The safety breakaway valve consists of two halves, each with a valve that has an Oring seal. AFTER emergency disconnect When the safety breakaway couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment. 8" US Gallons (GPM)
Jun 20, 2016· How Does a marine breakaway Coupling Work? Basically, the marine breakaway Coupling is designed to produce an identified safe parting point in a hose transfer system. When the MBC''s preset parting load is exceeded, it activates; the valves close and shut off the line either on one side or both sides of the parting point as required.
The KLAW Marine Breakaway Coupling is designed specifically to resist those bending moments and torsional forces expected from floating wave motions and the rigours of the marine environment. The design of the KLAW Marine Breakaway Coupling therefore prevents premature activation of the unit and protects the Breakstuds from fatigue.
