The Importance of a Marine Breakaway Couplings

Marine Breakaway Couplings (MBC’S) are safety devices used in establishments where liquids are exchanged between vessels, usually under a lot of pressure. This includes organisations in which liquids like crude oil are transported via ocean-bound tankers. The MBC’s are used to avoid spillage. Lack of this safety device, which breaks liquid exchange framework, can cause harm to workers, and destroy equipment and facilities in case of spillage. This is particularly important since these fluids are flammable and pollutants like crude oil are hard to clean if there is an accident.

Benefits of Marine Breakaway Couplings

Marine Breakaway Couplings are used for loading tankers with oil at sea or discharging cargo in ports. They are also used when loading vessels with byproducts of oil such as liquid petroleum gas. More establishments are increasingly using MBCs since more installations have moved to other countries meaning they have to transport the product across countries. The MBCs provide safety during transit in harsh environments in sea that pose more risk. The device prevents accidents or mitigates the effects of two types of accidents. One of these is to prevent hose rapture or failing of connections brought about by physical strains- for instance, mooring failure causing a tanker moving from its location. If this happens, the flow of fluid is instantly stopped before causing further damage. Secondly, it provides protection against an unexpected increase in pressure in the hose which could cause failure in joints and fittings, causing spillage of oil.

How to Operate MBC’s

To ensure the devices operate properly, there are several factors to be considered during installation and use. For example, you should train your employees on how to use MBCs so that the devices are not unnecessarily activated due to inadequate understanding of the workers or poor installation. It is also important to inform manufacturers of hoses and other equipment that you will be using MBC’s. They will factor this when deigning and configuring their products to make sure the products work together properly. It is equally important to avoid handling hoses with attached MBCs by vessels which exceed the device’s load tolerance. If you use the device correctly, the system should last you for 15 years.

What to Consider When Choosing Couplings for Installation

Since the device is expected to work optimally for over a decade, it’s important that the right type of MBC be chosen. The manufacturer should consider expected hose load before recommending the suitable specification to meet the client’s need. There are two main types that they could recommend for you. This includes Petal Valve MBCs which have full sized bores. These are the best choice for liquids like crude oil. The second one is the Flip-Flap MBCS that offer low level head loss, making them suitable for lower viscosity fluids such as liquid petroleum gas. Other facts that you should consider include:

  • The device should be reusable.
  • The MBC’s movable cut off speed should match its working conditions. You should also be able to adjust it without harming the device
  • It should be located in a place where it won’t come in contact with liquid being exchanged to increase its life span.
  • It should be as light as possible to allow you to easily work with.


All companies that transport crude oils and other liquids across shores need MBCs. Therefore, purchasing and installing the device is important. You should also ensure that it’s properly maintained by a representative from the manufacturer’s company to avoid any incident. Additionally, workers operating the equipment should be able to recover MBCs and hoses after activation to keep the device working optimally for a long time.
