Under Water Explosive Shock Testing (UNDEX) Of A Subsea Mateable Electrical Connector, The CM2000

The Under Water Explosive Shock (UNDEX) test is an important step in certification for submarine service. It demonstrates the ability of a component or system to withstand a near by underwater explosion as may be encountered in a field deployment without compromising function or safety. The UNDEX test exposes the device under test to a controlled underwater explosion of known force and orientation. The understanding of the set-up and test procedures encountered in the UNDEX test will help engineers to prepare for and design products able to withstand this testing and gain acceptance for use in military submarine service as well as in general oceanographic applications.

Advancements in the technology of subsea-mateable connectors have enabled the development of increasingly sophisticated subsea systems and simplifies the installation logistics and construction of those systems. The operation and maintenance of such systems has also become much less expensive due to the availability of this technology. As with any new technology, it's acceptance into common use is enhanced by a thorough test and qualification program. The aim of such a program is to prove a product fit for purpose by accurately simulating the actual or even worst-case conditions the product will encounter in use. Exposure to explosive weapons is just such a "worst" case to be considered for systems operating on naval warships. Torpedo and mine damage experienced in World War I proved the danger posed by these weapons and efforts were made to understand the effects of under water explosions with model experiments. World War II was fought with more sophisticated weapons, and even non-contact explosive weapons were able to disable naval vessels. Simulation and direct experimentation on the effects of underwater explosions are undertaken to demonstrate the ability of vessel structures and components to withstand these conditions. The Under Water Explosive Shock Test (UNDEX) is such a test intended to certify components fit for use aboard fleet naval vessels. Passage of this and other environmental tests verify that a component will reliably perform the intended function while ensuring the safety of vessel and crew carrying that component or system.
