Patent number: 9488203Abstract: The described embodiments provide a subsea connector that is a quickly deployable and reusable. The subsea connector comprises a male and a female assembly that can be connected and disconnected. The male assembly includes a shaft, a sleeve that surrounds the shaft, and bars that are connected to the shaft and are configured to rotate about one axis. The female assembly includes a receptacle into which the male assembly can fit. Once the male assembly is inserted into the female assembly, the bars can rotate into such a position that the male and female assemblies are connected together. The bars can also be rotated such that the male and female assemblies can be disconnected.Type: GrantFiled: March 5, 2014Date of Patent: November 8, 2016Assignees: Enginuity Inc., Oceanside Equipment LimitedInventors: Gleb Sekretta, Benjamin Garvey, Lee Babin, Daniel Horne, Louis-Phillipe Manuge, Steven Doiron, Martin Gregory Maloney, Alastair Trower
