A deep-water submersible system is disclosed. The system can include a pressure vessel and an internal assembly. The internal assembly can include a housing and a wedge lock assembly coupleable to the housing. The wedge lock assembly can include a plurality of wedge members arranged along a longitudinal axis and including end wedge members at each end and one or more intermediate wedge members between the end wedge members. The wedge lock assembly can also include a displacement device along the longitudinal axis and connecting the end wedge members. The displacement device can be actuatable in one direction to move the end wedge members toward one another to displace adjacent wedge members relative to one another in a direction transverse to the longitudinal axis to engage and apply a clamping force to the housing and the pressure vessel. In addition, the wedge lock assembly can include a variable gap compensation mechanism operable to exert a biasing force on the plurality of wedge members to accommodate the relative transverse movement of the adjacent wedge members and maintain the clamping force on the housing and the pressure vessel within a predetermined range as a distance between the housing and the pressure vessel varies.

Disclosed is a capsular-type underwater release lifeboat that can be operated in davit mode, freefall mode and underwater mode. The lifeboat comprised of an outer shell, and fitted inside with engines that aid in forced and normal propulsions of the lifeboat. Two air pockets are arranged in both the ends of the outer shell to sustain underwater pressure and to aid increased buoyancy of the lifeboat. A fixed Emergency Positioning Indicating Radio Beacon (EPIRB) is provided inside the lifeboat for rescuers to easily locate the survivors and a double water tight entrance door is formed on the top portion to resist the underwater pressure. The present invention also provides a method for releasing the lifeboat underwater. The reinforced lifeboat discussed herein shall be deployed on the sea and also underwater in order to rescue the people during a disaster in the sea vessel.

The present invention belongs to the technical field of ocean traffic engineering, and relates to a fabricated ocean tunnel structure with an escape device and an application method thereof. The present invention includes a fabricated ocean tunnel structure and an escape device. the partition plate separates a middle bin in the tunnel, and the escape device is connected into the middle bin; and the escape device includes a rescue capsule, transverse ladders are evenly arranged in the rescue capsule, and a balancing weight block and a rescue equipment area are arranged at the bottom of the rescue capsule. The ocean tunnel structure can be provided with a rescue device during installation, and the safety of personnel escape can be guaranteed; therefore, the safety of the ocean tunnel structure is improved, cost is relatively low, secondary damage to the ocean tunnel structure is not needed.

An apparatus for use with a submerged compartment is presented. The apparatus includes deployable physical connection hardware provided with the submerged compartment. The deployable physical connection allows for a transfer of fluid between the submerged compartment and a region near a marine free surface when deployed. The deployable physical connection hardware comprises a hose in one aspect.
