In order to facilitate the disposition of multiple noise measuring points in a distributed manner, this underwater noise monitoring device is provide with: a processing unit in which, by using data which was acquired using optical fibers installed underwater or on a bottom of water and which indicates noise or vibration at the position of each of the optical fibers, a statistical value of the amount of noise or vibration is derived at the time and the place when/where the data was acquired; and an output unit that outputs the statistical value.

When on-water control means 20 having moving means and capable of moving near a water surface controls a multiple underwater vehicles 30 which cruise in water, the moving means 23 controls movement of the on-water control means 20 such that the multiple underwater vehicles 30 are located in a control region X where the on-water control means 20 can position the multiple underwater vehicles 30 utilizing acoustic positioning means 24 provided in the on-water control means 20. According to this, it is possible to deploy and operate the multiple underwater vehicles in water and safely and efficiently carry out survey operation and the like such as water bottom exploration.

An adapter includes a waterproof container, a photoelectric conversion device housed in the waterproof container and connected to an optical cable, and an attachment structure provided at the waterproof container, for use in detachably attaching the adapter to an ROV.

A sensor suspension system for use in an underwater environment comprises a sensor (e.g., vector sensor) and a framework comprising a plurality of support structures, and a plurality of compliant devices that suspend the sensor within an inner volume of the framework. The plurality of compliant devices facilitate a symmetrical sensing response of the sensor in three degrees of freedom when deployed in the underwater environment. The framework is moveable from a collapsed position to an expanded position. A plurality of sensor suspension systems can be tethered together into a sensor array by a deployment control system operable to release a buoyant device, tethered to the sensor suspension systems, that vertically positions the plurality of sensor suspension systems into the sensor array. The buoyant device can cause each framework to expand via pulling force through the tethers upon release of the buoyant device.

A subsea assistance system for supporting saturation diver operations includes an unmanned underwater vehicle (UUV) such as an observation remotely operated underwater vehicle (ROV) that can be flown to a subsea worksite, and various items of ancillary electrical equipment that are connected or subsea-connectable to the UUV or to a skid forming part of the UUV. Those items can include any of: a hand-portable subsea display that displays an image to a diver communicated from the UUV, which image can be generated or enhanced underwater and/or by surface support; a subsea camera that captures subsea image data for communication to the UUV and from the UUV to surface support; and a selection of electrical power tools for performing subsea tasks. Fast-acting protective devices protect divers when using high-voltage wet-mateable subsea connectors on the UUV.

A removable and reversible sliding mount for a marine transducer has a C-shaped mounting channel affixed to the transom of a boat. A closed bottom end of the C-shaped mounting channel is proximal to the bottom of the boat and an open top end of the mounting channel is at or above the water line of the boat. A mounting board having a handle at one end and a transducer at the other end may be slid into the mounting channel so that the transducer is positioned just below the bottom of the boat. The mounting board may in be inverted so that the transducer is positioned above the waterline of the boat. A locking mechanism may be used to secure the mounting board in the mounting channel. The mounting board may also include cable guides to secure a transducer cable along its length.
