Abstract:
An autonomous underwater system for effecting long-term monitoring, in continuous, onsite and with a wide range of parameters relating to the sea environment, consisting of a multidisciplinary underwater station and an autonomous underwater vehicle, co-operating with each other to allow various kinds of environmental explorations. In particular, the present system represents a solution for monitoring the environmental impact of offshore activities, characterizing unexplored sites, supporting the management of polluted areas, monitoring the integrity of structures installed in underwater environments and verifying the possible intrusion of third-parties in an area to be monitored. The autonomous underwater system for environmental monitoring (100) comprising a multidisciplinary underwater station (101) equipped with onboard instrumentation (202), at least one autonomous, modular underwater vehicle (102) movable inside an area to be monitored (107) along an assigned route 106 and at least one external instrumental modulus (206) which can be connected to said vehicle (102), wherein said multidisciplinary underwater station (101) comprises a docking area (204), an interface system (220), an equipping system (207) for supplying the vehicle (102) with instrumental modula (206) and a management system (201). Said autonomous modular underwater vehicle (102) belonging to the autonomous underwater system for environmental monitoring (100) can be equipped with onboard measurement sensors (311), and comprise at least one main thruster (302), at least one auxiliary thruster for fine positioning (305, 306, 307), a hull (301), at least one electronic control modulus (313), at least one energy reserve (312), at least one connection system (308), and means for attaching (317) at least one instrumental external modulus (206), wherein said instrumental external modulus (206) is equipped with at least one measuring sensor (314). A further object of the present invention relates to a method using a multidisciplinary underwater station (101), an instrumental external modulus (206) and an autonomous modular underwater vehicle (102) for collecting data relating to the underwater environment in relation to time, and providing, after processing, a four-dimensional vision of the underwater environment monitored.

Abstract:
An arrangement and a method for installing a propulsion unit to a hull of a ship. The propulsion unit comprises an upper part of the propulsion unit attachable to the hull of the ship and a lower part of the propulsion unit where to a propeller shaft is rotatably supported, and the upper part of the propulsion unit having flanges to attach the flanges tightly to the hull, and wherein there is an aperture in bottom of hull where to the propulsion unit is to be installed. The arrangement comprises a plurality of watertight covers (32, 34) covering openings (24, 28) in the bottom of hull and a plurality of watertight covers (50, 52) covering openings (46,48) in the top of the upper part of the propulsion unit, wherein the arrangement comprises a removable hull-side cover (32) covering at least the opening (24) under it, and at least one removable propulsion unit side cover (50) covering the opening (46) under it and facing the opening (24), and the removable covers (32, 34, 50, 52) are bolted from the hull-side.
Abstract:
A system for providing mechanical and electrical power in a vehicle or other engine-driven platform includes a first engine having a first power rating and a second engine having a second power rating that is less than the first power rating. The system further includes a first generator (for example, an alternator) for generating electrical power for a load operation (such as vehicle propulsion), and a second generator (for example, a DFIG) for generating fixed frequency electrical power; both generators are operatively connected to and powered by the first and/or second engines. The first and/or second engines may be selected to power the first generator for generating power for vehicle propulsion or another load operation depending upon situational power requirements of the engine-driven platform.
