Cel This project aims at designing, manufacturing and demonstrating, by land, shallow and deep water tests at sea, an Integrated Deep Water Operative System for light and heavy underwater works on the sea bottom (1,500 m). These are mainly demanded by installation, maintenance and removal of hydrocarbons production structures, subsea systems, pipelines and cables and for the recovery of wrecks, sunk objects or cargoes.The overall goal is to make available a flexible system able to support and cooperate with ROVs, eventually incorporating itself advanced manipulators, but above all featuring high force reaction capability, thanks to its contact with the sea bottom. These features are required by typical heavy duty sea bottom tasks of industrial interest, which at present are performed only with direct support by surface vessels, lifting lines and ROTs (Remotely Operated Tools). Deep water operations in particular would take substantial advantage from this system.The main result of the project is the realization of the vehicle with its surface equipment; the vehicle includes the tractor, complete with its electrohydraulic system and instrumentation, and the following tools : the backhoe with different "end-effectors" (i.e. shovel and rock hammer), the winch, the crane with its grabber, a dredging tool with suction pump and cutter head, an oil isolated hydraulic power unit (IHPU) and a sea water IHPU.The surface equipment includes : an umbilical winch (comprising its power pack, slip-ring assembly, local control and 1700 m umbilical cable with bend restrictor, floats and mechanical connector) and three conteinerized modules for the control room, the power distribution and the air compression (plus workshop/spare parts container).The results will also include design of interfaces for further tools such as a carry on eye-ball, a scraper, a manipulator, a dozer, a penetrometer and a flowline trencher.The Integrated Deep Water Operative System Object of this project includes two main physical subsystems: the Surface Operating System and the Modular Tracked Vehicle comprising different tools.The project will concentrate on the key subsystems of a modular concept based on existing technologies, some of which already applied to this field, but achieving a substantial improvement in terms of work capability, flexibility, standardisation and range of operational conditions. The Surface Operating System is composed of the following parts: power distribution, control room; air compression, umbilical and umbilical winch, mechanical/electrical interface to the vehicle.The Modular Tracked Vehicle, which is the prime mission subsystem, is made by the following main elements: structural frame; two track assemblies directly driven by hydraulic motors with two lightweight nylon tracks with large bearing surface; two hydraulic power generation units, each with 150 kW electric motor; the hydraulic manifold and distribution systems; thrusters to allow the alignment prior to landing onto the sea bottom; the Subsea Electronic Unit which communicates with the surface control and shares with it the control and monitoring functions; the instrumentation and the electric interconnection system including the navigation instrumentation (one sonar, 2 TV cameras on pan & tilt units and one on a fixed support).
