National planners are developing programs for surveying and exploiting the oceans. A decade of international collaboration is contemplated for the 1970's. The focus is on exploitation as contrasted to research, so the major problems will be engineering problems. The disciplines of naval architecture and marine engineering, and the technologies of ship designing, shipbuilding and ship operating will feature in this future national-international exploitation of the world's oceans. The Society of Naval Architects and Marine Engineers has espoused the broader domain of ocean engineering for the future scope of the Society's activities. Policies and plans have been completed. Problem areas and possible SNAME activities have been identified and assigned for action. An Ocean Engineering Advisory Group has been operating for two years in carrying out this work and will continue to maintain and control an active SNAME participation in ocean engineering. This paper summarizes the aforementioned plans and activities and mentions 19 interesting ocean engineering focal projects which might be useful to advance our capabilities for exploitation of the ocean resources.

An alternative teaching-learning methodology for the subject "Hydrodynamic, Resistance and Propulsion" in Degrees concerned with NAval Engineering, is presented. The goal of the pedagogical approach is the acquirement of appropiate skills related to the ability of analyzing and designing different types of ships. The blended learning concept is employed, including the supervised learnin as key ingredient. The roles of both Information and Communication Technologies (ICT) and Computational Fluid Dynamics (CFD), as educational tuools, are some specific features of the methodology. A pedagocial method that involves project based learning, using CFD, is applied. The evaluation of the student satisfaction is conducted by questionaries.

With a renewed global focus on anti-submarine warfare (ASW), the United States Navy will increasingly rely on unmanned underwater vehicle (UUV) technology to serve as a cost-effective force multiplier. Modern UUV development necessitates a uniquely constrained, iterative approach to the traditional submarine design spiral. Considering a broad spectrum of customer-generated requirements, the UUV conceptual design process applies the best practices of naval architecture, marine engineering, ocean engineering, systems engineering, and submersible design. This paper provides an assessment of the traditional approach to the UUV design and development process. Specifically, this paper analyzes the design philosophy for modern UUVs, provides a design framework for the UUV conceptual design process, and details specific recommendations to encourage innovation in the subsea realm.

In the last year, the Department of Naval Architecture and Marine Engineering of Genoa University (now Department of Naval Architecture, Marine Technology and Electrical Engineering) collaborated to the design of the propulsion automation of two different naval vessels; within these projects the authors developed different ship propulsion simulators used to design and test the propulsion control schemes. In these time-domain simulators, each propulsion component is represented by a specific mathematical model, mainly based on algebraic and differential equations. One of the key aspects of the propulsion simulation is the engine dynamics. This problem in principle can be dealt with models based on thermodynamic principles, which are able to represent in detail the behaviour of many variables of interest (engine power and speed, air and gas pressures, temperatures, stresses, etc.). However, thermodynamic models are often characterized by a long computation-time and moreover their development usually requires the knowledge of specific engine information not always available. It is generally preferable to adopt simpler simulation models, for the development of which, very few kinds of information are necessary. In fact, for the rapid prototyping of control schemes, it is generally more important to model the whole plant (in a relatively coarse way) rather than the detailed model of some components. This paper deals with simple mathematical methods, able to represent the engine power or torque only, but they can be suitably applied to many types of marine engines in a straightforward way. The proposed simulation approaches derived from the authors’ experience, gained during their activity in the marine simulation field, and they are particularly suitable for a fast prototyping of the marine propulsion control systems. The validation process of these particular models, regarding a Diesel engine, a marine gas turbine and an electric motor, is illustrated based on the sea trials data and engine manufacturers’ data.

Mohd Ridwan, Eko Yulianto, in paper competency of naval architecture diploma program on Indonesian maritime industry explain that Shipbuilding engineering professionals is part of the leading maritime industry is expected to become the motor of development of national maritime fleet in the implementation of cabotage (Impres No.5, 2005), this will reduce foreign exchange spending nearly 99 trillion rupiah per year due to the use of foreign fleets, and the creation of new jobs as a supporter of the maritime industry. So the presence of workers who have competence in the field of shipbuilding (ship building, naval architecture, marine engineering enginerring and maritime transportation) is urgently needed and their capability to compete with other countries that previously controlled the sea as a source of national income should be the Indonesian government's attention.
