Position of terotechnology, on the other hand, is placed in relation to the economics, life cycle cost and maintenance. The aim is to define terotechnology as optimization process of the ratio between the total effective or potential production of the system and cumulative cost in the lifetime of system. As a static phenomenon the ratio can be optimized apart the market influence and business strategy and policy. The optimization process indispensably includes reliability, adaptability and availability of the system.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

However, in this sea area, the current is fast and the water depth is too deep for diver's work. Therefore, to develop a new system in order to carry out viewing work safely and efficiently was required. An underwater observation system using \"autonomous towed vehicle\" was proposed and the dynamic characteristic of the system was investigated by the basic motion simulation. Moreover, the hydrodynamic coefficients were determined by the results of the towing tank test. After the stability of the towed vehicle was verified by the examination based on the experimental data, the body of the prototype model was manufactured. This paper discusses the total control system of the vehicle including the collision avoidance method with the obstacle. And the result of the field experiment which uses existing AUV (Autonomous Underwater Vehicle) aiming to confirm the feasibility of the U-GIS (Underwater Geographic Information System) using AUV is also described.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

There are several challenges that need to be addressed before the technology gains full engineering and market confidence. One of the main technical hurdles is the need to address part-load problems of wave energy converters resulting from bathymetric conditions and variations in wave parameters such as wave frequency and height. As such, the wave phenomenon is inherently variable in time and space. This is compounded by the fact that wave energy conversion devices are less efficient at part-load. This paper discusses sources of part-loads in wave energy conversion including their impact on system efficiency for a California weather scenario, also relating wave energy conversion techniques to part-load efficiencies","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

Shinkai 6500 has a depth capability of 6500 m and was developed in 1989 by JAMSTEC, and Mitsubishi Heavy Industries, Ltd. (hereafter MHI). She was commissioned in 1990 with her exclusive support vessel \"YOKOSUKA\" (length overall; 105 m, gross tonnage; 4,436 GT). Shinkai 6500 has dived 811 times until the end of March 2004. The major dives were carried out in the East Pacific Raise, the Mid Atlantic Ridge, the Indian Ocean and the western Pacific region, including the Mariana Trench and the Japan Trench. She has achieved many fruitful and important scientific results for the science in the world. The original power source of Shinkai 6500 was oil filled pressure compensated silver oxide zinc battery. However, the silver-zinc battery is very expensive, has short life, and is necessary complex work for maintenance. The operators needed to do full electric discharge every 15th dive, and to adjust electrolysis liquid after 30 dives. In order to supply electricity for the Shinkai 6500, two 400Ah battery pods, 800Ah in total, are installed. From 1997, the JAMSTEC Shinkai 6500 operation team, and MHI and Japan Storage Battery Co. Ltd started to develop the 400Ah capacity oil filled pressure compensated lithium-ion battery for Shinkai 6500 main batteries. And we completed development and sea trial in March 2004. The advantage of lithium ion battery in comparison with silver zinc battery is (1) maintenance-free, it is not necessary to do adjustment of electrolysis liquid. (2) long life time, the battery life time increased from 75 times or 1 year, to 180 times or 2 years, and (3) light weight, it is about 100 kg lighter than the silver zinc battery system. We will development and result of operation of introduce the first big capacity oil filled pressure compensated lithium ion battery for the Shinkai 6500.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

The measuring points scanned angles of bending in the main bending planes are corrected due to transversal inclination of measuring points and vice versa. The paper considers the system for the measuring of inclination angles on the ship hull measuring points. The measuring points consist of three digital inclinometers operating together that measure inclination angles in longitudinal vertical plane (xz), plane parallel to longitudinal horizontal plane (xy) as well as in transversal vertical planes. The system consists of measuring points which are placed at the deck connection of transversal and longitudinal bulkheads or transversal bulkhead and sheer strake. The paper describes use of measured and calculated angles of inclinations. This paper is also the base upon which it is possible to organize the real system of ship hull deformations and motions monitoring in service and sailing conditions.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

The acoustic camera provides a sequence of 3D images in real time (about 5 fps in the current version). Data must be registered and fused to generate a unique 3D mosaic in the form of a triangle mesh, which is rendered through a graphical interface. Available technologies for registration and meshing have been modified to match time constraints.
