As one of the counterplans to the global warming problem, wind power energy has promising availability in natural energy, and the technical development of wind energy conversion systems is also tackled in Japan. Since the sea has less restriction about social conditions than land, paying attention to the geographical conditions of the Japanese country surrounded by the sea our own time demands, basic investigation about offshore wind energy conversion systems. This paper presents an example of examination for the Miyake island circumference ocean space with emphasis on "wind power investigation", using the prediction program WAsP as wind climate prediction in offshore windmill installations site. The amount of power generation is estimated with regard to some concrete windmills, and then, as one concept in a system design, an energy conversion system (called "offshore wind energy conversion fleet network system") with the windmill of a float type is proposed. It is confirmed that industrialization of offshore wind power is a theme of an energy policy of Japan which deserves examination as a proposal on the other hand.

Ocean storage of the captured CO_2 from fossil-fuel burning is a possible option for mitigating the increase of CO_2 concentration in the atmosphere. Moving-ship type of CO_2 ocean storage is a concept whereby captured and liquefied CO_2 is delivered by ship to a site and injected into the deep ocean by means of a pipe suspended beneath a ship as it slowly moves through the water. In case of bad weather conditions, CO_2 marine transport and operation on the sea should be adjourned although CO_2 would be captured at the plant every day. It is, therefore, required that the system would have the buffer storage at the port and the extra shipping ability to recover the delay of schedule. Since the large scale of such spare capability might lead to the increase in cost, it is needed to investigate how to plan the system allowed for weather conditions reasonably. In this study, a time series model of sea state through one year is generated for a hypothetical ocean storage site, based on the wind data observed with satellite remote sensing, and simulations of CO_2 marine transport and operation on the sea are carried out considering the operational limit of sea state. In this approach, the continuing bad weather days or the frequent occurrences of rough sea condition during the specific season are counted automatically. In order to pursue higher efficiency of the operation, side-by-side type and tandem type of moorings are applied for the simulations and compared. Finally, cost assessments under the several assumptions are carried out to see the relative merits among that the number of ships would be increased, that the loading capacity of a ship would be increased, and that the storage capacity at the port would grow, which are generally in trade-off relationships.

It is of importance to evaluate the ship manoeuvring motion, such as the berthing in a harbour, the drifting behaviour of a disabled ship. A significant part of the lateral hydrodynamic forces acting on a ship will be due to cross flow drag, as the ship's drift velocity becomes relatively larger compared to the ahead speed. For the prediction of ship manoeuvrability at larger drifting angles, it will be required to estimate the cross flow forces accurately. In this paper, a calculation is given to the longitudinal distribution of the cross flow drag coefficient over the length of ship moving transversely. The theoretical method on basis of vortex model developed by the authors is applied to the Wigley hull and a container ship hull. By comparing with the measured results of captive model tests, the prediction results agree well with model tests. Therefore, this method will be useful for practical prediction of cross flow forces acting on a ship moving laterally, taking into account the forms of the ship's cross sections.
