Conceptual Design of an Ocean Nutrient Enhancer for Development of Fisheries

摘要

The conceptual design of an Ocean Nutrient Enhancer (ONE) is described, which will be used for enriching new fisheries with nutrients. The design intends to identify the concept of deep ocean water upwelling structure based on feasibility studies of a structure that is composed of a submerged vessel equipped with power supply, pumps and a riser for deep ocean water, and the system is moored on seabed. The design of the system is evaluated from extensive aspects such as engineering reliability, operational and economical viewpoints.
