Brief introduction to SOA and NOTC


IEA | OES

Introduction to SOA

• The main functions of State Oceanic Administration (SOA)is to take the implementation of maritime legislationis to take the implementation of maritime legislation,planning and management, is responsible for overallcoordination of ocean affairs.

• In 2008，the State Council mandated the responsibilities——“Research, Application and Management of Marine Energy” to SOAManagement of Marine Energy to SOA.

• The Main tasks of SOA:• Survey of marine energy resources• Survey of marine energy resources• Formulation of the policies and

standards for marine energy• Organization of technology Research• Organization of technology Research,

Development and Demonstration for marine energy.


IEA | OES

Introduction to NOTC

• NOTC is under the leadership of SOA. The main duties of NOTC are to take management for ocean technology (including ocean energy), and provide technical support for national ocean operational systemfor national ocean operational system.

• NOTC is the earliest institute in China which engages in i h d d l tmarine energy research and development.

• NOTC has established a professional• NOTC has established a professional marine energy laboratory and a branch of the Commission of China Ocean Standard for making marine energy standards.


IEA | OES


Since 1985, NOTC has completed Xiaoheishan wind desalinationproject Xiaomai island "8 kW Pendulum type Wave Test Powerproject, Xiaomai island 8 kW Pendulum-type Wave Test Power Plant“ project and Daguan Island "30 kW Pendulum-type Wave Power Plant Demonstration” projects.

The main tasks of NOTC for ocean energygy• Undertake the survey and assessment of marine energy

resources of China• Draft the policies and strategies for marine energy• Draft the standards of marine energy• Take charge of building and operating of ocean energy sea

test site• Engage in technology research and development of

marine energy, especially focusing on wave energy iconversion.

Ocean energy policy in China


IEA | OES

Law and special plan

• The Renewable Energy Law, revised amendment in Dec. 2009 has raised a special grant for renewable energy2009, has raised a special grant for renewable energy, including marine energy.

• SOA will draw up the ocean energy development special p gy p pplan, and incentive policy for promoting the utilization of marine energy.


IEA | OES

Relative Plans

• A lot of national plans and strategies including the tasks p g gin development and utilization of marine energy:

• Mid-Long term Development Plan for Renewable Energy• National Program for Mid-Long Term S&T Development

(2006-2020) • National marine development

plan (2006-2010)• National program to boost

marine industry through S&T advances (2008-2015)


IEA | OES

Supportive programs

• Key Technologies R&D Program MOST - ¥60M for OES• Key Technologies R&D Program, MOST - ¥60M for OES• High-tech R&D Program (863 Program), MOST - ¥10M..• Ocean Public Benefit Research Project SOA ¥10M• Ocean Public Benefit Research Project, SOA - ¥10M..• Ocean survey and evaluation project, SOA - ¥ 24M..• Knowledge Innovation Program CAS ¥ 5M• Knowledge Innovation Program, CAS - ¥ 5M..

In addition SOA is actively working to establish aIn addition，SOA is actively working to establish a special fund for the development of marine energy.
