and larger turbines, jackets are more competitive; • In China labour cost is lower - steel cost similar - jackets will in general be more competitive.
• 2015: • Water depths up to 60 m; • Typical turbines size for planned projects: 7 MW; • Dominating: Monopiles and jackets.
Jackets introduced for offshore wind in 2002 – first pilot in 2006

• Introduced jackets for offshore wind in 2002 – first project 2006;
• Work for Ming Yang since 2013. • Richard Zhu is my best partner to
introduce jacket to china offshore wind.
Short about myself and my partner
• Background from:
• Offshore R&D; • Certification of offshore structures (DNV); • Design of foundations for oil and gas (steel, gravity) – (Ref: Troll, Ekofisk).
Patented system for preinstalled piles (not shown)
Summary of offshore wind since 2001
• 2001 – beginning commercial projects: • Shallow water ((5-10 m); • Small turbines (2 MW); • Dominating: Monopiles /gravity foundations.

Beatrice 2006 – new records: •Water Depth: 50 m - (also adapted in 12 m); •Turbine size: 5 MW.
Jacket – where are they suitable?
• Jackets lighter than monopiles; • For larger water depths, difficult soil
