Classification society Germanischer Lloyd in Germany has now published its Regulation for the Certification of Offshore Wind Energy Conversion Systems. The hardback document contains 13 chapters, of which chapter five through ten contain new information for the wind community. The remaining chapters are also found in Germanischer Lloyd's Rules and Regulations for the Certification of Wind Energy Conversion Systems, published in 1993. Chapter 4, however, now includes sea currents, sea waves, sea level, sea ice and sea bed, under the section on external conditions. The new chapters are drawn from the society's Rules for Offshore Installations.
