UPWIND WP4: Offshore Support Structures and Foundations<br />
Applicability <strong>for</strong> FOWT:<br />
• Detailed requirements <strong>for</strong> <strong>design</strong> calculations. Description <strong>of</strong> load cases which cover <strong>design</strong> situations<br />
and external conditions. Applicable <strong>for</strong> FOWT too. Extension to further specific requirements <strong>for</strong> FOWT<br />
is needed.<br />
• Restrictions: specific requirements <strong>for</strong> FOWT (e.g. floating units, mooring) mainly as reference to Offshore<br />
Rules.<br />
BV Guidance Note NI 572 DT R400 E, November 2010 – Classification and Certification <strong>of</strong> Floating Offshore<br />
Wind Turbines<br />
Scope:<br />
• This guidance notes gives requirements and recommendations <strong>for</strong> the classification <strong>of</strong> Floating Offshore<br />
Wind Turbines.<br />
Applicability <strong>for</strong> FOWT:<br />
• The load cases adopted <strong>for</strong> the <strong>design</strong> are defined on basis <strong>of</strong> the minimum load cases required by<br />
IEC 61400-3 or load combinations <strong>of</strong> Offshore Rules.<br />
ISO 19904-1 - Petroleum and natural gas industries - Floating <strong>of</strong>fshore structures - Part 1: Monohulls, semi<br />
submersibles and spars<br />
Scope:<br />
• Requirements and guidance <strong>for</strong> the structural <strong>design</strong> and/or assessment <strong>of</strong> floating <strong>of</strong>fshore plat<strong>for</strong>ms<br />
used by the petroleum and natural gas industries. Reference to DNV-OS-C101.<br />
Applicability <strong>for</strong> FOWT:<br />
• General requirements <strong>for</strong> floating <strong>of</strong>fshore plat<strong>for</strong>ms<br />
• Restrictions: No specific wind turbine <strong>design</strong> load case requirements<br />
ISO 19901-7 – Petroleum and natural gas Industries – Specific requirements <strong>for</strong> <strong>of</strong>fshore structures – Part 7:<br />
Stationkeeping systems <strong>for</strong> floating <strong>of</strong>fshore structures and mobile <strong>of</strong>fshore units, 2005<br />
Scope:<br />
• This part <strong>of</strong> ISO 19901 specifies methodologies <strong>for</strong> the <strong>design</strong>, analysis and evaluation <strong>of</strong> stationkeeping<br />
<strong>for</strong> floating structures used by the oil & gas industries<br />
Applicability <strong>for</strong> FOWT:<br />
• General requirements <strong>for</strong> floating <strong>of</strong>fshore structures<br />
• Restrictions: No specific wind turbines <strong>design</strong> load case requirements<br />
DNV-OS-C101 - Design <strong>of</strong> Offshore Steel Structures, General (LRFD method)<br />
Scope:<br />
• Provides <strong>design</strong> principles, technical requirements and guidance <strong>for</strong> the structural <strong>design</strong> <strong>of</strong> <strong>of</strong>fshore<br />
structures. DNV-OS-C101 is the general part <strong>of</strong> the DNV <strong>of</strong>fshore rules <strong>for</strong> structures.<br />
Applicability <strong>for</strong> FOWT:<br />
• General requirements <strong>for</strong> all <strong>of</strong>fshore structures<br />
• Restrictions: No specific wind turbine <strong>design</strong> load case requirements<br />
