offshore wind potential new i nstallations
Offshore Wind Potential – New Installations
  • The European Wind Energy Association (EWEA) increased its 2020 target to 230 GW wind power capacity
    • Including 40 GW offshore wind (March, 2009)
  • To reach 40 GW of offshore wind capacity in the EU by 2020
  • Average growth in annual installations of 28% - from 1 GW in 2011 to 6.9 GW in 2020.
  • Assumption - 1 vessel installs 100 turbines per year, each turbine = 4 MW

+ maintenance and repair

20-25 vessels needed in Europe

Ship-shaped self-elevating wind turbine installation vessels

Class assumptions:

Mix of offshore jack-ups and cargo ships

Design assumptions

Vessels carry out repeated operations in restricted waters

Limited design conditions

Relevant design loads for all design/operational conditions

Ability to escape/ leave the field in case of bad weather.

Jacking System

Extended fatigue requirements to the jacking system because of many load cycles. (One jacking system operation every second day)

Design and construction of jacking system ensure the possibility for the vessel to go into a floating condition and escape from site.

dnv new jack up rules
DNV New Jack-up Rules

Clear guidance is especially important in the self-elevating market

The Jack-Up market deserves its own considerations

DNV have taken our accumulated knowledge and experience

Beyond class rule requirements – zero down time during operations

dnv classification rules for self elevating units
VersionDNV Classification rules for Self-elevating units

DNV research projects

  • Full-scale measurements of structural response due to wave and winds at Ekofisk in November 1977
  • Joint industry project in 1980–83 with several participants
  • Made it possible for DNV to develop the FIRST classification rules for jack-up rigs, accounting for dynamic amplification of structural response in deep water and harsh environments.

DNV committed to self-elevating units

  • Focus with:
  • Dedicated rules guiding you through
  • A jack-up service centre in Dubai
  • Experts devoted to the segment

We know:

the difference between good and poor design solutions.

the specific JU-interpretations of rules and regulations.

to recognize simple efficient solutions

how to help you out in case of problems

We understand:

the needs of the self-elevating market.

the specific design solutions

the need for on time deliveries
