The year 2011 offshore wind power market was :
• 235 new offshore wind turbines, in nine wind farms, worth some €2.4
billion, were fully grid connected between 1 January and 31 December 2011, totalling 866 MW, 17 MW less than 2010.
• 246 turbines were erected during 2011, an average of 2.6 MW per day. 81 of these turbines are awaiting grid connection.
• Three experimental foating concepts were erected, one of which was a fullscale grid connected concept.
• Offshore work began on a further fve projects and preparatory onshore work on nine new projects.
Market outlook :
• Once completed, the nine offshore projects currently under construction will increase installed capacity by a further 2,375 MW, bringing cumulative capacity in Europe to 6,188 MW.
• Preparatory work has started on nine other projects, these have a cumulative installed capacity of 2,910 MW.
Trends: Turbines, foundations, water depth and distance to shore :
• The average offshore wind farm size in 2011 was almost 200MW up 29% (45MW) on the previous year.
• Average water depth in 2011 reached 22.8m, substantially more than 2010.
• Average distance to shore decreased, being 23.4km in 2011 compared to 27.1km the previous year.
Mr Keesjan Cordia, CEO of Seafox said, "The fact that Seafox 5 has already received a charter for immediate work speaks of the strength of the MPSEP design, the reputation of Keppel-made products and Seafox's track record in multi-support service jackups across the world.
"We see that demand for such vessels will continue to rise with the commercialisation of 5MW wind turbines over the next few years. Seafox 5 is a new generation vessel which will be able to out-perform existing marine assets both on cost and efficiency in wind installation. In addition, this state-of-the-art vessel has been specifically designed to meet all the requirements of both the offshore wind and the oil & gas industries in harsh environments."
Measuring 50m wide and 151m end-to-end, Seafox 5 will be among a handful of purpose-built jackups with a 1200-tonne heavy lift capacity and capable of installing both turbines and large foundations exceeding 800 tonnes in weight.
Together with its environmental capabilities, stability coverage, deck space of 3,600m2 and a variable load of 7,000 MT, it is able to outperform most other jackups and be competitive with the floating heavy lift vessels.

|Seafox 5 designed by KeppelFels OTD|
Designed by Keppel's research and development arm, Offshore Technology Development (OTD), Seafox 5 is a self-propelled installation jackup vessel utilising Keppel FELS' proven jacking technology. Equipped with Dynamic Positioning 2 (DP-2) capabilities, the vessel is elevated above sea level by four legs which provide 30m of clearance between the legs & crane for easy cargo access.
Seafox 5 has a large carrying capacity of up to 12 x 3.6MW turbines, three jackets or four tripods at a time, which enhances the efficiency of constructing offshore wind farms.
In addition to being well-suited for servicing offshore wind farms, it also meets the stringent operating regulations of the offshore oil and gas industry and can support a wide range of related activities such as accommodation, hook-up, commissioning, well intervention, maintenance, construction and decommissioning.
Accommodates bigger crew 150 people
