  Re: 1200T Self-elevating and Self-propelled Offshore wind turbine Service Unit
Dear Sir/Madam,

I have a keen client looking to purchase a Jack-up/Self Elevating Unit such as this "1200T Self-elevating and Self-propelled Offshore wind turbine Service Unit (DP-2)" that you have here on your website.

Of particular interest would be a unit with minimum 2000m2 Deck Area, 600-1000T Crane. Please could you kindly provide me with a brochure of any unit you have of such specifications?

Thank you and I look forward to hearing from you.

Best regards,
