SPONSORS OF THE CONCRETE FOUNDATION FEATURE CONCRETE MARINE SOLUTIONS


DTI 50 The DTI 50 is the only design which attempts to provide a solution to the problems of constructing offshore wind farms, from the building of port infrastructure to final decommissioning; only by adopting a completely integrated solution can we hope to achieve the savings which will allow the industry to progress with confidence.


DTI 50 SPECIFICS • Designed specifically to minimise the construction of additional port infrastructure


• Building, delivering and installing complete units, without any heavy lifting on site


• The foundation is designed to accept the turbine tower within the main support column, reducing the overall height and allowing the nacelle and blades to be fitted, and systems tested at the quayside.


• The foundation is designed to be self levelling, with systems built into the base to permit installation with minimal sea bed preparation.


• The system requires no mooring or positioning anchor spread


• On site, by flooding the main support column, the turbine tower can be raised to its working height and secured, with no heavy lifting required


• The main support column is designed with 4 sets of projecting buttresses. Each pair houses a recessed access ladder and remotely controlled lift


• Substantial additional ballast can be easily “rainbowed” by the dredger and contained within the boundary walls.


• By relocating the installation pontoon and raising it to the height of the main support column it becomes a working platform


• By reversing the installation procedure the foundation can be removed/ relocated/or recycled for other marine related projects


• The basic foundation can be used as a distribution hub or fitted with accommodation modules


DELIVERY AND INSTALLATION PONTOON


The primary function of the installation pontoon is to provide the stability and the lifting capacity to deliver complete units from construction yard to site. As the unit leaves the yard and as the water depths increase, the lifting / jacking legs gradually lower the foundation, improving stability and reducing motion from weather conditions.


On site, the pontoons built-in propulsion systems will position the foundation accurately and level the seabed prior to final touchdown.


This approach to delivery and installation has many advantages, too many to list in this introductory article.
