Eager.one has successfully completed the design and construction of 2 new transition piece (TP) lifting tools for the Jumbo Javelin. This is one of the Offshore Construction Vessels Jumbo deploys for its Offshore Wind projects. These new TP tools have a lifting capacity up to 750 t and are designed to be used for lifting...
Jack up leg and spudcan installation
Jack up vessel Aeolus
Aeolus (Van Oord) is an innovative and advanced transport and installation jack up vessel for installing Offshore wind turbines. The jack up vessel was ordered by Van Oord at the German shipyard Sietas in Hamburg and was to be delivered in September 2012. Eager.one was asked to construct leg-lifting equipment and to prepare a method statement for placing the legs and spudcans.
Install legs into jack up vessel
We designed heavy lifting equipment for lifting the four legs. We came up with the idea of a hydraulic pin-pusher lifting tool to lift the legs at the top. At the bottom of the leg we installed a tailing frame to support the legs during the upending. First we placed the legs upright on the dock and removed the frame before positioning the leg into the jack up vessel.
Spudcans attached by divers
As the four legs were installed, it was time to attach the spudcans to the legs. Spudcans are inverted cones which are mounted below the jack up legs. Eager.one prepared method statement to install the spudcans out of the drydock. Via the jack up leg a cable was lowered and attached to the spudcan by divers. The spudcan was then lifted and bolted to the leg from the inside. A very precise job.
To cover this operation our engineers were presented at the time the spudcans were installed. Setbacks could be helped immediately and on the spot, this ensured a swift operation.
