As offshore windfarms move into deeper waters, there has been an increasing need for jacket foundations. A pre-piling template simplifies the construction process as it enables piles to be driven into the seabed in advance, quickening the commencement of accurate offshore piling operations.
The diverse range of offshore expertise across ALE’s branches, including their Conbit operation, enabled them to provide a full pre-piling template installation package that was smoothly co-ordinated. ALE’s experience and flexibility also ensured they could work around the client’s schedule.
ALE’s scope consisted of a barge load-out, transportation and installation of the pre-piling template. The project began in Rotterdam, the Netherlands, with an SPMT load-out. The pre-piling template was set down on supports and the SPMTs were then removed from the barge.
When the barge arrived at Invergordon, Scotland, the pre-piling template was transferred to a jack-up vessel for installation offshore. SPMTs were prepared beneath the centre of the pre-piling template with an additional stability bracket. ALE opened the clamps around the jack-up vessel’s legs to enable the template to be manoeuvred.
