Wind and stuff

A collection of pictures taken during the Thanet and London Array construction campaigns plus a bit of oil and gas for good measure.

Thanet SS aboard transport barge at Lowestoft. A very nice shade of orange I thought.

Thanet SS in all its construction yard glory. SLP at Lowestoft. One of the few places in the UK to make Peterhead look sophisticated.

Vestas nacelle on the quay at Dunkirk, more pleasing lines than the Siemens units, less reliable though, some say.

Vestas WTG base units on the quay at Dunkirk. If memory serves me right, nine WTGs could be loaded onto the installation vessel in 24 hours provided that wind conditions were benign. A WTG could be installed to the foundation and fully assembled in around 12 hours if weather conditions behaved themselves. Each installed WTG at Thanet worked out at around £10.000,000 The equivalent WTG ashore would cost 20% of that.

Trailered loadout Ravenna. Being Italy the loadout contractor wants to remove his trailers immediately the load is in place and set down on the grillage. Invariably they are booked to another job and are wasted 'soonest'. This requirment at odds wuith then need to weld the 'load' to the grillage which can take days. Always a bun fight, always fraught, always a compromise. Never easy. The lot of the MWS not a happy one.

Always a bun fight, always fraught, always a compromise. Never easy. The lot of the MWS, in Italy,  not a happy one. A nation of anarchists, albeit well dressed anarchists.

 

A couple of 'muthafukka' ocean tugs but built in the AHT style. Traditional ocean going tugs tend to have more graceful lines and bigger fuel capacites than AHTs but are less manoeuvrable in station keeping mode and can not be used for most deep-water mooring work. These two were part of the three tug spread used to tow FPSO Plutonio from Ulsan Korea to offshore Angola.

MAting the upper grillage to the lower grillage can be fraught with compromise if the dimensional control boys have been a bit lax, usually the case in Italy. Here. In a perfect world everything is within 5 mm of where it should be.
