Hi

Are you going to keep all the buoys providing turbidity and water temperature information after the dredge has gone? Ie are these buoys and their real time info permanent

Thanks

Hi Rayner,

As we still have some minor dredging work for the reclamation and cruise berth, the buoys will stay for another 6-10 months. So you will be able to keep an eye on the water quality and temperature for a while yet.

What is going on just beyond Rapapa Island -towards the Heads- some sort of piling??? for what?? A barge and crane putting down pile/s
Thanks

Hi Terry,

The barge and crane are starting to put in new navigation aids for the deeper, wider and longer shipping channel. Keep an eye out for an upcoming blog story on what they are and how they work.

What sort of fuel does the dredge use that it has to go to Wellington to get it?

Hi Ray,

The Fairway can use a range of marine fuel oil, unfortunately there isn't sufficient volumes of those fuel available in Lyttelton. So she had to whip up to Wellington for refuelling.

Hi, What's the small boat called " Capricorn Alpha"
doing ? Cheers Bruce

Hi Bruce,

The Capricorn Alpha is a 'sweep tug' which is working on the Channel Deepening Project. She tows a large blade along the sea floor to even out the troughs and humps left by the bigger dredge. She also helps scrape off the shallower parts that the big dredge cannot reach.

Fairway dredge is on route to wellington tonight, any reason why.

Hi Neville,

Good spotting! Yes, she is off to Wellington to refuel as there is not enough fuel available in Lyttelton. She will be back on Thursday.
