Netting has been put in place at the end of the cruise berth site to ensure seabirds don’t get too close to the construction works.
Following advice from wildlife experts, we have installed fences and netting to discourage the birds from nesting there, as construction in this area will shortly get underway.
We’ve kept watch on the birds, and can see they’ve moved to the adjacent Z-Berth wharf - a much safer area.
The Fairway had a successful trip to Wellington, her fuel tanks are now full and she commenced dredging again this morning.
After two weeks of dredging, the Fairway needs to top up her fuel tanks. That requires a trip up to Wellington, so she'll be away for a few days (it takes a long time to fill her tanks!). We hope to see the Fairway back on Wednesday evening or Thursday morning.
Last week the Fairway had a visit from Environment Canterbury (ECan) staff so they could have a look at how the dredge works – inside and out!
ECan compliance officers, customer service staff and a marine scientist made the visit to ensure we were complying with the conditions of our dredging consent. By coming on board and getting first-hand information the ECan staff now better understand how the dredge works and can confidently answer any of the public's questions.
Before getting on board, they went through a safety briefing on shore. It was a picture-perfect day on the water, so everyone enjoyed heading out on the survey vessel to get to the Fairway.
ECan staff had plenty of questions about the dredge, and one of their top priorities was to hear how we are keeping an active lookout for marine mammals and how we record any sightings. All of the Fairway bridge crew have been trained in marine mammal observation and they keenly record any sightings made to help us better understand marine mammal behaviour around dredgers.
As part of our effort to understand the way our projects alter the underwater noise environment, we’ve spent some time on the water measuring noise from the dredging and cruise berth piling projects.
Last Thursday, we joined an acoustician from Styles Group, and an environmental engineer from Boskalis, as we headed out on a survey boat to record noise with four hydrophones, which work like underwater microphones.
We set up the hydrophones at various distances from the dredge, and recorded the sound as the dredge moved along the Harbour, passing the hydrophones. This was done a few times to ensure we had collected the best data possible.
A single hydrophone was also installed about 20-25m off the cruise berth piling to measure the amount of noise the on-land piling may be causing in the water.
The data is now being analysed by Styles Group, and will help us better manage potential effects on Hector’s dolphins in the Harbour.
We understand the Fairway is louder than most vessels tied up in the Port, and that it has been heard by several residents in Lyttelton overnight.
The Fairway emits quite a distinctive low frequency noise. We apologise for any inconvenience this noise has given residents, and we have spoken with the Captain and Chief Engineer to look at ways to reduce the noise tonight. The Fairway is running on the minimum possible power, but unfortunately the noise has not reduced significantly.
Tuesday night (August 28) will be the last night the Fairway is in Port, as she will start dredging at first light on Wednesday. Again, we apologise for any disruption this has caused and appreciate your patience.
If you have any questions or concerns please contact LPC Environmental Adviser Jared Pettersson on 021 679 838, or email firstname.lastname@example.org.
The Fairway has made the journey to Lyttelton, and arrived in Port around 9am Monday morning. She was an impressive sight emerging from the fog bank just off the heads!
The Fairway will be docked in the Port for the next two days as the crew undergoes custom clearances and inductions.
She will start dredging at first light on Wednesday, and will work 24/7 to deepen, lengthen and widen the channel, as part of stage one of the channel deepening project.
Fairway Captain Marco de Bruin has spent 29 years working with Boskalis, and is leading a crew of 35 for the next 12 weeks as the dredge gets to work.
The Fairway crew sent some great shots of the Pilot coming aboard to transit through Torres Strait. Looks nice and calm out there!
