Shes also really quiet.
With the recent news of Cape Sharp Tidal’s troubles, it was interesting to see a report out of UK’s independent – about success in Scotland’s Tidal energy test site off Orkney. Orkney features a 4-5m tidal range, which equates to 12-15 feet, or around 1/3 of the Fundy Force test Sites Tidal Range.
The Scotrenewables Tidal Power SR2000 turbine, produced 3GWh in its first full year in operation, including over the winter. the turbine is designed to float on the surface, and moored in place, with an inverted windmill like structure to generate power.
to my eye – this looks like a relatively simple system to deploy and maintain. also Good news for Fundy Force – DP Energy Canada plans to test one of these devices here in the future, and may prove to be the Redeemer of tidal energy in Nova Scotia after the failure of OpenHydro, and the Cape Sharp Tidal Partnership.
The Cape Sharp turbine, currently installed in the Bay of Fundy by the troubled Open Hydro is a large Doughnut shaped structure, with blades on the inside is designed to sit anchored to the ocean floor.
this appears to be a much more complex system, as the required sub sea infrastructure is significant, and all construction and maintenance activities require specialized barges, powerful tugs and divers.
3 other Projects are also in the works.
DP Canada also plans to test a Anchored Monopole turbine – think of it as a wind turbine, but mounted on the sea floor. this option will likely run into the problems of the Open Hydro turbine, but the advantage to mounted turbines on the sea floor is that they are invisible on the surface, and potentially less problematic for surface traffic.
Minas Tidal is looking to deploy Tocardo generators on a semi-submersable frame, moored to the seafloor. (above) This project is very similar to what was done in Scotland – the turbine is in commercial use already, Each unit is rated at 250MW – the trick for them will be to find a configuration and logistical solution that works. the example above, deployment is accomplished by floating the entire assembly horizontally, then submerging it into the proper orientation.
Sustainable Marine Energy or SME, is preparing a test turbine for installation in DIgby Neck. they also had a turbine installed at the Scottish test site. Black Rock Tidal is owned by the turbine maker, and is looking to commercialize this technology in Canada. SME’s project will deploy a PLAT-I tidal energy platform hosting four SCHOTTEL HYDRO SIT 250 turbines. this turbine is a moored floating structure, with the turbines placed in the water below.
the ultimate installation is project to look like the image below. Of note, the Plat-I test platform arrived on the Atlantic Sky, on July 4.
With Monday being Labour Day, the port is basically closed. the Cruise Ship Veendam is the only scheduled caller today. Several vessels were able to work on Saturday and Sunday
CMA CGM Loire, and Arica made stops at Halterm on Saturday. Loire operates on CMA-CGM’s Columbus Loop Service. Arica, also a CMA-CGM vessel is running on the Maersk SL1 service.
Sunday saw MOL Paramount, YM Express and Breivik Bridge Call at Fairview Cove.
(Above) COSCO shipping bulk carrier Tao Hua Hai took bunkers at anchorage 1, then sailed for Corpus Christi Texas with a load of Iron Ore from Sept-IIes Quebec.
Post media is reporting that the Federal Government is expecting the first AOPS to be delivered the First week of October. this is a feat, as its only expected to be launched in September.
Curiously, Last week the Halifax Examiner quoted Sean Lewis, Communications director for Irving Shipbuilding
We are on schedule to launch the first Arctic and Offshore Patrol Ship (AOPS), the future HMCS Harry DeWolf, late September 2018. Harbour acceptance tests and trials have started and will continue, along with further outfitting, over the next several months. The first AOPS is scheduled to be delivered to the Royal Canadian Navy in summer 2019.
As of yesterday, the Hull was still tarped off for final painting
CBC News is reporting that an oil slick was spotted off bishops landing Monday morning. The coast guard is reporting the source of the slick is currently unknown.
Additionally, a local Mariner has reported that the Coast guard itself reported an Oil Slick stretching from BIO to Tufts Cove.
From the photos posted by CBC, Bishops slick has the distinct rainbow pattern, as one would see with Spilled Gas. As I under stand it, Bunker C, like what was spilled at tufts cove is thick, and floats in clumps.
This Post will be Updated at https://blog.halifaxshippingnews.ca/2018/08/more-oil-in-the-harbour.html as more is known.
DND issued a tender to dispose of, through Ship Breaking, three auxiliary vessels YDG-2 a Deperming Barge, YRG-60 a Fueling Barge and YDT 12 Granby, which serves as Diving Tender with the Fleet Diving Unit. The winning bidder will have 45 days to remove the vessels from the Dockyard, and 1 year to complete disposal.
YDG 2 – is a Deperming Barge used for Degausing ships. YRG 60 is a Fueling Barge – used to bunker vessels within the dockyard. Granby includes significant diving facilities, including decompression chamber, so while old, its disposal is a bit surprising (the larger CFAV SECHELT YDT-610 is still in service)
Recently I tweeted a map of 1 month of Halifax traffic from November 2011, and commented its due for an update. The latest data i have is from August 2016, so i Set out to Make the updated map. While Doing it, I also decided to Document how i did it.
the first thing to do is grab the Log files from ShipPlotter. in my case the default location of C:\COAA\Shipplotter\logs was used. Below is a small Excerpt from one of the Logs. A Days data is about 15mb of Raw txt.

I choose the month of august, as it was the most recent full month i had. in the folder with all the .log files, run a simple copy command to combine them all into one big file. Due to the Size, I combined 6 days of data into one file.
Copy *.log bigfile.txt
once combined, i use excel to grab the entries with a navigation status of “Under Way” I considered also collecting moored vessels, however just the underway vessels produced over 4 million lines of data in total. Once the csv file is open in Excel, I text to columned it, splitting on the semi colon. I then sort by by the Navigation status, and deleted all rows above and Below under way.
then i removed the excess columns, and saved back the csv.
after doing this with all 6 files, i combined them into one.
I then used notepad ++ to do a sanity check on my data – remove weirdness, and clean up the excess trialing comas. Once the underway data is collected, I combined the 5 files, and then added a Header row, to identify the MSMI, Lat, Long and the date. I am making this data available, and you can download it here: http://halifaxshippingnews.ca/AugPoints.csv (.csv 115mb) the data includes Lat/Long, Date/time and ships MMSI.
Once we have the points file, then we can move on to mapping it. – which didn’t work. oops. Need to get rid of the N, and W directional, and update to -63 to specify a west direction.
For this map, I grabbed QGIS – which is free, and created a layer from the XY Data. You basically get a Point Cloud.
The final Map used watercourse data from GeoNova,then the image was exported from QGIS. I then manually cleaned it up in Photoshop, removing the excess watercourses leaving only the shoreline. this is also where the labels and title block were added.
I should note the 2011 map was made in ArcMap. ESRI has made getting trial licenses a pain (And i have run out of email addresses) hence me turning to QGIS.
SO the Dockyard. In the foreground HMCS Toronto. Behind her is HMCS Montreal undergoing a work period. Tied up 2 abreast, HMCS St Johns and HMCS Halifax
the Bridge is a great spot for photos – As seen below.
If you have 15 minutes, give a listen to the latest episode of the Podcast 99Percent Invisible. It Talks about BBC Radio’s Shipping Forecast, and how its become a cultural phenomena in Britain. The Podcast discusses the origins of Marine weather forecasting, and the efforts made by Admiral Robert FitzRoy, who commanded HMS Beagle on Darwin’s trip to the Galapagos, to predict the weather.
On Thursday, a Duck Boat, capsized and sank on a lake in Branson Missouri. 17 are dead, and of the 12 people who survived, 7 are in serious or critical condition. Questions are being asked about the safety of these craft, and given Murphy’s Ambassatours operates several, its worth a look. There have been several incidents involving amphibious vehicles in the last 20 years – in 1999, another DUKW sunk in Arkansas, killing 13. Closer to Home, the Lady Duck Sunk in the Ottawa River, killing 4 in 2002.
The DUKWs involved in the Arkansas and Branson Incidents are actually a modern replica of a World War II design. Ottawa’s Lady Duck was a modified Ford Pickup. Halifax’s Harbour hoppers are military surplus Vietnam Era LARC’s, so there are significant differences in terms of the vehicles involved, however a review of the Investigation reports into these incidents reveals similarities.
A Transportation Safety Board report into the sinking of the Lady Duck revealed that the vehicle was registered as a motor vehicle only, and not as a small vessel, thus it fell into a regulatory vacuum, and was not in compliance with marine regulations. Additionally, Small vessel regulations were very different in 2002 then they are today. Harbour Hoppers are regulated as Both a Bus (by the province), and as a Vessel (by Transport Canada) and are registered as vessels.
The TSB Report into the 2002 sinking of the Lady Duck, echoed some of the recommendations from the NTSB’s report into the Arkansas sinking, and actually included a portion of the report as an appendix. Specifically both the TSB and the NTSB recommended requiring the vessels posses enough reserve buoyancy to stay upright and afloat when flooded, and to remove canopies, or use canopies that will not restrict horizontal or vertical escape by passengers. Additionally, both reports cited a lack of maintenance to the vehicles, specifically surrounding pumps required to remove water from the vessel.
The main cause of death in both the Arkansas and Lady Duck incidents was people getting trapped by the canopy, and being unable to escape. Photos of the Stricken Duck boat from Branson seem to show that the passenger area was fully enclosed on top and on the sides. the Harbour Hoppers use a awning, which is open on the sides. as well as they are registered vessels they must meet construction and stability regulations.
I have also been informed that the Hoppers are pulled from the water the moment the wind gusts reach 22 knots / 41 km/hr. That’s a hard cutoff that both the company and Halifax Traffic (the MCTS center that controls ship traffic in the harbour) enforce strictly.
The Hoppers are also required by Transport Canada to stay within 150 meters from shore. This is mostly to keep them out of the way of the larger commercial traffic, but it doubles as a safety net where the Hoppers are never more than 30 seconds from a floating dock.
Witness reports indicate that waves on the lake in Branson were hitting 6′ in height at the time of the incident, due to a fast approaching thunderstorm. Ultimately the report into this incident will likely sight Weather and the decision to sail, the enclosed canopy, and a failure of regulators to implement recommendations from the 1999 Arkansas incident as the causes.
