Busy traffic at the Duluth piers today

20100909_4161
20100909_4214I took the picture of the traffic between the Duluth piers this afternoon (September 9, 2010. The Marine Tech dredge has been around the piers for several weeks now, clearing out the channel, particularly at the edges where silt and sand have a tendency to collect. Their tug Callie M., at the far left exchanges 2 different scows; she brings an empty one out and trades for the one just filled and takes it back to Erie Pier. She then repeats the process, again and again. Click here to listen to their whistle as they depart under the Lift Bridge on Tuesday, October 11, 2011. At right, the Canadian flagged Kaministiqua is departing Duluth between the piers with a cargo of grain. In the middle are two salt water ships at anchor waiting to come into port. The Beluga Fairy, built in 2009 and  making her first trip to the Twin Ports, is sitting just behind the Isa, a Polish ship that has been coming to Duluth on a regular basis since she was built in 1999. Unseen in the picture at top but seen at the left and also at anchor, is the Africaborg, built in 2007 and making her first trip here.

Drummond Islander II

The Drummond Islander III took over the car ferry duties of the Drummond Islander II in Lake Huron. MCM Marine, in Sault Ste. Marie, Michigan bought the ferry and uses it as a tug on dredge projects. It arrived in the Twin Ports on August 28th, bringing a barge and a work tug and a lot of pipe it is using to create a suction dredge for a project here. Above, it is tied up at the Meehan dock in Superior, where the John Sherwin used to be and the retired cement boat, J. B. Ford, built in 1904, is now. Photo taken on September 12, 2008

Dredging continues

The Marine Tech crane barge Dean R. Smith has been dredging in and near the shipping lanes in the harbor since the spring. Lately, it has been stationed close by the Lift Bridge. On Monday afternoon, it was working hard dropping the clam shell down to the bottom (about 29 feet below) and lifting material up and into the scow that was tied to the crane barge (above). They work with 2 scows; filling one with material from the bottom, mostly sand, while the other is taken by the tug Callie M. to Erie Pier on the St. Louis River where it is emptied. They then return to the crane barge and exchange scows. Photo taken on August 19, 2008

Dredging the harbor is a no-win battle

dredge2008Aug14_9959
We haven’t had a lot of ship traffic coming under the bridge for a few days. No salties have been here for over a week, and a long line of boats over the weekend means they are now out dropping off their cargo before coming back here for more. Yesterday, we had two boats arrive in the early morning and leave late in the day, working just like the rest of us. Today, the James R. Barker and the Indiana Harbor will both arrive for work in the morning and leave later in the day. One thing doesn’t change. The Marine Tech crane barge has been lifting silt and sand off the harbor bottom close by the Lift Bridge. Lacking boat traffic, people have been watching the crane on the barge dredge the bottom of the harbor one clam shell scoop at a time. Photo taken on August 14, 2008

Canadian Olympic meets the dredge

canadianolympicdredge2008Jul15_5865
Before moving next door to Midwest Energy Resources in Superior to load coal yesterday, the Canadian Olympic discharged limestone at the Hallett #8 Dock (above). You can see the Olympic’s self-unloader hanging just above the pile of limestone as its conveyor system moved the limestone from the boat’s cargo holds up and onto the pile. The other thing sticking up in the air, just left of middle, is the crane from the Marine Tech dredge. They were doing maintenance work just beyond Midwest Energy in an area where the high traffic at Midwest kicks up material from the bottom of the river. It can block the channel if not periodically dredged.

Going to Two Harbors on a dredge

misslauracranebardge270416-1-043
The crane barge Dean R. Smith was pushed out of the Duluth piers by the tug Miss Laura early Monday evening. In the picture above they are just beyond the North Pier Light, making a turn toward Two Harbors. Owned and operated by Marine Tech, a local dredging and construction company, the rig will spend two to three days in Two Harbors doing routine maintenance at the CN taconite dock. The rig carries a crew of 4. They do double duty as the crew for the rig when it is under power on the lake and as the work crew for the project. On some jobs, they would spend the night on the tug, but since Two Harbors is close by, they will return home each evening.
