BRIGHTER LIGHTS?

"Notice how the lights now seem brighter?"

A joke, of course, but Hoyt may have correctly put his finger on the future dependability of the Island's power source.

As of 1:00 p.m. Friday, Lee Engstrom reported, the Island's power shifted from the old submarine cable to the new cable, and without a hitch.  Both men serve as directors of the REA Board, and they, as well as Manager Robert Cornell and other REA crew and Directors, should feel both relieved and proud of this accomplishment.  Lee accompanied contractors daily during cable repair and cable laying activities in order to properly document with photos this past year's events.

Monday, Feb. 4, Wisconsin Public Service crew spliced
new cable, connecting both old and new supply cables 
to this switch box, and to the line that runs underground,
leading to theElectric Co-op sub-station.

Problems began with the unanticipated underwater cable failure in June, and the need to repair that break as quickly as possible.  This initiated multiple steps in logistics and timing:  underwater divers; a cable splicing crew; a work barge with tug to lift and cut the failed section and then reset the repaired cable back in place.

In the fall of 1980, cable arrived on a barge, but so had
winter, and it would be spring before weather permitted
laying the first underwater electric cable for the Island.


The checklist was long, the cost was unexpected, and the long-term outlook, given the old cable's status, remained one of uncertainty.

That cable had been laid in spring of 1981, but given the low draw compared to its rated capacity, and given exclusive use in fresh water, expectations were for it to have a longer life span.  However, along the relatively flat rock bottom west of Plum Island, and at a depth of 40 feet, ice nevertheless had shoved and abraded the cable over time.  Fortunately, this break resulting in an instant power outage on the Island occurred at the start of our summer and in warmer weather.  This made cable location and repair easier than if it had been mid-winter.  Generators were then started and placed on line, but at a significant cost in daily fuel consumption.  An emergency CAT generator had to be located and trucked to the Island when one of the two REA units suffered failure of an air intake casting. This series of events even further compounded the main cable repair challenge and stretched limited resources of the Co-op team.

Almost as soon as cable failure occurred and simultaneous with the on-going repairs that would stretch to ten days' time, the REA's plan of action was exercised, led by the Electric Co-op's manager, Robert Cornell.   It called for the procurement of a new cable, to be manufactured by an east coast firm.  It would be of length based on a new route, different from that previously used.  Rather than route the cable around Plum Island as was previously done, a route that might once again subject the cable to shoving ice fields, this time the cable would be laid inside a polyethylene sleeve and trenched to at least 20-foot depth, and it would run from Northport to Plum Island.  Then the cable would cross Plum Island underground, using less expensive, land-based cable material trenched in soil.  Near the old Plum Island Life Saving Station it would reenter the lake and from there cross to Washington Island. It would come ashore alongside the 1981 electric cable, in an easement adjacent to the former Goodwin Berquist property.  Now, a new switch box links both old and new underwater cables to terminals that can connect to the underground cable leading inland to the REA distribution center, on Main Road.

Like any large project, timing is everything:  to obtain needed cable from manufacturer before freeze up, when ice covers the lake and makes waterborne construction impossible; trenches dug from shore into the water at four locations, with a ten-inch polyethylene sleeve buried and ready to accept the cable at each entry point; and also, to lay the Plum Island segment of underground cable while landing there with men and equipment was still easily managed.

The new cable arrived by truck in Sturgeon Bay, later than expected and promised, on enormous reels.  It was loaded on contractor Roen's work barge at Bay Shipbuilding.  This delay in cable delivery pushed back laying new cable until the middle of December.  But then, by good fortune, a series of windless, warm days permitted the Roen crew to successfully lay the two segments of underwater cable.  Only a few hundred feet of surplus remained on either side of the runs, in the event of course deviation while tug and barge laid cable.

A separate company monitored the laying of the cable with underwater cameras to assure the new electric cable did not pass over large, sharp rocks, or suspend, unsupported, over wide crevices.

Dec. 15 - A brief return of warm weather and light air enabled Roen 
Construction to lay the two underwater cable sections without a hitch. 
Divers connected cable ends to a loom attached to a heavy wire rope, 
then helped feed the end into the conduit as it was pulled ashore 
through the sleeve by Tom Jordan's excavator.


The splicing of cable segments to one another, and to the Wisconsin Public Service feed at Northport, was completed, then, this past week, with the new cable becoming "live" early Friday afternoon.   The old cable remains energized, just in case, under a greatly reduced load, in order to remain dry and usable.

  Sections of plastic conduit were bolted together into approx. 
500-ft. lengths and laid out on the Potato Dock prior to being 
towed into position and sunk into trenches dug at each exit/entry point.  
Red conduit is for fiber-optic cable. (Taken in early December.)



Congratulations on a major effort, a "well done" to all involved.

Now, what about the fiber optic cable laid alongside the new electrical cable?  It's caused Co-op manager Robert Cornell the least concern, up until now.   As this project winds up (some back-filling still necessary where the cable enters/exits near shore at Northport) it, too, will get attention.

AGAIN ??

Seems like the same old story, digging, trucking and muck.  
But each day holds newchallenges.  Current dredge spoil 
totals are now slightly over the half-way mark
objective in terms of volume of spoils, and

not quite half-way in bottom area to be dug.
Detroit Harbor, Washington Island

-  Last Day, 2012  -

By far the largest dredging project yet undertaken by the Ferry Line is the deepening of waters adjacent to the Island Potato Dock.  In the warmer weather of any other season, a successful project conclusion would be assumed as only a matter of time and money.  But with winter coming on, short daylight hours, temperatures sure to drop below the pleasant upper 20s of the past weeks, and equipment and people increasingly under strain, achievement of our goal is still a ways off.

"No, not another blog on dredging," was a comment I received, directed toward the series of reports with similar themes of late.

I can't help myself!  I find the combination of big equipment, the project scale and challenges too intriguing to pass up.  And, that doesn't begin to address the alternatives if the Ferry Line and the Island can't have one, safe ferry landing site come real winter.  Not succeeding is just something none of us can begin to contemplate.  So... its dig and haul, dig and haul, until sufficient material is removed.

"Why is this being done so late in the season?" is one question we've been asked.

The project as it stands on this last day of the year is a culmination of action begun months ago.  First, as water levels were monitored, we hoped the drop would not lead to extremes requiring immediate dredeging.  The cost of such activities was huge enough that we waited until we were sure certain there were no other options besides expenditure for dredging.

The paperwork - the filing of permit applications for state and local approvals that allow a project like this legally go forward began in early October.  That was when falling lake levels sounded serious alarms for the consequences of the coming winter's navigation.  We were fortunate in the permitting process to have had the prompt and full cooperation of regional WDNR administrative and Door County Zoning personnel,  We believe they helped to speed the permitting for this project more than would typically have been the case.  Our permits were received in mid-December, and at that time we had already set a tentative start date for digging.

There was also the verbal lining-up of a marine contractor.  Although we had Mike Kahr on the way, after he completed work at another site in Fish Creek, the scope of this project and the slippage of time brought further concern.  That led to our asking Roen by the middle of December to consider our job once their work in Egg Harbor was completed.  This they agreed to do.   We were fortunate to have the understanding and support from both Roen and Kahr.  Everyone understood that this dredging needed to be done ASAP.   As it happened, we are relying on the equipment of each marine contractor.

Critical in this project, too, is the willingness of Island men who own and drive dump trucks.  They've been willing to operate their trucks, loaded ten yards at a time, for five or six round trips - about 3.5 hours - per material barge load.  They appear at the Potato Dock after an advance phone call from Rich Ellefson.  Rich then works either on shore coordinating the trucking, or he monitors dredging progress and operates a skidster to assist cleaning out corners on the material barge.

Without the help of Pete Nehlsen, Dave Hanlin, David Small, Mike Jorgenson, Tim Ervin, Tom Jordan, Drew Rainsford and Jon Mann, plus one of Mike Kahr's dump trucks driven by Joel Gunnlaugsson (or myself, one day), and Hoyt Purinton supervising the pit dumping activities, the dredged material would soon stockpile on the barge and the entire project would be slowed.  Thanks also to Julian Hagen for consenting to receive spoils at his gravel pit.  Because the Hagen site is close, a truck can make the round trip in 30 minutes or less, when all goes smoothly.

Dave Hanlin, Rich Ellefson, Con McDonald
lent a hand in pulling slack on the hoist cable.



Rigging the cable for the clamshell used for offloading
stopped production Saturday evening for about 30 minutes.
Rich Ellefson, Dave Hanlin and others assisted Roen crew in
refastening the cable.


Tom Jordan drove his dump truck for every off-load, and he's also operated the Kahr excavator.  Saturday, I observed Tom as he climbed down from the excavator following a continuous, five-hour shift of digging.  (The excavator didn't have heat in the cab.)  Cold and stiff-legged, he crossed the barge deck to get behind the wheel of his truck.  Later that evening, while the bucket cable was undergoing repairs,  he laughed and joshed with other drivers, surprisingly fresh and enthusiastic.


View from behind the wheel of a Mack.  I kidded Pete Nehlsen about
"catching up with me," when actually he'd lapped
me earlier on the pit turn-around.   Good drivers can haul, dump, re-do
tailgate "sludge locks" and be positioned for
another load in less than 30 minutes.  It's no space shuttle cabin, with
half-a-dozen buttons and as many procedures for dumping, but I 

barely kept up.   A clutch failure sidelined my truck later, that evening.
Now, with a two-day holiday break coming, Roen's lead man Don Sarter indicated he'll return after New Year's with enough men for two shifts to enable round-the-clock digging.  The Roen crew is just as concerned about finishing the job for the Island as they are to complete their season and get their equipment safely back to homeport in Sturgeon Bay.

So, thanks for indulging me in yet one more report on dredging.  It's critical to the well-being of Washington Island to have this work done.  We could say that the stakes have never been higher.  For that, we're thankful for the willing participation of many hands during the recent days.
