When ever the
subject is power generating plants, ABB (Asea
Brown Boveri) is a name recognized around the world. Their power
generators are installed in many countries around the world.
All of the
components for this project originated in Sweden. Prior to the
commencement of this project, Ronald Hiemann traveled to Sweden
to meet with the management of ABB to discuss project details.
Additional meetings were held with J.H. Bachmann of Bremen,
Germany, the Seajet partner for this project. During the 3 years
of this project, Seajet dealt with cargoes arriving on 7
break-bulk charter vessels, which docked at the Mystic Pier
terminal in Charlestown, adjacent to Boston, MA.
Along with the
break-bulk cargo, every time
M/V Opsterland
docked in Boston, she also carried
2 ABB transformers. Each one
was the size of a single-car garage and had a weight of about
145 metric tons.
There was no local crane available to handle the unloading of
such heavy equipment. There was only one crane available on the
East coast of the USA to handle such heavy loads. Seajet hired
this
swimming crane in Baltimore for a period of 1 year. It was
tied-up in a side channel next to Mystic, right below Tobin
Bridge. The crane was used once every 2 months to unload 2
transformers off of the Opsterland. Each lifting operation was
billed at a rate of $35,000.00
To move the transformers to Ayer, MA (the
location of the
New
England Hydro power station), required special equipment. The
only rigging company able to handle such heavy equipment was Almas International out of California. The
special trailer is
shown in the photo above. Between a puller and a pusher
truck, the entire rig was about 150 feet long! The delivery from
Charlestown to Ayer happened at walking speed, literally. It
could be done only on weekends and to travel a distance of about
46 miles took about 9 hours! The rig was not allowed to leave
Charlestown before 2300 hours on Saturday and the move had to be
completed by 0900 hours on Sunday morning. State and local
police escorts were required and every time, utility trucks from
the electric, telephone and cable TV companies were on hand to
lift wires where ever they were hanging too low to allow the rig
to pass under. Each transformer move was billed by Almas at a
rate of $145,000
A year after this project was over, ABB was contracted to
deliver 2 additional but much
smaller transformers. Seajet
handled this delivery through the Port of Newark, NJ and
transported them on the
railroad to Ayer, where they were
unloaded from the
railcars onto special equipment hired from Shaughnessy & Ahern in Boston.
