available work windows due to busy terminal operations added to the complexity of construction
and contributed to the higher construction cost estimate.
In 2006 and 2007, there were two major equipment and structural failures on Towers 1 and 4,
which were repaired. Prior to 2006, there was a failure to Tower 5, which was repaired. These
failures raised concerns for additional failures on Towers 2, 3 and 5 and led to this tower
strengthening project.
ADDITIONAL BACKGROUND:
T-86 is an export grain terminal that receives, stores, and loads grain to bulk ships for export to
Asia, notably China, and other foreign markets. Constructed in the late 1960s, T-86 was
originally designed to export wheat. Today it handles primarily corn, soybean and sorghum from
the Midwest.
T-86 is unique in its ability to load bulk ships directly from rail or via its network of silos. Direct
loading of ships from railcars reduces handling costs and breakage of product (preserving its
quality). Silos enable products to be received from rail prior to arrival of the ship, reducing costs
associated with demurrage of railcars. Silos also allow a variety of types and grades of grain to
be received. Ship holds can be filled with different commodities and by blending various grades
from the silos, a shipment can be prepared to meet exacting standards.
Product is loaded to ship holds via a network of conveyors, which feed five spouts. Each spout
is mounted to a tower and can be articulated, much like the boom of a crane, to distribute product
evenly throughout each hold. Typically, two spouts operate at any given time during loading.
However, to fill all of a ship’s holds, all five spouts are used intermittently to eliminate the time
and expense of repositioning the ship to fill its array of holds.
Based on an analysis of the three failures of grain spouts on Towers 1, 4 and 5, it has been
determined each failure occurred for unrelated reasons. Nevertheless, as a risk assessment
measure, a thorough review of all five towers, spouts and assemblies was performed. Repairs of
the failed Spouts #1 and #4 were completed including a fix to Spout #5 in 2009.
Towers 2, 3, and 5 and their ship loading systems were inspected in 2009 and are approved for
operation, subject to monthly inspections and testing.
Impacts to operations from unexpected spout/tower failures have been and could be substantial.
They result in facility shut downs to secure the Terminal prior to resuming operations on an
interim basis with a reduced number of loading spouts. The facility subsequently must be shut
down to undertake repairs. Such shutdowns reduce throughput volumes (and revenues to the
Port and Tenant) and increase demurrage charges for railcars and vessels, alike. Completion of
the requested improvements would reduce risks for the short and longer terms.
