 The Polar Technology Office of Science and Technology Corporation offers a
broad range of research and engineering services
associated with marine activities in polar and subpolar
regions. The office has been providing these services to
government and industry continuously since 1991. The
work in support of our clients has encompassed dozens of
ship trials in Arctic, subarctic, and Antarctic regions,
and hundreds of projects in polar technology completed
over that time period.
-
The STC Polar Technology Office has expertise in ship
navigation in ice, design criteria and performance
assessment for ship powering and loads in ice, ice
structure interaction design criteria and assessment,
penetration of ice, polar environmental definition, and
polar logistics support. Analytical studies include:
- - Mathematical modeling for resistance in level
ice, pack ice, brash ice, rubbled and ridged ice
- - Ice load design criteria and prediction for
ships and offshore structures as well as
ice-structure and ice-propeller interaction
- - Propulsion machinery control and steering
system response during operations in ice
- - Polar and subpolar loading and transportation
simulation in ice
- - Topside icing prediction.

The STC Polar Technology Office plans,
manages, and validates laboratory studies using various
facilities throughout the world. Members of the Office
have tested:
- - Ships, offshore structures, and
unconventional vehicles in all types of ice
conditions
- - Penetration of submarine sails,
sensors, buoys, and weapons.
- - Ice properties
- - Machinery, equipment, and
instrumentation systems in low temperatures
- - Propellers for icebreaking ships
- - Pressure-area relationships have
been investigated at model scale for the
ice-structure interaction process.

 The STC Polar Technology Office offers
conceptual, preliminary, and prototype design services
as well. These services include:
- - Definition of ice and environmental
conditions in polar and sub polar regions
- - Polar program planning and management
- - Structural design for ships and for
moored, dynamically positioned, and gravity offshore
platforms
- - Propeller and propulsion system
design, rudder and steering system design, machinery and
equipment for polar applications
- - Instrumentation systems for polar
applications
- - Finite element modeling of structures
exposed to ice loading.
-
 STC Polar Technology Office is skilled
at instrumentation and data collection systems for
environmental conditions, ship performance and
maneuverability, and ice loads measurement on ships and
offshore structures. Full scale testing has included:
- - Ice properties and dynamics from
the ice edge to the Pole in the north and to the
Antarctic Continent in the south.
- - Ship resistance trials in all
types of ice conditions
- - Ice interaction with hull
structure, propellers, and appendages
- - Ship vibration response during
icebreaking
- - Trafficability of surface ships
in ice conditions
- - Measurements of topside icing,
and effectiveness of anti-icing and deicing
techniques.
- - On-ice engineering & logistics including under-ice ROV operations
- - Personnel safety and survival in
polar regions
A Few
STC Programs
-
STC
currently supports the U.S. Coast Guard with design
reviews and ice trial hull and propulsion testing
for the Great Lake Ice Breaker (GLIB).
-
STC is
currently developing the conceptual design for the
next generation polar research vessel.
-
In early 2006, three
members of the PTO assisted in the annual break-in
to McMurdo Station, Antarctica.
-
On August 22, 1994, two
senior engineers from the STC Arctic Technology
Division were part of a scientific team aboard the
first ever ships to reach the North Pole. A
map (340.6 Kb)
charting the expedition's course is available.
