TOTE Company History : TOTE Company History Founded in 1975 by Sun Company
SS Great Land maiden voyage September 1975
May 1976 TOTE adds second vessel for two sailings per week
TOTE acquired by Saltchuk in 1982
July 1991 SS Northern Lights purchased and modified
Contract with NASSCO for two Orca Class Ro/Ro vessels December 1999
April 2003-Midnight Sun delivered
August 2003-North Star delivered
TOTE Alaska Operations : TOTE Alaska Operations Niche Ro/Ro liner service characterized by:
Fast 24 kt ship 66 hour transit
High cargo productivity 10 hour turnaround
Flexibility loading - all equipment types
Vehicles
98% average on-time record over 5 years
Highway and rail connections throughout greater Alaska and Lower 48/Canada
These are recognized as key requirements of any successful Short Sea Service
Alaska Transportation Challenges : Alaska Transportation Challenges South Central Alaska’s freight arrives by:
Liner Vessel - 67%
Barge - 26%
Overland - 7%
1,450 nautical miles one way (Tacoma-Anchorage)
Wind gust to 100 knots
Seas to 60’
Cook Inlet
Ice-choked 5 months of year
6 to 7 knot tidal current
35’ tidal range

Design is therefore a compromise trying to satisfy as many conditions as possible.
However, TOTE’s Ponce class vessels were designed for the U.S. East Coast to Puerto Rico trade : However, TOTE’s Ponce class vessels were designed for the U.S. East Coast to Puerto Rico trade
Slide9 : The sea spectra for the Gulf of Alaska have been intensely researched by oil companies who operate tankers to Valdez, Alaska and that spectra was made available to TOTE.
We also have 25 years of operating experience in this run.
Seakeeping model tests involve many scaling factors and thus may, or may not, represent what actually happens in full scale.
TOTE therefore paid an additional cost to test the existing ships in the same:
Model Tank
Model Scale
Sea Spectra
As the new ship would be tested.
