Canadian tug design specialist Robert Allan Ltd (RAL) reports that it has been awarded a contract to design a new version of the successful Z-Tech® 4500 tugs for the United States Navy (USN).

The USN already has six vessels of this design, known as the YT 802 Class, in service. This first group were delivered between 2009 and 2012 and are in use in the Pacific Northwest and Japanese waters. Four new tugs (with an option for two more) will be built in Anacortes, WA by Dakota Creek Industries. The hull form for the new vessels will be essentially identical to previous versions of this class of vessels, but with deckhouse changes to suit new EPA Tier IV engines, which require significantly larger exhaust emission systems. Changes to the fendering system will incorporate feedback from operators on the existing vessels.

In another development, RAL says that Saam Smit Towage Canada (SST Canada), a joint venture between Boskalis of the Netherlands and Saam SA of Chile, has recently completed the purchase of two new RAstar 3200 escort tugs from Hong Kong’s Cheoy Lee Shipyards. SST Grizzly and SST Orca will depart Cheoy Lee’s Hin Lee shipyard next week, to arrive in Vancouver in early November of this year. Upon arrival, these two new escort-rated tugs will begin operations in the southern waters of British Columbia.
