Astilleros Gondan to build Østensjø LNG-fueled tugs

FEBRUARY 2, 2015 — Spanish shipbuilder Astilleros Gondan has been awarded the newbuilding contract for the three LNG fueled escort tugs that Norway’s Østensjø Rederi is building for operation at Statoil’s Melkøya terminal.

As we reported last week, the Robert Allan designed tugs will have Wärtsilä dual-fuel (DF) engines integrated with a customized gas storage and supply system also supplied by Wärtsilä. Though they will primarily burn LNG (Liquefied Natural Gas), the Wärtsilä DF engines provide the flexibility to select the most suitable fuel according to availability, price and local environmental restrictions.

The three new escort tugs will operate in icy environments of down to to -20º C.


With dimensions of 40 m length and 16 m beam, they will have a bollard pull of 100 tons and escort steering force of 155 tons.


Delivery is set for  first half of 2017



Østensjø Rederi says Astilleros Gondan was chosen to build the tugs based on an extensive evaluation taking into account; experience, quality, price and delivery time.  Østensjø Rederi  says it is very familiar with Gondan as the shipyard has delivered eight vessels to the company since 2005 — five tugs of this size and three large PSVs.
