Brunvoll’s new Rim-Driven Thrusters have
been running smoothly for thousands of
hours in demanding North Sea operations
2007 “Edda Fram”
2009 “Edda Frende”
Bow: 2 x LowNoise Tunnel Thrusters FU80 LRC 2250 1,200 kW
1 x Rim-Driven Thruster RDT 1750 800 kW
The first large Rim-Driven Thruster (RDT)
was installed in “Edda Fram” in 2007.
Brunvoll developed, engineered and produced
this innovative RDT 1750. It was installed with
resilient mounting to supplement the two
existing LowNoise tunnel thrusters
on the pioneering PSV “Edda Fram”
owned by Østensjø Rederi and
designed by Skipsteknisk AS.
All the thrusters functioned smoothly.
Østensjø installed an RDT on the sister
vessel, “Edda Frende”, in 2009, and has now
ordered a new RDT for a third newbuilding.
