RV Lance
The Department of Arctic Technology at UNIS regularly charters RV Lance for research cruises in the waters around
Svalbard. In 2012, SAMCoT participated in an expedition to the western Barents Sea on 16-25 April. The cruise was conduct-
ed by 27 researchers and students, headed by Professor Aleksey Marchenko. SAMCoT provided financial and research sup-
port. A number of experiments were performed beyond the Spitsbergen shoreline and in the waters around Hopen Island:
• Ice trackers were deployed on sea ice to provide statistics on drift patterns and speeds
• Uniaxial compression tests were performed to give mechanical strength of ice; borehole jack tests were also performed
to provide mechanical strength values
• Ice ridges were surveyed at the surface by laser scanning and the internal structure mapped by manual drilling
• Beam tests were performed to estimate the flexural strength of the ice
• The breaking patterns in the ice-ship bow interaction zone was monitored by video cameras
• Sea currents and CTD profiling was also a part of the research programme
An important part of the cruise was to give the students “hands-on” and experience operating in the Arctic.

KV Svalbard
KV Svalbard is a Norwegian Coast Guard icebreaker that
operates in the Norwegian Arctic. The performance of KV
Svalbard in ice was studied by SAMCoT researchers, and
a set of full-scale experimental data was collected in the
Fram Strait from the 8th to the 18th of March, 2012.
During the survey, participants tested the performance
and manoeuvrability of the vessel in different ice condi
tions and in open water, studied the interaction between
the ship and ice at the waterline, analysed ice manage
ment scenarios and deployed buoys to monitor and study
sea ice drift. “These tests provided us with necessary data
to validate and calibrate the numerical models we have
created for floaters in ice,” said Dr. Lubbad.
Joining Dr. Lubbad on the survey were SAMCoT PhD
candidates Wenjun Lu and Qin Zhang, as well as Runar
Hassel, Stig Rune Søberg and Kristina Simankova from
Trondheim’s Ship Modelling & Simulation Centre (SMSC).
