The phenomenon of sea ice – infrastructure
interaction is seldom understood. The design of a new wharf at Rothera sets
many challenges for the design team to ensure robustness and longevity of the structure
in this most extreme environment. The presentation details the journey from
evaluating the impacts of moving sea ice, to selecting appropriate design
criteria. Reflection is made on the lessons learnt from performance of the
existing structure as well as exploring the design solutions that have set a precedent
for modern polar maritime engineering.
