a fundamental deviation from 30 years of traditional semi-submersible
The common spaced-apart two-pontoon construction with integrated
trusses and vertical columns supporting a square deck structure
has been discarded in favour of a completely new design based on
a symmetric hexagonal shape from baseline through the upper deck
level. This results in a very rigid construction with superior strength
properties and impressive operational assets.
The Symrig geometry offers ample deck space and provides for a variety
of operational functions and arrangements, while retaining improved
qualities in terms of the working environment and safety for personnel.
