Abstract
A utility bridge suitable for connecting offshore facilities such as offshore platforms is disclosed in which a plurality of helical pipelines provide flow communication between the facilities and relative movement of the facilities in response to environmental forces is provided for by helical pipelines with torsion expansion loops supported by a substantially rigid frame of the utility bridge which has means to prevent coupling of dynamic forces between the respective offshore facilities.
