Abstract
A system for acquiring data in an offshore environment comprises an elongate composite tension member having a longitudinal axis, an upper end, and a lower end. In addition, the system comprises a buoyancy module coupled to the upper end of the composite tension member and configured to apply a tensile load to the tension member. Further, the system comprises a base coupled to the lower end of the composite tension member. The base is configured to secure the tension member to the sea floor. Still further, the system comprises a plurality of composite stringers coupled to the buoyant module and disposed about the tension member. Moreover, the system comprises a plurality of instrumentation systems configured to measure environmental or geological data. The instrumentation systems are coupled to the stringers.
