“…Surface to bottom cabled moorings are currently under development for high power and data bandwidth from buoy to anchor. MBARI, together with Woods Hole Oceanographic Institution (WHOI), tested the design and mechanical loading of a surface to bottom cabled mooring system as part of the MBARI Ocean Observing System (MOOS) [19]. These types of cabled systems have the capability to harvest and store solar and wind power in batteries mounted in the surface buoy.…”

This paper discusses the current state of the art systems of real time telemetry on oceanographic moorings and describes the design requirements for making acoustic modem data telemetry a more widely used form of data telemetry for moored oceanographic applications. We present the design of a low cost 'mooring modem' and the results of an initial pool test for its prototype. Based on these results, we describe how the mooring modem meets the design requirements for moored oceanographic applications by looking at how it meets the requirements for a specific mooring example -the SB CHARM. We conclude by presenting the future work required to create a prototype mooring modem, which will be tested on the CHARM mooring. The end goal is the production of a cheap, low power acoustic modem for real-time data collection in moored oceanographic applications.

“…However, these cables can be subjected to high mechanical loading from buoy movement due to winds, waves, tides, and currents, resulting in tension and cable breakage [19]. EOM cables are very expensive (on the order of $50-100K per deep water system) and time consuming to replace, in terms of finding emergency ship time and personnel.…”

“…Molded plastic boots, serving as bend stiffeners and arranged over the cable next to its termination, are one method of minimizing bending of the cable at these points. A molded chain section above and below the ends of the EOM cable can also help reduce the effects of bending (Paul et al, 1994;Hamilton et al, 2003;Kemp, 2004).…”

“…If the fishbite protection does not extend the entire length of the cable, the transition region needs to be managed carefully to avoid an abrupt change in cable stiffness. The cable dynamics at such a transition are not well understood, but there is evidence that severe bending forces may result (Hamilton et al, 2003).…”

A B S T R A C TMooring systems that deliver power and data communication to sub-sea instrumentation figure prominently in future plans to build ocean observatories. Currently, this technology is immature and technological advancements need to be made before such systems are ready to be routinely implemented. This paper describes the current state of the art in mooring systems appropriate to the deepwater ocean observatory context and outlines the technological challenges that need to be addressed in order to realize moored ocean observatories as envisioned for the next generation of ocean observing systems.

“…During the 1960s moorings were deployed in benign locations where currents were the dominant forcing and engineering design only needed to consider static tension. By the 1980s moorings were being deployed in rougher environments where wave forcing dominated and design needed to include cyclic fatigue (Trask 1995;Grosenbaugh 1995;Hamilton et al 2003), as well as static loading.…”

The Southern Ocean Flux Station was deployed near 478S, 1408E. The extreme wind and wave conditions at this location require appropriate mooring design, which includes dynamic fatigue analysis and static analysis. An accurate estimate of the wave conditions was essential. A motion reference unit was deployed in a nearby test mooring for 6 months. The motion data provided estimates of significant wave height that agreed well with the Australian Bureau of Meteorology wave model, increasing confidence in the model performance in the Southern Ocean. The results of the dynamic fatigue analysis using three input wave datasets and implications for the mooring design are described. The design analysis predicts the fatigue life for critical mooring components and guided the final selection of links and chain shackles. The three input wave climatologies do not differ greatly, and this is reflected in minimal changes to mooring components for each of the fatigue analyses.
