Wireless networks, such as 5G (and future 6G) networks, can recognize opportunities to enhance message performance by analyzing fault types in real-time, and selecting an appropriate mitigating modulation table accordingly. Noise patterns causing adjacent-amplitude faults and adjacent-phase faults indicate the need for different modulation schemes, while the large non-adjacent faults from pulsed external interference lead to yet a different choice. Disclosed examples show how to select an appropriate mitigating modulation table through fault analysis of failed messages. By selecting and switching to different modulation tables according to the types of message faults experienced by user messages, network operators can reduce message failure rates and increase overall throughput while reducing average delay per message, according to some embodiments.

The disclosure provides a tension leg platform (“TLP”) with a plurality of buoyant pontoons suitable for highly disturbed seas that can expand the stability of the tension leg platform by extending at least one buoyant pontoon beyond an intersection of two pontoons. In at least one embodiment, the location of the column can be decoupled from the customary end of the pontoon. The tendons can be located at the ends of the pontoons extending beyond the intersection. In some embodiments, such as four-column TLPs, the pontoons can be extended orthogonally relative to an adjacent pontoon. The extending pontoon increases a buoyancy of the pontoon, increases a pitch stability of the TLP, and increases quayside stability. The extended pontoon can be structurally intersected with the adjacent pontoon to strengthen the extended pontoon and reduce the failure mode of such structure.
