Anyone with the engineering data that backs up the tube trimming exercise? Because I see it as a thermal solution to a mechanical problem. When the oil's cold, (let-down, cold-soaked cruise,) it will melt icebergs ahead of the Titanic?
The problem is defined as Ice related; no new research is available to mitigate what is demonstrably a potentially life threatening occurrence.
Of course the tubes are the bottleneck, they still are. An elegant "solution" to be sure, but for which problem?
Why not a wet particle separator upstream the "heater"?
