Flame SDA

What you get

• Laboratory analysis of scavenge drain oil from every cylinder, tested in a laboratory accredited to ISO/IEC 17025, to ASTM, ISO and IP methods: iron, total and magnetic, wear metals, residual BN, water, contaminants and additive elements.
• Every result corrected for dilution by system oil, fuel and water with Flame ADT and reported on a cylinder-oil basis, the same correction that Flame Diagnostic applies. The kit takes a sample of the fresh cylinder oil and of the system oil with the drain oil, as Everllence SL2023-738 asks, so that the correction is referenced to the oils actually in the engine.
• For each cylinder: corrosive and abrasive wear told apart, from magnetic and total iron read against residual BN; the trend against the vessel's earlier samples; comparison with the other cylinders; and a stuffing box or water finding when the sample shows one. A short comment wherever something needs attention.
• The crankcase system oil, reported alongside the cylinders: contamination, wear metals, and whether the stuffing boxes are keeping the cylinder residues out of it.
• Practical lubrication guidance: whether the feed rate and the cylinder oil BN suit the fuel in use, read from the drain oil.
• An optional fuel purifier check: fuel sampled before and after the purifiers (points 1 and 2 on the fuel system drawing) and analysed for catalytic fines and water. The difference shows how well the purifiers are working. A third sample before the engine (point 3) extends the check to the service tank, showing whether the fuel that reaches the engine is still as clean as the fuel that left the purifiers.
• Sampling kits, submission forms and courier documentation, as for Flame Diagnostic.

Inside a Flame SDA report

What it leaves out

Flame SDA does not use engine performance data, and its fuel samples go no further than the purifier and service tank check, so it cannot tell you why a unit's combustion has changed, verify the figures the ship reports, or read the fuel against the drain oil. It tells you, on the right basis, what the drain oil shows and which units need attention. For the full diagnosis, the same vessel can move to Flame Diagnostic at any time, and the sample history carries over.

Who it is for

Fleets that want the engine designers' recommended scrape-down oil reporting in place, with the results interpreted independently of the lubricant supplier. Laboratory reporting is widely available; an independent reading on a cylinder-oil basis is what Flame SDA adds.
