In brief
INS Jyoti (A58) (meaning: sacred light) is the third of four Komandarm Fedko-class replenishment oilers. She was modified for naval use and is now being operated by the Eastern Naval Command of the Indian Navy. Jyoti was the largest ship in the navy until INS Vikramaditya (R33) was commissioned in November 2013. It is the third largest ship in the Indian Navy after the aircraft carriers INS Vikrant and INS Vikramaditya. Its primary role is fleet replenishment and sustaining blue-water operations. It was later fitted with close-in weapon systems for self-defence.
It is a major force multiplier in sustaining the navy's blue water operations. It can increase the range of a naval task force without tanker support from seven days and 2400 nautical miles to 50 days and 16,800 nautical miles.

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 21,585 gross tons, INS Jyoti is the 25,583rd largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 3.6 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 611 naval / patrols held here, it ranks 33rd by tonnage — larger than 88% of that group. Their median tonnage is 1,325 GT, and the largest tenth begin at 23,606 GT. The flag most often flown by this group is United States (136 ships). The yard that appears most often against it is Austal, with 33 hulls on record.
India is the country of registry for 968 vessels in this directory, of which INS Jyoti is the 250th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (514 ships), and the median vessel measures 3,306 GT. Browse every ship flagged India.
Narrowing to both dimensions at once, this registry holds 8 naval / patrols flying the India flag, of which none is larger than INS Jyoti.
INS Jyoti was built in 1996, making it 30 years old. It is one of 1,254 hulls in this registry delivered that year, a cohort whose median tonnage is 7,254 GT; within it this ship is the 364th largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.
The registry attributes 14 vessels to Admiralty Shipyards, with a median tonnage of 13,817 GT, delivered between 1956 and 2017. See the rest of that yard’s output.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9063029 this registry holds 45 other vessels, whose median build year is 1993 and which range from 1992 to 1997. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1996.
Its IMO number, 9063029, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 0×6 + 6×5 + 3×4 + 0×3 + 2×2 = 109 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
