Spain’s NAVAREA III coordinator has now printed a numbered Black Sea drilling warning that cancels last summer’s Abdulhamid Han box and relocates the same named rig onto a later four-corner plot through 28 January, not a reprint of Tuesday morning’s dedicated IMO 131-count and not a second Britoil Centurion track. The working primary retrieved this run is the English body of NAVAREA III 0170/26, now on the coordinator board as PLATAFORMA ABDULHAMID HAN with a printed cancel of 28 January 2027 at 20:55: BLACK SEA. 1- DRILLING OPERATIONS BY ABDULHAMID HAN RIG (IMO 9705093. MMSI 271050408), SUPPORTED BY ALTAN, KORKUT, MURRUVET ILHAN, MIHRIMAH, OSMAN BEY, ORHAN BEY, ERTUGRUL BEY, AYBUKE, SANCAR, PSV YESLKOY, PSV FLORYA, MENDERES, ZORLU AND POLATKAN. BETWEEN 09 NOV 26 UNTIL 28 JAN 27 IN AREA DELIMITED BY: 43 02.34N-031 34.81E, 43 04.72N-031 34.75E, 43 04.78N-031 39.98E, 43 02.40N-031 40.03E. 10 MN RECEIPT REQUESTED. CANCEL THIS MSG 282059 JAN 27. 2.- CANCEL NAVAREA III 0122/26 AND THIS PARAGRAPH. Hold the English YESLKOY spelling. That is Tuesday afternoon’s working NAVAREA III drilling instrument. It is a named-hull relocation with a 10-nautical-mile receipt, not a weekly group-45 rewrite of dedicated 0168/26, not a Hormuz Attack PDF, and not this morning’s dedicated Elefsina parachute disc.
The warning is a NAVAREA III product. It is not NAVAREA IX 434/26. It is not a Bulgarian NAVWARN 815. It is not UKMTO 200-26. This morning’s dedicated IMO board remains 131 confirmed incidents as at 9 November, with 25 seafarer fatalities and HUDA as the top named row. Masters who brief Tuesday afternoon as a Black Sea exclusion zone, as a completed RAM status on the NAVAREA text, as Amasra 7/10 field names promoted onto 0170/26, or as weekly group 44 already reprinting 0170 in its 2026 list will have over-read a four-corner drilling watch. 0170/26 tells the bridge which hull, which IMO and MMSI pair, which support spread, which dates, which four corners and which 10-nautical-mile receipt to plot. It does not print a VHF working channel, a flag, a diving window, a restricted-manoeuvre line, or a harbour-master closure. Tuesday morning’s unused folder held this English body as unused as dedicated. Tuesday afternoon converts it.
What 0170/26 actually printed
The hydrographic text is short and is the working primary. Black Sea. Drilling operations by Abdulhamid Han rig, IMO 9705093, MMSI 271050408, supported by Altan, Korkut, Murruvet Ilhan, Mihrimah, Osman Bey, Orhan Bey, Ertugrul Bey, Aybuke, Sancar, PSV Yeslkoy, PSV Florya, Menderes, Zorlu and Polatkan. Between 9 November 2026 until 28 January 2027. In area delimited by: 43 02.34N-031 34.81E, 43 04.72N-031 34.75E, 43 04.78N-031 39.98E, 43 02.40N-031 40.03E. 10 MN receipt requested. Cancel this message 282059 January 2027. Paragraph 2: cancel NAVAREA III 0122/26 and this paragraph. Stay with that wording. The coordinator printed a sea. It printed drilling operations. It printed a named rig, an IMO number and an MMSI. It printed a fourteen-name support spread. It printed a start date already in force. It printed a 28 January 2027 kill. It printed four corners. It printed a 10 MN receipt. It printed an express cancel of 0122/26. It did not print a wreck buoy, a least depth, a fishing or anchoring prohibition, a restricted-in-ability-to-manoeuvre line, a VHF channel, a flag, a daily-hours clause, a weather window, or a port closure. Do not invent a 500-metre halo. That berth belongs to official 0137/26 Neptun Alpha, not to this rig. Do not invent a 2 NM cable berth. That figure belongs to dedicated 1411/26 Abeille Marengo. 0170/26 already prints the receipt: 10 MN. Hold MN on the official line; brief it as 10 nautical miles. Do not tidy YESLKOY into Yesilkoy or into 0122/26’s YESILKOV on the official line. Official English on this body keeps YESLKOY. Do not tidy MURRUVET ILHAN into Mürrüvet İlhan on the official line.
The geometry is the first briefing fact. The four corners sit around 43-03.5N 031-37.4E, a compact rectangle on the order of 2.4 nautical miles north–south by about 3.9 nautical miles east–west, not a circular exclusion of the southern Black Sea, not a TSS amendment, and not dedicated 0169/26’s Central Mediterranean dotted line. The box sits on the order of 85 nautical miles off the north Turkish coast near Amasra, well outside 12 nautical miles, in water that a passage plan already treats as a Turkish-EEZ drilling watch. The 10-nautical-mile receipt around that small box is the operational halo, not the four corners themselves. Do not brief a Zonguldak, Amasra, Ereğli or Constanta port shutdown from a four-corner rig plot. Do not brief a Ukrainian-corridor rewrite. Plot the four corners. Plot the 10-nautical-mile receipt. Give the named rig and the named support spread a practical CPA. Do not pass between the rig and unmarked anchors, hose, or a supply run. Do not assume AIS will show every hull on the fourteen-name list.
The date line is the second briefing fact. Work is printed as between 9 November 2026 until 28 January 2027. Tuesday afternoon is 10 November. The window opened yesterday and runs more than eleven weeks. 0170/26 does not print daily hours. It does not print a night-only or daylight-only limit. It does not print a weather clause. A passage plan that treats 9 November as a one-day move has under-read a winter-into-January watch. A passage plan that drops the watch after weekly group 44 killed itself at 092359 UTC 9 November has applied dedicated 0168/26’s wrapper cancel to the wrong number. A passage plan that still carries 0122/26’s 272059 UTC 27 November kill has not booked the paragraph-2 cancel. 0170/26 is a named-hull radio alert. It lives until 282059 UTC 28 January 2027 unless a later NAVAREA III cancels or amends it. The coordinator board prints the same kill as 28/01/2027 20:55. Hold 282059 on the English line.
The identification line is the third briefing fact. The coordinator named the hull, the IMO number and the MMSI. Abdulhamid Han. IMO 9705093. MMSI 271050408. That is the same pair dedicated 0168/26 still quoted against 0122/26 on 3 November. The move is the box, the dates and the support list, not a second rig. 0170/26 is not a flag print. It is not a call-sign print. It is not a restricted-manoeuvre print. Do not promote a Turkish flag, a drillship class or a water-depth rating onto the numbered text. The support spread is printed: Altan, Korkut, Murruvet Ilhan, Mihrimah, Osman Bey, Orhan Bey, Ertugrul Bey, Aybuke, Sancar, PSV Yeslkoy, PSV Florya, Menderes, Zorlu and Polatkan. Several of those names already sat on 0122/26. Altan, Korkut, Sancar, Zorlu, Polatkan and the PSV prefix on Yeslkoy and Florya are new on this body. Do not invent IMO numbers, MMSIs or flags for the support list. Do not drop a name because it also appears on official 0160/26 Yavuz or official 0132/26 Fatih. Shared support hulls are a Black Sea pattern, not a merger of three rigs onto one plot.
Industry-reprint colour, held separately: SeaLagom first carried the English body with an issued stamp of 8 November 00:00 UTC and a last-modified stamp of 9 November 13:00 UTC, matching Tuesday morning’s unused-primary note that the English text was retrieved on the 03:30 UTC desk. The Spanish coordinator page now lists 0170/26 as PLATAFORMA ABDULHAMID HAN, Mar Negro, cancel 28/01/2027 20:55, above dedicated 0169/26 and official 0160/26, and no longer lists 0122/26. Samsun NAVTEX 1099/26, Amasra 7/10 drilling, 9 November to 28 January, 10 miles from the working vessels, remains wrap on this file. Do not promote Amasra 7, Amasra 10, or a Turkish-language field name onto 0170/26. 0170/26 printed Abdulhamid Han, four corners and a 10 MN receipt. That is the product. Weekly group 45, official 0172/26, now sits on the same coordinator board with a cancel of 16/11/2026 23:59. Hold 0172/26 as the current weekly wrapper, unused as dedicated. Do not wait for a later English reprint of group 45 before plotting 43 02.34N 031 34.81E.
What this is not
This is not a rewrite of dedicated NAVAREA III 0122/26, and it is not a second live Abdulhamid Han box. 0122/26 was the summer-into-November watch: Black Sea drilling by Abdulhamid Han rig, IMO 9705093, MMSI 271050408, 19 August until 27 November 2026, four corners 43 05.03N 031 36.52E / 43 05.03N 031 39.95E / 43 02.63N 031 39.95E / 43 02.63N 031 36.52E, 10 MN receipt requested, cancel 272059 UTC 27 November 2026, cancelling 0114/26. Dedicated 0168/26, weekly group 44, still quoted that 0122 box as in force at 030600 UTC 3 November. Paragraph 2 of 0170/26 now cancels 0122/26. The new corners sit slightly south and slightly west of the old rectangle. The new kill is 28 January 2027, not 27 November 2026. A DPA who briefs Tuesday afternoon as “Abdulhamid Han still dies on 27 November” has kept 0122/26 after its own successor cancelled it. A DPA who briefs it as “the same four corners under a new serial” has not replotted 43 02.34N 031 34.81E. Replace 0122/26. Do not carry both as live. Do not restore 0122/26 because weekly group 44 still named it on 3 November. Group 44 killed itself at 092359 UTC 9 November.
This is not a rewrite of dedicated NAVAREA III 0169/26, and it is not Britoil Centurion moved into the Black Sea. Monday 4 November’s dedicated piece remains: CENTRAL MEDITERRANEAN SEA, oceanographic work on the Britoil Centurion, IMO 9619177 / MMSI 566921000, days 5 November 2026 to 15 February 2027, dotted-line groups A and B, wide receipt requested. 0169/26 prints a different hull, a different sea, a dotted line rather than a four-corner box, and a 15 February end. 0170/26 prints Abdulhamid Han, the Black Sea, four corners around 43-03N 031-37E, and a 28 January kill. Do not apply 0169/26’s 15 February date to this rig. Do not apply 0170/26’s 10 MN receipt to the Britoil Centurion track.
This is not dedicated 0168/26, and it is not weekly group 45 written as a dedicated drilling piece. Tuesday 4 November’s dedicated 0168/26 remains weekly group 44, in force 030600 UTC 3 November, cancel 092359 UTC 9 November, 2026 list 0036, 0086, 0122, 0132, 0137, 0160, 0168. That wrapper is now past. Official 0172/26, NAVAREAS III EN VIGOR, GRUPO SEMANAL 45, cancel 16/11/2026 23:59, is the later weekly list on the coordinator board this run, unused as dedicated. 0170/26 is a named-hull radio alert, not a catalogue. Masters who treat “not yet a dedicated group-45 article” as “0170 is not in force” have under-read a coordinator page that already lists 0170 above 0169 and no longer lists 0122. Pull the full text from the Spanish Hydrographic Institute NAVAREA page if the 1200 UTC SafetyNet broadcast is missed. Do not wait for a later English reprint of 0172/26 before the bridge plots the new corners.
This is not Yavuz, not Fatih, not Neptun Alpha, and not Key Manhattan. Official 0160/26 remains Black Sea drilling by Yavuz platform, IMO 9503768, MMSI 271046765, 20 October 2026 to 3 January 2027, four corners around 42-50N 031-10E, 10 nautical miles receipt required, cancel 032059 UTC 3 January 2027. Official 0132/26 remains Black Sea drilling by Fatih platform, IMO 9503770, MMSI 271046008, 4 September 2026 to 23 March 2027, four corners around 42-09N 030-12E, 10 nautical miles berth requested, cancel 232359 UTC 23 March 2027. Official 0137/26 remains Neptun Alpha production platform established at 44-02.85N 030-35.25E, maintain a safe distance of 500 metres. Official 0086/26 remains Adriatic drilling by Key Manhattan at 44-05.12N 013-45.27E through 202359 UTC 20 November. 0170/26 prints none of those IMO numbers and none of those boxes. A DPA who briefs Tuesday afternoon as “NAVAREA III has moved Yavuz north onto 43-03N” has borrowed 0160/26’s name and dropped Abdulhamid Han. Keep those numbers on their own lines. Three named Turkish-EEZ drilling watches can sit on the same Black Sea passage. They are not one watch.
This is not Saturday afternoon’s dedicated Irakleio 1411/26, and it is not Abeille Marengo. Saturday afternoon’s dedicated piece remains: EAST CRETAN SEA / SOUTHEAST CRETAN SEA / EAST MEDITERRANEAN SEA, research operation for underwater cable installation by ‘ABEILLE MARENGO’ from 6 November 2026 until 6 March 2027, 21-point line, wide berth requested 2 NM, cancel 062200 UTC 6 March 2027. NAVAREA III 0171/26 remains wrap on that file: coordinator listing cable operations by Abeille Marengo, IMO 9388613, eastern Mediterranean, cancel 6 March 2027 22:00, unused as a second dedicated hull piece until the English body is treated as a later primary. Official Cyprus 345/26 remains unused as dedicated. 0170/26 names neither Abeille Marengo nor a cable track. A Black Sea rig box is not a four-month east-Med cable. Do not collapse them because both now sit on the same coordinator board.
This is not this morning’s dedicated NAVWARN 1366/26, not last night’s dedicated 434/26, and not this morning’s dedicated IMO 131-count. This morning’s dedicated 1366/26 remains the Elefsina / Skaragka parachute disc, 10 and 11 November, 0600Z–1200Z, 1 nautical mile around 38 01 00N 023 34 00E. Last night’s dedicated 434/26 remains the Northern Gulf / Kuwait bathymetric survey on six named hulls. This morning’s dedicated IMO file remains 131 confirmed / 25 dead as at 9 November, HUDA top row. A Black Sea drilling relocation does not belong on that tape. Dedicated 815/26 remains the 10 November Kaliakra four-hour box, 100800–101200 UTC, which is now in its last printed hour as this desk files. Dedicated 799/26 remains Varna port and road, 0500–0900 UTC this morning now past, 0800–1200 UTC 13 November still ahead. Do not merge a Turkish-EEZ rig watch onto a Bulgarian harbour serial.
Operational implications
For a master already shaping a Turkish northern-coast, Amasra, Zonguldak, Ereğli, Constanta–Batumi or Istanbul–Novorossiysk passage between 9 November and 28 January, Tuesday afternoon is a CPA and lookout problem before it is a security rewrite. The coordinator named the hull, cancelled the summer box, printed four new corners and asked for a 10-nautical-mile receipt. A 10-nautical-mile receipt around a compact ~2.4-by-3.9-nautical-mile rectangle is a collision and supply-run problem, not a basin closure. It is not AIS-optional for the named rig. It is not 0160/26’s Yavuz box. It is not 0132/26’s Fatih box. It is not 0137/26’s 500-metre Neptun Alpha berth. A passage plan that only budgeted 0122/26’s 43 05.03N 031 36.52E corners, or that treated the southern Black Sea as clean after 0122/26’s 27 November kill, has not budgeted a later rectangle that opened yesterday and runs into January. Give the four corners. Give the 10-nautical-mile receipt. Give the fourteen-name support spread a practical berth. Do not pass between the rig and unmarked gear. Do not assume night work is off because hours were not printed.
The cancel of 0122/26 is the operational content a DPA has to get right. 0122/26 is no longer the live Abdulhamid Han instrument. 0170/26 is. Passage plans, ECDIS user charts and company SMS entries that still show 43 05.03N 031 36.52E as the working box, or that still show 272059 UTC 27 November as the kill, are stale as of paragraph 2. The move is small on a basin scale and large on a 10-nautical-mile CPA scale. The new south-west corner at 43 02.34N 031 34.81E sits west of the old west wall. A hull that used to scrape the old 10-nautical-mile halo on a westing may now owe a wider westing, or a southing, depending on the next port. Do not invent a port closure at Amasra, Zonguldak, Constanta or Midia. 0170/26 does not print a harbour-master sentence. Hulls that would otherwise have cut 43-03N 031-37E inside 10 nautical miles need an offset. Logging 0170/26 is not a substitute for a sighting report of the rig, a dark support hull, or a close-quarters situation. Those reports go to the coastal authority that owns the water — MSRCC Ankara / the relevant Turkish MRCC, or MRCC Constanta if the passage is the western face — and to the company security officer.
The Black Sea rig tape is three live 10-nautical-mile watches plus a 500-metre platform, not one. Yavuz still drills through 3 January 2027 around 42-50N 031-10E. Fatih still drills through 23 March 2027 around 42-09N 030-12E. Abdulhamid Han now drills through 28 January 2027 around 43-03N 031-37E. Neptun Alpha still sits at 44-02.85N 030-35.25E with a 500-metre berth. Key Manhattan still drills in the Adriatic through 20 November. Sea Guardian still asks for voluntary Mediterranean reporting. Charterers asking whether “NAVAREA III has gone quiet after group 44 dropped 0122/26 off the 3 November list” will not be answered by this file. What arrived is a later Abdulhamid Han box, not a Black Sea all-clear and not a mine-series rewrite. Official 0124/22, 0122/22 and 0092/22 remain the standing war-risk and mine cards on the coordinator board. 0170/26 does not cancel them.
Keep the dedicated files on their own lines. Dedicated 0169/26 remains Britoil Centurion, Central Mediterranean, through 15 February 2027. Dedicated 0168/26 remains weekly group 44, now past 092359 UTC 9 November. Official 0172/26 remains weekly group 45, unused as dedicated. Dedicated 1411/26 remains Abeille Marengo, 2 NM, through 6 March 2027; 0171/26 remains wrap. Official Cyprus 345/26 remains unused as dedicated. This morning’s dedicated 1366/26 remains the Elefsina parachute disc through 1200Z 11 November. Last night’s dedicated 434/26 remains the Kuwait bathymetric survey. Last night’s dedicated 815/26 remains Kaliakra, 100800–101200 UTC today. This morning’s dedicated IMO file remains 131 / 25 as at 9 November, HUDA top row. UKMTO still ends at dedicated 200-26. NAVAREA IX still lists dedicated 434/26 as the first row atop unused 433/26. Do not recast 10 November afternoon as a Black Sea exclusion zone, as a 0122 reprint, as a Yavuz conversion, or as a completed group-45 dedicated piece.
What Operators Should Note
- Log 0170/26 as the live Abdulhamid Han box, not as a 0122/26 reprint and not as a weekly-list rewrite. Official NAVAREA III 0170/26. Black Sea. Drilling operations by Abdulhamid Han rig, IMO 9705093, MMSI 271050408, supported by Altan, Korkut, Murruvet Ilhan, Mihrimah, Osman Bey, Orhan Bey, Ertugrul Bey, Aybuke, Sancar, PSV Yeslkoy, PSV Florya, Menderes, Zorlu and Polatkan. Between 9 November 2026 until 28 January 2027. Four corners 43 02.34N-031 34.81E / 43 04.72N-031 34.75E / 43 04.78N-031 39.98E / 43 02.40N-031 40.03E. 10 MN receipt requested. Cancel 282059 January 2027. Paragraph 2 cancels 0122/26. The warning names neither flag, VHF, RAM status, fishing ban, daily hours nor a port closure. Hold YESLKOY. Tuesday morning held this English body as unused as dedicated. Tuesday afternoon is the dedicated conversion. This is not 0169/26, not 0168/26, and not 0122/26 kept alive.
- Replot the four corners; drop 0122/26. The old 0122/26 rectangle was 43 05.03N 031 36.52E / 43 05.03N 031 39.95E / 43 02.63N 031 39.95E / 43 02.63N 031 36.52E, kill 272059 UTC 27 November. The new box sits slightly south and west. Compact ~2.4 × 3.9 NM rectangle around 43-03.5N 031-37.4E, on the order of 85 NM off Amasra. The 10-nautical-mile receipt is the working halo, not a basin closure. Do not brief Zonguldak, Amasra, Ereğli, Constanta or Midia as closed. Do not restore 0122/26 because dedicated 0168/26 still named it on 3 November.
- Hold 9 November to 28 January; do not keep the 27 November kill. Work opened yesterday, 9 November, and runs through 282059 UTC 28 January 2027. Coordinator board: 28/01/2027 20:55. No daily hours are printed. Do not apply dedicated 0168/26’s 092359 UTC 9 November wrapper cancel to this number. Do not apply 0122/26’s 272059 UTC 27 November kill to this number. Do not treat 9 November as a one-day move. Watch a later NAVAREA III that moves a corner, amends 09 Nov–28 Jan / 10 MN / 282059 Jan 27, adds a radius inside the 10 MN receipt, prints RAM language, or cancels 0170 before 28 January.
- Do not promote Samsun 1099/26 or weekly group 45 onto the NAVAREA. Samsun NAVTEX 1099/26 reprints Amasra 7/10 drilling, 9 November–28 January, 10 miles from the working vessels, on the same hull. That is wrap. 0170/26 remains Abdulhamid Han, four corners, 10 MN receipt. Use 1099/26 to confirm the dates and the 10-mile figure, not to add field names to the numbered NAVAREA. Official 0172/26, weekly group 45, cancel 16 November 2026 23:59, remains unused as dedicated. Dedicated 0168/26, weekly group 44, is past 092359 UTC 9 November. 0170 is a named-hull alert. It belongs on SafetyNet / SafetyCast. Pull the full text from the Spanish Hydrographic Institute page if the broadcast is missed.
- Keep the other Black Sea and Mediterranean rig watches on their own sheets. Official 0160/26 remains Yavuz, IMO 9503768, four corners around 42-50N 031-10E, 10 NM, through 032059 UTC 3 January 2027. Official 0132/26 remains Fatih, IMO 9503770, four corners around 42-09N 030-12E, 10 NM, through 232359 UTC 23 March 2027. Official 0137/26 remains Neptun Alpha at 44-02.85N 030-35.25E, 500 m. Official 0086/26 remains Key Manhattan through 202359 UTC 20 November. Dedicated 0169/26 remains Britoil Centurion through 15 February 2027. Do not merge those IMO numbers onto 0170/26. Shared support names are not a product merger.
- Keep the Greek, Bulgarian and Hormuz tape on their own sheets. This morning’s dedicated 1366/26 remains Elefsina / Skaragka, 10 and 11 November, 0600Z–1200Z, 1 NM around 38 01 00N 023 34 00E. Dedicated 1411/26 remains Abeille Marengo, 2 NM, through 6 March 2027; 0171/26 remains wrap; official Cyprus 345/26 remains unused as dedicated. Dedicated 815/26 remains Kaliakra, 100800–101200 UTC today. Dedicated 799/26 remains Varna port and road, 13 November 0800–1200 UTC still ahead. Dedicated 813/26 remains the 12 November Galata boarding box. Last night’s dedicated 434/26 remains the Kuwait bathymetric survey. This morning’s dedicated IMO file remains 131 / 25 as at 9 November, HUDA. UKMTO still ends at 200-26. NAVAREA IX still lists dedicated 434/26 atop unused 433/26. No UKMTO 201-26, no Update 113, no IMO 132, no ARN 169, no 435/26 and no official NAVWARN 818 this run. Sightings of the rig, a dark support hull, or a close-quarters situation go to the coastal authority that owns the water and to the CSO.
Regulas Shipping will keep lining NAVAREA III 0170/26 against dedicated 0122/26 so operators can treat Tuesday afternoon’s tape as a relocated Abdulhamid Han drilling watch from 9 November to 28 January, not as a 27 November reprint, a Yavuz conversion, or a Black Sea exclusion zone.
