Bulgaria’s Navy Hydrographic Service, now carrying the English text on its in-force NAVWARN board and on the Varna Radio / VTMIS warning page, prints NAVWARN 775/26 as a coast-wide reporting instrument, not as a wreck rewrite. The working primary is: NAVWARN 775/26 BULGARIA. BLACK SEA. TO ALL SHIPS PLANNING NAVIGATION THROUGH BULGARIAN TERRITORIAL SEA, 2 HOURS BEFORE ENTERING TERRITORIAL SEA, FOLLOWING INFORMATION TO BE SEND ON E-MAIL [email protected]: SP A — NAME, IMO NUMBER, FLAG, CALL SIGN OR SHIP STATION IDENTITY; H+C — ENTRY POINT INTO BULGARIAN TERRITORIAL WATERS, a 6-digit group giving the event day of the month (first 2 digits) and hours and minutes in UTC (next 4 digits), a 4-digit group giving latitude in degrees and minutes suffixed N or S and a 5-digit group giving longitude in degrees and minutes suffixed E or W; G — NAME OF LAST PORT OF CALL; I — NAME OF NEXT PORT OF CALL; P — CARGO AND BRIEF DETAILS OF DANGEROUS CARGOES AS WELL AS HARMFUL SUBSTANCES AND GASES THAT COULD ENDANGER PERSONS OR THE ENVIRONMENT; W — NUMBER OF PERSONS ON BOARD, INCL. MASTER; X — REMARKS, INCL.: X1. FUEL (TYPE AND QUANTITY), LUBOIL; X2. ANY DEFICIENCIES/MALFUNCTIONS ON BOARD; X3. ISM MANAGER (E-MAIL AND GSM); X4. OTHER. That is the product. It names a mailbox, it names a two-hour lead, and it names an IMO Standard-format field list. It does not name a wreck, a keep-clear radius, a port closure, or a new weapon clock.
That is the first fresh Black Sea reporting instrument after Thursday’s dedicated Contship Jet sinking and Khoryv keep-clear. Thursday afternoon’s dedicated NAVWARN 768/26 piece on this desk recorded Contship Jet, IMO 9348625, sunk in 43-07.80N 028-45.36E with more than 20 dangerous-goods containers adrift. Thursday morning’s dedicated 766/26 remains the five-cable keep-clear on Khoryv, IMO 8138712, at 43-30.60N 028-43.69E. 775/26 sits on the same in-force board, above those wrecks. It is not a second drone attack. It is not a rewrite of 768/26 or 766/26. Masters who brief Saturday as a Varna or Burgas harbour shutdown, as a completed container recovery, as a new Kaliakra wreck, or as Warning 189-26 will have merged a pre-entry email into four other series.
What the warning actually printed
The hydrographic text is short and is the working primary. NAVWARN 775/26. Bulgaria. Black Sea. To all ships planning navigation through Bulgarian territorial sea. Two hours before entering territorial sea, send the listed information on e-mail [email protected]. The field list is the IMO Standard reporting format in coastal clothing: SP A for identity; H+C for the territorial-sea entry point with a 6-digit UTC day-hour-minute group and a lat/long group; G last port; I next port; P cargo and dangerous goods; W persons on board including the master; X remarks with four named sub-lines for fuel and luboil, deficiencies, the ISM manager’s e-mail and GSM, and other. Stay with that wording. Do not invent a VHF-only alternative. 775/26 prints an e-mail. Do not invent a 24-hour or 48-hour lead. The notice prints two hours. Do not invent a fee, a permit number, or a daylight-only window. The notice does not print those either.
The mailbox is the first briefing fact. The working address is [email protected]. That is the Bulgarian Vessel Traffic Management Information System reporting desk, not UKMTO, not NAVCENT NCAGS, and not MSCIO. A DPA who briefs Saturday as “we already report to UKMTO, so the Bulgarian mail is optional” has treated a coastal-state territorial-sea notice as a voluntary security product. 775/26 is addressed to all ships planning navigation through Bulgarian territorial sea. Innocent passage, a Varna or Burgas call, a Constanta-bound track that clips the 12-mile belt, and a northbound run past Kaliakra and Shabla all sit inside that sentence. The notice does not carve out warships, yachts, or ships in innocent passage.
The two-hour clock is the second briefing fact. The mail has to leave the ship two hours before the territorial-sea line, not two hours before a pilot, not two hours before a berth, and not two hours after the master decides to come in. The H+C group is the entry event: day of the month, UTC time, and the lat/long of the crossing. A passage plan that only carried Thursday’s wreck plots, or that treated the Bulgarian coast as a lookout problem because 768/26 still prints no radius, has not budgeted a written identity-and-cargo dump before the 12-mile line. SeaLagom’s coastal board, industry colour of public availability only, first carried 775/26 at 1207 UTC 30 October and marked it PAN PAN; the official hydrographic English archive is the working text. Do not treat 1207 UTC as a start-of-enforcement clock that the NAVWARN itself does not print.
The field list is the third briefing fact. A is name, IMO, flag and call sign or ship-station identity. H+C is the crossing. G and I are last and next port by name. P is cargo plus dangerous goods, harmful substances and gases that could endanger persons or the environment. W is persons on board, master included. X1 is fuel type and quantity and luboil. X2 is any deficiency or malfunction. X3 is the ISM manager’s e-mail and GSM. X4 is other. That is a pre-arrival pack, not a wreck report. It is also a deficiency and ISM-contact pack. A master who sends only the ship’s name and IMO has not met the notice. A master who omits X2 because “nothing is wrong” has still to say so. A master who leaves X3 blank has left the company security and ISM contact off a coastal-state file that already sits next to two wrecks.
Same-board instruments, not second primaries, remain in force around this mail. NAVWARN 768/26 remains the working Contship Jet wreck-and-cargo instrument, 43-07.80N 028-45.36E, extreme caution, over 20 containers including flammable gases, non-flammable non-toxic gases, flammable liquids and other dangerous goods. NAVWARN 766/26 remains the Khoryv five-cable keep-clear, 43-30.60N 028-43.69E, capsized, semi-submerged, drifting, without crew and lights. NAVWARN 776/26, issued the same 30 October clock, closes a diving-exercise box south of Cape Galata from 030600 UTC to 051430 UTC 3–5 November: 43-04.765N 027-54.949E, 43-04.767N 027-55.055E, 43-04.120N 027-55.807E, 43-04.120N 027-55.056E; navigation, anchoring, fishing, diving and underwater activities prohibited. NAVWARN 777/26 puts hydrographic cutter 331 in Burgas Bay from 030615 UTC to 061600 UTC 3–6 November, mariners to keep a minimum 3 cables. NAVWARN 757/26 remains the Varna Lake BRIZ-ESEN 2026 regatta prohibition, including 310900–311700 UTC today and 010800–011600 UTC 1 November. None of those numbers is 775/26. Do not merge a Galata diving box or a lake regatta into a coast-wide e-mail.
What this is not
This is not a rewrite of Contship Jet. Thursday afternoon’s dedicated NAVWARN 768/26 remains the working wreck: M/V CONTSHIP JET, IMO 9348625, sunk at 282030 UTC 28 October in 43-07.80N 028-45.36E, over 20 dangerous-goods containers adrift, extreme caution, no radius, no wreck buoy, no least depth. 775/26 does not reprint that plot. It does not cancel it. A DPA who briefs Saturday as “the wreck mail” has invented a wreck-reporting form that the notice does not print. Sightings of the wreck, of containers, of pollution or of persons in the water still belong with the coastal-state MRCC and with the company security officer. They are not a substitute for the two-hour SP mail, and the SP mail is not a substitute for them.
This is not a rewrite of Khoryv. Thursday morning’s dedicated NAVWARN 766/26 remains the working five-cable keep-clear east of Shabla: 43-30.60N 028-43.69E, IMO 8138712, capsized, semi-submerged, drifting, without crew and lights. Friday’s dedicated Romanian Naval Authority file remains the Khoryv casualty and search piece. Tuesday’s dedicated ARN 158/2026 remains the last Romanian wreck-move and is no longer the working keep-clear. 775/26 does not move 43-30.60N 028-43.69E. It does not apply a five-cable circle to every territorial-sea entry. Do not collapse the two wrecks into the e-mail, and do not apply Khoryv’s radius to a ship that has only failed to send the mail.
This is not Warning 189-26, and it is not a Hormuz product. This morning’s companion UKMTO Attack is a time-late 28 October crude-oil-tanker projectile on an outbound Hormuz transit. It does not name a Bulgarian mailbox. NAVAREA IX still ends, on the Pakistan Saturday table, at 423/26 as an in-force list and at 422/26 as a southern-Gulf dhow sailing race; 420/26 remains last night’s dedicated RITI fire-and-anchor. This is not Update 110. Update 109, JMIC# 001 26, ICOD 291300 UTC 29 October, remains the last numbered public periodic note. This is not an International Maritime Organization 122-count. The highlighted-incidents board is still 121 confirmed / 24 seafarer fatalities as at 27 October, with Leonora Kosan still the newest named Middle East row. Contship Jet and Khoryv do not belong on that table. 775/26 does not put them there.
This is not a Varna, Burgas, Constanta, Midia, Mangalia or Sulina closure. 775/26 requires a mail. It does not prohibit entry. It does not print a traffic-separation change. It does not print an armed-boarding warning. Same-board 776/26 and 777/26 are 3–6 November exercise and survey boxes, not this weekend’s territorial-sea line. 757/26 is a Varna Lake regatta, not a Black Sea coastal closure. Do not merge a harbour-training circle or a lake prohibition into a 12-mile reporting notice. 775/26 is a pre-entry identity, cargo, fuel, deficiency and ISM-contact watch. It is not a shoreline-pollution confirmation and not a completed container recovery.
This is not Wine Trader at 45-00.40N 029-59.92E, not HS Dignity, not Chelsea 3, not MApN 213, not the EP 432-52-88 / CSAT vote, and not Tuesday’s NATO extra-MPA note. Open-register colour on the two wrecks is unchanged from Thursday’s dedicated files and stays colour here. None of that listing colour sits on 775/26. Do not promote it to a NAVWARN fact.
Operational implications
For a master shaping Constanta, Midia, Mangalia, Varna or Burgas this weekend, Thursday’s two wreck plots are still on the board and a coast-wide e-mail now sits in front of them. 768/26 still puts a sunk containership at 43-07.80N 028-45.36E with an unlocated dangerous-goods box field. 766/26 still puts a five-cable keep-clear on Khoryv at 43-30.60N 028-43.69E. 775/26 now requires the ship to identify itself, its flag, its last and next port, its cargo and dangerous goods, its people, its fuel, its defects and its ISM manager two hours before the territorial-sea line. A passage plan that only carried the Kaliakra and Shabla offsets, or that treated the Bulgarian coast as a lookout-and-CPA problem because 768/26 still prints no radius, has not budgeted a written pack to [email protected]. The 12-mile belt off Kaliakra and Shabla is exactly the water in which those wrecks sit. Innocent passage still has to send the mail.
For a DPA and an operator with feeders or general cargo on Haifa–Constanta, Piraeus–Varna or any west-Black-Sea rotation this week, the reporting split is the operational content. The two-hour SP mail goes to [email protected]. Further sightings of Contship Jet, of Khoryv, of containers, of pollution or of persons in the water belong with the coastal-state MRCC and with the company security officer, not with UKMTO 189-26. 775/26 does not order an armed team, a daylight-only transit, or a deviation around a published circle. It also does not authorise a master to treat the mail as optional because the ship is only clipping territorial sea on a Constanta track. Log the warning number, the two-hour lead, the mailbox, the SP A / H+C / G / I / P / W / X field list, and the fact that 768/26 and 766/26 remain the working wreck instruments. Do not log a harbour closure, a wreck buoy, or a completed recovery that 775/26 does not print.
The X lines are the practical compliance watch, not a completed all-clear. X1 wants fuel type and quantity and luboil, not a “bunkers normal” shrug. X2 wants defects and malfunctions named. X3 wants the ISM manager on e-mail and GSM, which is a company-security contact sitting on a coastal-state file next to two wrecks. Next-port authorities in Varna, Burgas and Constanta will now ask whether the ship sent the mail, whether the H+C group matched the actual crossing, and whether X2 and X3 were filled. Charterers and P&I will ask the same questions when a ship is delayed, boarded, or asked to stand off. They will not be answered by 768/26’s extreme-caution line, by 189-26, by 016-26, or by Tuesday’s 121-count.
Same-board 776/26 and 777/26 are next week’s coastal boxes, not this morning’s mail. From 3 November a diving-exercise prohibition sits south of Cape Galata, on the Varna approach, and cutter 331 works Burgas Bay with a 3-cable berth. Those numbers belong in the 3–6 November night orders. They do not replace 775/26, and 775/26 does not replace them. 757/26 still closes a Varna Lake box through this afternoon and again on 1 November; that is a lake regatta, not a substitute territorial-sea report.
Keep the dedicated files on their own lines. 768/26 remains Thursday afternoon’s dedicated Contship Jet wreck-and-cargo piece and is still in force. 766/26 remains Thursday morning’s dedicated Khoryv five-cable keep-clear and is still in force. 759/26 remains Thursday morning’s dedicated surface-drone-hit piece and is no longer the working caution. Friday’s ANR Khoryv naming remains the casualty/search piece. Wine Trader remains the dedicated Sulina fire. 189-26 is this morning’s companion Hormuz time-late Attack. 188-26 remains last night’s Lavan Island Attack. 187-26 remains Friday morning’s Khasab attached-device Attack. 420/26 remains last night’s dedicated RITI fire-and-anchor. Update 109 remains the last periodic Middle East threat note. 016-26 remains Wednesday afternoon’s blockade document pack. Do not recast 31 October morning as a second Contship attack, as an IMO 122-count, as a Varna closure, as Warning 189-26, or as a completed salvage.
What Operators Should Note
- Log 775/26 as a two-hour territorial-sea e-mail, not as a wreck rewrite. NAVWARN 775/26, 30 October 2026. Bulgaria, Black Sea. All ships planning navigation through Bulgarian territorial sea. Two hours before entry, e-mail [email protected]. Fields: SP A name / IMO / flag / call sign or ship-station identity; H+C entry point with 6-digit UTC day-hour-minute and lat/long; G last port; I next port; P cargo and dangerous goods, harmful substances and gases; W persons on board including the master; X1 fuel type and quantity and luboil; X2 deficiencies or malfunctions; X3 ISM manager e-mail and GSM; X4 other. No wreck plot, no radius, no port closure on this notice. This is not 768/26, not 766/26, not 189-26, and not a harbour shutdown.
- Send the mail before the 12-mile line, not before the pilot. The two-hour lead is to territorial-sea entry. Innocent passage, a Varna or Burgas call, and a Constanta-bound track that clips the belt all sit inside the notice. The working mailbox is [email protected]. UKMTO, NAVCENT NCAGS and MSCIO are different desks. Registering with one of them is not a substitute for this mail.
- Fill every SP line, including X2 and X3. A name-and-IMO only message does not meet the notice. H+C needs the UTC day-hour-minute group and the crossing lat/long. P needs dangerous goods and harmful substances named, not “general cargo” if the ship is carrying classed boxes. W includes the master. X1 is fuel and luboil by type and quantity. X2 is defects. X3 is the ISM manager on e-mail and GSM. Leave those blank and the coastal-state file is incomplete next to two wrecks.
- Do not merge this mail onto Contship Jet, Khoryv or Hormuz. 768/26 remains in force: Contship Jet, IMO 9348625, 43-07.80N 028-45.36E, over 20 dangerous-goods containers, extreme caution, no radius. 766/26 remains in force: Khoryv, IMO 8138712, 43-30.60N 028-43.69E, five-cable keep-clear. Sightings of those hulls still go to the MRCC, not to the SP mailbox as a substitute. 189-26 is a time-late Hormuz crude-oil-tanker Attack. Update 109 remains last periodic note. IMO still 121 / 24 as at 27 October. 016-26 remains the blockade document pack.
- Hold 776/26, 777/26 and 757/26 on their own lines. 776/26 closes a diving box south of Cape Galata from 030600 UTC to 051430 UTC 3–5 November. 777/26 puts cutter 331 in Burgas Bay from 030615 UTC to 061600 UTC 3–6 November with a 3-cable berth. 757/26 still prohibits a Varna Lake box through 311700 UTC today and again 010800–011600 UTC 1 November. None of those is the territorial-sea e-mail. Do not brief Saturday as a Varna or Burgas closure because a lake regatta and a next-week exercise sit on the same board.
- Treat a missed mail as an entry problem, not as a completed wreck recovery. 775/26 does not cancel 768/26 or 766/26. It does not mark a wreck buoy, a least depth, a pollution line or a salvage. Watch a later NAVWARN that moves those wrecks or that amends the mailbox; a later ministry note on the 18 or the 421; or a flag/class statement. Do not brief Saturday as a completed hull or cargo recovery because Bulgaria has asked for identity and cargo two hours out.
Regulas Shipping will keep lining NAVWARN 775/26 against Thursday’s dedicated 768/26 Contship Jet wreck and 766/26 Khoryv keep-clear so operators can treat Saturday’s product as a two-hour territorial-sea e-mail to [email protected], not as a second attack, a harbour closure, or a completed salvage.
