The Hydrographer of Pakistan issued NAVAREA IX 436/26 at 111030 UTC on 11 November as an Arabian Sea / Pakistan cable-repair warning. The official text, retrieved from the National Hydrographic Office product file 20261111SEC 436.txt, puts a cable repair operation to be conducted by CS MARAM from 11 November along a two-point line. The charts cited are PAK 5 (INT 7314), 33, 57 (INT 751) and BA 707. Mariners are requested to give wide berth. That is the working primary. It is a numbered cable-repair product on Pakistan Arabian Sea water. It is not a rewrite of last night’s dedicated 435/26 Fujairah jack-up on SKATE 3D, not a reprint of Monday night’s dedicated 434/26 Kuwait bathymetric survey, not a conversion of Friday morning’s dedicated 431/26 into a Karachi cable, and not a conversion of dedicated 1411/26 Abeille Marengo onto a Pakistan hull.
Pakistan’s NAVAREA IX in-force table, as of Wednesday 11 November, now opens with 436/26 as the first row: DTG 111030 UTC 11 November, region NAVAREA IX, description CABLE REPAIR OPERATION. Hold that table wording. The same Wednesday table still carries dedicated 435/26 as the second row, DTG 101500 UTC 10 November, Southern Gulf / UAE, GEOTECNICAL SURVEY OPERATION. Dedicated 434/26 remains the third row, DTG 091500 UTC 9 November, Northern Gulf / Kuwait, BATHYMETRIC SURVEY. 433/26 remains the unused self-cancelling in-force list. 432/26 remains Friday night’s dedicated Southern Gulf container, already past its 082359 UTC 8 November cancel; the Wednesday listing is stale. 431/26 remains Friday morning’s dedicated Fujairah geotechnical survey on SKATE 3D through 132359 UTC 13 November — still on the Wednesday table as a separate GEOTECNICAL SURVEY OPERATION row. Masters who brief Wednesday afternoon as a Hormuz Attack, as a Karachi port closure, as SKATE 3D moved to Pakistan, or as a second 1411/26 Abeille Marengo reprint will have merged a new two-point Arabian Sea cable line into either a security wreck, a Fujairah jack-up, or a Cretan cable track.
What 436/26 actually printed
The hydrographic text is short and is the working primary. DTG 111030 UTC NOV 2026. NAVAREA IX 436/26. ARABIAN SEA. PAKISTAN. CHARTS PAK 5 (INT 7314), 33, 57 (INT 751) AND BA 707. CABLE REPAIR OPERATION WILL BE CONDUCTED BY CS MARAM FROM 11 NOV 26 ALONG THE LINE JOINING FOLLOWING POINTS: START 24-43.60N 066-40.29E END 24-42.29N 066-34.75E. MARINERS ARE REQUESTED TO GIVE WIDE BERTH. Stay with that wording. The coordinator printed CS MARAM without quotation marks; hold that spelling. Do not tidy MARAM into Maram, MARAM I or CS MARAM 1 on the official line. The coordinator printed neither an IMO number, an MMSI, a flag, a call sign, a RAM status, a VHF working channel, a numeric berth in cables or nautical miles, a diving window, a guard-ship name, a port-closure sentence, a CANCEL THIS MSG DTG, nor an end date beyond FROM 11 NOV 26. Stay with the two points, CS MARAM, cable repair, wide berth, the four charts, and the 11 November start.
The geometry is the first briefing fact. The line runs from 24-43.60N 066-40.29E to 24-42.29N 066-34.75E — a compact track on the order of five nautical miles, west of Karachi / Port Muhammad Bin Qasim on PAK 5 / 33 / 57 and BA 707 water, not in the Strait of Hormuz, not in Fujairah harbour, and not in the East Cretan Sea. Plot the start and the end. Last night’s dedicated 435/26 remains a five-corner Port of Fujairah box around 25-09N 056-22.7E. Monday night’s dedicated 434/26 remains an eight-point Kuwait box around 29-01N 048-11E. Dedicated 1411/26 remains a 21-point Abeille Marengo cable track from 35-24.98N 024-56.13E to 34-09.68N 030-04.31E, 2 NM berth, through 062200 UTC 6 March 2027. Those are other coordinators and other water. A passage plan that files 436/26 as “the cable ship, same as Abeille Marengo” has put a Pakistan Arabian Sea repair on a Cretan research track. A passage plan that treats 24-43.60N 066-40.29E as a Fujairah jack-up has dropped the Arabian Sea / Pakistan header. Do not treat Karachi harbour as this line. Do not treat Port Qasim as closed. Do not run 11 November onward as if the Pakistan west-coast approaches were empty of cable plant.
The clock is the second briefing fact. 436/26 carries a 111030 UTC 11 November issue time and a printed start FROM 11 NOV 26. It does not print a CANCEL THIS MSG DTG. It does not print an until date. It does not print daily hours. That is an open-ended repair from today’s date, not a two-hour window and not a 20 November self-cancel. Dedicated 435/26 still kills itself at 202359 UTC 20 November. Dedicated 431/26 still kills itself at 132359 UTC 13 November. Dedicated 1411/26 still kills itself at 062200 UTC 6 March 2027. Dedicated 1404/26 still kills itself at 112200 UTC 11 November — that kill is this afternoon. A passage plan that treats 24-43.60N 066-40.29E as live only until dusk on 11 November has under-read a FROM 11 NOV 26 start with no printed kill. A passage plan that borrows 435/26’s 20 November cancel, 1411/26’s 6 March cancel, or 1404/26’s 112200 UTC cancel onto CS MARAM has put another product’s DTG on this line. Do not invent a 0800–1600 UTC working window. Do not invent a night suspension. Hold the repair as to be conducted from 11 November along the printed line until a later NAVAREA moves it or cancels it.
The chart list is the third briefing fact. 436/26 cites PAK 5 (INT 7314), 33, 57 (INT 751) and BA 707. Dedicated 435/26 cited BA 2837, 3520, 3709 and 3723. Dedicated 431/26 cited BA 2858, 3520 and 3526. Dedicated 434/26 cited BA 1223, 2884, 3773 and KU 1. No shared sheet with those Gulf products. Do not copy Tuesday’s Fujairah chart set onto Wednesday’s Pakistan notice. Do not drop PAK 5 or INT 7314 because a master already had BA 707 open for a Karachi approach. The coordinator issued a Pakistan chart set against a Pakistan two-point line. Plot that set.
The missing IMO, MMSI, flag, RAM, numeric-berth and CANCEL DTG lines are omissions, not a completed cable order. Do not invent Channel 16 as a repair working channel. Do not invent a 2 nautical mile halo; that figure belongs to dedicated 1411/26 and dedicated 1404/26, not to a notice that already says wide berth without a number. Do not borrow 434/26’s six Kuwait hulls, 435/26’s SKATE 3D, 411/26’s Qatar pipelay berth, or 1411/26’s Abeille Marengo onto a line that already names CS MARAM. Give the two points and the named cable ship. Do not promote an open-register IMO, MMSI or flag onto CS MARAM.
Same-board wrap, not this berth: 435/26 remains last night’s dedicated second Fujairah SKATE 3D box through 202359 UTC 20 November — still in force, not cancelled by 436/26. 434/26 remains Monday night’s dedicated six-hull Kuwait bathymetric survey. 433/26, 070300 UTC 7 November, INFORCE LIST, unused as dedicated. 432/26 remains Friday night’s dedicated Southern Gulf floating and partially submerged container at 25-09.71N 054-54.06E, cancel 082359 UTC 8 November — now past; the Wednesday NHO row is a stale listing, not a live 11 November caution. 431/26 remains Friday morning’s dedicated SKATE 3D geotechnical survey at Port of Fujairah through 132359 UTC 13 November — still in force. 428/26 remains unused Amaala Triple Bay seaplane wrap. 427/26 remains dedicated Shura Island seaplane zone. 425/26 remains the dedicated Selat Storm wreck. 414/26 remains the dedicated November Pakistan firing series through 302000 UTC 30 November. 397/26 remains the Port Muhammad Bin Qasim buoy-relaid caution. Those clocks are separate.
What this is not
This is not a rewrite of 435/26, and it is not SKATE 3D moved to Pakistan. Last night’s dedicated 435/26 remains a Port of Fujairah geotechnical survey by self-elevating platform ‘SKATE 3D’, five corners around 25-09N 056-22.7E, mariners cautioned, charts BA 2837, 3520, 3709 and 3723, cancel 202359 UTC 20 November. 436/26 names neither Fujairah nor SKATE 3D. 435/26 names neither CS MARAM nor 24-43.60N. A passage plan that drops the Fujairah box at 111030 UTC 11 November has deleted a still-in-force harbour product through 20 November. A passage plan that files Wednesday afternoon under “the top NHO row is still the jack-up” has ignored a new cable-repair number. Hold both numbers. Do not collapse 436/26 onto 435/26 as “the same survey, later date.”
This is not a rewrite of 431/26, and it is not the first Fujairah jack-up cancelled at 11 November. Friday morning’s dedicated 431/26 remains a Port of Fujairah geotechnical survey by SKATE 3D, four corners around 25-09.6N 056-22.5E, mariners cautioned, charts BA 2858, 3520 and 3526, cancel 132359 UTC 13 November. 436/26 does not name 431/26. It does not cancel 431/26. From this afternoon through 13 November the Wednesday table still carries 431/26 as a live GEOTECNICAL SURVEY OPERATION row beneath 436/26, 435/26 and 434/26. Do not kill the Friday box because a Pakistan cable ship is now the top NHO row.
This is not a rewrite of 434/26, and it is not the Kuwait survey moved east. Monday night’s dedicated 434/26 remains a Northern Gulf / Kuwait bathymetric survey by vessels ‘VISION 2, MOSAAID 01001, NAIA, KNOZE 7, SEP 2 AND AL-NOWKHADA ABOODAH’ in an eight-point box around 29-01N 048-11E, mariners cautioned, 378/26 cancelled, no printed kill against 434/26. 436/26 names neither Kuwait nor those six hulls. 434/26 names neither CS MARAM nor Pakistan. A passage plan that files Wednesday afternoon under “the Gulf survey” has put a Karachi-approaches cable ship on the Kuwait approaches. Keep 434/26 on its own Northern Gulf sheet.
This is not a rewrite of 1411/26, and it is not Abeille Marengo renamed. Dedicated Irakleio 1411/26 remains a 21-point underwater-cable research track by ‘ABEILLE MARENGO’ from 6 November through 6 March 2027, 2 NM berth, East Cretan Sea / southeast Cretan Sea / East Mediterranean, cancel 062200 UTC 6 March 2027. NAVAREA III 0171/26 remains wrap on that hull. Official Cyprus 345/26, VB ABEILLE MARENGO, geological survey in the Cyprus EEZ 19 November 2026–19 March 2027, remains unused as dedicated. 436/26 names CS MARAM, names a two-point Arabian Sea / Pakistan line, names wide berth without a number, and does not print a 2 NM halo or a March kill. A Cretan research track is not a Pakistan repair. Do not promote IMO 9388613, MMSI 228505700, FPEI, VB or a 6 March DTG onto 436/26. Do not collapse 436/26 onto dedicated 1404/26 as a Kobi Ruegg fiber-optic rewrite; 1404/26 remains the 2 NM southeast-Cretan track through 112200 UTC 11 November, unused as a Pakistan conversion.
This is not a rewrite of 433/26, and it is not a new in-force catalogue. 433/26 remains the 070300 UTC 7 November self-cancelling list of navigational warnings in force, unused as dedicated, ending the 2026 series at 427, 428, 431 AND 432. 436/26 is a new numbered repair issued after that list. Do not treat 433/26 as having already included 436. Do not treat 436/26 as a reprint of the catalogue. A later in-force list that adds 436 will be a later product.
This is not a rewrite of 414/26, and it is not a Pakistan firing box. 414/26 remains the dedicated November Arabian Sea / Pakistan live-weapon firing series through 302000 UTC 30 November. 436/26 names a cable ship, names a two-point repair line around 24-43N 066-37E, and requests wide berth. 414/26 does not name CS MARAM. 436/26 does not reprint 414/26’s firing boxes. A passage plan that drops the November firing series because a cable-repair number is now the top NHO row has deleted a still-in-force weapon product. A passage plan that treats 24-43.60N as a firing corner has converted a repair into a gunnery watch.
This is not a security-incident NAVAREA and not a wreck product. 425/26 remains the dedicated Selat Storm wreck. 420/26 remains the dedicated RITI fire-and-anchor. 417/26 remains the dedicated Quba wreck. 389/26 remains the Gulf of Oman oil-tanker security-incident caution. This morning’s dedicated IMO 133-count remains Navig8 Macallister on the highlighted-incidents board as at 10 November, 133 confirmed, 25 seafarer fatalities. Dedicated Update 112 remains the 8 November JMIC note. Dedicated 197-26, 198-26, 199-26, 200-26 and this morning’s dedicated 201-26 remain unnamed UKMTO tanker files. This afternoon’s companion Warning 202-26 remains a Suspicious Activity on a tanker in the Strait of Hormuz. 436/26 names none of those hulls, prints no projectile, and does not sit in the Strait of Hormuz. Do not brief Wednesday afternoon as a Hormuz Attack because a Pakistan cable ship is the new top NHO row.
This is not 411/26, and it is not a Qatar pipelay rewrite. 411/26 remains the dedicated McDermott DB30 subsea-pipeline berth in the central Gulf / Qatar. 436/26 is a Pakistan Arabian Sea cable repair, not a Qatar trench. This is also not NAVAREA III 0170/26 on Abdulhamid Han, not HNHS 1370/2026 on AEGAEO, not NAVAREA VIII 1169/26 on the Mumbai cable-repair cluster, and not last night’s dedicated Irakleio 1441/26 void of unauthorised FA76-1127-26. Those are drilling, research, cable and NAVTEX products on other coordinators. They do not belong on a 24-43N Pakistan watch.
This is not a Karachi, Port Qasim or Hormuz port closure, not a Gulf of Oman TSS change, and not a rewrite of 397/26’s Port Muhammad Bin Qasim buoy. 436/26 prints mariners requested to give wide berth along a two-point line. It does not close Karachi. It does not close Port Qasim. It does not reopen Hormuz. It does not cancel 435/26, 434/26, 431/26, 414/26 or 397/26. It is not a Houthi merchant-attack product. 436/26 prints a cable repair operation — not a strike, not a projectile, and not a keep-clear in nautical miles.
Operational implications
For a master inbound to Karachi or Port Muhammad Bin Qasim, shaping a Pakistan west-coast coastal transit, or crossing BA 707 / PAK 5 water west of 24-43N this week, 436/26 is an approaches-plot amendment before it is a construction story. The two points sit on a compact line on the order of five nautical miles, west of the Karachi / Port Qasim harbour faces, not inside the inner basins. The notice names the cable ship. It does not print a vertical limit, a lighting scheme, a VHF working channel, a named guard ship, a numeric berth, or a kill DTG. Wide berth is the whole instruction, with a start FROM 11 NOV 26 and no printed cancel. A passage plan that treats 24-43.60N 066-40.29E as a charted obstruction after a later cancel without reading the replacement NAVAREA has over-read a repair that still has no kill. A passage plan that only annotates “cable ship, Pakistan” without the two points, or that keeps only 1411/26’s 2 NM Cretan halo, has under-read a numbered NAVAREA that exists to be plotted.
The missing numeric berth is the first operational trap. Dedicated 1411/26 and dedicated 1404/26 print 2 NM. Dedicated 1370/2026 prints 0.2 N.M. 436/26 prints wide berth and does not print a number. A DPA who copies 2 NM onto CS MARAM has borrowed another coordinator’s figure. A DPA who treats wide berth as “no berth required” has under-read a cable-repair caution on a named hull. Plot the start and the end. Give the ship room. Do not invent 0.5 NM, 1 NM or 2 NM as if they were on the NHO file.
The overlap with 414/26 is the second Pakistan problem on the same coast. 414/26 remains the November live-weapon firing series through 302000 UTC 30 November. 436/26 is a cable-repair line from 11 November with no printed kill. They are not the same box. A pilot briefing that says “Pakistan west coast is the firing product” after 111030 UTC 11 November has not plotted Wednesday’s two-point repair. A DPA who kills the entire Pakistan watch at 30 November has dropped an open-ended CS MARAM line that 414/26 does not cancel. Hold 414/26 through its own 30 November cancel. Hold 436/26 until a later NAVAREA moves it. Do not invent a single merged Arabian Sea exclusion from the firing boxes through 24-43.60N. Plot the printed corners and the printed line.
For DPAs with Karachi, Port Qasim, Gwadar, Fujairah, Hormuz or Gulf of Oman stems this week, the operational question is whether the planned west-coast track clips the two-point list, not whether Pakistan “closed Karachi.” 436/26 does not close Karachi. It does not close Port Qasim. It does not reopen Hormuz. It does not cancel 435/26, 434/26, 431/26, 414/26 or 397/26. A fixture that only budgeted last night’s Fujairah jack-up, Monday night’s Kuwait survey, this morning’s IMO 133-count on Navig8 Macallister, or this afternoon’s companion Warning 202-26 has not budgeted a named cable ship on the Pakistan Arabian Sea plot from 11 November. 435/26 remains the second Fujairah SKATE 3D box through 20 November. 431/26 remains the first Fujairah SKATE 3D box through 13 November. 434/26 remains the Kuwait named-hull survey. Those clocks are separate.
The stale rows on this Wednesday’s NHO table are a second briefing trap. 432/26 is still printed as a floating or partially submerged container. That notice cancelled at 082359 UTC 8 November. Do not restore it because the Wednesday table still lists it. Do not treat 436/26 as the replacement for 432/26; a Pakistan cable ship does not cancel a Southern Gulf container. 433/26 is the 7 November in-force catalogue, unused as dedicated, and still ends the 2026 series at 432. Everything else on the Wednesday table is either a dedicated earlier file or a stale listing. 435/26 and 431/26 are not stale. They are still live through 20 November and 13 November respectively.
Dedicated 1404/26’s 112200 UTC 11 November kill is this afternoon, on other water. Do not treat that Cretan fiber-optic cancel as a CS MARAM cancel. Do not treat last night’s dedicated Irakleio 1441/26 void of unauthorised FA76-1127-26 as having already named MARAM. This afternoon’s companion Warning 202-26 remains a Hormuz Suspicious Activity. It does not plot 24-43.60N. Do not recast 11 November afternoon as a Karachi exclusion zone along the two-point line, a named-cable-ship casualty, a rewrite of 435/26, a rewrite of 1411/26, or a Hormuz product. The confirmed facts are NAVAREA IX 436/26, 111030 UTC 11 November, Arabian Sea / Pakistan, CS MARAM, PAK 5 (INT 7314) / 33 / 57 (INT 751) / BA 707, start 24-43.60N 066-40.29E, end 24-42.29N 066-34.75E, wide berth, FROM 11 NOV 26, no printed cancel, with dedicated 435/26 still in force on the same Wednesday table through 20 November.
What Operators Should Note
- Log 436/26 as a Pakistan Arabian Sea cable-repair line, not as a port closure and not as a Hormuz file. NAVAREA IX 436/26, 111030 UTC 11 November. Arabian Sea / Pakistan. Charts PAK 5 (INT 7314), 33, 57 (INT 751) and BA 707. Cable repair operation will be conducted by CS MARAM from 11 November along the line joining following points: START 24-43.60N 066-40.29E / END 24-42.29N 066-34.75E. Mariners are requested to give wide berth. Official file
20261111SEC 436.txt. NHO Wednesday table: first row, CABLE REPAIR OPERATION. The notice names neither IMO, MMSI, flag, RAM, VHF, numeric berth, CANCEL THIS MSG DTG nor a harbour-master closure. Hold CS MARAM. This is not 435/26, not 431/26, not 434/26, not 1411/26 / Abeille Marengo, not 1404/26 / Kobi Ruegg, and not a Karachi shutdown. - Plot the new two-point 24-43N line on Pakistan west-coast water, not on Fujairah harbour and not on a Cretan cable track. Wednesday’s start and end sit about five nautical miles apart, west of Karachi / Port Qasim, on PAK 5 / 33 / 57 and BA 707. Do not slide the line into the inner harbour. Do not invent a VHF working channel, a numeric berth, a diving window, a 2 NM halo or a night suspension. Do not promote an open-register IMO or MMSI onto CS MARAM. 435/26 remains last night’s dedicated second Fujairah SKATE 3D survey through 202359 UTC 20 November — unused as a rewrite, still in force, not cancelled by 436/26. 431/26 remains the dedicated Friday SKATE 3D survey through 132359 UTC 13 November. 414/26 remains the dedicated November Pakistan firing series through 302000 UTC 30 November.
- Give the printed 11 November start, then hold the watch until a later NAVAREA moves it. From 11 November. Issue time 111030 UTC 11 November. No CANCEL THIS MSG DTG. Do not treat the line as until further notice in the catalogue sense; treat it as a FROM 11 NOV 26 repair with no printed kill. Do not drop it at dusk on 11 November. Do not kill it at 202359 UTC 20 November because that is 435/26’s cancel. Do not kill it at 112200 UTC 11 November because that is 1404/26’s cancel. Do not kill it at 062200 UTC 6 March 2027 because that is 1411/26’s cancel. Do not invent daily working hours inside the open window.
- Keep the stale NHO rows and the in-force catalogue off the live folder. 433/26 remains the 070300 UTC 7 November self-cancelling in-force list, unused as dedicated, still ending the 2026 series at 432. 432/26 cancelled at 082359 UTC 8 November; the Wednesday listing is stale. Do not restore those numbers because they still appear on the 11 November table. Do not treat 436/26 as having already been inside 433/26.
- Keep the Fujairah jack-ups, the Kuwait survey, the Cretan cable tracks and the Hormuz files on their own sheets. 435/26 remains dedicated Southern Gulf / UAE, SKATE 3D, five corners, cancel 202359 UTC 20 November. 431/26 remains dedicated Fujairah, four corners, cancel 132359 UTC 13 November. 434/26 remains dedicated Northern Gulf / Kuwait, six named hulls, eight corners, 378/26 cancelled. 1411/26 remains dedicated Abeille Marengo, 21-point East Mediterranean track, 2 NM, through 6 March 2027. 1404/26 remains dedicated Kobi Ruegg through 112200 UTC 11 November. Official Cyprus 345/26 remains unused as dedicated. 425/26 remains dedicated Selat Storm. 420/26 remains dedicated RITI. 417/26 remains dedicated Quba. 427/26 remains dedicated Shura Island. 428/26 remains unused Amaala wrap. 397/26 remains the Port Muhammad Bin Qasim buoy-relaid caution. Dedicated 201-26, this afternoon’s companion 202-26, 200-26, 199-26, 198-26, Update 112 and this morning’s IMO 133-count on Navig8 Macallister remain their own dedicated files. UKMTO now ends at dedicated 202-26 on the Suspicious Activity line and dedicated 201-26 on the Attack line. No 203-26, no Update 113 and no IMO 134 this run.
- Karachi, Port Qasim and Hormuz are not closed by this notice. Pakistan west-coast traffic now carries a numbered CS MARAM repair line from 11 November with no printed kill, beside 414/26’s firing series through 30 November. Fujairah still carries two numbered jack-up boxes — 431/26 through 13 November and 435/26 through 20 November. Watch a later NAVAREA that moves 24-43.60N 066-40.29E / 24-42.29N 066-34.75E, adds a radius / RAM / VHF / IMO / CANCEL DTG, prints a port closure, or splits the CS MARAM line — not a completed cable joint, not a renamed Abeille Marengo, and not a Hormuz rewrite.
Regulas Shipping will keep lining NAVAREA IX 436/26 against last night’s still-in-force 435/26 Fujairah jack-up and against dedicated 1411/26 Abeille Marengo so operators can treat Wednesday afternoon’s two-point CS MARAM line as a numbered 11 November Pakistan cable-repair caution, not as a Fujairah reprint, a Cretan cable conversion, or a Karachi shutdown.
