Maersk edges back into the Red Sea and completes another Bab el-Mandeb transit

Maersk confirmed that the U.S.-flagged Maersk Denver (voyage 552W, MECL service) transited the Bab el-Mandeb Strait into the Red Sea on Jan 11–12, 2026, using heightened safety measures and direct customer communications. Maersk also emphasized this remains a stepwise approach with no additional sailings announced yet, which matters because even a limited restart can change how insurers, shippers, and carrier networks price timing risk and optionality for the Suez lane.

Maersk sent another MECL ship into the Red Sea, but kept the restart limited

Maersk said the U.S.-flagged Maersk Denver (552W) transited Bab el-Mandeb into the Red Sea on Jan 11–12, 2026 with necessary safety measures, and customers with cargo onboard were informed directly. Maersk also said it will continue a stepwise approach and has no additional sailings to announce yet.

  • Optional routing returns, not a full network flip
    One successful passage helps planners model Suez as an option again, but repeatability is the real threshold for schedule redesign.
  • Time savings versus risk-cost adders
    The core trade is fewer days and less fuel versus war-risk, security posture, and uncertainty around corridor thresholds.
  • Container knock-ons arrive first
    Any partial return affects strings, buffer time, and equipment cycling before it shows up cleanly in base freight benchmarks.
Bottom line
Maersk’s Denver transit is an incremental reopening step: it does not rewrite global capacity overnight, but it does reopen the corridor’s option value, which can shift planning, clauses, and timing assumptions quickly if passages become repeatable.

Maersk Denver’s Jan 11–12 Red Sea entry
Quick take Confirmed details Immediate operational effects Commercial impact path
Transit completed Maersk said Maersk Denver (voyage 552W) transited Bab el-Mandeb and entered the Red Sea on Jan 11–12, 2026. Re-activates playbooks for routing, security measures, and contingency comms around that corridor. Even one confirmed passage narrows uncertainty for planners building “Suez optionality” into schedules.
Service context The ship is operating on Maersk’s MECL service; customers with cargo aboard were informed directly. Network teams can test real-world timing and coordination without committing entire strings. Shippers watch whether this becomes repeatable, which affects bookings, buffers, and surcharge posture.
Safety posture Maersk stated “necessary safety measures” were applied during transit. Higher security posture can add cost and complexity, but it can also reduce the need for Cape diversions. Risk-cost shifts show up first in insurance conversations and clauses, not always in base freight.
Scale remains limited Maersk described a stepwise approach and said there were no additional sailings to announce at this time. Most voyages still route as before, so global capacity math does not flip overnight. Markets can still reprice “option value” for the corridor even when actual volume is small.
Early indicator for 2026 planning The move fits a cautious, incremental re-entry posture discussed by Maersk in recent updates about Red Sea operations. Supports internal planning for alternate routings if security thresholds stay acceptable. Container networks see the biggest effect first, but knock-ons spread to equipment positioning and intermodal timing.

Red Sea routing optionality is being tested again, one voyage at a time

Maersk says Maersk Denver completed a Bab el-Mandeb transit into the Red Sea on Jan 11–12, following the earlier MECL passage by Maersk Sebarok in December. Maersk also said this remains incremental, with no additional sailings announced yet.

Recent tape (Maersk-confirmed)

Dec 18–19, 2025

Maersk said Maersk Sebarok completed an MECL transit through Bab el-Mandeb and the Red Sea with “highest possible safety measures.” Customers with cargo were informed directly.

Jan 11–12, 2026

Maersk said Maersk Denver (552W) completed another MECL transit into the Red Sea with “necessary safety measures.” Customers with cargo were informed directly.

Current stance

Maersk said it will continue a stepwise approach and that there are no additional sailings to announce at this time. Security thresholds remain the gating factor.

Network mechanics that move first

Vessel-day supply effect

When a string switches from Cape to Suez, round-trip time can shrink meaningfully. That frees ships, or allows higher buffer without adding hulls.

Schedule risk shifts, not just transit time

Shorter distance helps, but reliability depends on security thresholds, convoy-like procedures, and how consistently passages can be repeated.

Equipment positioning

Long Cape loops can trap boxes and chassis in the wrong place. A partial return can tighten or loosen equipment depending on which services switch first.

Commercial knock-on

The earliest “price” can show up in clauses, insurance discussions, and optional routing language before it shows up in base freight indices.

Practical exposure map (who feels it first)

Container networks

String design and buffer strategy

The value is in repeatability: one transit proves feasibility, multiple transits drive planning changes.

Shippers

Inventory days and booking behavior

If Suez becomes viable for select loops, lead times can compress on those lanes, and safety stock assumptions change.

Insurers and contracts

War-risk and routing language

The near-term work is documentation, quote cadence, and risk allocation language for transits.

Ports and terminals

Call bunching and berth windows

A shift in routing can change arrival bunching patterns and the timing of import box surges.

Cape vs Suez Scenario Tool (timing and cost)

Directional calculator to translate “route choice” into days, dollars, and an operational feel. Use your own assumptions (daily cost, fuel burn, war-risk adders). Output is illustrative.

Gross cost saved (USD)

$0

Days saved × (ship cost/day + fuel cost/day).

Net benefit after adders (USD)

$0

Gross savings minus war-risk/security adders.

Vessel-days freed (per week)

0

Days saved × weekly strings (a rough “capacity feel” number).

Impact bars (relative weight)

This is a simplification, but it matches how operations teams feel the change first: time and fuel deltas can be large, while risk-cost adders decide whether the corridor stays “optional” or becomes “default.”

Maersk is framing the Red Sea move as a controlled, incremental return: a completed transit with heightened measures, direct customer communication, and a stated intent to proceed step by step while security thresholds remain the gating factor, with no broader network change announced yet.
