A ship can be easy to see at night and still be difficult to read.In this episode, we look at how deck lights, accommodation lighting and floodlights can interfere with the navigation lights that bridge teams rely on to judge vessel aspect, movement and collision risk. The discussion also considers what the COLREGs require and why the complete night-time appearance of a modern ship deserves more attention.Read the full DeepDraft analysis:https://thedeepdraft.com/2026/09/21/navigating-in-a-sea-of-visual-pollution/
Full Weekly Brief:https://thedeepdraft.com/2026/09/20/hormuz-control-cyber-risk-shipboard-competence-september-20-2026/This episode of the DeepDraft Weekly Maritime Brief covers the September 20, 2026 edition: Hormuz control, Saudi crude disruption, sanctions exposure, tanker cyber risk, Bab el-Mandeb protection planning and shipboard competence under SIRE 2.0.The central operating signal is clear: route availability is not the same as voyage readiness.
The deck seal’s appearance and its HVPQ entry did not agree. Checking the maker’s manual raised a question with consequences for operation, troubleshooting and inspection.This episode of DeepDraft Conversations explores the confusion between wet and semi-dry deck seals, and why crews need to understand the design actually fitted.Read the full analysis by Capt. Raghu Sharma:https://thedeepdraft.com/2026/09/14/deck-seal-looked-wet-semi-dry-water-displacement-tags/AI-generated discussion based on DeepDraft’s original analysis.
Full Weekly Brief: https://thedeepdraft.com/2026/09/13/bab-el-mandeb-gulf-tanker-risk-september-13-2026/Two chokepoints now carry active control pressure. In the Red Sea, Houthi movement around Bab el-Mandeb has pushed routing confidence, naval coordination, insurance cover, and crew-risk acceptance back into the centre of voyage planning.In the Gulf, tanker strikes, reduced Hormuz traffic, and record VLCC rates are turning passage approval into a commercial and security decision before the vessel reaches the lane. This episode also looks at AI-enabled targeting preparation, Gulf of Aden piracy response, fatal vessel-fire casualties, and this week’s DeepDraft analysis on tanker enclosed-space entry permits and CO₂ testing.
Why is CO₂ on the enclosed space entry permit? This episode explores the questions around oil tanker gas testing, SIRE 2.0 and the reasoning behind safety checklists.Read the full DeepDraft analysis:https://thedeepdraft.com/2026/09/07/co%e2%82%82-on-oil-tanker-entry-permits-safety-requirement-or-checklist-overreach/
Full Weekly Brief:https://thedeepdraft.com/2026/09/06/hormuz-tanker-strikes-ais-silence-maritime-security-september-6-2026/This week’s DeepDraft Weekly Maritime Brief covers Hormuz tanker strikes, AIS-off transits, SIDR fatalities, Black Sea CPC loading risk, vessel seizure in Svalbard, and wider maritime security pressure.
A tanker switches off AIS while passing through the Strait of Hormuz. Public tracking stops, yet the vessel remains detectable by radar, satellites and other surveillance systems.This episode examines what “going dark” actually achieves, why legitimate security decisions can resemble concealment, and how a broken AIS track can become a compliance problem for the Master and company.Read the full DeepDraft analysis:https://thedeepdraft.com/2026/08/31/dark-transits-in-hormuz-the-illusion-of-disappearance/
https://thedeepdraft.com/2026/08/30/hormuz-confidence-black-sea-booking-risk-august-30-2026/Hormuz has not returned to normal operating confidence. Tanker warnings, low Strait traffic, Black Sea incidents, Panama Canal restrictions and rising freight pressure are now moving into the same commercial risk file.This Weekly Maritime Brief also connects those operating pressures with DeepDraft’s latest analysis on tanker fire wires and the wider question of whether safety controls can work under pressure.
