Hold Washing: When Clean Is Defined by Contract
An engineering and authority analysis of the bulk carrier hold washing system (SYS-035) — why its completion criterion comes from the charterparty rather than a regulation, and what that changes about its cyber exposure.
Gas Bunkering: A Safety Function Across Two Hulls
The ESD link and vapour-return line of an LNG bunkering vessel bind two ships into one safety function. An engineering and authority analysis of SYS-215.
Red Kraken and the Maritime Logistics Stack: What Agentic Cyber Strategy Changes for Ports and Shipping
A July 2026 CSIS tabletop exercise used a custom AI “red agent” to play Beijing during a fictional Taiwan crisis. Its most useful lesson is not a prediction of one specific port attack, but how an adaptive adversary can move around hardened facilities and target the software, identities, data, and s
IACS UR E27 Asks You to Prove Up to 41 Applicable Security Capabilities — None of Them Inspect the Model
UR E27 asks equipment suppliers to prove 41 security capabilities by test. Every one of them was written on the assumption that software is deterministic — and some of the systems now arriving at class review are not.
When National Cyber Regulation Becomes a Ship Requirement — CIRCIA, the MTSA Cyber Rule, EO 14028 vs. IACS UR E26/E27
Three U.S. instruments and one class standard reach the same hull from opposite ends of its life.
One Ship, Three Layers — Unifying NIS2, CRA, and IACS UR E26
Three regulations, three units — organization, product, ship — meeting on the same hull.
[Spotlight Post] Not Every Ship Is the Same Target: Cyber Risk by Type and Size
Tankers, container ships, LNG carriers and cruise ships face different threats — and vessel size and automation reshape the attack surface. A read through the lens of geopolitics.
