An interesting thing about the Helge Ingstad is that two important aspects of the incident, the AIS and flooding are at completely different levels of safety defense. It could be likened to sports, a soccer game for example. First line of defense is to keep the ball in your possession and at …

Electrical power on a ship is important. Typically at sea one generator is kept on-line while a second is on stand-by, ready to start automatically if the on-line generator fails for any reason. The third generator is either undergoing maintenance or is the second back-up, in case the generator o…

It’s a good analogue. You could also think of “active” and “passive” safety: the former refers to what the crew does to avoid the incident and, if unsuccessful despite their best efforts, mitigate the consequences, and the latter to general design, structural strength, watertight integrity, vessel …

Many of the risk assessment systems speak of “preventive” controls and “mitigating” controls. That basic outlook could be applied to ship design - if an owner is willing to look beyond class or flag only requirements.

Another point is everyone involved is working with restraints, time, money, information, understanding, none are available in unlimited quatites. The officer who made the decision to come left at the last minute was working within very tight time limits and with very limited or flawed understanding…

Revisiting old posts (because it was suggested I do so, he he he) Having a “coherent game plan” to go with your analogy is also a fundamental aspect to gain a win (a safe voyage). Clearly the foolish idea of turning off your AIS in coastal VTS waters was a losing idea to start. Situational awaren…

Not to forget that only one compartment was up-flooded due to the collision and that the ship sank due to progressive flooding through open watertight doors. However, who cares? Naval ships do not comply with neither Solas nor ISM and can operate and be designed as they like.

[image] Heiwa: the ship sank due to progressive flooding through open watertight doors Do you have a source on that? I tried a search or two after seeing your comment, and I find no credible references. On the other hand, I find plenty of mentions of the failed watertight integrity of the s…
