🚨 UPDATE: Container ship ONE Henry Hudson has been towed out to anchorage outside of the breakwater. The fire onboard has been substantially contained. Fire crews and ship crew members are continuing fire suppression efforts.

This is the Pilot Card. For me, at the moment, very important : windage area: 16,681m² (179,552.79 ft²). With force 7 on the beam, that's about 177 tonnes-force created by the wind.

I'm inbound with CMA CGM St Germain. Length 400m, breadth 61.30m. Gross Tonnage 237,742. Max container capacity 23,876 TEU. It's wind forces 7 at the moment.

This is why you might see a fireboat not spraying water on the fire itself but on the "boundaries" around the fire. This is called "boundary cooling" and prevents the fire from spreading to adjacent spaces.

25/x What about the EDG? It took 70 seconds for it to start. Regulations say it should be 45sec, but even then, an EDG can not run a ME of a ship. (a damper limit switch didn't indicate it was open for the EDG to start)

24/x Why didn't breakers HR1, LR1 and transformer TR2 kick in automatically after tripping? Because they were set on manual. There is no regulation that requires them to be set on automatic. If they had been, critical systems might have become available earlier.

22/x An FLP is used for what the name says: to flush your fuel lines when switching over from one type of fuel to another (e.g. MGO to low sulphur fuel), not as a service pump to a DG. A FLP does not start automatically after a black-out (contrary to a service pump)

19/x During construction of Dali, these labeling bands were placed on to the ferrule. This made the ferrule thicker and as such, could not be fully inserted in the terminal block and wire 381 was just sitting on top of the clamp, creating a bad connection, and a black-out.

18/x The part of the wire called the "ferrule" is inserted in a terminal block with a clamp inside. This secures the wire. The labeling band, with the number on, should be away from the ferrule so the ferrule can completely be inserted in the terminal block

17/x Think of your fuse box at home. Wires going in to the fuses. It's the same on a ship, but many, many more wires. They need to be labeled and that's what's done with a small band, with a number on, around the wire .

16/x At 012909 the crew manually restart FP for DG3 and DG4. It's also the time the Dali hits the bridge with a speed of around 7,5kts. OK, these are the events in the PMS. But WHY did HR1 trip in the first place?

15/x the bank on the PS aft, creating a rotation to SB. (bank effect) Having the rudder full to PS, with no prop turning is not able change that movement. Systems start booting up again. (also the fuel pump of DG2, which was in automatic, contrary to the FP of DG3 and DG4)

14/x As you can see, Dali is still turning to SB (right). why? A ship creates a positive pressure wave at the bow and a negative pressure wave along the hull and at the stern. Dali had some deeper, open water on the SB side. The negative pressure "sucked" the stern towards

13/x 3 sec. later, DG2 is running at a sufficient rate of speed to be connected to the HV bus and the PMS does so. Pilot orders PS anchor let go and rudder full to port. 012736 crew manually engages breakers HR2 and LR2 through TR2. This restores the LV bus.

11/x 012610 the Emergency Diesel Generator (EDG) kicks in. Emergency lighting comes back on. 012704. DG3 and DG4 run out of fuel and start stalling. The PMS FIRST disconnects them and THEN starts DG2. As such a 2nd black-out occurs over the HV and LV system. The EDG provides

10/x DG3 and 4 keep running while they consume fuel that is left in the supply lines. The vessel speed is 8,6kts and starts turning right (starboard) with a ROT (Rate of Turn) of 4°/min. Senior pilot orders 20°PS rudder.

8/x At 0125 breaker HR1 unexpectedly opens and the ship experiences a LV black out. It loses the BT, steering gear (SG) pumps (to turn the rudder), lighting and at 012508 (8 seconds later) the ME (Main Engine) Cooling water pumps. This triggers an automatic shutdown of the ME.

7/x A 440 Volt low voltage (LV) electrical bus was also connected to the HV bus via a redundant step down transformer TR1 or TR2. The LV bus powers vessel lighting and other equipment including steering gear pumps and the main engine cooling water pumps

3/x engine if supporting systems required for its operation, such as the lubricating oil pump or cooling water pump, were lost. This becomes important later in the story. About 0036, the two tugboats pulled the Dali away from the dock.

The Maersk Connector (loa 138,35m) has the ability to load and lay 2 cables at the same time due to having 2 carousels. Each carousel can hold 3500ton of cable, and the vessel can lay cable with a speed of 1200m/hr. She is also designed for shallow water ops.
