A bit of shipping industry insight for you. On the top two pictures you can see laid out in rows a number of flexible hoses - they're the grey things that look a bit like over-sized worms. In the third picture they have been re-shaped by the force of the waves hitting the decking where they are stowed.
A lot of the ports where the vegoils are are loaded and discharged have pretty basic facilities - in some cases insufficient hoses or hoses in too poor condition to have the cargo either loaded or discharged. So these ships that are regularly in this trade tend to carry several lengths of flexible hoses themselves - nothing worse than being stuck in a port somewhere and wasting time which could threaten the vessel's next business, just because a hose wasn't available.

I've found a few photos from an incident in a West African port. The ship we had on charter didn't have any hoses on board (happens sometimes), and the shore wanted the vessel to use these hoses - the captain wasn't happy about it and eventually once he threatened to sail without discharging the shore crew made the effort to get hold of some newer hoses. First picture shows the hoses when they were first offered to the vessel - they were immediately rejected - the pressure-damage that might result from pumping product through them was too high a risk - there was a real danger they would rupture completely.

So the shore gang said they would repair them so that there was no risk. This was their repair.

The captain was having none of it, but they still insisted on connecting the hose to the vessel's lines so that they could show the captain that even if the hose did leak they had an anti-pollution measure in place. It was at this point that the captain said he'd had enough - really, this was a brave move on his part as it is quite common for armed police to be called who will then arrest the captain and throw him into a cell for failing to deliver the cargo to their country.

Like applying a napkin to a severed artery...

Excellent simile, SG.

Here are the two pictures of the vessel in the rough seas that I couldn't edit earlier:
