FSU Yemen

[James Curry]

This has been going on now for a long time. You would nearly think they are just waiting for it to become an enviromental disaster.
Can they just not get a charter tanker alongside her and transfer the oil???
Charterer no need to pay them. There reward is, they keep the oil to sell on.

Yes I am sure there are legalities that would be encountered but they surely can be resolved after the oil is recovered. The oil must belong to some body so if there is a disaster they pay for the clean up.

I know there is a war going on in the region. The UN could declare a no fly zone/exclusion zone. There are enough of Naval vessels in the region from many nations could enforce the no fly zone /exclusion zone.

Looks empty the way she's sitting, but then I don't know how "over a million barrels" would look.

[James Curry]

Depending on the density of the oil, about 125,628 ton, given a a ton is 7.96 barrels.
Perhaps a major concern is she is sitting there that long now she has no longer got a positive pressure blanket of IG, in what is now the Gas space.
One would think if that was the case it is still an easy fix. Just connect up the charter vessels vapour return line to the FSU vapour return line and create a positive IG pressure in the FSU's cargo tanks, the Charter vessels tank pressure can be controlled by the mast riser or float the PD valves.

Bearing in mind the length of time it has sat there, there is a distinct possibility that the water in the cargo has settled out and will be acidic. The bottom plates may be well corroded so creating a positive pressure in the tank may well result in the bottom plates falling out
I have seen similar on shoreside storage tanks.

As long as the oxygen levels in the tanks remain below 11% the risk of explosion

In order to avoid gas explosions in fuel storage tanks, it is important to keep the oxygen level below approximately 11% by volume1. This can be achieved by using an inert gas system which spreads the inert gas over the oil cargo hydrocarbon mixture which increases the lower explosion limit LEL (lower concentration at which the vapours can be ignited), simultaneously decreasing the Higher explosion limit HEL (Higher concentration at which vapour explodes)2.

If her bottom plates are badly corroded oil leeching would be apparent around her. Water content can be measured by taking soundings by applying water finding paste the likes of Kolor Cut or by Ultra sonic sounding tapes known as UTI.

I am assuming the FSU is now a dead ship and her in built equipment is no longer functioning.
Anyway the polution risk is not going away be the likes of the UN sitting around going we are all doomed. I am sure an oil major like Aramco/Shell/BP could soon resolve the problem.

Apart from this vessel there a large number of aged tankers carrying russian crude around the world. They have no insurance, often out of class and sailing under flags that have little or non flag surveys and virtually untraceable owners.
