I aggree with you Captain Confusion, but that's Yankee engineering. The people designing these ships used to build Lakers for carrying iron ore and it seemed they were cheap and cheerful but never went deep sea.
They were the same ships with the CJC tank and pump which you can see in the port aft corner of the image. Bottom plates were all open grid and any deck above was checker plate, no teledips on fuel tanks or LO tanks, just sounding pipes. It was a right performance when they came to check the fuel consumption on trials. The Mechanical Design boss came up with this roughly meter cube tank on top of the control room which was connected to the fuel system, it had a sounding pipe , not sure if it had a weighted cock, but the hot HFO was foaming and shooting up the sounding pipe.
They already had two certified fuel meters in the system, one on the supply and one on the return, but he didn't trust them.
It wasn't a success. If Sulzer says the engine burns X kg/bhp/ hr calculated on a test bed and by mathematics then that should be good enough. How was his mickey mouse system going to prove otherwise. It looked good paper I suppose. On subsequent ships they didn't bother. Looked too dangerous to me.
