At the stern a 4 bladed iron propeller is still attached to the tail shaft in a V section of the keel. The hinge that would have held the rudder arches round the propeller where the stern has collapsed to port. Inside the keel section the propeller shaft continues a short way forwards before breaking at a flange marking the end of a section.
A pair of bollards have fallen well off to the starboard side of the wreck, indicating that they must have fallen from the stern before it collapsed in the other direction.
On the centre line of the wreck the propeller shaft continues forward again with a slight bend, maybe a result of stress before the bolts holding the aft section in place fractured. This area of the wreck would have been in the middle of the aft holds, but there is no sign of any cargo. Neither the iron ore carried by the Ibis or the antracite the Heidrun was carrying.
The Heidrun was fitted with a 2 cylinder compound engine. The starboard boiler is rotated through 90 degrees to point across the wreck and broken open to reveal the fire tubes. In contrast the port boiler lies precisely in place.
Alongside the port boiler I though at first that a smaller cylinder with rounded ends could have been a condenser. However, considering that the engine was a more primitive 2 cylinder compound engine, I think this is more likely to have been a steam reservoir. A corresponding cylinder associated with the starboard boiler is broken open to reveal a hollow interior. A condenser would have contained a mass of copper plate or tubes and has most likely been salvaged.
Forward of the boilers is a fair scattering of coal, showing that there would have been a single bunker across the ship rather than a saddle configuration either side of the boilers. There is no sign of coal anywhere else on the wreck, so it is unlikely to have been the anthracite cargo which I suspect was light enough to have been washed away.
Almost amongst the coal is the end of a mast which has fallen along the centre line of the ship. The remains of the winch that would have been associated with the mast are well off to starboard. Following the mast forward, there are again no signs of iron ore or antracite across the area that would have been the forward hold. The other end of the mast rests next to a large pile of anchor chain which spreads to the port side of the wreck.
The bow is well broken and has fallen forward and to starboard leaving the anchor hawse pipes exposed. An anchor pokes half out of the port side.
At the top of the bow, the furthest forward point on the wreck, a crane for lifting anchors over the side is stretched out along the seabed. With the bow falling to starboard, the anchor winch is located upside down near the top of the haws pipes. Chain leads from the anchor, through its hawse pipe, under the winch and back to the pile.
