Under The Waterline

Today I got an invite down to the world of Hades from our Chief Engineer.

The subterranean (or should that be sub-mediterranean) engine room is a world I love to visit.

The engineers have been nagging me for a few days to connect up a rudder feedback potentiometer on the rudder stock.

This "pot" basically feeds details about rudder position, electrically back to the wheelhouse.

The steering gear was removed in the shipyard for an overhaul.

Ours is only a small ship of about 80m length, but the steering gear is the size of a smart car.

They cut a hole about ten feet square in the deck above the steering compartment, lifted the steering gear out with a crane and overhauled it ashore.

It was subsequently put back and the deck re-welded into place above it, once again sealing the compartment.

I love going down into the engine room through the watertight doors.

It is deafening even with only one Mitsubishi generator running.
We have two auxilliary gensets, two main engines and two shaft driven generators.

You wear ear defenders, communicate by shouting at each other or using sign language and they have all the tools, workshops and big machinery you could ever wish for.

The engines are started by compressed air, the cylinders are big enough to climb in and they have acres of computer monitors and instrumentation to watch in the engine control room.

The ship has to be largely self-sufficient when at sea, so they carry a full metalworking workshop, spares and a wide range of raw metals - a plethora of cables, steel bars, wood, plating and all sorts.

I really am torn between whether I like to play with electronics on the bridge or the big machinery like shaft generators and three phase switchboards down in the engine room.
