Maintenance - Exhaust water injector

The exhaust changer, injecting coolingwater into the exhaust pipe was blocked. 

Maintenance 2013 Valves replacement

In 2013 I replaced all valves and fitting with maritime bronze ones. This long term investment was quite expensive, but sea-valves is one of these things you should not got for standard, but buy best.

Also very important, as bronze is the most noble metal sea-valves are made of, they are safe from electrolysis corrosion between ships. These valves are totally worry free.

Note, the Anode is fully intact. That proves, taking of the electric landline (if not at home) pays off.

Engine room on BB

Removed the spare valves in the aft cabin, wich have been installed for an optional 2nd toilet. I didn't like the idea and prefer having a chemical toilet in the aft cabin complementary to the sea-toilet in the front.

Maintenance NMEA 2000

Today our ship will make a step forward into a new generation of electronic systems. I will install a new generation bus system, NMEA 2000. This bus is quite practical because it interconnects all instruments and exchanges all information (wind, speed, log, gps, ais, autopilot, and engine supervision). This is a great advantage (only one cable) and at the same time its biggest disadvantage. There is absolutely no redundancy. If this bus fails all instruments, except the plotter fail. The solution is an old fashion Forumo GPS as backup. Later I have to replace step by step the vdo sl instruments.
