Depth, molded (hull): 5.4 meters
Maximum Draft: 4.22 meters
Tank Capacities
Fuel Oil: 171 m³
Fresh Water: 30 m³
Foam: 20 m³
Z-drive Hydraulic oil: 0.5 m³
Sludge: 4 m³
Oily Water: 4 m³
Main engine lube oil Sump: 13 m³
Main engine lube oil storage: 0.8m³
The vessel has been outfitted for full accommodation up to crew of 14. Master’s cabins are located on the main deck, with chief engineer and three additional four crew private crew cabins, located on the lower accommodation deck. A spacy mess/conference room is placed in the deckhouse.
