Ȥtt> for cargo, washing and ballast.

The ship's power management sys- tem was configured to the shipowner's exacting specifica- tions, and offers seven modes of operation — from harbor mode to sea- going mode to dis- charge mode — allowing the opera- tor the maximum possible control over the ship's efficient use of fuel.

Additionally, the cargo handling system enables the operator to select one common pressure set- point at the manifold and let the system control the speed of the electric driven cargo pumps, in automatic parallel (1 to 16), to obtain the selected set point.

In keeping with the advanced monitoring, control and communi- cations outfitting, Mariella

Amoretti has installed a

Fleetmaster system which allows the shore office to call the vessel

Shaft generator A.V. Kaick via Satcom and receive all measur- ing data from the Automation

System. This means that this data file is shown on the PC at the shore office as it is onboard the vessel.

In keeping with the safety theme, the ship is fitted with a shaft generator which can also be used as an electrical drive motor for propulsion. In case the main engine fails or the master decides to run the vessel with a lower speed, the main engine can be cou- pled off and the ship can be pro- pelled with the electric motor only.

During sea trials, a speed of 10 knots was reached using this method, far above the three knot speed required by RINA. Further, the ship is fitted with a bowthruster and a sternthruster to maximize maneuverability.

Sureness of ship movements is additionally enhanced with a

HSVA high-efficiency rudder. The (Continued on page 52)
