HAL's Vista Sails with ROCHEM Technology

The MS Oosterdam is Holland

America Line's (HAL) second 1.848- passenger Vista-class ship. Delivered by

Fincantieri Cantieri Navali Italiani,

S.p.A., the ship includes some of the most sophisticated technical and envi- ronmental advances of any ship afloat.

Many advances are below deck, well outside of the view of the passengers.

For example, the engines are situated in two separate spaces that can be com- pletely closed off from each other so that in the event of an emergency in one engine room, power systems in the other will still provide sufficient propulsion and electrical power to return the ship safely to port. The General Electric gas turbine also located in a separate room provides a third backup system and also allows the ship to operate without visi- ble pollution in sensitive areas such as

Alaska. Helping the Oosterdam to have a zero impact on the environment is the ship's Rochem system of sewage treat- ment. a purification system that treats all the water used on the ship. The gray water, which comes from showers and sinks and laundry water, is recycled and used for various technical things on the ship such as cooling water. Another part of the Rochem system treats the sewage, or black water and galley drain water.

The water that comes from the Rochem system for discharge is purified to a near drinking water quality. This is another way that Holland America is working to preserve and protect the marine envi- ronment. The advanced wastewater purification systems supplied by

ROCHEM have been installed on the

Vista Class ships built at the Fincantieri yard in Marghera, Italy. ROCHEM was contracted to supply two purification units: I) Grey Water Treatment System (GWTS) to purify the accommodation and laundry water generated onboard the Vista Class ship and 2) Black Water

Treatment System (BWTS) to purify the sewage, galley water and concentrate from the GWTS generated onboard the

Vista Class ship. With these two purifi- cation systems provide a treatment capacity of 850 m3/day (224,400 gal- lons/day) for the 85,000-ton vessel.

Both the GWTS and BWTS carry the latest IMO certifications and are designed to meet the most strict world wide discharge standards, e.g., Alaskan discharge standards defined by the

Murkowski law. Utilizing ROCHEM's 30+ years of maritime experience, these advanced waste water purification sys- tems are modular design for ease of

Included with supply is a high level of redundancy by designing for operating and maintenance flexibility. (Continued on page 76) "Now with leak detection"

Smart Radar Level

Sensor with Generic

RS485 Output

The first flat array antenna for liquid tank gauging.

This software driven array allows for each sensor to remotely configure itself for the type of product as well as the structural characteristics within each tank. It is completely self-diagnostic and is factory calibrated using a laser interferometer to •1mm. It is designed for the harshest environments and can be provided in a high temperature version to 385°F. it is intrinsically safe with Class 1, Div. 1,

Group D & C approvals. As a smart sensor, all processing calculations and software are resident in the device itself, only a high level generic data output, i.e., RS485 (or others on request) is sent to the cargo control area.

Options: • Multiple alarm set-points • Temperature • PV Pressure • I.G. Pressure • Tank Management Software • Automated draft and trim
