Ship & Boatbuilding Technology:

The Containership Norasia Fribourg (Continued from page 27) portedly allows it to carry up to 47 percent of the containers as 20- footers. The Panamax breadth al- lows 11 containers in the hold and 13 over deck in the athwartships lattice. The gaps between the 13 containers stowed next to each other topside amount to only 1.8 in. (45mm). Consequently there are T- shaped cell guides and, for easier container handling, insertion guides placed alternately high and low. • Propulsion Package. HDW says the slow-speed, 2-stroke diesel

Mitsubishi 7UEC 85 LSC engine plant driving a fixed-pitch propel- ler is economical, reliable and easy to maintain. The streamlined aftership and arrangement of the main engine in the hold area called for a very compact engine room, making optimum use of space. The engine has a nominal output of 27,290 kW (37,100 hp) with 102 min 1 rpm and a low specific fuel con- sumption of 165 g/kWh (121 h/hp).

We've just taken another step ahead by going astern.

When you're firmly established as a world leader, it can be easy to become complacent.

But for HamiltonJet, quite the reverse is true... literally.

As the first to introduce the split duct deflector for superior astern thrust and vessel manoeuvrability, HamiltonJet has just advanced this concept another step.

The result is the patented HSRX servo- hydraulic follow-up control system. This major advance in applied hydraulics features a unique rotary valve integral with the deflector actuating cylinder.

The new HSRX gives full follow-up movement with enhanced reaction time and precision at the zero-speed position... simply. And all with inboard hydraulics for long life and easy maintenance.

HamiltonJet.

Definitely not astern in going ahead.

Circle 215 on Reader Service Card design is flexibility with a minimum of maintenance. At sea the entire shipboard network, including 100 reefer containers, can be powered by thruster-controlled, shaft-driven generators (1,500 kW). The two diesel generators (1,450 kW each) can be added if needed. The two generators can provide the entire electrical requirements, including reefer containers — so the ship can be driven, depending on the number of reefers and the rate of speed, by either the shaft-driven generator alone or just by the generators. The diesel generators are set up to be run on heavy oil for continuous op- eration, or on diesel oil. Fully laden, the open top containership has a service speed of 22.5 knots with the main engine running at 90 percent

MCR and 15 percent sea margin. In its trials, the Norasia Fribourg achieved a speed of 24.2 knots. The ship is also fitted with a Becker rudder and a 1,300 kW bowthruster to improve maneuverability. • Automation and Electronics.

The entire ship's operation is moni- tored and controlled by the ship's operating center. In addition, the engine plant can be operated from the ship's management center.

The Norasia Fribourg is fitted with HDWs integrated automation system, CAMAC (Centralized Alarm,

Monitoring and Control). This sys- tem comprises, among other things, two master computers and four workscreens. The data is gathered decentrally by intelligent substa- tions; in the event the master com- puters fail, these stations can oper- ate the ship safely. The ship's log is compiled automatically, saving work and relieving the ship's personnel.
