Investment In Design

Navale Morini, the 12,000-dwt Turch- ese provides a new platform for the

ABB system based on two 3,300-kW

PWM(Pulse Width Modulation) drives.

PWM technology, whereby frequency converters control sturdy, standard induction cage motors, offers system simplicity, reliability and efficiency fac- tors, maximum torque in either direction and other operational plus factors such as an exceptionally high power factor, soft start and smooth control. Hitherto, the concept has been mainly employed in the marine environment on offshore vessels and cablelayers.

Finbeta runs a modern fleet of ice- classed, IMO type II stainless steel chemical/parcel tankers, and the ice- classed Turchese has started life in the

North European and Baltic petrochemi- cal trade. years, from eight percent to 35 percent.

Italian platform for electric drives

Italy's private shipowning sector, fun- damentally concentrated in relatively small or family-owned businesses, con- tinues to demonstrate both resilience and flair, and a receptivity to new design and engineering concepts. In the latest demonstration of a holistic and far- sighted approach to newbuild powering,

Savona-based Finbeta has endorsed diesel-electric propulsion in a new chemical tanker application.

The Finnish-developed system involved, distinguished by its elimina- tion of the usual need for propulsion transformers, was selected by virtue of a clutch of cost, efficiency, operational and space- and weight-saving benefits.

It was only chosen after detailed evalua- tion of the various powering options, starting with consideration of a typical, diesel-mechanical configuration.

Constructed at Ancona by Cantiere

Over our 50-year history in marine keel cooling engineering and manufacturing, R.W. Fernstrum &

Company has built a reputation of quality and service, worldwide.

Throughout the years, we've made improvements in durability and efficiency to our GRIDCOOLER® line of keel coolers. Today, we're taking our product's efficiency to a higher level.

Introducing the

ENHANCED

GRIDCOOLER from R. W. Fernstrum

By using an enhanced surface on the interior of our tubing, we've increased the heat transfer capability of our keel cooler by up to 30%. On large installations, this can reduce the number of coolers required for an application. It also allows us to fit keel coolers in spaces that previously were too small.

This new advancement shows our commitment to innovation in a field where we've long been the leader. If you need a solution to a cooling problem, give us a call.

We will gladly work with you to design a keel cooling system to meet your needs. when you thought we could] get cooler!

Horizon To Build OSV Trio

Horizon Shipbuilding and SLOK

Nigeria Limited have signed contracts for the construction of three offshore vessels — all of which will operate under a long-term contract with Mobil

Producing Nigeria Unlimited.

The contract calls for Horizon to build a 200 ft. (61 m) steel Single Point Moor- ing (SPM) Oil Spill Response Vessel with a total of 4,000-shaft hp.

The vessel will be fitted with control- lable pitch propellers and a dynamic positioning system, and will be con- structed to ABS class requirements for unrestricted service, thus meeting all

SOLAS requirements.

A second contract calls for Horizon to construct two 155 ft. (47.2 m) aluminum crew boats for SLOK Nigeria. The ves- sels, which total about 4,000-shaft hp, will be driven with five propulsion shafts. The crew boats will carry 95 pas- sengers, liquid cargo and a deck load of 180 tons. In addition, Horizon Ship- building formalized a contract with

Dixie Towing, Jacksonville, Fla. for the construction of a 70 ft. (21.3 m) Z-drive tug. Designed exclusively for Dixie by

Glowacki Engineering, also of Jack- sonville, tug is scheduled for a fall 2000 delivery.

NOL Group Subsidiary

Contracts New Tankers

The NOL Group reported that its wholly owned subsidiary, American

Eagle Tankers (AET), has contracted two new double hulled very large crude carriers (VLCCs) to be constructed by

Hyundai Heavy Industries of South

Korea.

The new tankers will become part of

AET's current 18-member Aframax fleet upon their delivery in 2002.
