World's Largest Surface

Effect Ships To Be Built

By Norwegian Shipyard

An order for the world's largest high-speed surface effect ships (SES), the first of their kind to carry hoth cars and passengers, is soon to be placed with a Norwegian ship- yard by the Tonsberg shipping com- pany Fekete.

The Bergen-based design compa- ny Cirrus will be responsible for designing the new large version, which is intended to measure about 177 feet in length compared to 114.8 feet for the company's present de- sign, and SES specialist Brodrene

Aa will build the vessels. Delivery is scheduled for 1990-91.

Representing a cross between hovercraft-type air cushion units and catamaran hulls, these vessels are able to attain speeds in excess of 40 knots in regular traffic.

Cirrus has collaborated with Bro- drene Aa, a yard at Hyen on the west Norwegian coast, since 1981.

Warren Screw Pump Meets

High Viscosity Demands

A versatile, positive displacement pump ideal for pumping high vis- cous liquids is available from War- ren Pumps Inc., Warren, Mass.

Designed to efficiently pump liq- uids with viscosities to 150,000,000 ssu or more, the Warren 2200 series screw pump handles capacities to 9,000 gpm and discharge pressures to 700 psi, at speeds to 1,800 rpm.

The pump is well-suited for use in a wide range of applications, includ- ing chemical processing, petroleum, petrochemical, power, barge, and vacuum system services.

The Warren 2200's ability to pump non-lubricating and highly viscous liquids, like polymers, adhe- sives, oils, lard, molasses, and syn- thetic rubbers, stems directly from its innovative pumping screw de- sign.

Basically, the design consists of two sets of meshed rotating screws, timed and driven by externally lu- bricated, herringbone-style gears that are manufactured from heat- treated steel. The screws convey liq- uid toward the center of the pump where the discharge port is located.

The design creates a bi-direction- al pumping action that eliminates thrust and provides a hydraulically balanced pump. It also ensures a quiet pulseless flow, increasing the pump's efficiency.
