SMM '80 (continued from page 17) drilling rigs. Scientists from Ber- lin Polytechnic will use an off- shore power station of the EPOS system as an example in explain- ing their hydromechanical inves- tigations, and an expert from the

U.S. Department of Commerce will deal with the inspection of the huge floating OTEC power stations made from prestressed concrete, as well as the repair and maintenance work aboard these giants.

Submersible Systems

Six more papers at the congress are concerned with the technol- ogy of submersible systems. Af- ter a general survey of the field by J. Gelhaus of Dragerwerk AG, some specific examples of this technology will be presented, such as the FUGE system — an un- manned, remote-controlled vessel for inspection and maintenance of offshore installations. M. Muller of

Preussag will report on its devel- opment. B. Arndt of Schiffko, G.

Haux of Haux-UW-Systemtech- nik, and H. Victor of Ocean Con- sult will explain SUPRA—a new system for underwater operations that has been developed in Ger- many.

On the basis of model experi- ments, P. de la Motte of Ingen- ieurburo fur Wasserbau und

Meerestechnik (Engineering Con- sultants Office for Hydraulic En- gineering and Marine Technol- ogy) will present a new under- water vessel for the installation of submarine cables and pipelines.

The Far East will also make a contribution to this subject: C.M.

Chu of Jao-Tung University in

Shanghai will talk on experimen- tal methods for testing self-pro- pelled underwater craft. E. Wol- lert of DDG Hansa will deliver a paper on how to carry out scien- tific and technical tests of com- ponents onboard a diving vessel.

The last Ship, Machinery, Ma- rine Technology exhibition held in Hamburg in 1978 attracted al- most 25,000 trade visitors from 48 countries. More than 90 per- cent of the exhibitors at that event stated that their expecta- tions had been fulfilled, and every third exhibitor expected follow-up orders.

Every SFC BW unit is equipped with a dedicated feed pump to allow SFC BW

Separators to be sized to meet a vessel's exact needs.

They do not have to rely on the vessel's bilge pump.

Recovered Oil pay-back.

The value of the recovered oil, either returned directly to the ship's fuel tank or stored for reprocessing ashore, should not be overlooked.

The pay-back period for

SFC-BW Separators is continually being reduced as the price of oil rises.

U.S. Coast Guard Approved

Oil/Water Separators

BUTTERWORTH

SFC BW Oil/Water

Separators are now

U.S. Coast Guard approved for shipboard use to meet IMCO and MARPOL regulations for discharge of bilge water.

Under pending legislation all non-tanker vessels over 400 tons which ballast fuel tanks or have machinery spaces, will be required to have a U.S. Coast Guard approved 15 ppm (parts per million) oil/water separator on board to enter U.S. waters. Similar vessels under 400 tons have the added option of transferring oily bilge and ballast slops to a reception facility.

In recent U.S. Coast

Guard certification tests,

BUTTERWORTH* SFC BW (Separator Filter Coalescer-

Bilge Water) units exceeded

U.S.C.G. and IMCO

A.393(X) requirements. In many tests, separated water discharges contained less than 2 ppm of oil. SFC BW units have also been approved in conformance with A.393(X) by Norway. France.

Superior Vertical

Processing.

SFC BW Oil/Water

Separators are simple and rugged, with no internal moving parts. They operate at atmospheric pressure *vith minimum maintenance.

Unlike some other separators. SFC BW units use vertical rather than horizontal processing.

With an SFC BW unit, the oil/water mixture is first introduced into an upper chamber where pure oil is immediately removed. The remaining oily water flows down along an outer shell, then upward past coalescing fins. Final cleansing occurs as the almost oil-free water is drawn through a flushable coalescer medium.

Unaffected by Pitch and Roll.

Unlike horizontal units, vertical processing SFC BW units occupy a minimum of deck space with all separation occurring in a single container.

A 10 cubic meter per hour unit, for example, is only 4% feet in diameter. SFC BW units can operate in almost any weather. They are virtually unaffected by pitch and roll.

Other Features.

With SFC BW units, initial separation occurs at atmospheric pressure. The clean-water discharge pump creates a slight vacuum for final filter separation. As a result, SFC BW Oil/Water

Separators do not clog or stop up. They can be located below the water-line with discharge elevations up to 30 meters.

A standard SFC BW unit operates unattended until a 20-minute filter backflush is required. The time between backflushes - usually 12 to 24 hours - depends on the degree of oil contamination.
