MHI Bio-Reactor Uses

Bacteria To Convert Oil

Mitsubishi Heavy Industries has discovered bacteria which can de- compose oil to water and carbon dioxide, and has succeeded in the commercialization of a biological emulsion oil treatment system us- ing the bacteria. The MHI Bio-

Reactor, reportedly easy to install and operate, can process fresh or seawater contaminated with oil.

Commercialized to treat the bilge water drained from the ship engine room, the system reportedly reduces oil density of 1,000 ppm waste wa- ter to 5 ppm, below the level re- quired by the marine regulation for oily drainage from the ship.

The oil can even be in the form of an emulsion and be successfully treated since the unit creates its own surfactant. The Bio-Reactor comes in sizes ranging from two through 10 cu. m through-put per day. The system consists of a pre- treatment unit (floating oil separa- tion); bio-reactor (oil decomposi- tion); and after treatment unit (solid and liquid separation). The system developed by MHI uses a ,5-cu.-m bio-reactor and is able to treat 2 cu. m bilge water including 100 ppm concentration of oil per day.

Vela Intl. Selects Nautical

Technology For

Fleet Automation

Vela International Marine Ltd. is installing Nautical Technology

Corp.'s comprehensive ship man- agement microcomputer system,

NTC Ship Manager. The multiple module software will be installed on board 27 of Vela's tankers and shoreside at its Dhahran headquar- ters and five worldwide offices.

Vela will use NTC Ship Manager to cover all shipboard operations and will have it interface directly with its main financial computer system. The system's built-in data exchange capability will help en- sure that all shipboard and shoreside sites share up-to-the- minute information allowing for tighter management control, im- proved procedures and productiv- ity gains. The microcomputer sys- tem consists of program modules which can be installed indepen- dently or integrated with other modules. The modules cover opera- tions such as purchasing, inven- tory control, preventative mainte- nance, maintenance management and service ordering, crew man- agement, crew payroll and commu- nications. NTC Ship Manager will operate on a variety of client/server and network microcomputer envi- ronments as well as on PCs.

Intergraph Offers Integrated

Ship Design And Production

Intergraph is dedicated to inter- active computer graphics, and has been supplying computer graphics

CAD/CAM systems to the shipbuild- ing industry since the late 1970s. In the mid-1980s, the company began to apply its experience in shipbuild- ing to a new generation of hardware and software technology; the result is a suite of products that provide an

Integrated Ship Design and Pro- duction (ISDP) environment.

The Intergraph ISDP environ- ment provides systems and services to support the design, construction, maintenance, overhaul, alteration, repair and refurbishment of ships and shipboard systems.

The IDSP system is built around the concept of the 3D Product Model, where graphics and database at- tributes are integrated to maintain a full associative relationship be- tween all components in the design.
