The top of the radar mast of the Nisseki Maru is as high as a 22-story building, and she can carry enough oil on a single voyage to fill 180 Olympic swimming pools.

Full-Color Brochure

On Wiring Systems

Six pages of full-color illustrations and accompanying text describe the capabilities of Anixter Wiring Sys- tems, Inc., Aurora, 111., in the fabri- cation of all types of electrical wire and cable products and assemblies.

The output of Anixter Wiring

Systems is classified-in five product groups: wiring harnesses, cable as- semblies, power cords and cord sets, lead wires, and molded plastic and rubber parts. Illustrations show each type of product and the production equipment used in their fabrication.

The facilities of AnixterAViring

Systems occupy nearly 200,000 square feet in four plants, three in Aurora and one in Tipton, Ind. General of- fices are located at 325 South Union

Street, Aurora. The parent company,

Anixter Bros., Inc., has its interna- tional headquarters in Skokie, 111.

The 372,400-dwt Nisseki Maru, the world's largest tanker, was re- cently delivered to the Tokyo

Tanker Co., the tanker division of the Nippon Oil Group, by the Kure

Shipyard of IHI (Ishikawajima-

Harima Heavy Industries Co.,

Ltd.), Japan.

The gigantic s!hip was construct- ed at the No. Two 400,000-dwt ca- pacity building dock at IHI's in- stallation at Kure. The ship is ap- proximately 1,139 feet long, 1/6 as much again as that of the Eiffel

Tower. The top of the radar mast is as high as a 22-story building.

Sixty-three tennis courts could be laid out on the area of the upper deck. The ship can carry approxi- mately 118,800,000 gallons of oil on a single voyage, an amount that would fill 180 Olympic swimming pools. The vessel is about 179 feet wide and 115 feet deep. The 40,000- shp turbine develops a service speed of 14.5 knots.

The Nisseki Maru will be as- signed to the Persian Gulf-Japan route and carry a total of approxi- mately 1,056,000,000 gallons of crude oil in nine voyages yearly to the Nippon Oil Group's Kiire cen- tral terminal station (CTS) in southern Kyushu.

The ship is a fantastic engineer- ing achievement, but it will not be able to boast of being the biggest tanker in the world for long. IHI has two 477,000-dwt tankers on or- der from Gldbtik Tankers Ltd. of

London. Work starts on the first of these in February 1972, also at the Kure Shipyard.

Features of the Nisseki Maru are:

Inert gas system

The inert gas system prevents the vessel's tanks exploding. The system blows inert gas into the ship's oil tanks, full or empty, re- ducing the oxygen density of the air inside the tanks to keep them safe from explosion. The exhaust gas of the vessel's boiler is used as inert gas after it has been cooled and cleaned by seawater, because the gas is too hot and contains some sulfur when it comes straight from the boiler exhaust.

Fixed-type tank cleaning device

In addition to 14 cargo oil tanks and one ballast tank ('seawater tank), the vessel is furnished with two slop tanks for separating oil from water. Fixed-type automatic cleaning equipment has been adopted for the tanks of the ship.

After cleaning, the slop is collect- ed into the slop tanks and separat- ed into oil and water. The clean water alone is discharged out of the vessel, and the oil is kept in the tanks until it is unloaded with the cargo crude oil in port.

Slow speed meter

As the vessel is a large tanker of 372,400 tons, a slow speed meter is provided to measure with the utmost precision the vessel's slight- est movements in all directions, whether they are caused by wind or waves during the vessel's sid- ing, anchoring, leaving, or passing through a narrow water passage, in order to prevent the vessel from grounding or colliding against the dock.

Anti-collision device

New mammoth ships are equip- ped with two radar units. This vessel is furnished with an anti- collision device attached to one ra- dar to automatically warn the crew of any approaching vessel or obsta- cles. This device proves effective on dark nights, in stormy weather, in fog, or in rain.

Centralized control system

The vessel's main engine, boiler, and most of its auxiliary equipment are centrally monitored from the engine control room, and the main stand-by equipment is switched over automatically to function at any time the regular equipment malfunctions. The boiler water lev- el is monitored by TV to prevent any boiler explosion that might oc- cur if the water content is insuffi- cient.
