For maximum safety, sophisti- cated equipment installed includes an intergrated Sperry radar system with ARPA functions and position information connected on-line to the adaptive automatic pilot, and a satellite communications system making possible fast communica- tions via telephone and telex and incorporating a high-speed data link for loading information.

Cargo control instrumentation, featuring a Kockumation Loadmas- ter computer, as well as the ship's safety instrumentation, is located in a separate control room on the star- board side of the superstructure, close to the lifeboats. The location of this control room gives easy ac- cess from cargo compartments and the accommodations area, as well as convenient escape routes in case of an emergency.

Without detracting from the im- portance of the other items of cargo access equipment installed in the

G3s, there is no doubt that MacGre- gor-Navire's weather deck cellguide system, named StackCell™, is the most important advance made in container stowage since the cellular concept was first introduced in the mid-50s. Until now, the biggest drawbacks with fixed weather deck cell guides have been the high weight and the impossibility of uti- lizing them in conjunction with hatch covers. Therefore, all weather deck cell guide systems have until now been mounted marginally above RO/RO spaces and odd deck areas without access to underdeck holds.

Utilizing the MacGregor-Navire side-rolling, piggy-back hatch cover, made possible by incorporating a movable section of the cell guide in the area of the covers, cellular holds

Nos. 1-5 can be loaded and dis- charged through the cell guides on the weather deck.

The twin hatches are fitted with two panels each, and open outboard.

After the inner panel is raised hy- draulically and the outer panel roll- ed beneath it, both are moved out- board in one unit to expose the holds and the cells below.

Another important feature of the

StackCell system on the G3s is the versatility of being able to accom- modate either 20-foot or 40-foot boxes simply by utilizing a movable insert frame that divides a bay into two 20-foot cells, or is positioned at one end of the bay, where its inner face becomes the end of a 40-foot cell. Flexibility is further improved by the frames being only three cells wide, giving four different 20/40- foot ratios each 12-row bay.

ATLANTIC UNIVERSAL

Mitsubishi

The Nagasaki yard of Mitsubishi

Heavy Industries, Ltd., early this year delivered the 570,000-cubic- foot refrigerated cargo ship Atlantic

Universal to Altantic Reefers Lim- ited of Bermuda. Classed by the

American Bureau of Shipping, the new vessel has an overall length of 492 feet, beam of 79.4 feet, depth to upper deck of 49.5 feet, and dead- weight of 12,468 metric tons at a summer draft of about 32.2 feet.

In addition to the most up-to- date energy-conservation equip- ment, the vessel is provided with an effective refrigeration system for transporting a wide variety of frozen cargoes, along with facilities for quick and efficient cargo handling.

She is capable of carrying reefer car- go such as fruit, meat, dairy prod- ucts, and concentrated juice, as well as containers. Her cargo holds are designed to permit temperature control within a range of +12.5 to -30 C.

The cargo space is partitioned into eight temperature-controlled groups, and further partitioned by 'tween decks into 17 ventilated com- partments, each with a cooler room to provide even distribution of cold air.

The weather deck and 'tween decks in the refrigerated cargo holds are provided with MacGregor fold- ing type steel hatch covers. Those on the weather deck are opened and closed by hydraulic cylinders, while those for the cargo holds are by means of wires manipulated by the ship's deck cranes.

The reefer plant has three Stal- built screw compressors (with econ- omizers) using R-22 as primary ©©00, MM?

These, with the compressors, are located on the tank top of the engine room. It is also provided with a brine pump room and brine headers.

An air cooler equipped with a fan for air circulation is fitted on each side of the cargo hold. The ventila- tion frequency of the hold can be selected from 90, 60, or 40 times per hour according to the kind of cargo being carried.

The main propulsion engine of the Atlantic Universal is the newly developed, fuel-conserving Mitsu- bishi/Sulzer 7RTA58 diesel having a maximum continuous rating of 13,440 bhp at 123 rpm. Normal rat- ing is 12,100 bhp at 119 rpm, provid- ing a full-load service speed of 20.1 knots.

The electric power plant is driven by four Daihatsu fuel-efficient die- sels capable of running on fuel of up to 1,500 sec Redwood No. 1 at 38 C.

The ACCU notation of the Ameri- can Bureau of Shipping is applied to the engine room. Not only can nec- essary control and monitoring be achieved from the engine control room, but unmanned operation is also possible through automatic op- eration and control of principal ma- chinery and equipment in the en- gine room.

Other features include: fuel oil purifiers can be operated either in parallel or in series and can also be used as clarifiers; an oil bath type fresh water cooling system is used for the intermediate bearing; jackets and pistons are provided with plate type fresh water coolers; and the cooling sea water piping is made entirely of aluminum brass.
