Coos Bay Towboat Company

Gives Tri-Star Ship

Assist Tug Contract

Coos Bay Towboat Company of

Oregon has awarded a contract to

Tri-Star Marine of Seattle for the construction of a new ship-assist tug.

The 85-foot steel vessel, which will feature twin Ulstein 1650-H Z- drive units, is scheduled for delivery in April of 1994.

Designed by Tri-Star with engi- neering provided by Jensen Mari- time of Seattle, the new tug report- edly will be similar to the Stellar

Wind, which is an 85-foot vessel which was delivered earlier this year to Cook Inlet Tug & Barge of Alaska.

Propulsion for the Coos Bay boat will come from a pair of Caterpillar 3516 diesels, providing 4,000 total hp and an expected speed of about 13 knots.

Hovercraft Used In Cana- dian Gold Mine Construction

Cominco, the mining company, used a hovercraft in the construc- tion of its Snip mine in Canada. The same craft is now in constant use freighting supplies into the area and gold ore concentrate out. The Snip gold mine and mill lies in the Iskut

River Valley a very difficult terrain..

N.Q.E.A. of Cairns, Australia sup- plied the craft, which is a modifica- tion of a standard passenger AP1- 88. The center section of the cabin was removed, a cargo deck fitted and the underfloor and side struc- tures strengthened. Some changes were made for cold weather opera- tion.

During the development phase, the hovercraft carried construction materials and machinery, including small bulldozers. The heaviest load was a 26,000 lb. genset. Now, the

AP1-88 is used to carry fuel and heavy freight into Snip. On the return journey, the craft carries gold ore concentrate downriver. The craft is loaded and unloaded by crane at both ends of the journey. In the warmer months of the year, the craft can maintain a block speed of 45 knots along the Stikene. In winter, drag over the smooth ice falls to near zero, resulting in very high speeds, though ice ridges have to be taken more slowly. The winding

Iskut limits speed to around 20 knots.

Where other systems use nearly 80 modules, the ROX SYSTEM needs only 6 to accommo- date your cable size requirements. Because all you need is the ROX SYSTEM, inventory planning is less complicated and more cost- effective.

The ROX SYSTEM is actually more pliable and offers an easier, more efficient seal than conventional MCT. Plus, the halogen-free rubber is fire resistant and releases no toxins when exposed to flame.

Put the ROX SYSTEM on-board today. Contact NMP Corp. for more information.

ROX SYSTEM • The newest technology in penetration modules • Uses only six (6) different sized module blocks • Provides sealings adapt- able to all cable sizes • Easier installation • Compatible with MCT • The ultimate solution

Give your cable smooth passage by putting it through the ROX.

The ROX SYSTEM takes the lead in transit technology by offering complete adaptability to any cable diameter. The multi-diameter modules (MDMs) offer a simple 'peel-away' system of custom sizing. Simply remove the layered sheets in the center core until the module fits the cable.

U.S. Navy certification of the ROX SYSTEM insures you that it is compatible with MCT and can be installed successfully within the same frame penetration. Because the mod- ules, stayplates and compression systems are intermixable, you can begin using the

ROX SYSTEM immediately.
