Marinette Marine Delivers

Last Of 52 Workboats

A Year Ahead Of Schedule

Marinette Marine Corporation's contract with the Naval Sea Sys- tems Command for fifty-two 50-foot workboats was completed one year ahead of contract schedule when the last workboat departed the Wiscon- sin-based shipyard in December of 1985 for delivery to the West Coast.

One vessel per week has been deliv- ered to the East and West Coasts since November 2, 1984.

The original contract for 28 ves- sels was awarded to Marinette Ma- rine in February 1984, and an option contract for 24 additional vessels was awarded in November 1984.

The workboats are of steel construc- tion with an overall length of 50 feet, a beam of 14 feet 4 inches, and a full load draft of 3 feet 6 inches.

The twin-screw craft is powered by a pair of 8V-71 GM engines.

Marinette Marine Corporation, now in its 43rd year of operation, is a company of marine design engi- neers and shipbuilders specializing in the design and construction of defense related marine vessels, and high technology commercial craft.

Copper Blast would like to dust off your blasting budget.

Dust (shown here from silica sand) means lower cutting efficiency and visibility and increased health hazards and clean-up costs.

COPPER BLAST (in use here) has very little dust, is low in free silica, cuts 30-50% better than lower-quality slag abrasives and up to four times better than many silica sands.

We can tell you how much the dust in your present abrasive is costing and how much you can save by using COPPER BLAST.

COPPER BLAST is a low free silica, low dust abrasive with a 30%-50% cutting advantage over lower-quality slags. It cuts up to four times faster than many silica sands. With COPPER

BLAST, job time goes down and cost effectiveness goes up.

The first step could be our COPPER BLAST Value Worksheet.

Using your project figures, you can see how much dust particles — which do no work! — are costing you. We'll also show you how COPPER BLAST can save time and money on your jobs plus the results of laboratory tests on several kinds of abrasives.

COPPER BLAST is manufactured in a new, high-tech plant and adequate supplies are always available throughout the West and Midwest.

For your COPPER BLAST Value Worksheet, or for more infor- mation, call or write James D. Hansink, Manager, Construction

Materials, Rocky Mountain Energy, 10 Longs Peak Drive,

A. L. Don introduces the 'Next Step' in debarkation ladders... "ERIKII"

Erik II" is a totally synthetic embarkation/debarkation ladder. This new and unique ladder is designed with steps you can replace quickly and easily, right on board the vessel.

A specially designed mechanical clamp holds each step in place. So there is no need to unstring the ladder and there are no special tools required.

Erik H" has successfully undergone drop tests as high as 95' (28.96 meters).. .the longest length synthetic debarkation ladder ever approved by the U.S.C.G. and meets or exceeds

SOLAS and IMO standards as well. Each step will easily with- stand loads of 700 lbs. with less than %" of deflection. The ropes are polypro-dacron with a white outer jacket and orange inner safety core. "Erik II" is patented, available worldwide, and at prices far lower than those of competitors.
