MarAd Amends Two Research Contracts

The Maritime Administration has executed amendments to research and development contracts with two firms for additional work to be performed for the agency.

Under one of the contracts, Daedleaen Associates, Inc., Woodbine, Md., has been developing an adequate protective covering system for steel propellers in order to replace bronze p r o p e l l e r s, thereby reducing manufacturing and operating costs. The purpose of this second phase of work is to demonstrate the technical and economic feasibility of such propellers.

The amendment covers a final test and evaluation of a large steel propeller protected by a selective covering system. The negotiated price of $882,742 includes the cost of the full-scale propeller.

The other contract—with Mechanical Technology, Inc., Latham, N.Y.—covers the second phase of a three-phase program expected to culminate in the demonstrated operation of improved stern tube bearings and seals for merchant ships. The tasks required under the contract include the performance of immersion, wear, corrosion and endurance tests of candidate seal and bearing materials; fabrication, assembly and checkout of a seal-testing fixture and a bearing-testing fixture; and the design, fabrication and testing of seal and bearing configurations.

The negotiated price is $489,181.
