New York S N A M E Meeting Hears Paper On Preventive Maintenance

A recent meeting of the New York Metropolitan Section of The Society of Naval Architects and Marine Engineers held at the ABS Building in New York City heard a paper titled, "Preventative Maintenance Programs for Machinery." The author was Richard Rothamel of the American Bureau of Shipping.

Planned maintenance and condition- based maintenance are the two techniques most often used on machinery.

These techniques are frequently used in combination.

Planned maintenance involves the setting of formal schedules for maintenance and overhaul of machinery.

Such schedules are generally established by the machinery manufacturer and include lubrication servicing; filter, bearing, and seal replacements; as well as major overhaul.

Condition-based maintenance plans employ condition-monitoring techniques such as vibration analysis, lube oil analysis, ferrography, shock pulse analysis, and thermography, to determine if maintenance of a particular machine is necessary.

Measurements are taken at periodic intervals.

The American Bureau of Shipping has since 1978 cooperated with vessel owners on developing preventative maintenance techniques as alternatives to traditional maintenance and survey of machinery.

This paper draws from the experience of ABS with vessels involved in these programs, and discusses techniques and key elements used in developing a preventative maintenance program.

The honored guest at this meeting was Helmut (John) Eccarius, who retired from ABS in 1980 as a principal surveyor. He joined the Bureau in 1947 after going to sea and serving as an engineering instructor at the U.S. Merchant Marine Academy. He advanced from surveyor to senior surveyor in 1968, then to principal surveyor in 1970.
