  1. Industrial Equipment Failures and Construction Disputes

    Leave a Comment

    At Warren, we frequently investigate losses involving industrial machinery.  Many of the losses involve workplace injuries, fires, or explosions; however, we also analyze industrial machinery and processes for other types of problems.  For example, we analyze failures of machinery or industrial processes to perform as expected or disputes that arise from the commercial supply and construction of such systems.  This can encompass a range of issues from failure to achieve required levels of product quality or production quantity, to matters concerning unclear specifications or contracts, (more…)

  2. Interpreting Industrial Incident Data – Lesson Learned

    Leave a Comment

    This is a case study about an incident I investigated involving a major upset in a distillation column.  This blog builds on the previous blogs about the Distributed Control System, DCS – Data is the Key.

    Distillation is a method of separating mixtures of compounds with differing boiling points.  Uncle Bill with his still on the hill separates ethanol, that boils at 173°F, from water that boils at 212°F.  If the mixture is heated to above 173°F, but below 212°F, the ethanol will boil, the vapor will travel up out of the unit and then can be condensed and served over ice with an olive…   Any mixture of two or more chemicals with different boiling points can be separated in this way.  The distillation (more…)

  3. WARREN WEBINAR: Property Claims Issues at Manufacturing Facilities

    Leave a Comment

    LIVE WEBINAR: “Property Claims Issues at Manufacturing Facilities” | Presented by WARREN’s President and Senior Consulting Engineer, Jennifer Morningstar, P.E., CFEI.

    COURSE LEARNING OBJECTIVES
    The learning objectives of this course are to provide the attendees with information on the four major facets of property claims that are commonplace in manufacturing facilities.

    They are:

    1. Subrogation against third parties;
    2. Boiler & machinery vs property claims;
    3. Scope of loss, and
    4. Business interruption

    Each facet will be explored and exemplified by at least one case study.

  4. Forensic Examination of Losses that Include Programmable Logic Controllers (PLC’s)

    Leave a Comment

    Many modern machines and processes are controlled by Programmable Logic Controllers (PLC’s).  PLC’s are essentially computers that have the ability, properly connected and programmed, to interface with the outside world and control the actions of a machine like a robot or conveyor.  The PLC has a processor for processing the user programmed logic, and also has input / output (I/O) wiring provisions for both analog (e.g. temperatures and pressure transducers) and digital (e.g. limit switches and indicator lights) devices.  (more…)
