Minor Nonconformity and Major Nonconformity

Minor Nonconformity

• Failure to conform to a requirement which (based on judgement and experience) is not likely to result in QMS failure
• A single observed lapse or isolated incident• Minimal risk of nonconforming product or service
• A drawing marked up with unauthorized changes
• A purchase order released without review and approval
• An inspection instrument past its calibration date
• A training record not available
Minor nonconformities have little likelihood of allowing nonconforming product or service to be delivered or causing a breakdown of system control. It does indicate that there are occasional lapses that must be formally addressed through corrective action.
Major Nonconformity
• Total breakdown of system, control, or procedure
• Absence of an ISO 9001 requirement
• A number of minors related to the same clause
• An nonconformity that would result in probable shipment of nonconformity or un-inspected product
• A condition that may result in the failure or materially reduce the usability of product for intended purpose;
• A nonconformity that experience and judgement indicate will likely result in QMS failure or materially reduce its ability to assure controlled processes and products
:• No documented procedure for any required element of the standard
• Document changes routinely carried out in an unauthorized manner
• Critical purchases made from unevaluated suppliers
• Product shipped without required inspection and testsMajors represent serious problems in the system that must be addressed with attention and resources on a priority basis. It puts the business at risk with customers and the Registrar.

Differences between MC/MC-C and ME/ME-C engines

The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators

Why is a man hole door elliptical in shape?

Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole  is lesser in size than the corresponding circular hole. More over it is prime concern to have a  smoothed generous radius at the corners to eliminate stress concentration. Hence other  geometrical shapes like rectangle and square are ruled out.  To compensate for the loss of material in the shell due to opening, a doubler ring has to be  provided around the opening. The thickness of the ring depends on the axis length along the  dirrection in which the stresses are maximum and the thickness of the shell. It is important to  align the minor axis along the length of the vessel, as the stress in this direction is  maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t=  thickness of the shell plating  Circumferential stress: Pd/4t  More over a considerable material and weight saving is achieved as minor is along the  direction of maximum stress.

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation
