General Requirements for a Safe and Efficient Boiler Room

  • Keep the boiler room clean and clear of all unnecessary items.
  •  The boiler room should not beconsidered an all-purpose storage area. 
  • The burner requires proper air circulation in order toprevent incomplete fuel combustion. Use boiler operating log sheets, maintenance records, and the production of carbon monoxide. The boiler room is for the boiler!
  • Ensure that all personnel who operate or maintain the boiler room are properly trained on all
  • equipment, controls, safety devices, and up-to-date operating procedures.
  • Before start-up, ensure that the boiler room is free of all potentially dangerous situations, like flammable materials, mechanical, or physical damage to the boiler or related equipment. 
  • Clear intakes and exhaust vents; check for deterioration and possible leaks.
  • Ensure a thorough inspection by a properly qualified inspector.
  • After any extensive repair or new installation of equipment, make sure a qualified boiler inspector re-inspects the entire system.
  • Monitor all new equipment closely until safety and efficiency are demonstrated.
  • Use boiler operating log sheets, maintenance records, and manufacturer’s recommendations to establish a preventive maintenance schedule based on operating conditions, past maintenance,repair, and replacement that were performed on the equipment.
  • Establish a checklist for proper startup and shutdown of boilers and all related equipment according to manufacturer’s recommendations.
  • Observe equipment extensively before allowing an automating operation system to be used with minimal supervision.
  • Establish a periodic preventive maintenance and safety program that follows manufacturer’srecommendations.

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.

Shell Expansion Plan

It is a two dimensional drawing of a three dimensional surface of the ship’s hull form. This plan is very useful for the following information:It is used for marking the location of a hull Damage on this plan by identifying the strake number , letter and frame number so that the exact location of the damage and also suggested repairs are marked in a localised copy. The shell expansion can be used for finding areas of painting surfaces such as topside, boot topping and bottom areas by applying Simpsons rules directly.  In the shell expansion the vertical scale used is different from the horizontal scale and a suitable adjustment has to be made when calculating areas. This becomes useful in solving disputes concerning areas of preparation and painting. It gives information on the thickness of the original strake which is indicated by the number in the circle shown in the strake.  The quality of steel used is also shown by letters A,B,D E and AH, BH,DH, EH.
