Continuous synopsis record (CSR)

  • Continuous synopsis record is a special measure under SOLAS for enhancing the maritime security at the sea.
  • According to SOLAS chapter I, all passenger andcargo ships of 500 gross-tonnage and above must have a continuous synopsis record on board.
  • The continuous synopsis record provides an onboard record of the history of the ship with respect to the information recorded therein
  • Continuous synopsis record (CSR) is issued by the administration of the ship, which would fly its flag.
Following details should be present in the continuous synopsis record (CSR)
  • Name of the ship
  • The port at which the ship is registered
  • Ship’s identification number
  • Date on which ship was registered with the state
  • Name of the state whose flag the ship is flying
  • Name of registered owner and the registered address
  • Name of registered bareboat charterers and their registered addresses
  • Name of the classification society with which the ship is classed
  • Name of the company, its registered address and the address from where safety management activities are carried out
  • Name of the administration or the contracting government or the recognized organization which has issued the document of compliance, specified in the ISM code, to the company operating the ship.
  • Name of the body which has carried out the audit to issue the document of compliance
  • Name of the administration or the contracting government or the recognized organization which has issued the safety management certificate (SMC) to the ship and the name of the body which has issued the document
  • Name of the administration or the contracting government or the recognized organization which has issued the international ship security certificate, specified in the ISPS code, to the ship and the name of the body which has carried out the verification on the basis of which the certificate was issued
  • The date of expiry of the ship’s registration with the state
  • The continuous synopsis record shall always be kept on board ship and shall be available for inspection all the time.

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.
