(5) The Oil Eecord Book shall be kept in such a place as to be readily 

 available for inspection at all reasonable times and. except in the case 

 of unmanned ships under tow. shall be kept on board the ship. It shall 

 be preserved for a period of three years after the last entry has been

 entry in that book and may require the Master of the ship to certify 

 that the copy is a true copy of such entry. Any copy so made which 

 has been certified by the Master of the ship as a true copy of an entry 

 in the ship's Oil Record Book shall be made admissible in any judicial 

 proceedings as evidence of the facts stated in the entry. The inspection 

 of an Oil Record Book and the taking of a certified copy by the com-

 to Side and Bottom Damages 



REGrnLATION 22 



Damage Assumptions 



For the purpose of calculating hypothetical oil outflow froni oil 

 tankers, three dimensions of the extent of damage of a parallelepiped 

 on the side and bottom of the ship are assumed as follows. In the case 

 of bottom damages two conditions are set forth to be applied individ- 

 ually to the stated portions of the oil tanker. 



{a) Side danfiage 



(i) Longitudinal extent (?,0 : For 0.3L from the forward perpendic- 



IS Igss " 



(ii) Transverse extent ( ^^c) : (inboard from the ship's side at right 

 angles to the centreline at the level corresponding to the assigned sum- 

 mer freeboard) B/5 or 11.5 metres, whichever is less.
