What is Oil Record Book (ORB) & who is required to make the entries in oil record book. What all entries you write in Oil Record Book?


When oil handling work is carried out, the Master, Chief Officer and Chief Engineer shall enter the facts in the Oil Record Book and sign the same according to below procedures.

Every oil tanker of 150 gross tonnage and above and every ship of 400 gross tonnage and above other than an oil tanker shall be provided with an Oil Record Book Part I (Machinery Space Operations).

Keeping Oil Record Book:

The Master shall keep onboard the following Oil Record Books require by laws and regulations

  • Oil Record Book for tankers (cargo and ballast operations) and
  • Oil Record Book for all ships (machinery space operations).
Persons Who Will Sign Entries In Oil Record Book:
  • For oil tankers chief officer and others ships chief engineer
  • Each completed page shall be countersigned by the Master
  • Or the officer in charge of the operation must be the one who signs the entry and it must be done without delay upon completion of the operation, This does not automatically mean the Chief Engineer for engine space operations and the chief officer for oil cargo operations. It should be the officer supervising the operation.
The oil record book part I shall be completed on each occasion, on a tank-to-tank basis if appropriate, whenever any of the following machinery space operations takes place in the space:
  1. ballasting or cleaning of oil fuel tanks;
  2. discharge of dirty ballast or cleaning water from oil fuel tanks;
  3. collection and disposal of oil residues (oil residue (sludge))
  4. discharge overboard or disposal otherwise of bilge water which has accumulated in machinery space;
  5. bunkering of fuel or bulk lubricating oil.

Difference Between A, B & C-Class Divisions?

IMO Symbol A Class Division  IMO Symbol B Class Division  SOLAS has tables for structural fire protection requirement of bulkheads and decks. The requirements depend on the spaces in question and are different for passenger ships and cargo ships. The Administration has required a test of a prototype bulkhead or deck in accordance with the Fire Test Procedures Code to ensure that it meets the above requirements for integrity and temperature rise. Types of Divisions: "A" Class "B" Class "C" Class "A" Class: "A" class divisions are those divisions formed by bulkheads and decks which comply with the following criteria: They are constructed of steel or equivalent material They are suitably stiffened They are constructed as to be capable of preventing the passage of smoke and flame to the end of the one-hour standard fire test. they are insulated with approved non-combustible materials such that the average tempera

Load Line & Why it is Important

Merchant ships have a marking on their hull know as the Plimsoll line or the Plimsoll mark, which indicates the limit until which ships can be loaded with enough cargo, internationally, the Plimsoll line on a ship is officially referred to as the international load line. Every type of ship has a different level of floating and the Plimsoll line on a ship generally varies from one vessel to another.  All vessels of 24 meters and more are required to have this Load line marking at the centre position of the length of summer load water line. There are two types of Load line markings:- Standard Load Line marking – This is applicable to all types of vessels. Timber Load Line Markings – This is applicable to vessels carrying timber cargo. These marks shall be punched on the surface of the hull making it visible even if the ship side paint fades out. The marks shall again be painted with white or yellow colour on a dark background/black on a light background.  The comp

Pump Shaft Alignment Procedure

Types of shaft alignment methods: Visual Line-Up Straightedge/Feeler Gauge Rim and Face Cross Dial Reverse Dial Laser Visual Line-Up The visual line-up method is the most common method of alignment. Used in initial installations, visual line-up allows technicians to analyze the working conditions and feasibility of installation. Straightedge/Feeler Gauge Straightedges are used to determine the offset between coupling halves. Corrections are made under all four of the machines feet. Feeler gauges or taper gauges measure the gap between coupling halves at the bottom and top of the coupling. Rim and Face This method is similar in principle to using a straightedge and feeler gauge, but more accurate since dial indicators are used. The rim reading measures the offset between the coupling halves. The face reading measures the angular difference between the faces of the coupling. Changes are calculated with the same formula as the straightedge/feeler gauge met
