Explain detainable deficiency with reference to a PSC inspection?

Detainable deficiency:
A deficiency that presents an immediate threat to the ship, its personnel or the environment, which renders the ship unsafe to proceed to sea.

A ship can expect to be detained when in the professional judgment of a PSCO i.e he considered unsafe to allow a ship to proceed to sea before the deficiencies identified have been rectified.

EXAMPLES OF DETAINABLE DEFICIENCIES:
Under SOLAS
  • Failure of main propulsion, electrical, pumping, and steering
  • Excessive oil leakage in E/R, lagging insulation contaminated by oil
  • Absence non-compliance or poor condition of LSA equipment, fire dampers, ventilation dampers, quick closing valves, etc
  • Absence, non-compliance of poor condition of navigational lights, shapes and sounds signals
  • Absence of corrected charts and publications
  • Absence or failure of mandatory navigational systems and equipment
  • Absence or failure of radio communications systems
  • Number, composition or certification of the crew not corresponding to safe manning certificates

Under load lines
  • Insufficient stability or ability to calculate stability conditions
  • Significant areas of damage/corrosion/pitting of deck and hull affecting seaworthiness
  • Absence of poor condition of hull closing devices such as hatch covers and watertight doors
Under MARPOL
  • Absence or poor condition or failure of OWS, ODMCS, and alarms
  • Remaining capacity of slop tanks/sludge tanks insufficient of the intended voyage
  • No oil record book
Under STCW
  • Lack of or insufficient crew member certificates/endorsements
  • Inadequate navigational / engineering watch arrangements/personnel
  • Competency of crew members not adequate for the duties assigned for the safety and security of the ship and prevention of pollution
  • Insufficient rested watchkeepers for the first and relieving watch duties at the commencement of the voyage
Under ILO convention
  • Insufficient food and portable water for the next voyage
  • Excessively unsanitary conditions on board
  • No heating in accommodations if ship operated in low temperatures
  • Excessive garbage blocked passageways


Once the detention order has been placed on a ship, it is likely to remain part of the historical port state records for that ship and be displayed on the web for at least 3 years. A detentions order might include an instruction that the ship has to remain in a particular place or move to an anchorage or other berths. The order should specify the circumstances that would allow the detention to be released The fact that a ship had been detained should be clearly stated on "Report form".

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

Why do we blow through engine before starting ?

The engine is blown through on air before starting it : a) To Blow out through indicator cock any residual exhaust gas or     other products of combustion trapped inside the cylinder after     shutting the engine. b) To check if any jacket cooling water from cylinder head or     turbocharger or any other source, has leaked while the engine          was shut and collected on top of piston. If while blowing                  through, water comes out of indicator cock or relief valve, we          need to investigate and rectify the fault before starting the                engine. It is imperative that the engine is blown through before        starting. There have been cases where the generator engine has        been started from control room without bothering to blow     through first, and water collected on top of piston has resulted in      a bent connecting rod and broken piston.( Reason – water can          not be compressed )

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
