Q. State a few amendments caused to IMSBC Code.
The 5th amendment of IMSBC code entered into force on 1st January 2021. The consolidated edition of the International Maritime Solid Bulk Cargoes Code (IMSBC Code), incorporating amendment 05-19, since the IMSBC Code was first adopted in 2008. Several new schedules are introduced. There are the changes in respect of the schedule of coal. Coal as per the amended schedule could be Group A and B unless it is shown to be Group B only by a test. The particle distribution being as follows:
- not more than 10% by weight of particles less than 1 mm ; and
- not more than 50% by weight of particles less than 10 mm.
Two or more coals when blended can form Group A and B. Thus, coal may liquefy if shipped at a moisture content in excess of its transportable moisture limit. Certain group B cargoes (cargoes that possess a chemical hazard which could give rise to a dangerous situation on a vessel) like flue dust, containing lead and zinc; matte containing copper and lead; etc were added to the cargoes for which the Fixed Gas Fire-Extinguishing system (FFEA) may be exempted, when loaded. Bauxite Fines has been added to group A. A corresponding test procedure for determining transportable moisture limit (TML) of Bauxite cargoes is also added. The shipper has responsibility to declare whether a solid bulk cargo is classified as harmful to the marine environment (HME) or non-HME.

The section on mass rescue operations is updated. These amendments are included in the 2019 edition of the manual.
Q. What is the basic philosophy behind the probabilistic concept of subdivision?
Top of Form
Bottom of Form
The philosophy behind the probabilistic concept is that:
- probability of a compartment getting damaged and then the probability that the ship would survive if only that compartment is damaged, as derived from past experience would be a useful information to reach acquired subdivision index;
- two different ships with the same attained index are of equal safety and, therefore, there is no need for special treatment of specific parts of the ship, even if they are able to survive different damages.
Q. Although, the amendments to SOLAS Chapter II-1 had aimed include passenger ships to the probabilistic principle and harmonise cargo ship and passenger ship damage stability, what additional precautions must be taken?
Additionally, the areas in forward and bottom regions, are given special attention in the regulations and dealt with by special subdivision rules provided for cases of collision and grounding. It was found necessary to include a deterministic ‘minor damage’ on top of the probabilistic regulations for passenger ships to avoid ships being designed with unacceptably vulnerable spots in some areas of ship.
Q. What are the SOLAS amendments to Chapter II/1 regarding subdivision, entering into force on 1 January 2020?
The amendments & II/2 entered into force from 1st January 2020. The review has taken into account recommendations arising from the investigation into the 2012 Cost Concordia incident. The amendments aim to ensure increased capability for new passenger ships to remain stable in case of flooding after collision or grounding. A brief summary is as follows:
The changes are made to calculations regarding ‘required subdivision index’ for passenger vessels. Changes are also made in respect of calculating S factor. Limits are introduced regarding the distance between small wells and the keel line unless a damage stability check is made. The minimum limit for the vertical damage extent is introduced. According to the new rules the air pipes terminating in a superstructure will be considered unprotected openings, unless equipped with a watertight means of closure.
The other changes made are in respect of: testing of watertight hatches; permitting a butterfly valve at the collision bulkhead on cargo ships; and ruling out the possibility of leaving watertight doors open.
The revised explanatory notes to Solas II/1 regarding subdivision and stability regulations are also available.
Q. In respect of ‘safe return to port after flooding’, what must be provided to Master of a passenger ship?
For the purpose of providing operational information to the Master for safe return to port after a flooding casualty, passenger ships must have:
- an onboard stability computer; or
- shore-based support, based on the guidelines developed by the Organization.”
Q. What is regulation 20-1 of Chapter II-2?

Q. What is evacuation analysis in respect of passenger ships?
The amendments to SOLAS regulation 13 of chapter II-2 extend beyond RoRo passenger ships, to passenger ships. All new passenger ships carrying more than 36 passengers must be built with evacuation analysis, early in the design process. Thus, the probability of congestion during an abandonment due to normal movement of passengers and crew along escape routes, should be eliminated. There is the possibility that:
- crew may need to move along these routes in a direction opposite to the movement of passengers;
- the escape arrangements must be sufficiently flexible, as certain escape routes, assembly stations, embarkation stations or survival craft may not be available as a result of a casualty.
