This document provides guidance for the management, communication, and maintenance of information in an effective, standardized, and compatible manner in accordance with the requirements of the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships.

This document specifies general inspection and test requirements for liquid hydrogen cargo tanks on board a hydrogen carrier ship. In case of liquefied hydrogen containment system, the testing activity depends strictly on the type of storage technology identified by the IGC code. This document
is applicable to Type C independent metallic double wall type tanks with vacuum insulation having a capacity not more than 1 000 ㎥. It is also applicable to liquid hydrogen cargo tanks which are designed to transport pure para-hydrogen (not less than 95 % content).
Note 1 Annex A gives a general considerations for the liquid hydrogen storage system since liquefied hydrogen has danger characteristics such as low ignition energy, a wide range of flammability limits, low visibility of flames in case of fire, and high flame velocity, which may lead to detonation with shockwave, low temperature and liquefaction or solidification of inert gas and constituents of air which may result in an oxygenenriched atmosphere, high permeability, low viscosity, hydrogen embrittlement including weld metals.

This part of the ISO 28005 series defines the principles and methods for message exchanges between ships, ships' representatives, and shore parties, using this series of standards. This includes the
definition of message structure, including how the data content is assembled from other parts of the ISO 28005 series, and how digital signatures for authentication, integrity and confidentiality of the message shall be used. It also includes specification of basic message exchange patterns and the
responsibilities of each party in the message exchange. Furthermore, it specifies how more specific message implementation guides (MIG) shall be provided for each type of communication application.
Examples of the latter for the maritime single window (MSW) and for mandatory ship reporting systems (MRS) are included in annexes. The specifications in this part are conformant to the requirements in ISO 23807 and uses message exchange and party definitions from IMO FAL.5/Circ.46.

This document specifies requirements for the preparation, execution and reporting of speed trials of ships of the displacement type and provides procedures to be applied in the analysis, evaluation and correction of the gathered speed trial data covering all influences that can be relevant to the individual trial runs reporting of speed trials for ships, with reference to the effects that can have an influence upon the speed, power and propeller shaft speed relationship.

This standard describes generic measuring and calculation methods to evaluate the energy efficiency of multiple components connected in a system called a functional system.
A maritime functional system consists of multiple components. The system is further recognized by integrating multiple functions to achieve an overall goal.
The purpose of this standard is to relate the energy efficiency of various functional systems with other installations onboard of same functionality, thus ensuring that efficient design is rewarded.
Maritime systems are grouped according to their functionality, to compare the energy efficiency of functional systems which could fulfill the same task onboard a ship.
The standard is limited to only include functional systems for which a “unit output” can be clearly defined and which require energy to function.
The standard is mainly covering energy consuming functional systems and is not attempting to provide a lifecycle assessment (LCA). An LCA could prove useful when considering systems that consumes
substances and which would not meet the functional requirements without the use of such; an example could be a ballast water management system using active substances (these types are not considered in this standard).
This version of the standard deals with five types of functional systems:
a. Pressure and flow
b. Lighting
c. Heating/Cooling
d. Mechanical
e. Propulsion
The standard requires specific information about the individual components forming the functional system, the ship and how the functional system will be integrated on board.
The energy efficiency is evaluated using a specified set of global ambient conditions.
