IACS Position Papers

IACS “Position Papers” are issued and reviewed regularly by IACS on key topics for the Industry. These position papers provide background to the subject matter, IACS position on the subject and summary of actions that IACS has taken.

Ballast water management

IACS will, within the IMO framework, contribute to developing practical measures and seeking globally consistent implementation of the BWM Convention during the Experience Building Phase that was established to develop improvements to the Convention. IACS also consider that technical challenges with regard to retrofit, engineering, potential safety implications and efficient surveys on-board are to be identified and adequately addressed firstly in IMO instruments or otherwise in IACS resolutions. 

Cyber Systems

Cyber incidents on vessels can have a direct and detrimental impact on life, property, and the environment. IACS has steadily increased its focus on the reliability and functional effectiveness of onboard, safety critical, computer-based systems. 


IACS will implement a structured, systematic and uniform approach in the compilation, management and application of reliable, traceable and retrievable data in all its work.

Digitalisation and Connectivity

IACS supports the use of electronic certificates (E-Certificates). IACS intends to contribute to development of any practical measures to amend the IMO guidelines for use of electronic certificates.


IACS holds the position that the scheme for monitoring, reporting and verification (EU MRV) of GHG emissions from shipping should be technically credible and aligned as far as possible with the internationally agreed scheme. In practical terms this means that an IMO developed scheme is IACS’ preferred option.

GHG emission reduction targets

The IMO goal-based regulations are the appropriate means to address GHG reduction measures globally, and IACS will assist in developing practical detail requirements and assist in implementation of proposed technical measures.


The advancement of Maritime Autonomous Surface Ships (MASS) has reinforced future trends of autonomy and the need of improved technical requirements in shipping. IACS intends to contribute to MASS through its involvement in various fora, reinforced by its maritime technical expertise, and as a trusted partner to regulators and industry.

Sulphur Cap 2020

Design and operational aspects associated with the new compliant fuels have to be addressed well before the January 2020 implementation date of the lowsulphur requirements. Potential safety implications (stability of blended fuel oil, compatibility including new tests and metrics appropriate for future fuels, cold flow properties, acid number, flash point, ignition quality and cat fines) were identified during the PPR intercessional meeting (ISWG-AP 1) with actions being taken to address them. Provided the actions are appropriately addressed by 01 January 2020, we consider the information will be in place to allow the major technical challenges to be addressed. 

Underwater Noise Pollution 

IACS shares the concern about underwater noise from commercial shipping expressed in MEPC 75/14. IACS has the view that IMO is the appropriate and technically competent body to address the mitigation of underwater noise from commercial shipping globally but is working to harmonize measurement procedures.
