Shipyards have to deliver vessels free from banned hazardous materials (e.g. SOLAS Asbestos ban) and document the location and approximate quantities of a list of defined hazardous materials in what is known as an Inventory of Hazardous Materials (IHM). ACS Marine works internationally with shipyards to ensure supply chains are not infected with banned hazardous materials and offer unique and innovative solutions in IHM preparation.

Inventory of Hazardous Materials (IHM Reporting)

By the end of 2020 all ships weighing over 500GT entering EU ports will be required to carry an IHM.

An IHM is a structured system to control hazardous materials on-board ships and achieve compliance with the EU Ship Recycling Regulation and Hong Kong Convention for the Safe and Environmentally Sound Recycling of Ships. The purpose of the IHM is to minimise risk, avoid potential liabilities, and enhance safety by identifying and recording hazards, and controlling risks on-board.

The kind of materials to be recorded on the IHM are those which have the potential to cause harm to those who are involved in the assets lifecycle; whether that be in the vessels construction, operation or recycling. Examples of the hazards to be recorded within the IHM include Asbestos, Polychlorinated Biphenyls (PCBs), Ozone Depleting Substances (ODS) and Organotin Compounds (TBT).

The requirements for the IHM differ slightly according to if a vessel is under construction, already in service or due to be recycled:

New Build IHM

The IHM for new builds should be developed at the design and construction stage and is based on Material Declarations and Declarations of Conformity from suppliers. ACS Marine will work with the required stakeholders to gather all the required information and conduct random sampling and auditing activities to ensure the information provided is correct and accurate.

ACS Marine will deliver an IHM report which can be used for assurances that the new vessel is free from banned hazardous materials and complies with the required regulations (EU Ship Recycling Regulation, Hong Kong Convention, SOLAS etc.). ACS Marine will also be on hand throughout the assets lifecycle to ensure the IHM is kept up to date and to carry out the mandatory re-inspection survey which is required every five years.

Existing Ships IHM

The IHM for existing ships involves a detailed survey identifying the location and approximate quantities of hazardous materials on-board. ACS Marine’s team of highly skilled operatives will utilise their knowledge of hazardous materials and construction of marine assets to plan, execute and deliver an IHM service which is cost effective, accurate and useful.

ACS Marine is able to offer our IHM survey service for existing ships worldwide and can be conducted during normal operational conditions.

Prior to Recycling IHM

A prior to recycling IHM is required before a vessel can be accepted by the ship recycling facility. ACS Marine will assist in adding the required extra elements to existing IHMs or, if an IHM is absent or sub-standard, conduct a fully intrusive IHM survey.

ACS Marine also offers extensive Ship Recycling Planning and Auditing services to assist marine asset owners who wish to recycle in a sustainable and responsible manner.

Marine and Offshore Asbestos and Hazardous Materials Consultancy

The identification, management and removal of hazardous materials on-board marine and offshore assets is one of the most complex growing requirements for maritime operators across the globe. Whether it be asbestos, PCBs, CFCs, TBTs, toxic heavy metals or even microbiological contaminants such as legionella, operators have a legal duty to protect their staff and customers.

ACS Marine, as part of the ACS Risk Group, has over 35 years of experience in assisting clients in the management of risks related to hazardous materials in a professional, efficient and cost effective manner.

ACS Marine’s Asbestos and Hazardous Materials Consultancy services include:

  • Sampling and Analysis of Suspect Materials
  • Asbestos and Hazardous Materials Surveying
  • Risk Assessment and Control
  • Remediation Project Management
  • Expert Witness, Legal and Dispute Resolution


Supply Chain Assurance

Marine supply chains are complex and a challenge to manage effectively. As a result, banned hazardous materials are continuing to end up on-board vessels which can result in financial and safety consequences. ACS Marine works with suppliers providing expert assistance from engineering and design consulting to assistance with certification and verification, and offering assurance and inspection services to ensure compliance.

ACS Marine find that through having a documented supply chain in which banned hazardous materials are excluded, benefits in terms of quality, cost reduction and down time is achieved for both supplier and customer.
