International Convention for the Prevention of Pollution from Ships
What does MARPOL cover?
MARPOL includes regulations aimed at preventing and minimising, both accidental and operational, pollution from ships and currently includes six technical Annexes:
Annex I – Regulations for the Prevention of Pollution by Oil
Annex II – Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk
Annex III – Prevention of Pollution by Harmful Substances Carried in Packaged Form
Annex IV – Prevention of Pollution by Sewage from Ships
Annex V – Prevention of Pollution by Garbage from Ships
Annex VI – Prevention of Air Pollution from Ships
How does Lloyd's Register help?
We are authorised to act on behalf of numerous flag administrations to verify that your vessels comply with MARPOL. Our involvement ranges from initial plan approval and on-board surveys to annual and renewal surveys to ensure compliance is maintained. We are also able to issue type approval certification for marine pollution prevention equipment and sewage treatment plants.
We closely monitor activities at IMO and IACS to enable us to better advise you and keep you up to date with forthcoming changes to the regulations and what they will mean to you. We also offer training courses to help you better understand the requirements.
