The Global Standard for Marine Environmental Protection. The International Convention for the Prevention of Pollution from Ships (MARPOL) is the primary international treaty to prevent pollution from operational or accidental causes. As a fully authorized Recognized Organization (RO), BKI provides end-to-end support across all six technical Annexes—from plan approvals to onboard surveys and certification—so your fleet stays compliant and your operations stay moving worldwide.
Annex I: Prevention of Pollution by Oil
Covers operational measures and accidental discharges related to oil. BKI performs the required surveys and issues the International Oil Pollution Prevention (IOPP) Certificate, approves Shipboard Oil Pollution Emergency Plans (SOPEP), and conducts Condition Assessment Scheme (CAS) enhanced surveys for single-hull oil tankers.
- International Oil Pollution Prevention (IOPP) CertificateSurveys and certification of vessel construction, equipment, and procedures for handling oil and oily water.
- Approval of Shipboard Oil Pollution Emergency Plan (SOPEP)Mandatory spill response plan review and approval for effectiveness and compliance.
- Condition Assessment Scheme (CAS)Enhanced structural surveys for single-hull oil tankers to confirm continued fitness for service.
Annex II: Control of Pollution by Noxious Liquid Substances (NLS)
Sets discharge criteria and control measures for noxious liquid substances carried in bulk. BKI surveys chemical tankers and issues the Noxious Liquid Substances (NLS) Certificate in accordance with the IBC Code.
- Noxious Liquid Substances (NLS) CertificateSurvey and certification for safe handling and transport of NLS in line with the IBC Code.
Annex III: Harmful Substances in Packaged Form
Targets pollution prevention from harmful substances transported in packaged form (e.g., drums, freight containers). Standards cover marking, labeling, documentation, and stowage; compliance is integrated with the International Maritime Dangerous Goods (IMDG) Code.
- ScopeControls on package marking, labeling, documentation, and stowage to minimize loss overboard and pollution risk.
Annex IV: Prevention of Pollution by Sewage
Regulates sewage discharges from ships. BKI surveys installations and issues the International Sewage Pollution Prevention (ISPP) Certificate for approved sewage treatment plants or holding tanks.
- International Sewage Pollution Prevention (ISPP) CertificateVerification of approved sewage systems leading to certification.
Annex V: Prevention of Pollution by Garbage
Addresses garbage management and prohibits discharge of plastics at sea. BKI reviews and approves Garbage Management Plans and verifies correct maintenance of the Garbage Record Book.
- Garbage Management Plan ApprovalReview and approval of shipboard procedures, equipment, and records for compliant garbage handling and disposal.
Annex VI: Prevention of Air Pollution & Energy Efficiency
Limits SOx/NOx and other air pollutants and establishes mandatory energy-efficiency measures to reduce greenhouse gas emissions.
- International Air Pollution Prevention (IAPP) CertificateSurveys and certification of ship and engines against SOx/NOx and other emission standards.
- Engine International Air Pollution Prevention (EIAPP) & NOx Technical FileEngine certification review and NOx Technical File verification, prerequisite to IAPP.
- International Energy Efficiency Certificate (IEEC)Compliance with EEDI for newbuilds and EEXI for existing ships.
- Energy Efficiency Design Index (EEDI) ReviewTwo-stage verification at design and sea-trial phases.
- Ship Energy Efficiency Management Plan (SEEMP) ApprovalReview and approval of SEEMP Parts I–III, supporting CII management.
