Tanker Vessel Environmental Internal Audit Project
Independent technical environmental audit support for tanker vessels, covering MARPOL compliance, pollution prevention, shipboard environmental procedures, records, equipment condition and practical implementation of environmental controls.
Tanker Vessel Environmental Internal Audit Project Overview
The Tanker Vessel Environmental Internal Audit Project is an independent technical assessment designed to evaluate the vessel's environmental compliance arrangements, shipboard practices, environmental records and implementation of applicable pollution prevention controls.
The project examines how environmental requirements are implemented in practice on board the vessel. It combines physical inspection, documentation review, equipment assessment, operational verification and discussion with responsible personnel.
The audit can be adapted to the tanker type, trading profile, equipment configuration, company procedures, previous findings and specific environmental compliance requirements.
Environmental Audit Objectives

Identify Environmental Gaps
Identify deficiencies, inconsistencies, recordkeeping concerns, equipment issues and operational practices that may require corrective attention.
Support Corrective Action
Provide practical findings and priorities to assist vessel management and shipboard personnel with environmental corrective-action planning.

Environmental Compliance & SIRE 2.0 Readiness
Environmental compliance is an important component of overall tanker operational readiness. Environmental equipment, pollution-prevention procedures, records and shipboard practices may be examined during various forms of vessel inspection and assurance activity.
An environmental internal audit can therefore help identify environmental conditions that may require attention before a scheduled tanker inspection, including areas relevant to the vessel's operational readiness.

Tanker Vessel Environmental Internal Audit FAQ
What is a tanker vessel environmental internal audit?
It is an independent technical assessment of a tanker vessel's environmental compliance arrangements, equipment, records, procedures and shipboard environmental practices.
What environmental areas are covered?
Depending on the agreed scope, the audit can cover MARPOL compliance, oil pollution prevention, Oil Record Book, garbage management, sewage, air pollution controls, bunkering, SOPEP arrangements and relevant environmental equipment.
Does the audit include MARPOL compliance?
Yes. Applicable MARPOL requirements form an important part of the environmental audit scope, subject to the vessel's configuration, flag, trading area and agreed assignment.
Is the Oil Record Book reviewed?
Yes. Where included in the agreed scope, Oil Record Book entries can be reviewed together with relevant supporting documentation and shipboard operational practices.
Is garbage management included?
Yes. The audit can review garbage segregation, storage, handling, disposal arrangements, Garbage Record Book practices and implementation of the applicable Garbage Management Plan.
Is the oily water separator inspected?
Where accessible and included in the agreed scope, the oily-water separator and associated pollution-prevention arrangements can be visually and operationally assessed.
Does the audit help with SIRE 2.0 readiness?
Environmental compliance can form part of overall tanker inspection readiness. The audit may therefore help identify environmental issues requiring attention before an inspection. However, the environmental audit is not a SIRE 2.0 inspection and does not replace the formal OCIMF process.
Can the audit be customized for a specific tanker?
Yes. The scope can be adapted according to vessel type, equipment configuration, trading profile, previous findings, location, available access and client requirements.
Is a written environmental audit report provided?
Yes. A structured report can be provided containing observations, findings, supporting information, photographic evidence where applicable and practical corrective-action priorities.
Does the audit provide environmental certification?
No. The project is an independent technical environmental compliance assessment. It does not constitute statutory certification or replace the responsibilities of the vessel owner, operator, flag administration, classification society or other competent authority.
