Late liability planning
Closure obligations, surveys and financial exposure become harder to manage when DEP work begins near cessation.

The closure challenge
Decommissioning risk is align to cease operation.
Malaysia’s decommissioning pathway can involve PETRONAS, DOE, marine authorities and multiple legal requirements. Early planning creates space for better options, evidence and cost control.
300+
Malaysian offshore platforms are estimated to be over 40 years old—making responsible end-of-life planning an emerging industry priority.
Fragmented approvals
Different regulators, submissions and project decisions must remain coordinated through a defensible environmental pathway.
Removal and waste uncertainty
Full removal, partial removal or leave-in-situ options require risk-based evaluation, waste planning and clear evidence.
Decommissioning expertise
Environmental assurance across the closure life cycle.
From field-development planning and option selection through dismantling, site clearance and post-project verification.
DEP / ENVIRONMENTAL ASSESSMENT / RISK
Choose a defensible route from cessation to close-out.
Integrate environmental evidence, removal options, risk and regulatory requirements into one practical decommissioning strategy.
- Decommissioning Environmental Plan (DEP)
- Full, partial and leave-in-situ option assessment
- Best Practicable Environmental Option and risk studies
- Regulatory submission and stakeholder coordination
EIA / BASELINE / EMP
Plan closure obligations while options are still open.
Early environmental screening and baseline evidence help asset owners understand constraints before execution decisions are fixed.
- Environmental screening and EIA support
- Baseline marine and terrestrial surveys
- Environmental Management Plan development
- Stakeholder and regulatory engagement support
HSE / WASTE / MONITOR
Keep dismantling work aligned with the approved plan.
Field-focused assurance connects environmental commitments to decontamination, dismantling, transport and site-clearance activities.
- Execution-phase environmental monitoring
- Waste and hazardous-material controls
- HSE performance reporting and compliance audits
- Pollution prevention and incident response
SURVEY / CLOSE / ESG
Verify clearance and document what comes next.
Close-out evidence confirms environmental condition, supports regulatory reporting and identifies any restoration or long-term monitoring need.
- Post-decommissioning environmental surveys
- Site-clearance and closure reporting
- Restoration and long-term monitoring plans
- Resource recovery, carbon and ESG support
Decommissioning outcomes
Make closure decisions with stronger evidence.
Build environmental obligations into the programme early, then maintain control through execution and close-out.
Planned liability
Identify closure obligations, surveys, approvals and environmental cost drivers before cessation.
Defensible option
Compare full removal, partial removal and leave-in-situ choices through risk and environmental assessment evidence.
Controlled execution
Translate the approved plan into practical monitoring, waste, pollution and reporting controls.
Verified close-out
Demonstrate site condition, clearance and any restoration or continuing-monitoring requirement.
Assets approaching closure
End-of-life decisions differ by asset and environment.
EES connects asset context, removal feasibility, environmental sensitivity, waste pathways and stakeholder requirements into a clearer closure strategy.

- 02
Survey & assess
Build baseline evidence and identify environmental, safety, technical and waste risks.
- 03
Select option
Compare removal strategies and prepare the DEP, environmental assessment case and mitigation measures.
- 04
Assure execution
Monitor dismantling, HSE performance, waste, pollution controls and approved commitments.
- 05
Verify close-out
Complete clearance surveys, closure reporting and any restoration or follow-up monitoring.

Why EES for decommissioning
Plan beyond removal to responsible closure.
Early life-cycle thinking
Closure liabilities, evidence and decision gates are considered before options and schedules become constrained.
Malaysia pathway awareness
Practical understanding of the multi-regulator context surrounding Malaysian offshore and industrial closure.
Field-ready controls
Environmental commitments are translated into monitoring, waste, spill and reporting controls for execution teams.
Defensible close-out
Post-decommissioning surveys and closure records demonstrate condition, clearance and continuing obligations.
Common questions
Start decommissioning before options narrow.
Share the asset type, location, life-cycle stage, target cessation date and available environmental information.
Discuss a decommissioning scopeEarly in the asset life cycle. PETRONAS guidance expects decommissioning liabilities and plans to be considered from field development, when surveys, options and funding can still be planned effectively.
Depending on the asset and approvals, assessment may compare full removal, partial removal, artificial-reef potential or leave-in-situ options. Each case needs environmental, safety, technical and economic evidence.
The pathway can involve PETRONAS, the Department of Environment, marine or exclusive-economic-zone authorities and other agencies depending on asset and location. Requirements must be confirmed project by project; this website is not legal advice.
Support can include DEP and EIA preparation, environmental assessment and risk studies, baseline surveys, regulatory coordination, execution monitoring, waste controls, audits, post-decommissioning surveys and closure reporting.
Decommissioning project enquiry
Plan the end before it becomes urgent.
