Asset Late Life Services & Decommissioning
At N-ERGISE, we specialise in delivering Asset Late Life Services & Decommissioning globally,
helping operators extend asset life or prepare for safe removal. Safe, cost-effective late life operations during
normal production reduce downtime, cut campaign costs and accelerate decommissioning readiness.

Late Life Services That Protect Schedule, Cost & Safety
Whether you are preparing for an asset to be decommissioned in the near future or aiming to
extend its operational life, N-ERGISE delivers services under live operating conditions.
Starting these activities early helps to reduce maintenance, inspection and engineering costs, while streamlining
your decom timeline. Our multi-disciplined teams steadily complete asset
simplification, deconstruction and weight-shedding operations—cutting offshore campaign days significantly.
Comprehensive Late Life & Decommissioning Services
Delivered by competent teams with robust planning, permits and isolation management—onshore and offshore.
Asset Simplification
- Redundant process & production package removals
- Utility rationalisation and safe isolation/reinstatement
- Waste segregation, manifests and compliant disposal
Asset Integrity & Fabric Maintenance

(see Painting & Specialist Coatings) - Access solutions (rope access, scaffold, MEWP) to minimise POB
- Punch-list clearance and life-extension touch points
Decom Preparation Works – Surveys & Workface Enablement
- Upfront surveys and verification of as-built data
- Weight shedding: removal of non-essential loads, small-bore and ancillaries
- Lifting aid inspection, certification & installation for future heavy lifts
Decom Preparation Works – Scope, Schedule & Cost Studies
- Definition of SIMOPS-safe workpacks and sequences
- Schedule optimisation to reduce offshore campaign days
- Costed options to support AFE and decom strategy gates
DROPS Sweep
- Comprehensive DROPS sweeps across topsides and walk-to-work areas
- Tagging, rectification and verification reports
- Preventative actions embedded into maintenance routines
Our Delivery Approach
- Live-plant execution: robust PTW, isolations and SIMOPS controls
- Multi-discipline teams: mechanical, electrical, fabrication, rigging & lifting
- Documentation: workpacks, risk assessments, lift plans and as-built records
- Logistics & materials: pre-kitted packs to minimise POB and vessel days
HSE & Compliance
Safety is non-negotiable. Our management system is aligned to
ISO 45001:2018.
We operate under UK HSE regulations and EU best practices including
LOLER,
PUWER,
and DROPS principles.
We also align with IAEA nuclear safety standards
and renewable energy regulations.
Benefits of Early Late Life Intervention
- Lower total cost: reduced maintenance/inspection burden ahead of decom
- Fewer vessel days: less time with accommodation/barge alongside
- Schedule certainty: simplified assets enable faster lift & removal
- Risk reduction: fewer SIMOPS conflicts during major campaigns
Where We Operate
We support late life and decommissioning projects across the UKCS & North Sea, North-West Europe, and
project-led deployments globally—including Dubai and the wider Middle East.
Late Life Services – FAQs
Can work be completed during normal operations?
Yes. We execute under live-plant conditions with full PTW, isolations and SIMOPS controls, minimising disruption to production.
When should late life activities begin?
The earlier the better. Early simplification and weight shedding significantly reduce future maintenance costs and decom timelines.
Do you provide lifting aid inspection and installation?
Yes. We survey, certify and install lifting points and aids to de-risk heavy lifts during future decommissioning campaigns.
Do you operate internationally?
Yes. While headquartered in Great Yarmouth, we operate across the UKCS, North Sea, wider Europe, and globally including the Middle East.
