Offshore Retrofit Excellence – MEDAS GmbH & ONGC India Offshore
Introduction
When ONGC India Offshore, one of Asia’s largest offshore oil & gas operators, required a complex retrofit solution to upgrade its offshore operations, it turned to MEDAS GmbH for expertise. The challenge: to deliver 12 high-performance acoustic enclosures in a cost-effective, technically robust, and sustainability-driven manner — without disrupting ongoing operations in a harsh subsea environment.
This case study highlights the technical execution, engineering innovation, and cross-border collaboration that defined the success of this project.
Project Overview
Client: ONGC India Offshore
Sector: Energy – Offshore Oil & Gas
Scope: Offshore retrofit of 12 custom acoustic enclosures and associated systems
Location: India Offshore Fields
MEDAS GmbH Role: Engineering, design, manufacturing, and project execution for delivery of all Acoucstic Enclosures
ONGC faced aging offshore infrastructure that required modernisation to meet new noise, safety, and operational standards. The priority was to improve efficiency and reduce environmental impact while keeping the platform fully operational.
Challenges Identified
Remote & Harsh Environment
Offshore sites presented logistical challenges with high humidity, saltwater corrosion risk, and limited access.Operational Continuity
Retrofit had to be executed without interrupting production.Compliance & Standards
The project needed to meet stringent DNV and ISO standards alongside ONGC-specific requirements.Custom Engineering
Existing infrastructure required tailor-made acoustic enclosures and mounting solutions.
Our Solution
MEDAS GmbH applied a design–engineer–deliver approach:
Advanced Acoustic Engineering
Designed 12 customised noise-reduction enclosures optimised for offshore corrosion resistance and easy maintenance.Modular Retrofit Design
Developed modular sections to simplify transportation and installation.Precision Manufacturing
Fabricated enclosures with marine-grade materials to withstand offshore conditions.Integrated Project Management
Coordinated engineering teams in Germany and India, ensuring seamless alignment with ONGC’s offshore schedules.Sustainability Measures
Selected materials and designs to reduce environmental footprint and extend equipment lifespan.
Key Achievements
12 Enclosures Delivered: All units installed and commissioned successfully offshore.
Zero Downtime: Retrofit completed without interrupting offshore production.
Compliance Success: Fully compliant with offshore safety and environmental regulations.
Impact & Value Delivered
The retrofit not only modernised ONGC’s offshore infrastructure but also improved crew working conditions, reduced maintenance costs, and positioned ONGC as a leader in sustainable offshore operations in the Indian energy sector.
