Decommissioning

Your Trusted Partner for Complex
Offshore Decommissioning

Industry Overview

Decommissioning is a vital part of the offshore lifecycle, ensuring that aging subsea assets are safely removed, repurposed, or restored while protecting the marine environment. With increasing regulatory requirements and a growing number of end-of-life fields, operators need precise, efficient, and safe execution across every stage of the process. As scopes become more complex and assets remain buried, corroded, or damaged, the need for advanced subsea mechanical tooling and specialised engineering support has never been higher.

Key Challenges

The industry faces several challenges, including complex removal scopes, difficult access to buried or damaged pipelines and structures, environmental compliance, high vessel and operational costs, and safety risks associated with cutting, lifting, excavation, and dismantling subsea infrastructure. These challenges are amplified by unpredictable seabed conditions, limited visibility, competing schedules, and the need to minimise offshore time to reduce cost and environmental impact.

Unique Group's Expertise in Subsea Decommissioning Operations

Unique Group supports these challenges with an integrated range of subsea mechanical and decommissioning solutions, including cutting and removal systems, mass flow excavation, pipeline and cable recovery, shorepull operations, and specialised back deck equipment. Our capabilities extend further with survey, tracking, and inspection tools that provide precise seabed intelligence, as well as buoyancy, lifting, and mooring solutions that enable controlled recovery and secure handling of heavy assets offshore.

Backed by an in-house engineering department, global assets available for rental and sale, and experienced offshore teams, we deliver safe, predictable, and cost-effective decommissioning campaigns for operators, EPCIs, and marine contractors worldwide. Our customised subsea tooling, environmental sealing systems, specialised clamps, and engineered lifting interfaces help simplify complex scopes and reduce offshore exposure, ensuring greater value and operational continuity across every phase of decommissioning.

Coming to the Middle East 10 years ago

“From a deepwater centric subsea world dominated by Aberdeen, Houston, West Africa, Singapore and Perth I quickly came across Unique in Sharjah. As we have seen across the community here in the region, Unique has been leading the subsea industry from the front and among a select but growing group of local companies in the region focusing on this exciting industry. It’s fantastic to see how the vision and commitment of Harry Gandhi has developed the company into a world player over the last 30 years and good luck to Sahil as he takes the reins. Built around a solid and innovative platform of products and services, the single greatest differentiator is a team of dedicated professionals amongst whom I have professional respect and can count many friends. Good luck for the next 30!”
