Shipbuilding

Shipbuilding involves the design and construction of complex vessels operating in demanding marine environments, with strict regulatory, safety, and classification requirements. Projects require close control of materials, fabrication quality, and system integration across extended build programmes.
We support shipbuilding projects through independent inspections, vendor assessments, and quality assurance services. Our oversight helps manage construction risk, ensure compliance with classification and contractual requirements, and support reliable vessel delivery.

Heavy Industrial Fabrication

Heavy industrial fabrication underpins large‑scale infrastructure and energy projects, involving structural steelwork, pressure systems, and complex assemblies. Quality, traceability, and workmanship are critical, particularly where components operate under high loads or extreme conditions.
We support heavy industrial fabrication through inspections, vendor assessments, and manufacturing surveillance services. Our independent assurance helps clients manage quality risk and ensure fabricated components meet technical, safety, and regulatory requirements.

Industrial & Marine Sectors

Supporting Asset Integrity Across Global Operations

The industrial and marine sectors support some of the world’s most complex infrastructure, manufacturing, and transportation projects. From heavy industrial facilities and shipbuilding programmes to offshore structures and marine engineering, these environments demand strict quality control, safety compliance, and reliable supply chain performance. Projects often involve global suppliers, specialist fabrication, harsh operating conditions, and critical timelines where technical assurance is essential.

At SQS, we provide independent inspection, expediting, vendor assessment, and quality assurance services that help clients manage risk across industrial and marine supply chains. Our global network of inspectors supports projects throughout fabrication, construction, installation, commissioning, operation, and decommissioning - helping ensure equipment, materials, and processes meet project specifications, international standards, and operational requirements.

ABOUT SQS

Marine Fabrication Yards

Marine fabrication yards deliver major offshore and coastal structures, often operating to tight schedules and working with large, high‑value assemblies. Projects typically involve complex welding, coatings, lifting operations, and interface management.
We support marine fabrication yards with independent inspections and quality assurance services across fabrication, assembly, and load‑out activities. Our oversight helps manage workmanship, compliance, and programme risk in challenging marine environments.

Subsea & Offshore Structures

Subsea and offshore structures operate in some of the most extreme environments, requiring robust design, precise fabrication, and rigorous quality control. Failure risks are high, with limited access once installed and significant safety and environmental implications.
We support subsea and offshore projects through inspections, vendor assessments, and quality assurance services across fabrication, testing, and installation preparation. Our independent oversight helps ensure compliance, integrity, and long‑term asset performance..

Large‑Scale Mechanical & Process Equipment

Large‑scale mechanical and process equipment is central to industrial plants, energy facilities, and infrastructure projects, often involving bespoke design and long lead times. Performance, reliability, and compliance are critical, as failures can impact safety and operations.
We support clients through inspections, vendor assessments, and manufacturing surveillance for large and complex equipment. Our services help manage technical risk, verify quality, and support on‑time, compliant delivery.

Ports & Maritime Infrastructure

Ports and maritime infrastructure enable global trade and offshore activity, integrating civil, mechanical, electrical, and marine systems. Assets must remain resilient under heavy use, harsh environments, and evolving regulatory requirements.
We support ports and maritime infrastructure projects with inspections, vendor assessments, and quality assurance services across construction, upgrades, and maintenance. Our independent oversight helps manage risk, support compliance, and protect long‑term asset performance.
