Special Requirements
High concentration of 4-bolt hub connectors & Taper-Lok® vendor-specific flanges
Total Connections Managed
55,000+ flanged joints
The construction contractor for the Goliat FPSO required a complete, end-to-end joint integrity assurance solution to support the build of a highly complex offshore asset.
High volume of critical connections
The design incorporated an unusually large number of 4-bolt hub connectors and proprietary Taper-Lok® flanges—each requiring specialist installation, controlled tightening procedures, and rigorous inspection.
Need for full lifecycle traceability
The operator required transparent, traceable records from construction through hook-up and commissioning in the UK.
Manpower expertise
Specialist joint integrity engineers and inspectors were essential to ensure safety, accuracy, and leak-free start-up.
Schedule pressure
Maintaining asset integrity while meeting construction and commissioning deadlines was critical to avoid costly downtime.
In short: the project needed a proven integrity assurance partner with the right software, the right process, and the right people.
Hydratight delivered a fully integrated joint integrity assurance programme built around a combination of specialist personnel and the iDMSâ„¢ joint management system.
Digital Integrity Management with iDMSâ„¢
iDMS was built using original design data and deployed onsite to manage all work scopes.
Joint Integrity Engineers generated detailed work packs and controlled documentation for every connection.
All inspection and tightening data was captured and recorded, creating a live, traceable database for the client.
Specialist Manpower – Engineers & Inspectors
Hydratight Joint Integrity Engineers supervised the work and ensured correct installation and controlled tightening procedures for hub connectors andTaper-Lok flanges.
Joint Integrity Inspectors verified work in the field and updated iDMS with real-time progress and completions.
During hook-up and commissioning, Hydratight personnel built leak test packs and documented verification results, supporting a safe and confident start-up.
Seamless Handover from Yard to Offshore Operations
Because iDMS was used consistently from construction through commissioning, the operator received a fully traceable, structured record of every flange and every activity—ensuring continuity, compliance, and reduced risk.
Hydratight’s integrity assurance programme provided the contractor and operator with:
Controlled tightening and verification significantly reduced leaks at test.
A complete history of every managed connection—from construction through operation.
Competent, trained personnel ensured correct installation and verification on all specialised connectors.
iDMS delivered transparent tracking, progress reporting, and assured handover between construction yard, commissioning teams, and operations.
Verified leak test data gave the client assurance in the completeness and integrity of all work packages.
Hydratight helps operators and EPCs reduce leaks, minimise downtime,
and safeguard personnel with proven joint integrity management
systems and expert manpower.
