Project Overview
The Agogo Integrated West Hub Development is a major subsea tie-back project offshore Angola. Grispen, working through ERMESYS for SAIPEM, delivered the offshore lifting and rigging design for the field's Production Line Receiver structures, applying the same rigorous DNV-ST-N001 methodology used across our West African PLR portfolio.
The Engineering Challenge
As with all PLR lifting scopes, the engineering challenge centres on managing an irregular structural geometry through a controlled deepwater lift, while ensuring the design package satisfies SAIPEM's internal engineering standards as well as the operator's certifying authority requirements, all within a project schedule tied to a fixed offshore campaign window.
Grispen's Solution
Grispen produced the full lifting and rigging engineering package to DNV-ST-N001, leveraging structural modelling methodology proven on prior PLR projects (including Baleine) to deliver an efficient, high-confidence design within SAIPEM's required timeline. The deliverable integrated seamlessly with SAIPEM's broader installation engineering programme for the Agogo hub.
Scope of Work Delivered
- Offshore lifting and rigging design per DNV-ST-N001
- PLR structural modelling and verification
- Padeye and sling system design
- Lift case load and DAF derivation
- Coordination with SAIPEM installation engineering team
Our Delivery Process
Every Grispen engineering scope, regardless of size or client, passes through the same structured five-stage delivery method, ensuring consistent quality and full traceability from kick-off to final issue.
Agogo reinforces Grispen's track record as a trusted recurring subsea lifting engineering partner to SAIPEM across multiple West African deepwater hub developments, evidence of consistent quality and repeat engagement from a tier-1 EPC contractor.
