DNV 2.7-1 Testing and Certification
WHAT WE DO
A finished offshore container does not become compliant because it passes one lift test. Certification is built through a controlled sequence: design review, material control, fabrication, inspection, testing and documentation.
That sequence matters most when delivery time is tight. A missing record or inaccessible weld discovered at the end can stop release just as effectively as a physical defect.
Design review sets the basis
The certification route starts with a defined design and an understood container category. If the unit type is still unclear, begin with the three DNV 2.7-1 offshore container categories. The approved basis then needs to remain connected to what is actually fabricated.
Fabrication creates the evidence
Material identity, welding, inspection and non-destructive testing are not activities to reconstruct after the unit is finished. They generate the evidence that the physical container follows the controlled fabrication route. Inspection points should therefore be planned while the relevant areas remain accessible.
Testing verifies a controlled build
The required examinations and tests verify the completed configuration against the applicable certification scope. Testing is important, but it cannot repair a weak fabrication trail. The equipment, markings, inspection records and documentation need to describe the same unit.
The final test is not the main schedule risk
Projects often focus on the visible milestone: the test date. The less visible risk sits in the work leading up to it.
A material certificate can be missing. A weld can become inaccessible before NDT. A fabrication change may not reach the drawing package. An inspection point can be identified after the relevant work is already closed. None of these issues looks dramatic when it first appears, but each can delay certification and release.
The practical solution is to build the certification plan into production. Establish inspection activities before fabrication starts. Keep material and welding records aligned with physical progress. Close deviations while the relevant work is still accessible. Prepare the final documentation as the container is built rather than after it is finished.
This approach also improves the handover into service. Certificates, identification and inspection records form the starting point for the container’s later periodic inspection.
GravityX coordinates engineering, fabrication and compliance activities around the delivery. The aim is simple: when the equipment reaches final testing, certification should be confirming a controlled project — not discovering one.
If the applicable standard is still uncertain, compare DNV 2.7-1 and DNV 2.7-3 before the design is locked.
