DNV 2.7-1 certificates, from the test bed to the owner's portal
Core Inspection runs the DNV-ST-E271 and DNV-ST-E273 workflow for lifting set manufacturers, test houses and inspection bodies: component traceability on the asset, proof load per leg, Certificates of Test and Certificates of Inspection from your own template, and the revision control an ISO/IEC 17025 assessor expects.
- Type approval and batch numbers on the certificate, untyped. Master link, shackles, wire rope, ferrules and thimbles live on the asset record with manufacturer, TA number and batch. The certificate pulls them in, one line per component.
- Proof load per leg, calculated once. WLL, angle and leg count drive the expected test loads for the master link, legs and shackles in kN. The technician records the load cell reading against them.
- Test certificate and periodic inspections on one history. Certificate of Test & Examination at manufacture, then the 12 and 48-month Certificates of Inspection, NDT certificates and anomaly reports on the same lifting set.
- Certificate numbers before the tag is stamped. The number is allocated when the inspection opens, so it goes on the ferrules and the DNV tag before issue, with branch-prefixed series if you run more than one lab.
- ISO/IEC 17025 revision control. Amendments to an issued certificate carry a reason, a revision line and a before-and-after audit, which is what clause 7.8.8 and a NATA or UKAS assessor ask for.
Used by NATA-accredited test laboratories issuing DNV-ST-E271 and E273 certificates
“Core made our report turnaround three times faster while sharply decreasing admin — no more relying on manual methods.”

The owner's as-built dossier, in a portal
Container owners log in to their own register: every lifting set and container, its certificates, NDT reports and next due dates. Unlimited logins.
What DNV certification software has to do
DNV-ST-E271 turns a sling into a data record. Every shackle and link carries a type approval number and a batch, every leg has a proof load, and the same lifting set needs a Certificate of Test & Examination when it is built and a Certificate of Inspection at every 12 and 48-month visit after that, each one citing the certificate before it. Then the container it hangs on has its own plate, its own schedule and its own report.
For a test house or inspection body doing this for many customers, the work is keeping those records straight across thousands of sets while the certificate number has to be stamped on the ferrules before the paperwork issues. Core holds the lifting set as an asset with the component attributes on it, runs both certificates from your own template, keeps the NDT and anomaly reports on the same history, and gives the container owner a portal with the as-built dossier.
What a DNV-ST-E271 certificate looks like out of Core
A sample Certificate of Test & Examination for a new four-leg wire rope lifting set. The layout is the customer's own Word template; the data is the asset and the inspection.
12.5 tonne (MBL 226.8 tonne) at 30°, 2.93 m effective length, 19 mm 4 leg 6x36 IWRC RHOL galvanised grade 1960 wire rope sling with grade 100 master link, machine swaged aluminium ferrules, thimble eye each end, 12 tonne grade 6 safety bow shackles.
- 19 mm 6x36 IWRC RHOL galvanised grade 1960 wire rope, batch WR-7731
- Grade 100 master link 25/19 mm, TA No. TAS0000A12, batch ML-4471
- Aluminium ferrules, batch F-2290
- 12 t grade 6 safety bow shackle, TA No. TAS0000B07, batch S-118 (shackles 1 to 4)
| Master link | 167.9 |
| Leg 1 | 72.7 |
| Leg 2 | 72.8 |
| Leg 3 | 72.7 |
| Leg 4 | 72.9 |
| Shackle 1 | 97.8 |
| Shackle 2 | 97.8 |
| Shackle 3 | 97.8 |
| Shackle 4 | 97.8 |
A load test was applied in accordance with the test specification. After removal of the load each item was inspected by a competent person and found to be free of visible defects. The item complies with the specification.

Traceability lines come from the asset
Each component's manufacturer, size, grade, batch and DNV type approval number is an attribute on the lifting set. The certificate composes one line per component and leaves out any field that is empty.
- 2
Proof loads per leg, in kN
WLL, angle and leg count set the expected test load for the master link, each leg and each shackle. The technician records what the load cell read.
- 3
Your wording, your layout
The specification line, the compliance statement and the footer are your Word template. Core fills the tags; the certificate looks like the one your customers already know.
- 4
Numbered before the tag is stamped
The certificate number is allocated when the inspection opens, so it can be stamped on the ferrules and the DNV tag before the certificate issues.
The DNV-ST-E271 schedule, and what Core does with each line
Sections 8 and 9 of the standard, read the way an inspection body has to run them.
| Requirement | What the standard says | In Core |
|---|---|---|
| Lifting set, 12-month visual (suffix V) | Section 9 requires the complete lifting set to be visually examined at intervals not exceeding 12 months, with the date, inspector's mark and suffix marked in column 1 on the back of the tag. | The lifting set is an asset with a 12-month interval. The Certificate of Inspection renders from the examination, and the tag suffix is a field the technician fills in on the job. |
| Lifting set, 48-month NDT or load test (VN or T) | Components and joining links, and chain legs, get either NDT or a load test at intervals not exceeding 48 months. NDT and visual follow any load test. | MPI, LPI and eddy current certificates and the load test record sit on the same asset as the inspection, so the 48-month evidence is one history rather than three folders. |
| After substantial repair or alteration (T) | The complete set is load tested, then NDT and visually examined, and the container itself may need re-certification by DNV. | A repair job on the asset reopens the test workflow; the new Certificate of Test & Examination references the previous certificate number. |
| Container, 12 and 48 months | Visual every 12 months (V), NDT of the pad eyes plus visual every 48 (VN), lifting test after substantial repair (T), each marked on the inspection plate. | Containers are assets too, with their own intervals, checklist and Certificate of Inspection, and the lifting set linked to the container it is fitted to. |
| Sling certificate contents | Section 8 lists what a sling certificate must show, including the type approval reference and the identification of each component. | Manufacturer, size, grade, batch and TA number for the rope, master link, ferrules, thimbles and each shackle are attributes on the asset. The certificate pulls them in, one line per component. |
| Inspection report contents | Section 9 lists what the periodic report must show, including the date and number of the preceding certificate and who issued it. | The report template reads the previous certificate from the asset history, so the field is filled rather than hunted for. |
Built with two DNV test laboratories
The DNV workflow in Core was shaped by two Australian NATA-accredited labs that issue these certificates every day.
Certex Lifting
Certex Lifting's NATA-accredited test laboratories issue DNV-ST-E271 and DNV-ST-E273 Certificates of Test & Examination and Certificates of Inspection from Core. The component traceability lines on each certificate, with type approval and batch numbers for the master link and every shackle, are composed from the asset record, and the MPI, LPI and eddy current certificates sit on the same equipment history.
Proofload
Proofload's DNV-ST-E271 load test certificate is produced in Core: test procedure, acceptance criteria (AS 1666.2 and DNV-ST-E271 Section 9.3), test bed and load cell, type approval reference, load applied per leg and the asset specification drawn from the equipment record. DNV reviewed the certificate and accepted it for load tests under the standard.

Frequently asked questions
Software that holds offshore containers and their lifting sets as assets with the component data DNV-ST-E271 requires, schedules the 12 and 48-month inspections, captures the test or examination in the field or at the test bed, and produces the Certificate of Test & Examination and the Certificate of Inspection with the contents Sections 8 and 9 of the standard list. For a test house or inspection body it also carries the service side: jobs for many customers, authorised signatories, ISO/IEC 17025 revision control, and a portal each container owner can log into.
