New technology centres bring next generation testing services to the industry
In October 2016, DNV GL moved and opened new laboratories, located easily accessible close to the city centre of Bergen:
- Technology Centre for Offshore Mooring and Lifting at Buehallene
- Materials and Corrosion Technology Centre at Marineholmen.
The material expertise, laboratory examination and testing capability, are providing confidence in cost-effective and safe solutions. The Materials and Corrosion Technology Centre at Marineholmen is dedicated to investigating failures and testing materials characteristics and performance with respect to corrosion resistance.
Working closely with DNV GL laboratories at Høvik and around the world, our Bergen laboratories are uniquely suited to support customers operating internationally, on the Norwegian Continental Shelf and locally at yards or bases along the coast.
Our technology centres offer a unique combination of testing, analysis and theoretical expertise. Services range from facilitation and optimization of test programmes, to standardized mechanical tests and full-scale simulated service tests within these areas:
- Large-scale testing, specifically for offshore mooring and lifting
- Coating testing
- Corrosion testing with excellent H2S capability
- Failure investigation and root cause analysis.
Large-scale testing comprises capabilities for both standardized and tailored qualification and verification testing of fibre ropes, mooring chains, steel wires, and other components such as lifting accessories and oilfield risers. The biggest machine has a 2,900 ton load capacity (28500 kN) for static and dynamic testing and can test samples up to 20 meters length. The equipment upgrade and lengthening of the machine in 2017 enables testing of large dimension fibre ropes that are being used in deepwater fields today. Wire rope testing can be done on short notice to provide immediate and timely results. To expand the large scale-testing capability, DNV GL is now defining and setting up a test rig for analyzing the effects that ropes are experiencing when running over sheave (cyclic bending over sheave) as in heave compensation for subsea lifting. Capability expected to be operational in 2017/2018.
Coating and corrosion testing with unique H2S capability
Our services cover general and localized corrosion, coating degradation, materials compatibility, stress corrosion cracking, corrosion fatigue, thermal fatigue, creep, high-temperature corrosion, microbiologically-influenced corrosion, and fracture mechanics.
The laboratory has improved capacity to expose samples safely to H2S for qualifying materials for service in sour environments, an issue in many challenging oil and gas fields.
The laboratory holds accreditation for:
- Performance Standard for Protective Coatings for Cargo Oil Tanks of Crude Oil Carriers systems in accordance with IMO Res MSC.288(87)
- Performance Standard for Protective Coatings for Dedicated Seawater Ballast Tanks in accordance with IMO MSC.215(82)
- Accreditation for ISO17025 is ongoing and expected to be in place in 2017.
Failure investigations and identifying root causes
Our laboratories in Bergen have a long history of failure investigations providing a valuable basis for internal and external learning. Many of the investigations benefit from our expert system knowledge of ship machinery, subsea, pipelines, mooring systems and structures.
We have an advanced metallographic facility with cutting, mounting, grinding and polishing equipment, and carry out full-scale materials analysis using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and physical testing (hardness, grain size, optical photography).
