OSLO, NORWAY — NORWEGIAN CONTINENTAL SHELF & INTERNATIONAL
Specialist engineering for extreme service environments
Independent specialist consultancy in subsea and process integrity, materials engineering, and materials for hydrogen, ammonia and CO₂ service — serving operators, EPC contractors, technology developers and shipowners in Norway and internationally.
Currently taking project-based engagements.
01 — SERVICES
Four problems I get called in for
Engagements usually start with a technical question nobody in-house has the specific background to close out. Each one below ends in a document you can put in front of a regulator, a client or a board.
SERVICE 01
An asset is reaching the end of its design life and you need a defensible case to keep running it
Integrity assessment and life extension for subsea systems — umbilicals, flexible pipes, pipelines, wellheads and structures — and the same method applied to topsides process equipment, including modules being assessed for FPSO redeployment. Condition review, remaining-life evaluation, cathodic protection assessment, and the inspection strategy that supports the conclusion.
WORKED TO
DNV-RP-B401 · NORSOK Y-002 · NORSOK M-001
YOU RECEIVE
Life extension assessment report with stated assumptions, limitations and inspection recommendations.
SERVICE 02
Something failed and you need to know why before it happens again
Failure analysis and root cause investigation on metallic and polymer components in corrosive, high-pressure and high-temperature service. Independent of the supply chain, which matters when the finding has commercial consequences.
COVERS
Corrosion · cracking · degradation · fitness-for-service
YOU RECEIVE
Root cause report with evidence chain, contributing factors and corrective actions.
SERVICE 03
You are moving to hydrogen, ammonia or CO₂ and the materials rules are not settled
Materials selection and integrity for clean fuel and carbon capture service. For hydrogen: embrittlement and compatibility risk. For ammonia: stress corrosion cracking of carbon steel in anhydrous service, and nitriding at high temperature. For CO₂: corrosion driven by impurities in dense and liquid phase, low-temperature toughness during depressurisation, and elastomer and seal decompression. Plus balance-of-plant integrity for maritime fuel cell systems.
APPLICATIONS
H₂ & NH₃ service · CO₂ capture, liquefaction & transport · SOFC balance-of-plant · bunkering
YOU RECEIVE
Materials selection basis, risk register and design review commentary for class or regulator submission.
SERVICE 04
Your process runs outside the range the design codes comfortably cover — at either end
High-temperature creep, thermal cycling and alloy selection where code allowables run out, and low-temperature toughness and brittle fracture risk in refrigerated and liquefied gas service.
FOCUS
Creep · thermal fatigue · high-alloy selection · brittle fracture
YOU RECEIVE
Materials and piping assessment with operating envelope, degradation mechanisms and monitoring recommendations.
02 — ABOUT
David Osborne
Founder & Principal Engineer
I am a materials and integrity specialist with nearly 20 years in extreme service environments — subsea, high-temperature process systems, and emerging clean energy fuels.My career has centred on a single question: how long can this asset safely continue to operate, and what does it need to get there? At Aker Solutions I was Subject Matter Expert for life extension, covering umbilicals, transport systems and structures, and developed the life extension methodology applied across multiple Equinor programmes on the Norwegian Continental Shelf. Before that, seven years at DNV's Technology Centre in Bergen doing failure investigation and condition assessment — the laboratory grounding that still underpins how I approach an integrity problem.A period at Alma Clean Power added ammonia fuel systems and solid oxide fuel cells to that base, working at 650–1000°C. The combination of deep subsea integrity experience and hands-on clean energy materials work is unusual, and it is the ground Hav Integrity is built on.Alongside this I have worked as a volunteer engineer with Engineers Without Borders Norway since 2018 — product specifications for shelter winterisation using locally recycled plastic insulation panels for the IFRC in Turkey and Syria, solid waste management in the Sahrawi refugee camps at Tindouf for UNHCR, and mentoring students building plastic recycling machines to process beach waste in Tanzania. Recycled-polymer work with no material data sheet and no supply chain is a useful discipline to bring back to high-specification engineering.Hav Integrity works directly with operators and engineering companies, and through selected partners where the project warrants it. Based in Oslo, serving the Norwegian Continental Shelf and international clients.

Describe the problem in two paragraphs and I will tell you whether I am the right specialist
No obligation and no proposal process to start with. If it is outside my scope I will say so, and point you at someone it does suit.
