What OWC does

OWC (Offshore Wind Consultants Ltd.) is a UK-headquartered renewable energy consultancy, founded in 2012 by Ian Bonnon and now operating as the renewable energy brand of ABL Group ASA (OSE-listed Norwegian conglomerate). The firm delivers independent technical and commercial advisory services across the full project lifecycle — from early-stage feasibility, site investigation, and permitting, through construction oversight, to asset management and decommissioning — for offshore wind, onshore wind, fixed and floating offshore wind, solar (floating, ground-mounted, rooftop), energy storage, wave & tidal, and hydrogen projects.

Its core technical platform integrates multi-disciplinary expertise in geoscience (geotechnical engineering, geophysics, geohazard risk assessment, ground models, cable geoscience), metocean and wind resource analysis, foundation and WTG engineering, cable consultancy, electrical engineering, and environmental/consents support. This offering is augmented by the Aqualis Geoteam, which combines OWC's geoscientists with sister ABL Group brands (ABL, Longitude, AGR) following the 2020 integration of East Point Geo. Underlying technology stacks are domain-specialised (GIS, geophysical and geotechnical interpretation, integrated loads analysis) rather than software-product oriented.

OWC monetises through professional services on a quote-based, project-by-project basis, with revenue streams spanning Technical Due Diligence, Owner's Engineering, Asset Management, Technical Studies, and Engineering Services. Go-to-market is direct enterprise sales through senior directors and country managers, supported by active participation in industry events (WindEnergy Hamburg, APAC Wind Energy Summit, ONS, Seanergy) and a thought-leadership content engine (white papers, market studies, video library, GWEC-co-developed country guidelines). The firm serves at least five distinct customer segments — renewable developers, investors and financial institutions, government/regulatory bodies, lenders, and asset owners/operators — from 21+ offices across 16+ countries, with a cumulative track record of 330+ offshore wind projects and 100+ GW of offshore wind capacity supported.
