Offshore Installation Services Ltd (OIS), an Acteon company, provide integrated project management services specialising in vessel-based subsea installation and decommissioning projects. OIS has an unrivalled track record in the successful abandonment of suspended wells and has completed over 100 projects since 1996 in the UKCS. OIS specialise in multi-operator decommissioning campaigns which enable operators to share project costs and ensure a cost-effective way to decommission non-revenue generating assets and comply with UK oil and gas legislation when compared with a rig based alternative. As part of the Acteon Group we have access to the collective experience of our sister companies whose activities span the spectrum of subsea services and cover the world�s major operating hubs.
