DSVi Diving Services Frame Agreement

The DSVi collective is made up of a group of operators namely, Chevron, Dana, Hess, Nexen, Talisman Sinopec and TAQA who, through a collaborative arrangement, benefit from continuity of access to a Dive Support Vessel. This allows the operators to benefit from cost sharing and dedicated long-term project support.

This arrangement - which has been in place since 2009 - sees Subsea 7 provide Diving Support Vessel (DSV) services on a year-round basis, as well as associated project management and engineering services to over 40 North Sea facilities. This long-term relationship recognises the importance of Subsea 7’s flexible and collaborative approach in delivering services to a multi-client customer.

OverviewSubsea 7 has been providing inspection, maintenance and repair services to the DSVi collective since 2009 through to 2015 and under the current contract from 2016.

The DSVi scope covers:

• Provision of routine and non-routine diver and ROV inspection, repair and maintenance to over 40 DSVi collective facilities in the North Sea

• Tie-ins of newly installed step out and manifold wells and other project work as required

• Design and fabrication of spools and structures

• Subsea construction and decommissioning services

• Diver and ROV inspection services

• Project management and engineering services

• Provision of qualified onshore and offshore personnel

• Provision of additional third party personnel and equipment e.g. ROV support vessels, RIB diving support vessels, ad-hoc platform based diving/ ROVs, tugs/ supply vessels and commissioning services.

Work is primarily carried out using Subsea 7's fleet of Dive Support Vessels along with access to Subsea 7’s fleet of ROV and Construction Vessels as required.

By developing a programme of work for all DSVi clients and various geographical locations, efficiencies are gained both operationally and financially. Further value is gained through the collective's access to Subsea 7’s wide range of subsea engineering support disciplines, such as design, fabrication, pipeline, survey, and remote intervention.
