BRISTOL, England  Rovco has completed a contract awarded by Well-Safe Solutions to support its well plug and abandonment decommissioning operations in the southern North Sea.

This is the second contract that the company has secured with Well-Safe Solutions, having previously performed survey work on an abandoned subsea wellhead in UK waters in 2021.

During the project, which mobilized in July, Rovco provided Well-Safe Solutions with field survey operations to ensure the safe and efficient decommissioning of a platform, which ceased production in 2015. Earlier this year, Well-Safe Solutions signed an agreement with Ithaca Energy to plug and abandon six wells on the platform. Work being carried out by Well-Safe Solutions will continue into 2023.

Operated by Rovco, the project utilized the VOS Star subsea support vessel, on charter from Vroon, equipped as standard with Seaeye Leopard work-class ROVs, fitted with multi-beam echo sounders, high-quality 4K stereo cameras, manipulators, recovery basket and photogrammetry technology to carry out specialist hydrographic surveys and underwater asset inspections.

As part of the project, Rovco supported the client with debris survey and clearance solutions in water depths of 20 m to 30 m, as well as habitat characterization surveys to mitigate risk and eliminate uncertainty about seabed conditions prior to the client deploying a jackup vessel at the site.

Using its SubSLAM X2 technology, Rovco also performed jacket inspection operations, providing the client with highly detailed 3D models of the platform footings to precisely identify any scouring across the structure. Powered by Rovco’s sister company Vaarst, SubSLAM X2 produces 3D reconstructions of underwater assets in real time, from which users can take measurements with sub-millimetric accuracy. Mounted on an ROV, travelling dynamically at general visual inspection speed, SubSLAM’s ability to zoom in, rotate and fly means it can provide full coverage of a structure from all angles as well as the seabed and surrounding environment.
