SMT-ROV Subsea Multi Tool

SMT-ROV Subsea Multi Tool

Combining a DP Multi-Role Vessel and the Subsea Multi-Tool (SMT-ROV) provides the offshore industry with one of the most capable and cost effective ‘one stop’ diverless operations currently available on the market.

We offer versatile deployment methods including; 15-Tonne A-frame launch and recovery system(LARS), with or without an active heave compensated (AHC) winches available, or, vessel crane, tagging tower and constant tension (CT) winch. Boasting a through-frame lift capability of up to 30-Tonnes the SMT-ROV is capable of heavy lift operations using a series of hydraulic tools and can also be transformed into a ‘state of the art’ Survey Skid, which can provide accurate seabed surface and sub-surface imaging for tasks such as UXO, Mattress identification, Depth-of Burial survey, free-span identification, etc.
