The extensive product range includes: Offshore Equipment Handling Systems Pipeline Repair / Recovery Systems Subsea Sealing Systems In addition to product supply Subsea Innovation provides supervision services to oversee the successful deployment and installation of its equipment. The company provides an after care service and can supply spare and replacement parts for the full range of products.

3 Offshore Equipment Handling Systems Subsea Innovation specialises in the design and manufacture of ROV Launch and Recovery Systems (LARS) and bespoke Multi Purpose Handling Systems (MPHS) and has delivered over 80 systems for specialist applications in the offshore oil and gas industries. Launch and Recovery Systems Developed over 25 years with our clients operations in mind Designed to operate in deep waters and to increase the operational weather windows Hydraulically controlled functions including cross/through damp and failsafe docking system Standard proven designs with SWL of 15Te, alternatively client driven bespoke designs Supplied as a stand alone unit or as a system including the TMS, HPU and winch All projects internally managed to EN ISO Quality assurance systems Tether Management Systems An outstanding track record - client still operating units 15 years on Subsea Innovation has a dedicated offshore team available for all your ROV handling equipment needs Successfully operating in depths of 3000m Accommodates tether of 1000m and to diameters of up to 50mm Drum speeds up to 30m/min Standard units with SWL of 15Te Supplied with Subsea Innovation control system or clients specific control system Pushing the operational boundaries without compromising health & safety and our environment Multi-Purpose Handling Systems Ensures safe and controlled tool deployment in higher sea states Designed and built modular for minimal mobilisation time or integrated to the vessel design Active heave compensated main lift line up to 60Te Built in control cabin electronically controlling every function at a touch of a button Total X-Y guide wire movement over all of the moonpool Designed to DNV lifting appliance rules A turn key engineering, procurement and construction ethos

4 Pipeline Repair Systems Subsea Innovation has successful track record of the manufacture and installation of over 20 split sleeve repair clamp systems worldwide since Systems are specifically tailored to individual client projects and eliminate the need for costly pipeline shutdown. Temporary Repair Clamps Provides preliminary leak seal repair to damaged pipeline Up to 5 years service life Prevents product escape whilst permanent repair method is developed Diver / topside installed ROV installed systems can be provided Fast turnaround Pipeline Repair Clamps Leak seal repair of damaged pipelines Designed in accordance with DNV-OS-F101 and DNV-RP-F113 Diver or ROV installed systems available Patented sealing technology provides permanent seal without need for reactivation Successfully installed systems currently operational subsea Structural Repair Clamps Structural support and leak seal repair of damaged pipelines Designed in accordance with DNV-OS-F101 and DNV-RP-F113 Diver or ROV installed systems available Patented sealing technology provides permanent seal without need for reactivation Collet gripping system designed and tested to prove a complete shear of the pipeline can be accommodated Successfully installed systems currently operational subsea Pipeline Connectors Structural connection and sealing of open ended pipeline subsea Generally used in conjunction with a spool piece for large areas of pipeline damage such as anchor drags, where a structural repair clamp is deemed unfeasible Designed in accordance with DNV-OS-F101 and DNV-RP-F113 Diver or ROV installed systems available Patented sealing technology provides permanent seal without need for reactivation Collet gripping system designed and tested to prove full, pressure induced end cap load can be accommodated Design can incorporate client specified end flange for spool connection Successfully installed systems currently operational subsea

5 Subsea Sealing Systems Subsea Innovation design and manufacture an extensive range of standard and bespoke sealing solutions which can be fitted with ROV torque tool receptacles or alternatively ROV hot stabs and receptacles for hydraulic activation. Passive J-Tube Seals Provides subsea seal in bellmouth area allowing corrosion inhibitor to be introduced to the J-Tube Installed topside and activated during the riser pull-in Cost effective alternative to ROV activated J-Tube seal ROV Activated J-Tube Seals Provides subsea seal in bellmouth area allowing corrosion inhibitor to be introduced to the J-Tube Installed topside Seal activated by ROV following pull-in Seal can be reactivated at a later date Diver Installed J-Tube Seals Provides subsea seal in bellmouth area allowing corrosion inhibitor to be introduced to the J-Tube Installed subsea by diver Seal activated by diver operated torque tools Design can be retrofitted to existing risers Riser Hang-off Equipment Provides topside hang-off of riser up to 200 tonnes weight Locking collar or frictional collet system design Sealing system can be installed to prevent product escape into personnel areas of platform Design can accommodate dual direction locking system to account for thermal expansion
