• Hydraulic knuckle boom cranes
• Hydraulic A-frames
• Deck-mounted or subsea drum winches
• Hydraulic four-point mooring systems
• Deck-mounted or subsea davits and hydraulic pullers
• Hydraulic traction winches
• Powered reels for ropes, umbilicals and flexibles
• Linear winches
• Hydraulic power units and control systems
• Active heave compensation systems
• Ancillary sheaves, fairleaders, rollers, swivels and hydraulic shackles
• Over-boarding chutes
• Track tensioners

Marine and subsea engineering services

Wale Marine offers engineering assistance for the development of operations procedures and methodologies for diving works and subsea operations, which naturally needs to be developed in parallel with the equipment available or to be engineered and fabricated.

EM control buoy gravity base installation (2000). 100m³ stabilising buoy supplied to SCS by Wale Marine for the controlled lowering of the 3,000Te caisson gravity base.

EM control buoy tether repair (2010). Hanging lower tether (combination air and SAT diving) with in-line tension buoy; installation to gravity base using Rhino 590 HDPE workboat.

EM tether repair (2010): upper tether (air-diving) with in-line 200Te puller being launched for connection between buoy outrigger and tension buoy, for relief of main tether load.

A 300Te hydraulic linear winch system supplied by Wale Marine to Leighton India for onshore pipe pulling during test loading prior to pulling (2008).
