  1. TM Performance Gearboxes MaxTorque, LLC Marine and Sub-Sea Applications CONTACT INFORMATION: Patrick West, Manager MaxTorque, LLC* EU+31 (0)641755452 North America +1-207-651-1334 *MaxTorque is an Industrial Actuation Group affiliate

  2. MaxTorque Worm Gears – Your Sub Sea Advantage MANUAL, REMOTE OR ROV • Smaller • Gear design allows for greater torque capability in smaller packages • Direct mount allows for reduced head height • 70% base efficiency allows the use of smaller actuators or hand wheels • Faster • Close times 50%+ faster close times • 50% + fewer turns with the same or less input • Lighter • Smaller gear and actuator = less weight • Direct mount capability may eliminate bulky adaptors All images and concepts are property of MaxTorque, LLC

  3. AutoLock (Patent Awarded) TM MaxTorque Worm Gears - a Better Mousetrap Multi-Start, Double Enveloping Worm Gear Set, 4140 HT Standard Sub-Sea Advantages • 200%+ more efficient • 50%+ fewer turns with less rim pull / input torque • Proprietary Self Locking Design • Superior Sealing; O-rings or lip seals at all junctions • Unique sealing system for shallow applications to prevent organic intrusion. • Compensation to 3,000 M Bronze/Ductile Iron Composite 360° Worm Wheel Superior Sealing Options Including Double O-ring Designs and Proprietary Shallow Water Seals All images and concepts are property of MaxTorque, LLC

  4. MaxTorque Worm Gears – Subsea Standard Materials All images and concepts are property of MaxTorque, LLC

  5. How We Do It: Double Enveloping Worm Gear Single Enveloping Worm Gear Double Enveloping Worm Gear Single Start Multi- Start Standard Gears MaxTorque Max tooth contact 2.96 Tooth contact of 6.6 – 10.7 • MaxTorque’s gears: • Multi-start = Faster Close • Greater tooth contact / Double enveloping shape = Higher torque capability and significantly less backlash • Novel tooth shape and high contact ratio = low contact / bending stress leading to superior durability • High helix angle = Superior efficiency (70% +)

  6. MaxTorque – Modular Adaption Modular Direct Mounting Base (Any size, bolt pattern needed) • Modular base plate and drive adaptor • - Direct mount • - Accommodate any top works • - Lower hear height • - 360 degree mounting Splined Adaptor

  7. MaxTorque Compensation, Buckets and Panels • Input Options • - ROV Buckets per API 17D, ISO 13628-8 or as specified • - Horizontal or vertical • - Hand Wheels (Tethered Option) • - Remote or extension drives • General Options • - Panels • - Flush Ports • - Hot Stab • - High Visibility Position Indicators • - Feelicator – Tactile position indicator • - External ROV position indicators All images and concepts are property of MaxTorque, LLC

  8. MaxTorque Compensation, Buckets and Panels • Lubrication • - Oil filled • - Grease filled • - Water soluble • Compensation Systems - Always piston - Passive - Active (Spring assisted) • Special Options • - Check valve position lock • - Input torque clutch • - Bucket extensions • - Special material housings: Carbon steel, duplex • - Special material: nitronic 60, duplex, super duplex input shaft • - Customer specified coating systems All images and concepts are property of MaxTorque, LLC

  9. MaxTorque - Testing / Validation • Sub Sea Testing • Hyperbaric testing at Mohr Engineering, Houston, TX (500 meters) • Hyperbaric testing at Southwest Research Laboratories, San Antonio, TX (1,200 meters) • All units pressure tested prior to shippments • Test Apparatus • Purpose Built • Capable of up to 600,000 ft/lbs • PC / PLC controlled • Calibrated and Validated • Ensures performance and reliability
