From fall 2004 to fall 2007, I worked with Triton Logging Inc., a Canadian firm specializing in underwater logging. Triton harvests standing timber submerged underwater behind large hydro-dams and other man-made reservoirs using its product line of patented remotely operated vehicles (ROVs) called Sawfish. I was hired into Triton’s design team to help review the company's prototype logging ROV called SF1, and develop a product line of vehicles that improved on almost every aspect of the vehicle.

Working with a small group of two mechanical engineers, two electrical designers and two supervisors, I became intimately familiar with most aspects of the vehicle's design. With all mechanical design being completed in Solidworks, I worked on everything from initial proofs of concept to producing full drawing packages, and then managing many aspects of the vehicle’s build. My major contributions were in the following areas of the vehicle’s design:

Aluminum vehicle structure; completed design and mechanical analysis of vehicle lift-point, tether-entry and tether termination, integral emergency buoyancy, doors and access panels, vehicle front-end and grapple/chain-saw attachment, frames and vehicle skin.

Foam buoyancy; tracked weight and balance of Sawfish over 18 months of design work, researched buoyancy foams, developed software to help with predictions (visual basic and excel), designed foam buoyancy blocks and supervised their construction. Buoyancy prediction was within 30lbs for the first vehicle and within 100lbs for the second vehicle. Both vehicles have in-air weights of ~ 7,200lbs.

Component design; one-atmosphere telemetry canister (unique swing-out design), pressure-compensated high and low voltage junction boxes, hydraulic tilt-camera assembly containing a low light camera as well as two lasers used for range-finding, preliminary design of a complex linear motion assembly used to deliver airbags from the vehicle to a tree, light and camera guards, thruster screens, airbags.

Apart from my role in the mechanical design of Sawfish, I also helped commission vehicles in several remote areas of Western Canada and Malaysia. Platforms consisted of a series of barges, diesel generators, air compressors, electro-hydraulic winches, multiples shipping containers transformed into work spaces, as well as the control booth for Sawfish.
