ROV
DRILL RD40
Cellula Robotics Ltd.
The ROV Drill is a subsea drilling system designed
to take geological core samples of the ocean floor to a depth of 130
feet in water depths of up to 8,000 feet.
- Directed the design of a complex hydraulic
cartridge valve manifold incorporating 5 proportional and 4
directional control valves to control flow and pressure to the
drill pipe drive motor.
- Due to the high flow rate (110 GPM) the
manifold weighs in excess of 200 pounds. The proportional valves
are some of the largest available, but the resulting manifold is
half the weight and a fraction of the size of a comparable one
for sub-plate mounted valves.

U.S. NAVY RESCUE SUBMERSIBLE (Pressurized
Rescue Module)
OceanWorks International Corporation
The Pressurized Rescue Module is a
state-of-the-art submarine rescue system for evacuating the crew
from a disabled military submarine. Total project value: $100
million.
- Lead designer for fluid and gas systems,
supervising other designers and engineers
- Main point of contact for all systems
involving pumps, valves and piping, including high pressure air
and oxygen, dewatering, hydraulic, jettison and emergency
breathing systems
- Designed low profile hull shut off valves for
2-inch dewatering pipes
- Designed modifications to dewatering pumps to
adapt them for subsea use
- Created and supervised test programs for
various systems

DEEP SEA TRAWLING SONAR
Kongsberg
Mesotech Ltd.
These sonars get attached to the
opening of the trawl net, and assist in finding fish and
maintaining ground clearance to avoid damage to the seafloor.
The sonar unit contains a precision mechanical pan-and-tilt
mechanism and sensitive electronics, but is subject to extremely
rough handling when hauled onboard along with tons of fishing
tackle.
- Designed the Sound Dome Mechanics and
Protective Packaging
- Sonar is able to withstand a vertical drop of
1.5 metres onto a steel deck, twice that of the competitors
product

BUBBLE CONTROL VALVE
Submar Systems Inc.
This valve senses water level to
proportionately control air flow into the ballast tank of a two
man wet sub in order to maintain a constant water level in the
soft ballast tank regardless of changing sea pressure.
- Solved problem of dangerous uncontrolled
ascent or descent
- Designed, built and tested the valve
- Extremely sensitive yet handles 200 SCFM air
flow rate
- Compact, simple and cost effective

"GEMINI" SUBMERSIBLE
Hyco Submersibles Ltd.
The Gemini is an acrylic-hulled
(transparent) tourist submersible for eight passengers, with an
operating depth of 2800 ft. seawater (designed but not built).
Supervised design of:
- Special ballast system control and
instrumentation to accommodate for large change in displacement
of acrylic sub due to sea pressure changing with depth
- Life support systems
- Underwater electrical cables
- Special hatch seal for fast tourist entry and
exit
- Solved problem of contraction of a plastic
hull under pressure by having it mounted on slides while still
being held to the frame structure (backbone) of the sub

"DOLPHIN" HATCH
ISE Research Ltd.
Dolphins are diesel-powered remote
controlled semi-submersible vehicles that operate at snorkeling
depth. They were developed for the Canadian Hydrographic Service
and the United States Navy. The hatches for accessing engine and
electronic compartments are saddle-shaped and present a unique
challenge for watertight sealing.
- Designed a sealing system that retains a
pressure tight seal to more than 200 ft of seawater despite
difficult-to-seal configuration
- Designed a fastening system that permits fast
access for servicing the diesel engine. Hatch fasteners have
built in hinges so hatch can be opened from either side of the
vehicle.

"DOLPHIN" DROP WEIGHT
ISE Research Ltd.
Pressure-activated drop weight
ensures that sub will not be lost in the event of a control
failure. Designed, assembled and tested a mechanism that
releases a thousand pound drop weight from the keel of the sub.
- Operated by sea pressure and set to release
at a preset water depth
- Simple and very reliable

SDL DIVER LOCKOUT SUBMERSIBLE REFIT
ISE Research Ltd.
The SDL is a five person (pilot,
co-pilot, diving attendant and two divers) diver lockout
submersible, formerly belonging to the Canadian Navy.
- Designed new gas panels for diver lockout
chamber and life support systems
- Installed stainless steel plumbing on panels
and inside submersible
- Trained submersible pilots and maintainers how
to operate the gas, ballast and hydraulic systems
