Subsea Bullseye Slope Indicators

The I-TECH Subsea Bullseye provides an accurate, cost effective solution for monitoring inclination Subsea. 

When calibrated to a subsea structure the bullseye gives a true reading of inclination, to an accuracy of roughly 0.25 degrees. The highly visible reading area allows bullseye readings to be easily taken by divers or camera systems.  A unique domed viewing area reduces silt build up, minimizing the need for cleaning and maintenance. The all-polymer design is strong, lightweight , and designed not to degrade in salt water. Units are type tested to a depth of over 6000m (20,000ft) ensuring functionality for deep-water applications. 

Get Started:

Bullseyes are available in a variety of sizes and angle tolerances, and can be mounted on the mounting system that suits your requirements.

The I-TECH slope indicator tackles the complex problem of product leveling in a sub sea environment with an innovative and simple solution that has no costly or failure prone electrical components — it instead relies on simple mechanics, and some advanced mathematics and engineering. 

Traceability -- Each slope indicator has a unique identification number which in turn relates to a batch number. This gives us complete process trace from start to finish of each batch of slope indicators.

Testing -- Slope indicators are type tested annually to depths of 18,000 feet by an independent testing house. Random profile and finish testing by an independent registered testing establishment. Each slope indicator is subject to our own rigorous in house inspection and inclinometer tests.

Sealed -- Each slope indicator is completely sealed from any outside environment via its completely sealed acrylic construction. The filling plug is torqued and encapsulated in tensol 12 cement to ensure a total seal.

Construction -- The I-Techs unique all acrylic construction allows us to keep the overall weight of a unit to approximately 8.5kg. By using innovative engineering techniques we are able to eliminate the use of failure prone electronic components in the unit's construction.

Bubbles -- Each slope unit is checked for bubbles before transportation. An allowable bubble of up to 12.7mm diameter is acceptable and will not affect the unit's performance. This is the industry standard for such products. No unit leaves our factory with bubbles present.

Standards
The I-Tech works to the BS EN 9001 : 2000 Quality Management System standard.

Applications
The I-Tech can be used in a variety of sub sea applications. These are typically: Pipelines, Habitats, Manifolds and Christmas Trees. Each slope indicator is designed to withstand the pressures generated at 20,000ft sub sea. This is achieved via its domed construction and pressure equalized fluid interior.

Warranty

We offer a 12 month warranty on our ClearView™ I-TECH Slope Indictors and mounting systems from date of purchase on all manufacturing faults providing the parts have been maintained and stored as per our data sheet. Terms and conditions apply.
