Description

MBI Global, a Canadian manufacturer of prospection drills, recognized the limitations of traditional hydraulic reservoirs used in their machines. These reservoirs were bulky, heavy, and required a large volume of hydraulic fluid, contributing to increased machine weight, transportation costs, and environmental impact. MBI Global sought a solution that would address these challenges while maintaining the performance and reliability of their drilling equipment. Implementing Smart Reservoir technology resulted in a drastic oil volume and weight reduction which has a direct impact on decarbonization.

Impact & Result

The GT6 drill model is available with a standard atmospheric reservoir of ~200 liters or a sealed-airless smart reservoir of 21 liters providing the same performance. The estimated GHG emitted to produce 200 liters of oil is 275 kg CO2e compared with 29 kg CO2e for the smart reservoir 21 liters. Furthermore, over a 10-year period the standard reservoir which is vented to the atmosphere will require 4 oil changes compared to 2 oils changes with the VVR.

Solution Spotlight

An innovative hydraulic reservoir design where the solution aims to replace in many applications the classic, bulky-heavy tanks. Based on aerospace reservoir design, the concept is affordable and adapted for land & subsea applications. Its prime objective is to get the minimal carbon footprint by its construction, and mainly when filled with hydraulic fluid. Thus, its volume can be 20 times less than a classic reservoir and its weight 100 times less. Its concept is based on a flexible membrane using the commercial name Variable Volume Reservoir (VVR). When filled with fluid, it will compensate for thermal expansion and cylinder rod volume. Over classic reservoir, the VVR offers many benefits; it's light, not flow dependent, and thus can fit with any size pump. It's airless and sealed, eliminating contaminants and moisture ingestion. It can work upside down and even down to the seafloor. Its small size makes it more appealing to fill with bio fluids since these fluids are much more expensive.
