ABERDEEN, UK -- EC Harris has a new tool which it says could increase the productivity on the construction and maintenance of an operator’s assets by up to 45% in two to three years. The company is using Offshore Europe to promote the product called Time-on-Tool.
EC Harris says the approach tracks “wrench time” - the actual time that a worker spends performing direct work activities, for example installing a valve or building a scaffold.
“Between 60% - 65% productivity is seen as best-in-class across industry,” says Mark Howard, head of oil and gas at EC Harris. “However, the reality is that actual productivity can be as low as 20% rising to around 40%. Time-on-Tool is a simple but highly effective and accurate way of tracking performance of planned work – how long someone spends doing their job and what prevents them from doing it. By analyzing this we can then look at how those barriers are removed so that productivity can be improved.”
An example of Time-on-Tool in action is on a downstream asset in Louisiana where the operator was able to improve productivity and save money after analysis of the information gathered by Time-on-Tool revealed that 230 contractors were working at 20% productivity. Very quickly, this was reduced to 180 working at productivity levels of around 40%with a continual improvement program initiated to achieve further increases in productivity.
In order to establish a benchmark baseline for improving time on tools, EC Harris also developed a set of man-hour norms – this is the allowance of time for a group of workers to complete routine jobs, such as welding a flange onto a pipe. The norm includes the time it takes to set up at a location, unload materials to do the job, carrying out the job, keeping the area clean, and clearing up once the work is complete.
The man-hour norms apply to all maintenance work, turn-arounds, and project work covering disciplines from mechanical pipework to electrical and instrumentation, scaffolding, insulation, painting, tank repairs, steelworks, rotating/static equipment, civil, HVAC and industrial cleaning.
EC Harris says it has implemented its productivity measurement tool for a number of international oil companies on upstream and downstream assets.
