Non-transferable travel tickets – 25% saving in annual travel budget

An operator in the oil and gas industry noticed that there were inefficiencies in their internal travel system. A short desktop exercise highlighted that the organisation was hugely inefficient when it came to booking flights – incurring costs for fight transfers, name changes and last minute cancellations.

The operator decided to trial booking non-refundable tickets instead. All employees must travel on the train, plane or car they had booked and could not be transferred.

This small change has resulted in a 25% cost saving in travel across the entire company. This also would have reduced the carbon footprint for the organisation overall.

A spokesperson for the company said, ‘it is amazing how one small change like this makes such a big difference. If a person needs to change their flight it is escalated all the way to the top for approval – so everyone here has changed their mindset to ask themselves if they really need to travel, and when. It’s a personal ownership of being more efficient. It makes sense.’

Carbon efficiency – Gas turbine routine fuel changeovers

Glen Lyon has 4 gas turbines which typically run of fuel gas to provide electrical power to the plant. Each turbine is duel fuel meaning they can also operate on diesel.

In order to check this duel fuel facility each unit is run on diesel for four hours each month. This is to perform a number of key performance checks while on a liquid fuel. The Glen Lyon team identified that these checks could be performed in 15 minutes. Reducing the duration of diesel combustion by 3.75 hours. This change gas now been formalized on the FPSO and lessons shared with other BP assets for implementation where possible.

Cost Saving = £51,700 in Carbon + £855,000 in diesel
Diesel saving = 1710 M3/yr
Total CO2 saving= 2048 TCO2/yr
FuelHoursCO2 per testCO2 per year
Total Saving2048

By replacing diesel combustion with Gas combustion the mass of CO2 is reduced as per tonne, diesel emits more CO2 than Gas. Further more Gas has a higher energy value so less gas needs to be burnt to generate the same power as diesel

In addition to Carbon and diesel savings, this change prevent the turbine burners being choked up so quickly and make efficiency savings through not having to needlessly replace the burners, changeout diesel filters and time saving within the electrical technician’s week.

This improvement was Identified and executed through BP’s Challenge , Check and Change initiative

Atkins – Maximising your Plant Capability using MeasCap

1. Problem Statement

In the oil and gas industry things don’t stand still. You may want to introduce new wells onto your facility, or rationalise your gas plant for declined production. Traditional capacity reviews work on one production profile case at a time, so become very time consuming and expensive when dealing with uncertainty and evaluating a number of options. Atkins’ MeasCap tool has been tailor-made to provide a more efficient approach to capacity assessment

2. Aims

For over 10 years, Atkins has been optimising our in-house software tool, MeasCap, to make facility capacity assessment:

  • Fast: automation allows hundreds of cases to be run/re-run in minutes
  • Extensive: multiple cases can be run simultaneously, allowing the full potential production envelope / field life to be assessed
  • Adaptable: easily incorporating late / future changes in data
  • Trustworthy: auditable, checkable, verifiable results
  • Results-focused: providing user with clear results and upgrade options

3. Method

Automated assessment of cases, which can be used to identify  capacity limitations, and then rerun to understand debottlenecking option effectiveness. The options are then assessed by our engineering team to understand constructability and cost implications, and option comparison. The flexibility offered by MeasCap allows late data to be incorporated, and the model can be re-used for future studies.

4. Impact

MeasCap has been used to help our clients assess a number of scenarios, including:

  • Third party tie-backs
  • Addition of new wells
  • Life of field studies
  • Low pressure operation options for maintaining export pressure
  • FPSO redeployment
  • Facility rationalization for late life
  • Terminal debottlenecking

The automation of cases makes the process far more efficient, and allows our  engineers to work with our clients to focus on assessing the “what if” questions. Clear results are presented which show the bottlenecks on the plant and feasible operating envelope, and display the range of opportunities available, with option payback vs investment cost.

Efficiency improvements

Automated capacity assessment gives double the results in half the time

Total savings anticipated

Typical study reduced from 12 to 6 weeks, saving > £30k

MeasCap has been used effectively on a broad range of offshore/onshore facilities, and was shortlisted for the IChemE Core Chemical Engineering Awards 2013
