Hi Nicole.

Welcome to Planning Planet - a few points.

Please do not liven up old threads - start a new topic and you will get a better response.

Its not a good idea to leave your email in the open forum - there are spammers about.

There have been many discussions on pipelines on PP so search the topic and take your pick.

The main point about linear projects such as pipelines is that you need Time Distance software such as Tilos or Vico or even Asta Powerproject v 12.

Best regards

Mike T.

And I have just noticed that you put the same thread in a different topic - that is a definite breach of etiquette and I will delete them when I find them.

Mr.Sam,

Please send me the list of activities, duration and relationships details through my email-id shafi686@yahoo.co.uk for the cross country piping project.

 

Thanks in advance.

Sanjeev,

Our company involves in pipelying contracting business mostly onshore. Apart from that we also specialise in a front end engineering/conceptual/detail engineering design for gas and /or oil facilities.

Sanjeev I work for a pipeline design company so have done plenty of EPC pipeline project schedules here are some of the items that you may want to consider.

Your eventual schedule will depend on what your pipeline project is. Is it an onshore pipeline or offshore pipeline or both?

For onshore pipelines you will need to consider the construction methodology i.e is it an above ground or below ground pipeline or sections of both. Your schedule should also allow for any shore, road, or river crossings typically HDD is employed these days for this but there are other construction techniques that may be used depending on the situation. Also in your construction schedule you need to allow for pipeline trenching / blasting, clearing the pipeline ROW, pipe handling logistics, trench back filling, set up of pipeline stringing facilities, setup of a construction camp if appropriate, weather downtimes, NDT, field joint coating, end station construction, pipeline flooding guaging and hydrotesting / pre comm and comm.

For offshore pipelines you need to consider the lay methodology S or J lay number of pipelay barges required, pipehaul requirements, vessel mob time, weather down times, setup and laydown, span correction, tie-ins, pipeline stabilisation i.e. rock dumping, trenching or gravity anchor installation. Pipeline flooding gauging and hydrotesting / pre commissioning.

You need to allow for all the procurement and contracting activities including for example, linepipe procurement, coating, flanges, valves, barred tees, pig lauchers & receivers, pipelay / pipeline installation etc.

It is also important to schedule collection of survey data including bathymetric, metocean, geotechnical and pipeline route data before the start of the design activities as this is where many projects get burnt because the data almost always comes late or they base their design on preliminary data and this results in design changes / large variations.

In general I find that pipeline project planning is relatively straight forward compared to offshore platform / plant construction planning as there a lot fewer activities to manage and keep track of and the schedules are generally quite simple due to there only being a handful of procurement and contract packages.
