Pipeline Pigging Technology

Insurance

This may differ from country to country, but basically:

client and contractor are responsible for insuring their own equipment
during the survey;
client and contractor indemnify each other for damage brought upon
the other;
client and contractor refrain from claiming consequential losses.

In addition to these standard service-contract insurance requirements, the
client will remain responsible for damage to the inspection pigs as the result
of incorrect operation of the pipeline system.

Responsibilities

The contractor is responsible for preparation of the equipment to the
specifications required for the job (unique for each pipeline), and for
providing the equipment in a "fit-for-purpose" condition to the job site (a final
pre-survey test is carried out on site).
The client is responsible for handling the equipment on site and running
it in the pipeline in accordance with pre-agreed conditions (flow, pressure,
temperature and pipe wall surface condition). Repairs to the contractor's
equipment, other than normal wear and tear, will be charged to the client.
Re-runs as a result of the contractor's fault will be provided free of charge,
for which the client will make available the pipeline and provide all contrac-
tually-agreed conditions.
Re-runs as a result of the client's fault will be charged at the pre-agreed
rates.

Technical information

The tender request document shall include basic information about the
pipeline design, condition and the operational conditions to which the
inspection pigs will be subjected.
The reporting level and reporting format shall be defined.
A proposed plan should be included. Drawings and welding records do not
necessarily have to be included during the tendering stage, but their availabil-
ity (or unavailability) should be mentioned.
