Challenge

World-class thermal performance and ability to bury the PIP in congested corridor with national highway, national rail track and populated areas was critical for BPCL. Fast track execution was required to meet Clients agressive schedule.

PIP installation was conducted during difficult and unpredictable Covid-19 pandemic, with related lockdown / stoppage of the works prior completion.

Key to success

Anticipation and Flexibility was required to adjust to schedule’s constraints and modification. Engineering anticipated Procurement requirements and advance long-lead delivery schedule. All detailed guidelines and specifications were accelerated to facilitate operations and contractor’s training for pipe-in-pipe assembly activities. The PIP was designed to ease assembly with modular construction activities.

In the face of pandemic and travel restrictions, ITP immediately implemented a remote quality control process to enable the client to continue his installation operations with local quality control on site.

Gujarat Buried Cryopipe

The world’s first fully buried Cryogenic pipeline for the loading of Ethane and LNG from an existing jetty to a new storage tank. The two parallel 24” lines are buried along a congested corridor with dozens of bends and several road crossings. For the design temperature of -168°C , a high-performance PIP was required to limit boil-off gas and enable a fully constrained buried application, without expansion loops. ITP was contracted in 2015 for the engineering, procurement, pre-fabrication and installation supervision. The system is operating since early 2017.
