2013: Al Shaheen: Well-Test to Well-Stimulation

Our Conversion Operation for Al Mansoori

Well-Test• Process of testing

planned data to maximise knowledge of oil and gas wells.

• Vessels for well-testing incorporate a processing plant; capturing oil and gas flared during testing operations

Originally designed by Henderson International in 2003 for Well-Testing; commissioned by Al Mansoori in 2004.

What Was Done; Summary

• Ship was cut in the middle at 11.4.• 2x acid tanks added at midship• Alteration of air ventilation

• Re-design of piping

• Well-stimulation cabin added on upper forecastle deck

• Well-stimulation equipment installed, secured on deck• Exhaust chimney and air intake installed on deck.WHY? Vessel, initially was 60M; not meeting longitudinal length criteria.

Heavy weight of the midship, also warranted tank loading modifications; meeting strength criteria.

Ventilation, by IBC regulations was also modified for acid tanks
