Recognized for its technical excellence, this project was featured at the 24th International Offshore (Ocean) and Polar Engineering Conference (ISOPE) in 2014.
Project Overview
Project Overview
A 360,000 BPSD condensate refinery in Bandar Abbas has been carried out by Persian Gulf Star
Oil Company, where a seawater intake system was designed to supply 200,000 cubic meters
clean water from 1500m offshore by 4 x 2.7m diameter steel marine pipelines for cooling
purposes.

Hence, seawater would be collected at the basin through four steel pipes of 2.7m
inner diameter and 22mm thickness which were connected together as a 600m string.
The length of the pipeline route is approximately 1.4 km, including two strings of 600
meters and shore approach line of 130 m.

Although, this was a huge and a high-risk project due to the
pipeline’s material and its ultra-large dimensions, it was carried out with the most safety
and reliability. All activities related to floating and flooding (subsea installation),
including offshore tie-ins between two individual strings has successfully completed by
Delta offshore Technology in just a few hours that was much less than as the client expected
