In order to supply seawater for cooling onshore facilities of South Pars Phases 19, located at south of Iran east of Kangan Port, a seawater intake systems is being developed by Petropars Iran.

In this project, seawater will be collected at the basin through two 2m/length1200m high density polyethylene (HDPE) pipes.
Warmed discharge water will be returned to the sea using an approximately 200m length outfall HDPE pipe.

Delta Offshore Technology (Delta) accomplished the pre-engineering surveys such as hydrographic and sub-bottom surveys and geotechnical studies, basic and detail design, installation engineering, procurement, and construction and installation operations of the SPD19 seawater intake system.

Similar to marine pipeline of the SP12 seawater intake system, herein ballasting weight of the pipelines will be provided by injecting grout inside the core-tube pipes inside the HDPE pipes.

HDPE pipelines are fabricated onshore, towed to the location and installed using the float and sink method.
They have been laid in a trench and backfilled to be protected from exposure to any danger that will cause damage to the pipeline for example ship's anchor drag on the seabed.

SADRA is developing the P.G Star Refinery seawater intake system. The project consists of installation of four 2.7m/length1300m steel pipelines.

Delta Offshore Technology is cooperating with SADRA in executing the installation, engineering and management of the describe pipelines, which includes the following activities:

• Quality control procedure of the pipe strings

• Floating pipe strings and relocating from fabrication yard to the installation location

• Connecting strings of pipes together

• Sinking the pipeline and installation at the designated location only in three days

In order to supply seawater for cooling onshore facilities of South Pars Phases 12, located at south of Iran east of Kangan Port, a seawater intake systems is being developed by joint venture of Daelim, Sazeh and Kayson (DSK).

In this seawater intake system, seawater is collected at the basin through two 2m/length1200m high density polyethylene (HDPE) pipes.

Warmed discharge water returned to the sea using an approximately 200m length outfall HDPE pipe.

Delta Offshore Technology (Delta) as one of the leading offshore companies in Iran accomplished the installation engineering, procurement, construction and installation operations of the offshore part of the SPD12 seawater intake system Seawater intake systems filter fishes and other particles in the seawater and collect only clear water from the sea floor, without installing structures which might affect the sea environment.

In the seawater intake system the difference in water level causes seawater to flow into the intake pipe and collect clear seawater in the Sea water intake Basin at onshore.
