Previous Projects

Motiva Port Author Refinery Crude Expansion Project

The project took five years to finish and increased the refinery capacity 325,000 b/p to increase capacity to 600,000 b/p. The facility can process a wide variety of crude oil from light to heavy crude. PHSC was the lead contractor HFE support from FEED through Detailed Design. Tasks included but were not limited to: develop the project HFE implementation plan, develop project HFE specifications, providing HFE support during 30%, 50%, and 90% 3DModel reviews, and working closely with the designers and client HFE team to integrate HFE with the client and contractor during the project.

Gorgon LNG

The Gorgon gas project is a natural gas project in Western Australia, involving the development of the Greater Gorgon gas fields, subsea gas-gathering infrastructure, and a liquefied natural gas (LNG) plant on Barrow Island. It is currently under construction and once completed, will become Australia's fourth LNG export development. PHSC provided project support through FEED including: writing the implementation plan and specifications.

Angola Block 18

The Greater Plutonio accumulation lies in 1,200m to 1,500m of water, 160km northwest of Luanda in the Block 18 concession and is the first BP-operated asset in Angola. It has total estimated reserves of about 750 million barrels, making it one of the biggest off Angola’s coast. Kellogg Brown & Root oversaw the engineering, procurement, construction and management, and Hyundai Heavy Industries fabricated the FPSO hull and topside equipment, at an estimated cost of $650m. PHSC supported the project by providing the development team with HFE training during the early stages.

Angola LNG

Angola LNG is a major LNG producer with operations in Angola. The plant will have a capacity of 5.2 million tons (6.8 Bcm) per year, 360,000 cm of full containment LNG storage, LPG and condensate storage and a loading jetty sized to accommodate ships up to 210 cm. PHSC provided HFE support by writing the HFE plan, specifications, valve criticality analysis. PHSC also participated in 30% and 50% 3D model reviews for the project.

Belanak FPSO

Development of the ConocoPhillips Belanak field offshore Indonesia will combine a range of production structures, including two drilling platforms, an FPSO, a floating storage and offloading (FSO) vessel, and a variety of subsea connections. PHSC provided HFE support performing a lessons learned review in conjunction with the FSPO.

Tangguh LNG

The LNG plant initially comprises of two production trains with an annual production capacity of a maximum 7.6 million tones. An LNG train consists of equipment that purifies and liquefies the natural gas, complete with LNG tanks and condensate tank. Supporting facilities such as offices, accommodation, clinic, warehouse, marine facilities, waste management facilities and workshop are available at site. In addition to the main facilities at Tangguh LNG site, Tangguh LNG also operates small camp, airfield and jetty at Babo. Babo is about 1.5 hour by boat from Tangguh LNG site. Tangguh LNG is a grassroots facility for producing LNG and condensate. The LNG plant site is located on the southern shores of Bintuni Bay in Bintuni Bay Regency of Papua Barat Province. PHSC performed an EERA Emergency Egress and Rescue Analysis for the facility.

Offshore living quarters

PHSC provided initial FEED activities including, review of specs and generating questions , HFE implementation plan, living quarters specifications, spec checklist, HFE review layout of layout designs, and developing Preliminary Design Checklist.

PHSC’s current LNG project

PHSC’s current LNG project will go from FEED through Construction. Activities performed during this project include by are not limited to: Human Factors implementation plan, HFE training, vendor activities, on-sit support, 3D and 2D model reviews, constructions site and mod yard walkthroughs.
