Project Activities

SubseaCo has played an integral part in establishing and driving energy projects and related business initiatives in the UK, Norway, Texas, the Philippines, Singapore, Malaysia, New Zealand and Australia.

SubseaCo has, as subcontractors to oil companies and engineering groups, project managed and led engineering teams on field developments such as:

  • Agip Toni (UKCS)
  • Shell Malampaya (Philippines)
  • STOS Maui AD Ihi (New Zealand)
  • Anzon Basker Manta Gummy (Bass Strait)
  • Santos Casino (Bass Strait)
  • AED Puffin Field (Timor Sea)
  • BC Petroleum Balai Cluster (Malaysia)

Our people have also led various field development studies for:

  • Aker / Statoil - Haltenbakken, Yme
  • Santos - Mutineer Exeter

and have carried out pre-FEED work for Worley Parsons on:

  • BHPB - Stybarrow and nearby fields
  • Chevron Texaco - Gorgon
  • Other projects in Western Australia

On behalf of our clients we have run programmes to rationalise their subsea businesses, set up joint ventures for local manufacturing, and implemented initiatives to increase business unit profitability and reduce operational costs.

SubseaCo's preferred working model is to provide its own leading specialists as a nucleus for the establishment of wider project teams comprising client and contractor personnel.

We have proven systems in place that can be adapted to suit each project and business initiative. Importantly, SubseaCo always keeps firmly focused on HSEQ responsibilities.

A sample of recent projects are included below:

2011 – 2013 Marginal Fields Offshore Malaysia – Balai Cluster (Water Depth ~ 60M)

Project management, engineering and project support activities for Balai Cluster marginal small fields’ development project undertaken by BC Petroleum Sdn Bhd a Joint Venture between ROC Oil Limited, Dialog Group Sdn Bhd and Petronas Carigali Sdn Bhd. This phase undertook geology and geophysics, drilling and testing of appraisal wells including the construction of floating and wellhead platform production facilities and equipment.

SubseaCo's primary scope was the project management, engineering, assembly, testing and commissioning of a high pressure transfer system including FPSO mounted riser deployment and hawser deployment reelers. The system included a hose landing and testing platform, over boarding chute, HP transfer hose, quick connect/ disconnect couplers and wellhead platform mounted winching and skid packages.

2006 – 2011 Offshore Northern Territory - Puffin Field Development Phase 1 (Water Depth ~ 90M)

Project management, engineering and project support activities for the Puffin Field Development for AED Oil Limited and later their JV partner Sinopec. Initially SubseaCo's principals consulted through Oceaneering (formerly AGR Group) on subsurface, drilling, installation and testing two (2) initial development wells including the procurement of related facilities and equipment in particular the seabed equipment, flowlines, risers, tie-in systems and moorings. After first oil, the principals of SubseaCo ran the offshore operations for AED until the operatorship was taken over by Sinopec whereupon AED's involvement was via JV arrangements.

2005 – 2006 Offshore Victoria - Basker Manta Field Development - EPT and FFD Phases (Water Depth ~ 100 – 200M)

SubseaCo was subcontracted to the BMG Joint Venture Operator Upstream Petroleum (UP) to manage the Basker-Manta development project. SubseaCo sourced additional personnel from its prior projects to augment the team.

SubseaCo project managed all BMG requirements including the drilling and FPSO conversion operations. It led the procurement, delivery, installation, hookup and commissioning of the risers, flowlines, umbilicals and mooring systems for both the Early Production Test (EPT) and the Full Field Development (FFD) Phases. Installation for the EPT phase was carried out by Technip and the FFD installation works were carried out by Clough, all as directed by SubseaCo's Project Manager.

The FFD FPSO conversion upgrade required additional process modules and a larger compression system. Additional wells - Basker 3, 4 and 5 and Manta 2a -were drilled for FFD and a subsea manifold was installed. The Basker wells were controlled using manifold mounted subsea control modules. Manta 2A produced through its own dedicated riser and was controlled by direct hydraulics.

2002 – 2005 Offshore Victoria - Casino Field Development Project - Santos Limited (Water Depth ~ 70M)

Casino was a two well gas development 34 km from shore in Bass Strait near Port Campbell in Victoria. SubseaCo led the WorleyParsons project management and engineering teams in conducting FEED, project risk assessments, preliminary and detailed design, FID gate approvals, preparation of specifications and procurement packages, supervision of manufacturing, assembly and testing, quality assurance, surveillance and system integration testing.

The project comprised:

  • 2 subsea trees and diverless connection systems
  • 10" CRA pipeline x 34 km
  • 3 x inline tees to the pipeline
  • Subsea control system - EH Mux
  • MEG delivery system
  • Horizontally directionally drilled (HDD) shore crossing
  • Onshore remote land fall station pigging and control station
  • Onshore pipeline
  • Process tie in modules to existing TXU WUGS gas processing plant.

1998 – 2001 Offshore Philippines - Malampaya Gas to Power Development (Water Depth ~ 850M)

The Malampaya gas field is located 80 kilometres northwest of Palawan island Republic of Philippines. Shell Exploration (Philippines) drilled five wells to determine and harness the resource potential of 2.7 trillion cubic feet of natural gas reserves and 85 million barrels of condensate.

The development of Malampaya posed a myriad of daunting logistical, social, environmental, and financial challenges. It required the active participation and involvement of government agencies, communities, and both Filipino and multinational companies. The DOE played a key role in making Malampaya a reality.

Cooper Cameron Corporation Inc contracted SubseaCo’s small team to assist in developing subsea field layout concepts, design and manufacture of the subsea tree’s, a manifold, pipeline End modules and tie-in systems. In addition a state of the art electro hydraulic multiplex controls system were designed and built. An international project team (located across the UK, Singapore, USA and the Philippines) was led by SubseaCo's project manager carrying out FEED, detailed design, manufacture, assembly, testing and installation for and on behalf of Cooper Cameron.
