Engineering and project management services for the offshore and onshore industry

SubseaCo is experienced in oil and gas developments, floating production storage and offloading vessels (FPSOs), liquefied natural gas (LNG) carriers and re-gasification systems and offers engineering and management services for onshore and offshore production facilities, subsea systems and SURF projects.

The company aims to improve construction efficiencies and lower operational costs.

SubseaCo has carried out a wide range of subsea and offshore operations and development programmes, including engineering and project management, FPSO conversions, pipeline connections, flowlines, umbilicals, high-pressure fluid transfer systems, subsea equipment specifications and procurement, logistics and installation support.

Our qualified engineers, project managers and marine specialists are experienced in delivering significant projects, covering:

  • HSEQ and compliance
  • Subsea systems
  • Topsides
  • Installation and commissioning management
  • FPSO sourcing and conversions
  • Operations management
  • Engineering, procurement, and construction management (EPCM) services

Marine project delivery, procurement and feasibility studies

SubseaCo carries out pre-feasibility, concept and front-end engineering design (FEED) studies. We prepare field development plans, develop FPSO, subsea equipment and platform specifications and produce procurement packages. Further we have arranged the implementation of drilling programmes.  

For offshore works, our scope and activities have included:

  • Procurement, design reviews, delivery of wellheads, downhole completions, subsea trees, manifolds, connection systems, flowlines, umbilicals and subsea controls
  • Onshore and offshore pipelines, horizontal directional drilling (HHD) shore crossings and gas processing plant integration
  • FPSO conversion works, mooring systems and offshore installation campaigns to tie the wells back to the production systems
  • High-pressure transfer systems that can be freely connected and disconnected using dry break couplers and hose recovery systems
  • Associated quality management and surveillance programmes, including factory acceptance test (FAT) and integration testing programmes

SubseaCo also performs energy infrastructure reviews, technical bid support services, and prefeasibility and concept selection studies, field development plans, safety case applications and environmental impact assessments for onshore and near offshore projects.

Our personnel have provided technical recovery and turnaround service support to major clients in their initiatives to provide more cost-effective and efficient energy solutions. We have also supported significant government grant applications.

Seabed equipment, flowlines, risers, installation support and commissioning services for offshore projects

Between 2005 and 2007, SubseaCo undertook subsea and FPSO conversion management and operations support of the Basker Manta field development for Upstream Petroleum Pty. The company undertook management of design, procurement, delivery, installation, hook-up and commissioning.

During 2007 to 2011, the company supplied a wide range of engineering services for the Puffin Project in the Timor Sea on behalf of AGR. We managed the delivery and integration of seabed equipment with flowlines, risers, umbilicals, jumpers, tie-in systems and moorings.

We arranged the transporting of risers, flowlines, umbilicals, the STP buoy, the connection systems and mooring systems into consolidated shipments to Singapore, where transpooling and preparation for the offshore installation campaign was affected and DSV loading was carried out.

From 2011 to 2013, SubseaCo arranged and carried out the engineering, assembly, testing and commissioning of a high-pressure transfer system for the BC Petroleum Sdn Bhd joint venture (ROC Oil, Dialog Group Sdn Bhd and Petronas Carigali Sdn Bhd.) at a marginal field in offshore Malaysia.

For this development, we specified and managed the FPSO-mounted riser and (separately) hawser deployment reelers, the hose landing and testing platforms and the transfer system venting & pressure management systems. Other equipment specified and procured included over boarding chutes, high-pressure transfer hoses, quick connect / disconnect couplers, and wellhead platform-mounted winching and skid packages.

Lean implementation of efficient LNG and green energy developments

SubseaCo focuses on lean construction and implementation, supporting clients to replace poor and inefficient systems and processes with more effective and streamlined alternatives.

We work to find and implement energy-efficient technologies and practices, as well as optimising cleaner fuel solutions such as natural gas over oil. Our personnel lead studies and implementation programmes for the use of LNG shipping and distribution for power projects within archipelago nations.

SubseaCo has experts in mini LNG and re-gasification technology, covering all aspects of LNG shipping, offtake systems, distribution networks, carriers, articulated barges and re-gasification facilities. The company collaborates with energy producers to define and implement next phase development of their national power requirements, including clean technologies such as solar, wind power and bio-fuels.
