y a large buoyant structure when disconnected. The<br />

Company has therefore developed a specific product<br />

for this application, the MoorSpar, which now<br />

enables SCRs to be deployed with a disconnectable<br />

FPSO. The MoorSpar expands the opportunities for<br />

disconnectable FPSOs into ultra-deepwater or difficult<br />

reservoirs where SCRs are required.<br />

The Company continues to develop and increase the<br />

capacity of its proprietary swivel systems. Current<br />

work includes expanding the pressure and temperature<br />

range of our existing fluid swivels, and developing<br />

a new large-capacity High Voltage (HV) electrical<br />

swivel. For the HV swivel, qualification tests have been<br />

performed at 36 kV and up to 1500 Amps, enabling<br />

the Company to meet the increasing demands of the<br />

industry for HV power transfer systems.<br />

Gravity Actuated Pipe<br />

The Gravity Actuated Pipe (GAP) was developed<br />

several years ago and is now successfully in operation<br />

in the Kikeh field in Malaysia where it acts as a<br />

mid-water connection between the Company-owned<br />

FPSO Kikeh with a satellite floating dry tree wellhead<br />

unit. Further development of the GAP product continues<br />

with specific focus on increasing the operating<br />

envelope in terms of higher payload and longer distance<br />

between the two floating bodies.<br />

Steel Catenary Risers<br />

In ultra-deep water, riser systems comprise an increasingly<br />

significant part of the overall field development<br />

costs and have become more technically challenging.<br />

Traditional unbonded flexible riser solutions become<br />

increasingly heavy and expensive and are at the limit of<br />

their application range. Steel Catenary Risers (SCRs)<br />

offer advantages over unbonded flexible risers by being<br />

more cost effective while having a wider range of application<br />

in these ultra-deepwater conditions.<br />

A breakthrough in the use of SCRs was achieved in<br />

2009 with the first ever deployment on a turret moored<br />

FPSO. The Company successfully connected and commissioned<br />

a Lazy-Wave steel riser system (supplied<br />

by others) to the FPSO Espirito Santo, in Brazil. This<br />

innovation was recognised at the 2009 Deep <strong>Offshore</strong><br />

Technology International conference with the “Best<br />

<strong>Report</strong> of the Board of Management<br />

Technical Innovation” award. Operating in approximately<br />

1,800 metres water depth, this system is classified as an<br />

ultra-deepwater project. Further study work to expand<br />

the operational range of SCRs for use in harsher environments<br />

and at reduced water depths down to around<br />

1,000 metres was completed. This allows the Company to<br />

offer SCRs with FPSOs, TLPs and semi-submersibles for<br />

service conditions found in almost all deep to ultra-deep<br />

development areas.<br />

The traditional design of SCRs utilises welded pipe sections<br />

which require expensive S or J-lay installation<br />

vessels. The normal weld procedures used with these<br />

installation vessels precludes the use of some very<br />

high-grade steels, which would be very advantageous<br />

in greater depths with high-pressure and/or high-temperature<br />

wells. The Company has therefore developed a<br />

competitive alternative method for SCR fabrication and<br />

installation using fatigue-resistant threaded mechanical<br />

connectors. This allows much faster offshore jointing<br />

of the SCR sections and avoids the need for traditional<br />

field-welded joints. This method therefore allows and<br />

facilitates use of very high-grade steel pipe required for<br />

some ultra-deepwater wells, and also significantly reduces<br />

installation time offshore. The qualification programme<br />

for the Company’s connector was completed in 2009 in<br />

accordance with the ISO/DIS 21329 standard, making this<br />

connector now commercially available.<br />

LNG Production, Transfer and<br />

Storage Systems<br />

Acknowledging the growing importance of gas as a world<br />

energy source, the Company has maintained its focus on<br />

developing technologies and infrastructure associated<br />

with enabling offshore floating LNG-based projects. Such<br />

projects are now starting to be developed by several leading<br />

oil and gas operators and the required technology is<br />

rapidly maturing in a number of areas. The Company is<br />

currently working in the following areas for LNG projects:<br />

• the FLNG for offshore production of LNG;<br />

• cryogenic floating hose for LNG transfer;<br />

• offshore floating LNG storage, regasification and export<br />

to pipeline.<br />

The Company, together with its partners, remains at the<br />

forefront of these developments. <strong>SBM</strong> <strong>Offshore</strong> believes<br />
