Offshore Oil & Gas Products At the 2007 Offshore Technology Conference (OTC), 13 innovative technologies were recognized with Spotlight on New Technology awards. Following are details on this year's winners. product focus MOSES Self Stable Integrated Platform TLP Single Buoy Moorings Future LNG transfer with weathervaning Offshore LNG Terminals is now feasible. SBM has completed an in-house, three-year development program for the world's first LNG Toroidal Swivel. This swivel with its central opening is a key requirement for any marine transportation system where LNG has been transferred for import or export through a weathervaning system whether it is turret or single point mooring. The design can be configured to allow the passage of multiple LNG streams up to 20 inches and a 16 inch vapor return. Thanks to composite material bearings and the use of thermal rods inside the toroid, the swivel sealing function is shielded from thermal deformations when cooled to its -165 degree Celsius operating temperature and 10.5 bar pressure. The MOSES Self Stable Integrated Platform (SSIP) is a Tension Leg Platform (TLP) that has inherent stability that allows quayside integration and commissioning of the topsides to the hull structure, wet towing of the integrated platform to the installation site, and eliminates the need for expensive temporary buoyancy or craned assisted installation assistance. The hull configuration is comprised of a central base structure, four Tendon Support Structures (TSS) and four vertical columns. The base and TSS structures are located deep below the surface and provide a significant portion of the platform's buoyancy. Each TSS is a rectangular pontoon structure. The columns are located further outboard, smaller than conventional TLP columns, and are rectangular in shape. A total of eight tendons are supported at the end of the TSS (two at each end) via top connectors on a porch arrangement. The tendons are connected at the sea bottom on piles via bottom connectors. The MOSES SSIP TLP can support a variety of drilling or workover rigs and a large number of Top Tension Risers (TTR's) and flowline risers. The MOSES SSIP TLP can be used with wet and/or dry trees in harsh and mild environments. www.seadiscovery.com as small as possible - a micro-influx or micro-outflux. The System is designed to incorporate existing drilling and pressure control equipment with minimal upgrades and equipment additions. In its most basic form, the Secure Drilling System allows the Driller to "see" on screen real-time changes in, and deviations from, expected behavior in flow and pressures. The Driller can use the technology to interpret these changes and effect control on the situation through computer-controlled equipment that makes adjustments in the flow regime in response to the changes in downhole or surface conditions. Deck Raising System The systems used to raise the two eight leg platforms utilized 32 synchronously controlled, 260ton hydraulic cylinders to lift the platforms 14 ft. each. The cylinders pin into lower padeyes welded to the existing legs and upper padeyes integral to the split extension sleeve. The 40.5-in. diameter, 1.5-in. wall extension sleeves capture the legs during the final leg cuts and with the rub rails, limit lateral movement during raising to 0.25-in. The legs are cut between two bushings installed near the top of the legs. Prior to the lift, the top of the extension sleeve is welded to the upper bushing, and after rising, the bottom of the extenMarine Technology Reporter 55 Secure Drilling System The Secure Drilling System is a closed-loop system which analyzes available drilling data to detect kicks or losses, and automatically manages backpressure at the surface to control influxes or losses. The System allows the volumes to be kept
