Wärtsilä Regas System for

India LNG Terminal

Wärtsilä will develop the regasi? cation system for a new offshore LNG terminal to be built in the Bay of Bengal. The project is headed by Crown LNG, a Norwegian group specialis- ing in developing LNG infrastructure for harsh SafeSTS weather conditions, with Oslo-based engi- neering company Aker Solutions as the main ‘Green Tech’ for Ship-to-Ship Transfers contractor. Wärtsilä Gas Solutions will conduct

A new ship-to-ship cargo transfer system has been developed the front-end engineering and design (FEED) of and patented by SafeSTS for the Dynamic Positioning (DP) shuttle the regasi? cation system. The terminal will sit tankers sector. It is designed to provide increased ? exibility and ef- on the seabed approximately 19 km north-east ? ciency for the export of oil from offshore ? elds in the challenging of Kakinada on India’s east coast, approximately offshore environments. The SafeSTS Transfer Via buoy Terminal 11 km from the shoreline. The Wärtsilä system (TVB) is designed to enable export tankers to load or discharge at will serve the terminal with an annual regasi? ca- a single point mooring (SPM) type terminal, with the DP shuttle tion capacity of 7.2 million metric tonnes, and tankers discharging in DP mode while keeping at a pre-determined will include the boil-off gas (BOG) handling distance of circa 150 meters from the export tanker. and fuel gas systems.

In the event of squalls or other environmental events, system stability is provided by the export tanker hold-back tug, whilst the

DP shuttle tanker independently holds station in relation to the export tanker. The TVB Terminal has no subsea structure apart from anchors and chains, and with the dual-carcass ? oating hoses contain- ing the oil always visible on the surface, regular maintenance and inspection is easily conducted without the use of specialist underwa- ter personnel and equipment.

The TVB Terminal can be located close to the production ? elds to provide both exceptional operational availability and increased com- mercial and environmental capability.

Odf ell Oceanwind WindGrid Floating Power

DNV completed a concept veri? cation review of Odfjell

Oceanwind’s WindGrid system for Mobile Offshore Wind Units (MOWUs). DNV’s review con? rms the technical feasibility of the

WindGrid system, and that expected reductions in CO2-emis- sions for North Sea applications are in the range of 60-70%, compared to generation of electricity from conventional gas tur- bines. Odfjell’s WindGrid is a solution for providing an uninter- rupted power supply from Mobile Offshore Wind Units (MOWUs) to micro-grids. It combines energy storage, grid converters and ? oating wind turbines in order to enable gas turbine generators to be shut down during peak wind power production.
