‘Full picture’ delivery integrates hydroacoustic, research, navigation and manoeuvering


K


ongsberg Maritime has signed a contract with Freire Shipyard for the supply of a


comprehensive integrated systems package to be installed aboard an advanced research vessel currently under construction at the Spanish shipbuilders Vigo yard for the Natural Environment Research Council (NERC). The new vessel is being built as a high


technology replacement for NERC’s RRS Discovery, which has been in service since the early 1960s. The new 100m vessel, also called RRS Discovery has been designed by Skipsteknisk AS in Norway and is due for completion summer 2013, at a total project cost of £75 million. Within the scientific community, the new RRS Discovery is seen as state- of-the-art in terms of design and functionality. A suite of cutting-edge hydroacoustic


instruments accounts for about 80 per cent of the Kongsberg Maritime systems destined for the new RRS Discovery. In close co-operation with NERC, high levels of integration have been developed across the entire package, which includes:


 Hydrography - Deepwater Multibeam EM122 (1ºx1º), medium water wideband Multibeam EM710 (2ºx2º), single-beam EA600 and for geophysics applications, sub-bottom profiler SBP120.


 Fishery Research - Simrad EK60 scientific multi- frequency echosounder.


 Integration - K-Sync synchronizing unit.  Navigation - K- Bridge Integrated Bridge System.


 Dynamic Positioning - K-Pos and C-Joy with DP1 (AM).


 Video - Marine CCTV system.


“Kongsberg Maritime will become more than a systems supplier for RRS Discovery as we will work closely with the shipyard and NERC during the entire project,” comments Vicente Carrasco (Subsea Dept, Simrad Spain SL), Kongsberg Maritime. “We are providing a dedicated Project Management service and the combined NERC and Kongsberg Maritime development of the systems for RRS


Discovery is an exciting prospect for the entire team.” Kongsberg Maritime has also supplied


hydrography systems to another research vessel in production at Freire Shipyard, for owner Qatar University. Kongsberg Maritime is a supplier of integrated systems to research vessels. Projects include extensive system packages for NERC’s RRS James Cook, the T-AGS 60 class survey vessels operated by the US Naval Oceanographic Office (NAVOCEANO), and in 2010 the National Science Foundation’s Alaska Region Research Vessel (ARRV), R/V Sikuliaq and the US Coast Guard’s high latitude research dedicated icebreaker, Healy. “We have provided systems to many of the most


advanced research vessels, and in conjunction with technically orientated organisations like NERC, we have developed a wealth of knowledge on research systems and integration,” continues Peter Bennett, Sales Manager Hydrography (UK and Ireland). 

East Greenland reprocessing agreement S


pectrum has signed an agreement with the Geological Survey of Denmark and Greenland


(GEUS) to reprocess more than 7800kms of 2D seismic data offshore the east coast of Greenland. This data will be processed though Pre-Stack Time Migration (PSTM) and subsequently licensed on a Multi-Client basis. The data consists of three surveys known as the


NAD project, which were acquired during the 1980’s offshore East Greenland. The data is located between 62 and 72 degrees


north and ties many of the wells drilled by Ocean Drilling Program (ODP) between 1993 and 1995. Competitive bidding for the area is scheduled in 2012 and 2013, as designated by Greenland’s Bureau of Minerals & Petroleum (BMP). The survey area includes the southern part of the East Greenland rift basins. A 2007 US Geological Survey (USGS) assessment


over this province indicated undiscovered oil and gas reserves of 31 400 MMBOE (million barrels of oil equivalent). East Greenland forms the conjugate margin to the Norwegian continental shelf, Faroe-Shetland


Islands and Rockall Basins. It is considered that analogues of successful play types found in these relatively well explored petroleum provinces can be extrapolated into the East Greenland offshore frontier area. This offshore area is considered frontier in hydrocarbon exploration terms, with only limited, regional, wide-spaced 2D seismic lines available and only a few ODP wells drilled. Outcrop data from onshore East Greenland and


previous interpretation of the existing offshore seismic data has suggested elements of a working hydrocarbon system could be present in the area covered by the Spectrum reprocessed data. Tertiary sediment thicknesses of up to 6 km


have been postulated in offshore South Eastern Greenland basins (below 72 degrees north) and possible Tertiary and Mesozoic reservoirs could be present in the form of fluvio/deltaic and submarine sandstones. Extensive offshore Lower Tertiary Basalts


observed on seismic sections in the northern portion of the study area are almost certain to overlie Mesozoic and Palaeocene sediments. Spectrum reprocessing of vintage 2D seismic


data in the India West Coast offshore region was able to effectively image below Tertiary Deccan Basalts and successfully identify and image pre- basalt Mesozoic stratigraphic sequences for the first time. It is hoped that by using the same techniques, the East Greenland pre-Tertiary basalt sedimentary section imaging can be improved and subsequently be interpreted.The reprocessing of the vintage seismic data will be carried out in Spectrum’s state of the art processing centre. A thorough parameter testing sequence will


be applied to the data to ensure the best possible quality for final products. The application of PSTM will be an integral part of the final sequence and the final product will be added to Spectrum’s rapidly expanding Multi-Client data library towards the end of the year. Spectrum provides innovative multi-client


surveys, high quality seismic data processing and offshore seismic data acquisition to the global oil and gas industry from offices in the UK, USA, Singapore and Australia. 
