The first work scope comprised 58 core locations offshore Norfolk. Specialist Geotechnical Survey Vessel, MV Flatholm (above), was mobilized and work scope com- pleted with Coastline?s ?High Powered Vibrocore, ?C-Core-HP?, in 5m configuration, average recovery overall was 4m. The second work scope comprised of 70 core locations, spread over four licence areas, offshore of Lincolnshire and North Norfolk, the furthest area being 27 miles off the North Norfolk coast. Overall, the work was com- pleted port to port, Lowestoft, in less than 4 days with an average recovery of 4m completed by the experienced team onboard. SMD, SeeByte Deliver onPartnership Agreement SeeByte and Soil Machine Dynamics Limited (SMD)announced their latest plans as part of their on-going technology partner- ship. SeeByte and SMD plan tointegrate a smart software tool for dynamic posi-tioning and real- time monitoring of ROVs, based on integrating SeeByte?s CoPilot tech- nology into SMD?s DVECSII control platform. This will be available on SMD?s latest generation ROV sys- tems, the first of which is the Atom. SeeTrack CoPilot offers the industry?s most extensive range of operation modes such as station-keeping,cruise-control, survey-control, multi- beam imaging, sonar track and mid-water DP. SMD?s ROVs, equipped with SeeTrack CoPilot, will boast the industry?s most advanced ROV con- trol for survey purposes and unparal- leled control performance for con- struction duties. MMT Wins Survey Deal Statnett SF and National Grid International Ltd have awarded MMT (Sweden) the marine survey contract for the NSN Seabed survey, a power transmission link between Norway and UK. Statnett and National Grid are jointly developing a project to construct a High Voltage Direct Current (HVDC) electrical interconnector between Norway and Great Britain. MMT will be perform- ing the route survey for this project between Hylen, Norway and Blyth, UK. The survey will be performed April ? August 2012. The length of the cable route is approximately 711 km and the assignment includes geophysical,geotechnical, benthic, archaeological and ROV operations. For the offshore part, MMT will provide geophysical and benthic sur- veys from MV Franklin. The offshore survey vessel Stril Explorer is assigned for the ROV and geotechnical inves- tigations. MMT?s vibrocorer and CPT will be launched from Stril Explorer for seabed sampling. Bibby Offshore Charter Agreement Bibby Offshore signed a three- year bareboat charter agreement with Solstad Offshore Asia Pacific Ltd for the NOR Spring, a DP2 (Dynamic Positioning) Anchor Handling Support Vessel (AHSV). The 2008-built NOR Spring comes with a proven track record in the Middle East and Asia- Pacific. The vessel has 600 sq. m. of free deck space as well as an ROV mezzanine deck and multi- ple DP reference systems including fanbeam and taut-wire. The ship is equipped with a subsea 20m ton @15m Active Heave Compensated (AHC) knuckle-boom crane suit-able for man-riding and can be fit-ted with an existing 40 ton Safe Working Load (SWL) A-frame if required. NOR Spring has accommoda- tion for 60 personnel and a built-in hospital making it ideal forROV and diving operations which involve large project and client teams.For the first contract starting in May, Bibby Offshore will be mobi- lizing the NOR Spring in Singapore with a survey spread and two newly-purchased TMS inspec- tion class Seaeye Lynx ROVs.
