Confidence generates the investment necessary to assist the technological advances that are required in our challenging industry, and a buoyant industry attracts the manpower needed to utilise it.

Naturally they focused on returning A number of IMCA members have recently reported an increase in ionospheric effects on global navigation satellite systems (GNSS), leading to an increase in DP incidents. This increase has been recently observed on monitoring systems and a number of vessels operating offshore Brazil and West Africa. Increased ionospheric activity is correlated with the following factors: sunspot activity – increased ionospheric activity linked with the 11-year solar cycle (the present cycle is expected to peak in 2013). This has been on the increase since October 2011; solar and magnetic storms – cause an increase in the ionospheric activity; their region’s activity to previous levels as well geographic location – highest activity along the geomagnetic equator and in auroral (polar) regions; seasonal variations – increased activity at the vernal and autumnal equinoxes; diurnal (daily) variations – maximum effects normally experienced one hour after local sunset until midnight. There are two different effects that are experienced: 1) Increased ionospheric activity can introduce large errors/biases (up to 15 metres) into single frequency DGNSS (both GPS and GLONASS) because of the failure in the differential process to cancel the effects of the ionospheric delay as future expansion. They also shared in the between the reference station and the user. These effects are easily mitigated by the use of dual frequency systems which don't model but measure the ionosphere error. 2) The second effect is scintillation which is caused by small scale irregularities in the ionosphere caused by the solar activity. Scintillation occurs mainly in the evening along the geomagnetic equator. It has the effect of causing fluctuations in the amplitude and phase of the carrier phase signal, introducing noise or causing loss of lock to the satellite. This results in a reduced number of usable GNSS satellites and occasionally a reduction in the L-band communications link strength, causing intermittent reception of the augmentation data. Scintillation effects are normally seen in a period of six hours after sundown but are not predictable. world-wide industry concern in communicating Although there is no way to eliminate the effects of scintillation, the following steps may help mitigate the impact of scintillation: use of GLONASS satellites to increase the number of observations available to the position solution (will help in the majority of situations but not all); use of dual beam L-band (two independent downlink satellites) for DGNSS corrections to ensure that corrections can still be received if lock to one satellite is lost. Although these steps may mitigate the effects of scintillation, in some extreme circumstances all GNSS and L-band signals challenges and rewards to the next generation may be lost, resulting in total loss of GNSS positioning. The following steps are recommended: the impact of increased ionospheric activity and the potential to lose both stable satellite and L-band communications is taken into consideration during risk assessments when planning critical offshore activities; selection and use of additional non-GNSS DP positioning reference systems to mitigate the potential for loss or instability of GNSS position during risk periods; increased vigilance of DP operators for scintillation effects, especially after sunset. Members are also referred to the following IMCA documents on satellite positioning: of workforce in readiness for the safe delivery IMCA S 012 – Guidelines on installation and maintenance of DGNSS-based positioning systems; IMCA S 015 – Guidelines for GNSS positioning in the oil & gas industry; IMCA S 018 – Guidance on the selection of satellite positioning systems for offshore applications. of oil and gas from more remote and challenging Document reference(s): For more details, please contact: Issue date: Marine Division IMCA M 21/11 [email protected] November 2011 Offshore Survey Division IMCA S 05/11 10 MARINE SURVEY12 locations. A welcome common message from the speakers was that the conference gathered a significant representation of the marine contracting world, and that IMCA should be part of discussions about matters affecting this sector. This is an important responsibility for 13 IMCA, and its members need to contribute ROV SPOTLIGHT14 both individually and collectively to the debates. They need to seek out opportunities D and points of contact in relevant bodies to do this, and actively respond to calls for comment I issued by the secretariat. Only in this way will IMCA’s voice truly reflect members’ wishes RE and be heard and respected by relevant bodies. Having earned this recognition we must use it DIRECTORY15 EVENTS20 wisely and be careful not to lose it. C 2 TOR Y big talk in the big easy the IMCa annual seminar enjoys some southern hospitality This issue’s cover shows the fleur de lys – a symbol of New Orleans since its birth – and beads associated with the Mardi Gras that the city is so famous for. New Orleans, USA hosted the nineteenth IMCA annual seminar from 9-10 November, with its theme on The future of marine and subsea operations attracting over 340 delegates. Endorsed by the Offshore Support Journal, IADC, OGP, MTS dynamic positioning committee, API, ADC International, OCIMF and OOC, there was a range of presentations, workshops, social events and an exhibition with stands from 19 different companies. Hugh Williams welcomed delegates before Alan Allred of EMAS – Chairman, IMCA Central & North America Section – introduced the keynote speakers: IMCA President Andy Woolgar of Subsea 7, Mike Casey of Chevron E&P, Randall Luthi of the National Oceans Industries Association, Erik Milito of the American Petroleum Institute and Secretary Scott Angelle from the Louisiana Department of Natural Resources (DNR), who all spoke on this year’s theme and were enthusiastically greeted by the delegates. The morning plenary session included presentations on deep ocean seafloor extraction, a new reeling method for a state of the art multi-purpose vessel and better workability through DSV integration. The seminar then split into three parallel sessions on Marine, Diving and ROV & Survey. Presentations were given at all three followed by technical workshops covering blackout recovery for DP vessels, ROV installation, working in Arctic conditions, lifeboats and security issues. The day was pleasantly concluded with dinner on board the Steamboat Natchez while cruising down the Mississippi river. Delegates sampled the delicious local cuisine and viewed the steamboat’s engine room. Day two started with a keynote note address by Lars Herbst from the Bureau of Safety and Environmental Enforcement (BSEE) with Bruce Gresham, Heerema Marine Contractors – Vice-Chairman, IMCA Central & North America Section – introducing a plenary session. This included three presentations covering the use of video games in the offshore industry, marine accidents and their investigation, and the impact of fatigue on ships’ watchkeeping officers. The technical session again split into three sections and included presentations in Marine, Diving and ROV & Survey. A final plenary session followed with two presentations, one covering process safety and the other the application of STCW 2010 and the Maritime Labour Convention 2006 to the offshore sector. The final workshop sessions covered the topics of the pitfalls of position references, the MLC and its impact on marine contractors, the diving industry for the 21st century, process safety and this year’s delegates’ choice on vessel assurance. The workshop sessions and seminar were summarised by Hugh Williams who thanked all speakers, chairmen, attendees and staff involved in the seminar. The seminar was concluded with a lively drinks and buffet reception at Audubon Nature Institute, Aquarium of the Americas. A CD of all presentations and summaries is being prepared and will be sent to all members and delegates in due course.
