Abstract: In this paper, a Multidisciplinary Design Optimization (MDO) procedure is applied to a HOV design. Multidisciplinary decomposition and analyses have been developed for this complex system that includes hydrodynamics, structure, propulsion, weight & volume. The Multi-Objective Collaborative Optimization (MOCO) method is selected to conduct the preliminary conceptual design of the HOV. This approach was able to identify Pareto front designs. The results also demonstrate that MDO approaches are more suitable for design of the HOV and more flexible and advanced compared with the traditional design approach.

Abstract: The Norwegian Government has funded a feasibility study for a new ice going research vessel to replace the only Norwegian ice going research vessel “Lance”, owned by the Norwegian Polar institute and the research vessel “Jan Mayen” which is owned by a private company and used by the University of Tromsø and the Institute of Marine Research. The plan is to develop a vessel concept, budget for building and running the vessel, and all necessary support documents for an external audit of the complete feasibility study in the fall of 2008 in order for the Government to make an investment decision late 2008 or early 2009. A contract for the building of the vessel can be in place in mid-2009 at the earliest and the vessel could then be in operation in 2012. The vessel is so far planned to be a truly multifunctional research vessel. It is specially designed for operations in ice covered waters in both the Arctic and the Antarctic. The preliminary concept is based on a 92 m length and 19 m wide hull with accommodation for 50 persons and 2 small helicopters. The vessel will be host of scientific equipment for oceanographic, geological, metrological and biological observations. Sampling in the air, on the surface, in the water column, on the sea floor and under the sea floor using hydro acoustics, trawl nets, plankton nets, towed bodies, ROV, AUV, seismic, coring equipment, grabs, sledges and much more, is planned. The vessel will be used by a number of different institutions and will be a truly national asset. Several Norwegian institutions have interests in the utility of the vessel, with Norwegian Polar Institute, Institute of Marine Research, University of Tromsø and University of Bergen as primary users. This paper gives an overview of the present status of the project with focus on the planned instrumentation and scientific equipment.
Abstract: Future breakthroughs in scientific deep-sea drilling critically depend on our ability to perform field expeditions with state-of-the-art technologies and modern infrastructures. This will require major investments, both in terms of generating new, as well as maintaining and renovating existing infrastructure. Diverse models for science operations are presently projected, also within the context of scientific needs after the current phase of the IODP will come to an end. In spite of its critical role in global climate and tectonic evolution, the Arctic Ocean is one of most unexplored ocean basins of the world, its geologic and paleo-environmental history remaining largely unknown. Restricted by circulating sea ice, scientific drilling has been slow to arrive in the Arctic Ocean. After ODP Leg 151 had drilled the Yermak Plateau, it was not until 2004 that the ACEX expedition retrieved several hundred meters of sediments on top of Lomonosov Ridge, thereby proving that deep-sea drilling in permanently sea ice-covered ocean basis is principally feasible. However, it has mostly not been possible to sufficiently sample and date the sedimentary record preserved in the basin beyond the length of a single core. This dominating lack of data remains and represents one of the largest gaps of information in modern Earth Science. We here report on the planning of a new European research icebreaker and deep-sea drilling vessel, the AURORA BOREALIS, designed with an all-season capability of endurance in permanently ice-covered waters. The ship shall facilitate research in ice and open water conditions in the fields of geology, geophysics, oceanography, biology, glaciology, bathymetry, meteorology, and atmosphere physics. The icebreaker will be able to carry out deep-sea drilling in ice-covered deep-sea basins during the more favorable summer seasons in order to fulfill the needs of the IODP or its eventual successor as a Mission-Specific Platform. AURORA BOREALIS will be the most advanced polar research vessel in the world with a multi-functional role of drilling in deep ocean basins and supporting climate and environmental research and decision support for stakeholder governments within the next 35-40 years. The vessel will be a powerful research icebreaker with more than 50,000 tons displacement and an estimated length of 200 m, with about 55 Megawatt propulsion power. AURORA BOREALIS is projected as a major strategic European science infrastructure for the next generations of polar researchers in the upcoming decades. It will feature the highest attainable icebreaker classification, considerably surpassing in performance all currently operating icebreakers. Yet machinery onboard AURORA BOREALIS shall be highly energy-efficient, environmentally friendly, fully redundant, and thus allow reliable and safe operations in the most remote and hostile oceanic polar regions. New technological features to be implemented include a novel hull design and specialized dynamic positioning systems for operations under closed sea-ice cover conditions with up to 2.5 m ice thickness, combined with advanced satellite navigation and ice-forecasting support. The vessel is planned to operate routinely without ice management support by additional icebreakers, thus reducing operational costs for scientific drilling in polar regions considerably. Two moon-pools (7x7 m each) will allow routine deployment of Remotely Operated Vehicles (ROV) and Autonomous Underwater Vehicles (AUV) in ice conditions. A dedicated deep-sea drilling rig with full weather protection will enable sampling of the ocean floor in water depths down to 5000 m with 1000 m penetration under polar conditions. Following a European-wide public invitation to tender, an internationally operating naval architect and marine engineering company was contracted by the Alfred Wegner Institute for Polar and Marine Research, Bremerhaven with funds from the German Federal Ministry for Education and Research and tasked with the general arrangement planning, preparation of the initial design concept, and provision of a full tender documentation for the vessel. The general contractor’s main challenge is to provide a novel, yet technically sound and convincing ship design concept that optimally combines the wide range of tasks that AURORA BOREALIS is envisioned for by the international scientific community. The modular arrangement of science space with hangars, the possibility to flexibly equip the ship with laboratory or supply containers and with helicopters, addresses the needs of diverse disciplines in marine research. This icebreaker will allow to stage long international, interdisciplinary drilling expeditions in the central Arctic. In a long-term perspective, AURORA BOREALIS will also be used to address Antarctic research targets, both in its mode as a regular research and a scientific drilling vessel.

Abstract: R/V L'Atalante was built by Ateliers et Chantiers du Havre (ACH) and commissioned in October 1990 as a multi-purpose research vessel. L'Atalante is dedicated for research in marine geosciences, physical oceanography and marine biology. The vessel is able to operate a manned submarine system as Nautile, towed system as SAR or Rov Victor 6000, and heavy systems as Penfeld. L’Atalante is 84 meters long, 15 meters wide for a load displacement of 3550 tons. The vessel is designed to perform oceanographic missions involving deep sea submarine operations as bathymetry up to 12,000m, remote controlled submarine operations, submarine operations, heavy seismic operations, deployment of heavy systems, coring operations up to 20m, sampling operations using hydrology/CTD profiler, dredging and trawling operations. This modernization should not modify the current missions of the vessel, at most, it will adapt them to the new context of the French research fleet. The main objectives of the modernization are to replace all obsolete scientific equipment by up-to-date scientific equipment, to assure the remedial and curative maintenance at mid-life of the vessel and to provide a reliable and efficient platform appropriate to the coming 15 years of marine science. News shallow water and deep sea multibeam echo-sounders will be installed. This equipment will be integrated in a gondola instead of present fairings. All scientific spaces as laboratories and scientific centre will be re-accommodate in way to be adapted to the new scientific equipment. Presentation: < Session3-Dupont.pdf >

Abstract: This paper describes the new Ifremer road transportable survey launch: Haliotis. RV Haliotis is a 33 feet long motor boat, which has been specially designed for use in very shallow water (typically 1 to 15 meters) for near-shore habitat mapping and marine geological applications. She is associated with a semi-trailer truck fitted with a foldable crane. The truck is able to transport Haliotis anywhere on the coastal areas. Haliotis is equipped permanently with: - an interferometric sidescan sonar, - a sub bottom profiler, - a single beam echosounder associated with a bottom classification software, - inertial motion sensor and real time kinematic GPS. A light underwater video system can be towed. The crew includes 2 operators (1 helmsman – 1 sonar technician). One or exceptionally 2 scientists can also go on board. The system (Survey launch + truck and crane) has been tested and accepted during the first six-months 2008. Haliotis is now integrated into Ifremer fleet and is available for the French scientific community and chartering. Presentation: < Session3-Bisquay.pdf > |
