Abstract. A low-cost Unmanned Aerial Vehicle is compared with those already available and the motivation for its development is established. It is targeted at ship-based science missions and potential applications are described including a specific science case to measure white capping in the deep ocean. The current vehicle includes a range of more than 1000 km, carrying a payload of 2 kg and it can be launched and recovered from a coastal research vessel. The vehicle has flown successfully in Force 4 gusting Force 6–7 wind conditions, an important requirement for operation at sea. Data analysis is performed on images captured by the vehicle to provide a measurement of wave period and white capping fraction. The next stage of the project is to develop a suitable payload and perform a demonstration science mission.

The design of the SIVA TH (small waterplane area, twin hull) research vessel Western Flyer is described. Because the Flyer is intended to serve as mother-ship for an advanced deep-diving ROV (remote-operated vehicle) to be deployed in CaliJbrnia's Monterey Bay area, the SWATH configuration presents a safe and stable pla(form [kom which to operate in practically all weather conditions. Launch and retrieval of the ROV./?om the sheltered moonpool, or centerwell, are discussed as well as the elaborate 7'ether Alanagement System. The deck and machinery arrangements" are illustrated, and model tests to predict the SWA TH's station keeping qualities and pitch motions in various sea states are described.

The United States fleet of oceanographic ships has grown to a significant segment of the national program in marine sciences. The growth has occurred over a 25-year span that can be divided into four distinct periods. The evolution of design and construction led to the consideration of the offshore supply vessel as a possible hull form for adaptation as a research vessel. As a result, the U. S. Navy created a new class of oceanographic research ships, the AGOR (Utility) class. The first two are presently under construction. An AGOR (U) class ship can be used very well for oceanographic work in the coastal zone. To determine the needs for a coastal zone research vessel in the mid-Atlantic area and its possible configuration, a questionnaire was sent to marine scientists and engineers throughout the area. Results from that questionnaire indicate a definite need for such a vessel. A hull form similar to an offshore supply vessel appears to best fit the needs of the anticipated users.

The paper presents the results from a series of ice model tests performed as part of the DYPIC (Dynamic Positioning in Ice Conditions) research program. DYPIC is a research and development project within the EU’s ERA NET MARTEC project. The major purpose of the DYPIC project is development of equipment and methods for DP Ice Model testing which allows the prediction of station keeping capability of different vessel types and offshore structures under various ice conditions. The first DYPIC model tests performed in 2011 was conducted with two significantly different vessel sizes, a 68.0000 m3 volume displacement arctic drillship and an 8.600 m3 polar research vessel. The model scale was 1/30 for the arctic drillship and 1/18.6 for the Polar Research Vessel. The model tests were performed in the ice model basin at HSVA using vessel models equipped with thruster capacity similar to full scale operation according to DP class 2 / 3 operations. The DP control system was also modified from normal open water DP operations in order to cope with the highly varying ice drift loads acting on the vessel. The test program gave data supporting the development of numerical models of ice loads from managed ice, see reference [6]. The main focus in this paper is on the station keeping performance and associated thrust utilization as a function of varying ice drift loads. The results and data collected in the first year of the DYPIC program demonstrates that DP ice model tests will be a valuable tool for evaluation of vessel performance prior to moving on to full scale arctic DP operations.
