In this experimental study some measurements and their analysis are presented concerning the polluted water effluent disposal in the sea water. The wastes are disposed through the round openings of a submerged in the sea diffuser, in the form of turbulent jets which are mixing (diffusing) with the sea water. Three inclination angles (to the vertical) of the jets are examined, ö=15°-45°-75°, and at any angle three Froude numbers are also examined, Fro=4.8-17-25.3. The results are combined with previous results by the author for 90°≤φ≤150°.

ABSTRACT Unmanned submarine commonly called Autonomous Underwater Vehicle (AUV) is one type of underwater robots used for underwater mapping. AUV is an underwater vehicle capable of automatically moving in water, controlled by humans on vessel. To build AUV is not easy as many components play important roles in the operation of AUV, one of which is active ballast. Calculations on the making and benchmarks of active ballast systems are still very rare. Active ballast is a set of equipment used to fill its tanks with seawater and to empty sea water from the tanks on submarines. These tanks are intended to balance submarines and for active ballast systems on submarines so as to be able to dive and float as needed. In this paper an experimental study was carried out on a tube resembling AUV with both fresh water and sea water to obtain ballast volume in AUV.  Keywords: AUV, Active ballast, Experimental study

The offshore activities in cold waters have moved from shallow to deep sea waters, which require different operations as compared to activities in hot sea water. Such offshore operations in cold regions like arctic may be effected by the ice accretion on deck and other areas of structure. Ice mainly accretes from both sea spray and atmospheric icing, which can create problems for operational environment and safety of people working on offshore structures in cold regions. In this research a lab based experimental study has been carried out to preliminary design and test an intelligent thermal anti/de-icing system. The experimental study was carried out in cold room chamber of Narvik University College, where temperature can be well controlled between +10 to-30 °C. The proposed intelligent thermal based deicing system can be used to control the communication between icing sensors, weather station, heating devices and central control unit. In this preliminary design phase, a simple surface temperature control method has been developed and tested that can further provides an efficient thermal deicing method and will also be capable to control the surface temperature of objects of interest in cold regions
