Abstract
Foreliggende oppfinnelse vedrører en merd for oppdrett, oppbevaring eller transport av fisk i sjø, nærmere bestemt helt eller delvis i utaskjærs havområder, der · merden kan senkes ned i vannmassene etter behov til en ønsket dybde, der merden kan heves til halvt eller tilnærmet halvt neddykket tilstand for ulike arbeidsoperasjoner som vedlikehold og inspeksjon av merden eller innhøsting, der merden har en hovedsakelig kuleformet geometri. Oppfinnelsen er særpreget ved at merden består av et rammeverk av stag (1, 2, 3, 4) som hovedsakelig omfatter polyetylen eller polyetylen-liknende materialer, for eksempel PolyEtylen Low Density (PELD) eller PolyEtylen High Density (PEHD), fortrinnsvis PEHD, en gjennomgående horisontal senterstolpe 5 som i tillegg til et bæreelement fungerer som et oppdriftsregulerende element for heving og senking av merden, en hesteskoformet arbeidsplattform 6 med integrert dokke 7 for arbeidsfartøy, hvor hele arbeidsplattformen med dokke kan heves og senkes vha. oppdriftsregulering gjennom et eget element 13, og hvor arbeidsdekket er innfestet på en forlenget aksel 15 på senterstolpen, slik at merden kan roteres på innsiden av det nevnte arbeidsdekket. På nevnte aksel er det også festet blåser 10 gjennom liner 8, som gir merden tilstrekkelig restoppdrift i normal flyteposisjon, og hvor loddene 9 plasseres på havbunnen når merden skal stabiliseres helt nedsenket på en gitt dybde; alternativt at merden stabiliseres på ønsket dybde pga. restoppdriften i oppdriftsenheten 30 og oppdriftselementet 23, som vist på fig. 30. Livgivende funksjoner som for, energi og luft tilføres merden gjennom en livline fra en oppdriftsenhet 30 like ved, fortrinnsvis en plattform som er en integrert del av merdens forankring.BACKGROUND OF THE INVENTION The present invention relates to a cage for fish farming, storage or transport of fish in the sea, in particular wholly or partially in the shallow waters, where the cage can be lowered into the water bodies as required to a desired depth, where the cage can be raised to half or almost half submerged. condition for various work operations such as maintenance and inspection of the cage or harvest, where the cage has a mainly spherical geometry. The invention is characterized in that the cage consists of a framework of braces (1, 2, 3, 4) which mainly comprises polyethylene or polyethylene-like materials, for example PolyEtylene Low Density (PELD) or PolyEtylene High Density (PEHD), preferably PEHD, a continuous horizontal center post 5 which, in addition to a support element, acts as a buoyancy regulating element for raising and lowering the cage, a horseshoe-shaped work platform 6 with integrated dock 7 for work vessels, the entire working platform with dock can be raised and lowered using. buoyancy control through a separate element 13, and wherein the working deck is mounted on an extended shaft 15 on the center post, so that the cage can be rotated inside the said working deck. On said shaft, blower 10 is also secured through liner 8, which provides the cage with sufficient residual buoyancy in the normal flow position, and where the solder 9 is placed on the seabed when the cage is to be fully submerged at a given depth; alternatively, the cage is stabilized at the desired depth due to. the residual buoyancy in the buoyancy unit 30 and the buoyancy element 23, as shown in FIG. 30. Life-giving functions such as lining, energy and air are supplied to the cage through a lifeline from a buoyancy unit 30, preferably a platform which is an integral part of the cage's anchorage.
