Abstract

En fiskemerd som kan senkes og heves igjen, kan vare utstyrt med en eller flere flyteringer som er helt eller delvis hul innvendig, og som har ventiler for inntak og utløp for vann, og innblåsning og uttak av luft, og som har innmontert tette eller perforerte skillevegger i flytaringene. Det nye ved fiskemerden er at to hovedskillevegger deler minst en av flyteringene på en slik måte at den består av en største horisontal sektor A og en mindre horisontal sektor B. Dermed kan den største sektoren av fiskemerdens flytering åpnes slik at vannet strømmer fritt inn i flyteringen samtidig som luften presses ut gjennom ventilene som står nær sektor B og holdes høyest i vannskorpen av sektor B. Fiskemerden kan henge på sektor B alene. Når del A har sunket, kan man foreta en balansert, kontrollert senkning ved å åpne ventilene i sektor B. Ved heving blåses sektor B først og kommer til overflaten. Deretter kan den største sektor A blåses tom for vann, og merden flyter igjen.
