Description

Anordning for forskyvning av utstyr ombord i skip, særlig boreskip. Device for moving equipment on board ships, especially drilling ships.

Oppfinnelsen vedrører en anordning for forskyvning eller forflytning av utstyr ombord i skip, særlig boreskip, ved hjelp av en horisontal transportør, med en del av utstyret anordnet under vannflaten. The invention relates to a device for displacing or moving equipment on board a ship, in particular a drilling vessel, by means of a horizontal conveyor, with part of the equipment arranged below the water surface.

Ombord i boreskip har man stabilitetsproblemer som opp-står når tungt utstyr skal beveges horisontalt. On board drilling ships, there are stability problems that arise when heavy equipment has to be moved horizontally.

I denne forbindelse er nivået til boreplattformen en gitt faktor, og man kan ikke tillate at arbeidsplattformen rundt kjellerdekkåpningen blir liggende under skipets lastelinje. Det er i dag vanlig å demontere utblåsningshindreren ,4. kjellerdekkåpningen, dvs. å dele utblåsningshindreren opp i to eller flere deler når den skal lagres og/eller inspiseres, idet utblåsningshindreren settes sammen igjen i kjellerdekkåpningen. Dette er en meget tidskrevende og dyr fremgangsmåte og i løpet av denne tiden vil boreskipet være ute av drift med hensyn til boreoperasjoner, hvilket er meget uørfsket, på grunn av de høye driftsomkostninger. In this connection, the level of the drilling platform is a given factor, and one cannot allow the working platform around the basement deck opening to lie below the ship's load line. It is common today to dismantle the blow-out preventer, 4. the basement deck opening, i.e. to split the blowout barrier into two or more parts when it is to be stored and/or inspected, the blowout barrier being reassembled in the basement deck opening. This is a very time-consuming and expensive procedure and during this time the drilling ship will be out of service with respect to drilling operations, which is very undesirable, due to the high operating costs.

Foreliggende oppfinnelse tar sikte på å løse de proble-mer som man støter på i denne forbindelse. Ifølge oppfinnelsen er det derfor tilveiebragt en anordning som nevnt innledningsvis, hvilken anordning er kjennetegnet ved at det er truffet tiltak for å holde konstruksjonen som er anordnet over transportørbanen på det lavest mulige nivå, og det er også truffet tiltak for å kunne transportere det tunge utstyr uten eller bare med delvis demontering. The present invention aims to solve the problems encountered in this connection. According to the invention, a device has therefore been provided as mentioned in the introduction, which device is characterized by the fact that measures have been taken to keep the structure arranged above the conveyor track at the lowest possible level, and measures have also been taken to be able to transport the heavy equipment without or only with partial disassembly.

På denne måten kan man redusere forsinkelsene for bore-operas jonene ved inspeksjon, prøving og/eller utbytting av utblåsningshindreren. In this way, the delays for the drilling operations can be reduced when inspecting, testing and/or replacing the blowout preventer.

Oppfinnelsen skal forklares nærmere under henvisning til tegningene, hvor The invention shall be explained in more detail with reference to the drawings, where

A watertight door is denoted by 2. The heavy equipment to be moved is denoted by 3- A horizontal slide is denoted by 4. The basement deck opening is denoted by 5*the working deck is denoted by 6, an upper support structure is denoted by 7,

en nedre bærekonstruksjon er betegnet med 8, og boreskipets vannlinje er betegnet med 9» a lower support structure is denoted by 8, and the drill ship's waterline is denoted by 9"

Ombord i boreskipet er det tilveiebragt et rom 1 (neddykket dekk), hvis bunn ligger under boreskipets vannlinje. Det er anordnet en eller flere vegger, med vanntette dører 2. Ved å slippe vann inn i rommet og åpne en eller flere av veggene kan det tunge utstyr 3, som befinner seg delvis under vannflaten, transporteres langs de horisontale baner 4, mellom den fri vann-flate utenfor skipet og rommet 5 (kjellerdekkåpningen) inne i skipet, hvilken åpning er omgitt av skipskonstruksjonen. On board the drilling vessel, a room 1 (submerged deck) is provided, the bottom of which lies below the drilling vessel's waterline. One or more walls are arranged, with watertight doors 2. By letting water into the room and opening one or more of the walls, the heavy equipment 3, which is partially below the water surface, can be transported along the horizontal tracks 4, between the free water surface outside the ship and room 5 (the basement deck opening) inside the ship, which opening is surrounded by the ship's structure.

Etter at det tunge utstyr er bragt inn i eller ut av rommet kan veggen eller veggene lukkes vanntett, og rommet kan så tørrpumpes. After the heavy equipment has been brought into or out of the room, the wall or walls can be closed watertight, and the room can then be dry pumped.
