Abstract

Sikkerhetsnett for moonpool er et nett med masker som strekkes over moonpool eller en annen åpning inne i båten og dekker denne. Nettet trekkes over fra den ene eller begge sidene av moonpool, evt. hjørnet. Nettet strekkes til en optimal dekning av moonpool åpningen. Sikkerhetsnett trekkes tilbake til lagrings modus når det ikke er i bruk. Før operasjoner over moonpool startes, kjøres nettene over moonpool og overlapper hverandre.Moonpool safety net is a net with meshes stretched over the moonpool or other opening inside the boat and covers it. The grid is pulled from one or both sides of the moonpool, possibly the corner. The net is stretched to an optimal coverage of the moonpool opening. Safety nets are withdrawn into storage mode when not in use. Before operations over moonpool are started, the networks run over moonpool and overlap.

Description

SIKKERHETSNETT FOR MOONPOLL SAFETY NET FOR MOONPOLL

Det tilveiebringes et sikkerhetsnett for moonpool. Det tilveiebringes nærmere bestemt et sikkerhetsnett for moonpool eller en annen åpning inne i fartøy, som brukt på sjø eller vatn, hvor sikkerhetsnett består av to og flere deler. A safety net is provided for moonpool. More specifically, a safety net is provided for the moonpool or another opening inside a vessel, as used on sea or water, where the safety net consists of two or more parts.

Erfaringer viser at det ved arbeid over moonpool er en fare for at en person kan falle ned i vatn eller fare for å miste ned gjenstand, utstyr. Experience shows that when working above the moonpool there is a risk that a person may fall into water or risk of dropping an object or equipment.

Det er kjent metode å sende redningsfolk ned i vannet for å redde personen som hadde falt ned og den forulykkede skulle kunne reddes opp i horisontal stilling uten for mye fysisk påkjenning. Dette er ikke en optimal situasjon og kan forårsake livsfarlige problemer grunn av bølge, nærhet av utstyr osv. It is a known method to send rescuers into the water to rescue the person who had fallen down and the casualty should be able to be rescued in a horizontal position without too much physical strain. This is not an optimal situation and can cause life-threatening problems due to waves, proximity to equipment, etc.

Dersom den nedmistede gjenstanden kan falle i sjøen, har den potensial til å forårsake skader på brønnutstyr, det ikke mulig å fange det opp igjen, eller prosessen krever store kostnader. If the lost object can fall into the sea, it has the potential to cause damage to well equipment, it is not possible to catch it again, or the process requires large costs.

Fra NO 20101410 og US 9145759 er det kjent fangkurvsystem for en underdekks rørhåndetirngsmaskin. Beskrevet fangkurvsystem til bruk nedenfor en underdekks rørhåndteringsmaskin på en borerigg, hvor fangkurvsystemet innbefatter en fangkurv som er utformet til å holde tilbake en fallende gjenstand som et rør, og hvor fangkurven er forbundet med en konstruksjon på boreriggen ved hjelp av energiabsorberende middel som innbefatter et langstrakt element. From NO 20101410 and US 9145759, there is a known catch basket system for an underdeck pipe handling machine. Described catch basket system for use below a subdeck pipe handling machine on a drilling rig, wherein the catch basket system includes a catch basket designed to retain a falling object such as a pipe, and wherein the catch basket is connected to a structure on the drilling rig by means of energy absorbing means including an elongated element.

Disse er imidlertid er ikke mulig til å bruke ved større åpning og det er fremdeles fare for uhell. However, these are not possible to use with larger openings and there is still a risk of accidents.

Fra US 2008/0283303 A1 er det kjent sikkerhetsnett for en toppdrevet boremaskin som er anordnet over et boredekk, hvor sikkerhetsnett omslutter ulike deler av boremaskin. From US 2008/0283303 A1, a safety net is known for a top-driven drilling machine which is arranged above a drilling deck, where the safety net encloses various parts of the drilling machine.

Disse er imidlertid er ikke mulig til å bruke ved større åpning og det er fremdeles fare for uhell. Det er ikke mulig å bruke den løsning ved behov å ta vekk sikkerhetsnett uten bruk. However, these are not possible to use with larger openings and there is still a risk of accidents. It is not possible to use that solution if it is necessary to remove safety nets without use.

Fra US 9038777 er det kjent sikkerhetsnett for bygninger som består av flere sammensatt deler. Denne løsning er vanskelig å bruke på båten. From US 9038777, safety nets for buildings consisting of several composite parts are known. This solution is difficult to use on the boat.

Formålet med oppfinnelsen er å overvinne eller redusere i det minste en av ulempene ved kjent teknikk. The purpose of the invention is to overcome or reduce at least one of the disadvantages of known technology.

Det tilveiebringes et sikkerhetsnett for moonpool. Det tilveiebringes nærmere bestemt et sikkerhetsnett for moonpool eller en annen åpning inne fartøy, som brukt på sjø eller vatn, hvor sikkerhetsnett består av minimum 2 deler og nettene overlapper hverandre. A safety net is provided for moonpool. More specifically, a safety net is provided for the moonpool or another opening inside a vessel, as used on sea or water, where the safety net consists of a minimum of 2 parts and the nets overlap each other.

Et sikkerhetsnett kan brukes i moonpool av to typer – i moonpoll over vannlinjen og på vannlinjen. A safety net can be used in moonpool of two types – in moonpool above the waterline and on the waterline.

Sikkerhetsnett for moonpool er et nett med masker som strekkes over moonpool eller en annen åpning inne i for eksempel båten og dekker denne. Nettet trekkes over fra den ene eller begge sidene av moonpool, eventuelt hjørne. Nettet strekkes til en optimal dekning av moonpool åpningen. Sikkerhetsnett trekkes tilbake til lagrings modus når det ikke er i bruk. Før operasjoner over moonpool startes, kjøres nettene over moonpool og overlapper hverandre. Safety net for the moonpool is a net with mesh that is stretched over the moonpool or another opening inside, for example, the boat and covers it. The net is pulled over from one or both sides of the moonpool, possibly a corner. The net is stretched to optimal coverage of the moonpool opening. Safety net retracts into storage mode when not in use. Before operations over the moonpool are started, the nets are run over the moonpool and overlap each other.

Nettet kan lett monteres i nybyggde båter og i eksisterende båter. Optimal effekt oppnås ved bruk av nettet bestående av to deler. Ved behov eller ved større åpninger kan effekten oppnås ved bruk av nettet bestående av tre, fire eller flere deler. Nettes masker er av en slik karakter at det fanger opp personer som faller, uten at denne påføres skader, samt fanger opp gjenstander. The net can be easily installed in newly built boats and in existing boats. Optimum effect is achieved by using the net consisting of two parts. If necessary or with larger openings, the effect can be achieved by using the net consisting of three, four or more parts. Nette's masks are of such a nature that they catch people who fall, without them being injured, and also catch objects.

Nettet strammes slik at man unngår trampoline effekten. En viss elastisitet må likevel påregnes. The net is tightened so as to avoid the trampoline effect. A certain elasticity must nevertheless be expected.

Sikkerhetsnett for moonpol kan bestå av to lag som plasseres over hverandre med mellomrom. Øverste lag har bredere masker enn nederste lag, samtidig som øverste lag plasseres så nært som mulig til åpning, hvor det foregår arbeid. En slik to lags utførelse gir mulighet til å fange personer, som ramler ned og reduserer risiko for skader, som kan oppstå ved fall fra høyde. Formålet med øverste lag er kun å fange fallende personer, så det laget kan ha bredere masker. Safety netting for moonpole can consist of two layers that are placed on top of each other at intervals. The top layer has wider meshes than the bottom layer, while the top layer is placed as close as possible to the opening, where work takes place. Such a two-layer design makes it possible to catch people who fall down and reduces the risk of injuries that can occur when falling from a height. The purpose of the top layer is only to catch falling people, so that layer can have wider meshes.

Nederste lag plasseres på en slik avstand fra øverste lag at risiko for skade av å lande på utstyr er minimal. Formålet med nederste lag er å fange fallende gjenstander og utstyr, da er det behov for smalere masker. The bottom layer is placed at such a distance from the top layer that the risk of damage from landing on equipment is minimal. The purpose of the bottom layer is to catch falling objects and equipment, then narrower meshes are needed.

Nederste lag kan festes til øverste lag på kantene og utforme en slags «pose», slik forenkles montering og minimiseres kostander ved bruk av sikkerhetsnett. Da blir nederste lag trekket ut og inn samtidig med øverste lag. Begge lag kan trekkes ut ved bruk av kjent teknikk, for eksempel skinner. The bottom layer can be attached to the top layer on the edges and form a kind of "bag", thus simplifying assembly and minimizing costs when using safety nets. Then the bottom layer is pulled out and in at the same time as the top layer. Both layers can be extracted using known techniques, for example rails.

Det er vanlig at utstyr og verktøy, som brukes på båter, inneholder metall. Sikkerhetsnett for moonpol kan inneholde magnet tråd. Formålet med magnettråd er å minimere tap av utstyr. It is common for equipment and tools used on boats to contain metal. Safety netting for the moon pole may contain magnetic wire. The purpose of magnetic wire is to minimize loss of equipment.
