Description

Vaartuig voor het overzetten van personen of goederen op een offshoreconstructieVessel for transferring persons or goods to an offshore construction

De uitvinding heeft betrekking op een vaartuig voor het overzetten van personen of goederen op een offshoreconstructie, voorzien van een overzetdek.The invention relates to a vessel for transferring persons or goods to an offshore construction provided with a transfer deck.

Een dergelijk vaartuig is bekend uit de praktijk 5 waarin personeel en apparatuur overgebracht moeten worden naar een in zee geplaatste constructie.Such a vessel is known from practice in which personnel and equipment must be transferred to a construction placed in the sea.

Het belangrijkste hierbij in acht te nemen aspect is veiligheid. Dit brengt met zich mee dat het gebruik van een vaartuig voor het overzetten van personeel en apparatuur 10 slechts tot beperkte golfhoogten inzetbaar is. Bij relatief grote golfhoogten is het overzetten van personeel en apparatuur te riskant.The most important aspect to consider here is safety. This implies that the use of a vessel for transferring personnel and equipment 10 can only be used for limited wave heights. At relatively large wave heights, transferring personnel and equipment is too risky.

Ook wordt voor het overzetten wel gebruik gemaakt van een helikopter. Deze zet personeel af door te landen op 15 een helikopterplatform van de offshoreconstructie, dan wel door het personeel met een lier op de offshoreconstructie neer te zetten. Dit is echter een dure methode die ook niet van gevaar is ontbloot.A helicopter is also used for transferring. It sends personnel off by landing on a helicopter platform of the offshore construction, or by placing the personnel with a winch on the offshore construction. However, this is an expensive method that is not without danger.

Uit US-A-4.854.800 is een vaartuig bekend welke 20 voorzien is van een draagtoestel voor het overzetten van goederen naar een andere inrichting en waarbij het draagtoestel ruimtelijk stabiel gehouden kan worden onafhankelijk van de bewegingen van het vaartuig waarop het draagtoestel is gemonteerd.US-A-4,854,800 discloses a vessel which is provided with a carrier device for transferring goods to another device and wherein the carrier device can be kept spatially stable independently of the movements of the vessel on which the carrier device is mounted.

25 Uit US-B-6.659.703 is eveneens een op een vaartuig gemonteerd gestabiliseerd platform bekend waarmee personen op een andere inrichting kunnen worden geplaatst. Het platform uit US-B-6.659.703 wordt daarbij in hoofdzaak stationair gehouden ten opzichte van bedoelde inrichting waarop de perso-30 nen dienen te worden overgezet.US-B-6,659,703 also discloses a stabilized platform mounted on a vessel with which persons can be placed on another device. The platform from US-B-6,659,703 is thereby held substantially stationary with respect to the said device to which the persons are to be transferred.

Met de uitvinding is beoogd een vaartuig te verschaffen waarmee op een veilige manier personeel en apparatuur op een offshoreconstructie kan worden afgezet onder handhaving van de daarbij in acht te nemen veiligheidseisen. 35 Het vaartuig volgens de uitvinding is daartoe voor- 2 zien van een in stand regelbaar platform dat op het overzet-dek is geplaatst, en dat afsteunt op zes hydraulische regel-cilinders die op het overzetdek zijn gemonteerd. Een dergelijk platform met zes hydraulische regelcilinders zoals ge-5 toond in de tekening staat ook wel bekend als Stewart-platform.The object of the invention is to provide a vessel with which personnel and equipment can be deposited in a safe manner on an offshore construction while maintaining the safety requirements to be observed. To this end, the vessel according to the invention is provided with a position-adjustable platform which is placed on the transfer deck and which rests on six hydraulic control cylinders mounted on the transfer deck. Such a platform with six hydraulic control cylinders as shown in the drawing is also known as the Stewart platform.

Met het vaartuig volgens de uitvinding is het mogelijk het platform zodanig stabiel in stand te regelen dat personen of goederen eenvoudig via een loopplank vanaf het 10 platform de offshoreconstructie kunnen bereiken.With the vessel according to the invention it is possible to stably position the platform in such a way that persons or goods can easily reach the offshore construction via a gangway from the platform.

Een en ander kan effectief zo worden gerealiseerd door het vaartuig volgens de uitvinding te voorzien van bewe-gingssensoren voor het meten van de vaartuigbewegingen, en een op de bewegingssensoren aangesloten regelsysteem dat stu-15 rend gekoppeld is met de hydraulische regelcilinders voor het in afhankelijkheid van de vaartuigbewegingen verstellen van de stand van het platform.All this can be effectively realized in this way by providing the vessel according to the invention with movement sensors for measuring the vessel movements, and a control system connected to the movement sensors which is connected to the hydraulic control cylinders for dependence on adjust the vessel movements from the position of the platform.

De uitvinding zal in het navolgende verder worden toegelicht aan de hand van een de aangehechte conclusies niet 20 beperkend uitvoeringsvoorbeeld en onder verwijzing naar de tekening.The invention will be further elucidated hereinbelow on the basis of an exemplary embodiment not appended to the appended claims and with reference to the drawing.

De tekening toont in een enkele figuur een zeer schematische weergave van het vaartuig volgens de uitvinding.The drawing shows in a single figure a very schematic representation of the vessel according to the invention.

De enkele figuur van de tekening toont schematisch 25 een offshoreconstructie 1 welke voorzien is van een werkplat-form 2. Verder toont de figuur het vaartuig 3 volgens de uitvinding waarmee personen of goederen op het werkplatform 2 van de offshoreconstructie 1 dienen te worden gebracht. Uiteraard is ook het afhalen van personen of goederen een met 30 het vaartuig volgens de uitvinding beoogde activiteit.The single figure of the drawing schematically shows an offshore construction 1 which is provided with a working platform 2. Furthermore, the figure shows the vessel 3 according to the invention with which persons or goods must be brought onto the working platform 2 of the offshore construction 1. Naturally, the collection of persons or goods is also an activity intended with the vessel according to the invention.

Het vaartuig 3 volgens de uitvinding bezit een overzetdek 4 waarop een in stand regelbaar platform 5 is aangebracht .The vessel 3 according to the invention has a transfer deck 4 on which a position-adjustable platform 5 is arranged.

Het platform 5 steunt daartoe af op in het getoonde 35 geval zes hydraulische regelcilinders 6 die op het overzetdek 4 zijn gemonteerd.To that end, the platform 5 is supported on six hydraulic control cylinders 6 mounted on the transfer deck 4 in the case shown.

Verder is voorzien in bewegingssensoren 7 voor het meten van de bewegingen van het vaartuig 3 en een op de bewegingssensoren 7 aangesloten regelsysteem 8 dat sturend gekop 3 peld is met de hydraulische regelcilinders 6 voor het in afhankelijkheid van de bewegingen van het vaartuig 3 verstellen van de stand van het platform 5.Furthermore, movement sensors 7 are provided for measuring the movements of the vessel 3 and a control system 8 connected to the movement sensors 7, which is steered to the hydraulic control cylinders 6 for adjusting the movement of the vessel 3 in dependence on the movements of the vessel 3. position of the platform 5.

Met de hiervoor toegelichte middelen kan het plat-5 form 5 in een in hoofdzaak stationaire stand worden geregeld, waarbij het overzetten van personen of goederen naar het werkplatform 2 van de offshoreconstructie 1 veilig en snel en eenvoudig kan verlopen, bijvoorbeeld door gebruikmaking van een tussen het platform 5 en het werkplatform 2 aangebrachte 10 loopplank. Dit laatste is in de figuur niet getoond, maar is voor de vakman geheel duidelijk zodat van het tonen daarvan kan worden afgezien.With the means explained above, the platform 5 can be controlled in a substantially stationary position, wherein the transfer of persons or goods to the working platform 2 of the offshore structure 1 can proceed safely and quickly and easily, for example by using an intermediate gangway arranged on the platform 5 and the working platform 2. The latter is not shown in the figure, but is entirely clear to the person skilled in the art so that displaying it can be dispensed with.
