Description

Title: Illumination System; Offshore platform
The invention relates to an illumination system for offshore platforms, typically for constructions at an offshore site comprising a plurality of illumination units.
Offshore platforms, or offshore constructions in general, usually comprise at least one illumination system. An illumination system comprises a plurality of illumination units, wherein an illumination unit comprises at least one light emitting element mounted in a housing. For example perimeter hghts on a hehdeck may form an illumination system, or the Touchdown/Positioning Marking Circle and illuminated H on a hehdeck may form an illumination system, or the corner hghts of an offshore platform may form an illumination system, or the staircase and/or passage hghts on an offshore site may form an illumination system.
Typically, the illumination units of the illumination system are powered individually. This means a lot of cabhng, a lot of components e.g. terminals, etc. Installation of such an illumination system is relatively complex, requiring relatively much time of workmen to install the illumination units on the offshore site mainly manuahy. A drawback of the conventional system is that the installation is relatively complex, time consuming and sensitive to errors. Also, when the ihumination units are installed in series, a mistake at some position may lead to failure in the whole system. Or, when the illumination units are installed in parallel, additional cabhng and/or connections may be required, thereby increasing installation time and/or failure sensitivity.
It is an object of the invention to provide for an illumination system for offshore constructions that obviates at least one of the above mentioned drawbacks. In particular, reducing the installation time and/or the error-sensitivity may be aimed for.
Thereto, the invention provides for an illumination system according to claim 1.
By providing a contactless transmission of the power from the power cable to the illumination unit, complex and/or time consuming connections from the cabling to the illumination unit may be obviated thereby reducing the installation time. Also, risks on erroneous connections may be reduced. The transmission of the electrical power from the power cable to the receiving illumination unit is contactless, meaning that the electrical conductor is not as such connected to the illumination unit as to provide an electrical connection with the illumination unit. Connectors, terminals, glands, connecting elements, cable plugs etc. may thus be omitted.
Advantageously, the power transmission from the power cable to the illumination unit is obtained by means of induction.. In another embodiment, the contactless energy transmission may be obtained via a capacitive coupling between the electrical conductor and the receiving illumination unit.
In an embodiment, a sleeve of the power cable may shield the power cable from environmental influences, damages during handling and/or use, etc. Advantageously, the sleeve may have an external surface that is configured to cooperate with a housing of an illumination unit as to fit the illumination unit uniquely on the sleeve. By providing a shape of the sleeve that cooperates with the housing of the illumination unit, e.g. to provide for a form-closed fit, or an other cooperation, mounting of the illumination unit may be facilitated, thereby installation time and/or installation errors may be reduced.
In another embodiment, additionally a data communications cable may be provided between the illumination units. The transmission of data between the illumination unit and the data cable may be contactless. The data communications cable may be provided as a separate cable having an own protective sleeve, or may be provided in the same sleeve as the power cable. In another embodiment, the data communication may be via the power cable present between the illumination units, e.g. the data communication signals may be superimposed on the power cable.
The invention further relates to a method for installing illumination units on an offshore platform, to an offshore platform provided with an illumination system, and to an offshore helideck provided with such an illumination system.
Further advantageous embodiments are represented in the subclaims.
The invention will further be elucidated on the basis of exemplary embodiments which are represented in a drawing. The exemplary embodiments are given by way of non-limitative illustration.
In the drawing:
Fig. 1 shows a schematic perspective view of a first embodiment of an illumination system;
Fig. 2 shows a schematic perspective view of a second embodiment of an illumination system;
Fig. 3 shows a schematic perspective view of a third embodiment of an illumination system;
Fig. 4 shows a schematic top view of an offshore helideck provided with an illumination system for perimeter fighting.
It is noted that the figures are only schematic representations of embodiments of the invention that are given by way of non-limiting example. In the figures, the same or corresponding parts are designated with the same reference numerals.
Figure 1 shows a schematic perspective view of an illumination system 1. The illumination system 1 comprises at least one illumination unit 2 and a power cable 3. The illumination system 1 generally comprises a plurality of illumination units 2. For reasons of simplicity only a single illumination unit 2 is shown here. Also, for reasons of simplicity, the illumination unit 2 is shown here very schematically, but it is to be understood that the illumination unit 2 can be a perimeter light, or an obstacle hght, or a flood light, or a gangway light etc. Preferably, the illumination system 1 comprises a plurality of the same illumination units 2, as to form a circuit of connected illumination units, for example a system of perimeter lights, wherein the subsequent perimeter lights form a circuit of connected perimeter lights. The illumination units 2 thus are connected by means of the power cable 3.
Each illumination unit 2 comprises a hght emitting element 4 which is arranged in a housing 5. The hght emitting element 4 can be an LED-element, or an incandescent hght emitting or any other hght emitting element. The housing 5 can be a bracket or a base, etc. in which the hght emitting element 4 can be mounted. The illumination unit 2 may further comprise additional components, such as a cover to protect the hght emitting element, or mounting brackets to mount the illumination unit fixedly to an underground, or a circuit board on which a control system may be arranged to control the hght emitting element, etc. Many variants of the illumination unit 2 are possible, depending on the application type.
Advantageously, the power cable 3 is installed on the offshore structure, e.g. fixed or mobile offshore platform, or a helideck. The power cable 3 may be installed along the positions at which the illumination units may be located. The power cable 3 may be installed along a track passing the said positions.
Then, the illumination units 2 may be mounted over the power cable at the said positions. Alternatively, the ihumination units 2 may be mounted over the power cable 2 at random positions.
Figure 1 shows a first embodiment of an ihumination system 1 allowing the ihumination unit 1 to be mounted at random positions along the power cable 3 and/or at predetermined positions. The illumination unit 2 comprises a coupling element 6 to couple with the power cable 3. The coupling element 6 is here shown as a recess in a bottom of the illumination unit 2. For example, the recess may be formed to receive the power cable 3 and to clamp the power cable 3 firmly as to provide for a fixed coupling between the power cable 3 and the illumination unit 2. The coupling element 6 may have various embodiments. For example, in addition to the recess provided, a closing element (not shown) may be provided to close the recess once the cable 3 is being mounted into the recess.
Here, the power cable 3 is a relatively simple power cable 3 comprising an outer sleeve 7 and a conductor 8 in the sleeve, here two conductors 8 are shown. A power cable 3 may comprise a plurality of conductors, or may comprise a single conductor. Multiple variants are possible. Alternatively, multiple power cables may be provided of which each power cable comprises a single conductor and each power cable may be comprised in its own sleeve. In another embodiment, multiple power cables may be comprised in the same sleeve.
In the embodiment of figure 2, both the power cable 3 and the illumination unit 2 are provided with a coupling element 6a’, 6b’. The outer sleeve 7 of the power cable 3 is shaped as to fit in a corresponding recess 6’ of the illumination unit 2. The shape of the outer surface of the outer sleeve 7 of the power cable 3 may be considered as a first coupling element 6b’. The recess 6a’ of the illumination unit 2 can be considered as the second coupling element 6a’. The first and the second coupling elements 6a’, 6b’ correspond with each other as to fit into each other. By providing an un-round shape of the outer sleeve 7 the illumination unit 2 may be fit uniquely over the power cable 3 thereby further reducing installation errors. The coupling elements 6 may have various embodiments, e.g. a form coupling as in figure 2, or a clamping coupling, or a hook coupling etc.
In the embodiment of figure 3 a further coupling element 6b” is shown. Here, the power cable 3 is provided with a base 9. Bases 9 can be provided at predetermined distances along the power cable 3, at regular intervals or at irregular intervals. Bases 9 may be fixedly mounted to the power cable 3, e.g. integrated with the outer sleeve 7 of the power cable 3, or can be mounted removable and/or shdingly onto the power cable 3. By providing the base 9 shdingly on the power cable 3, the position can be adjusted with respect to the power cable 3. By providing the base 9 removable with respect to the power cable 3, the base 9 may be mounted over the power cable 3 after installation of the power cable 3 onto the offshore structure. Also, in case of failure e.g., the base can be exchanged and can be replaced by a spare one. On the base 9, the coupling element 6b” may be provided to couple with the illumination unit 2. The coupling element 6b” may have various embodiments, and the form and shape thereof are not limited to the embodiments shown here. For example, instead of a separate coupling element provided on the base, the base itself may be configured as a coupling element to couple with the illumination unit. The illumination unit may be provided with a coupling element to couple with the coupling element of the power cable.
In the embodiment of figure 4, an example is shown of a power cable 3 arranged onto a hehdeck of an offshore structure 10 and some illumination units 2, e.g. perimeter fights, mounted over the power cable 3. The power cable 3 may be mounted on the deck or below the deck. The illumination units 2 may then be mounted over the power cable 3. For example, when the power cable 3 is arranged on the deck, the illumination units 2 can be fit over the power cable 3 and then may be fixed to the deck in a conventional way, e.g. by means of screws or clamps. When the power cable is fit below the deck, an opening may be provided at predetermined positions through which for example a coupling element of the illumination unit may fit to couple with the power cable. The illumination unit 2 may then for example be connected to the deck.
For the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments, however, it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.
Many variants will be apparent to the person skilled in the art. All variants are understood to be comprised within the scope of the invention defined in the following claims.
