Description
Loading deck for a vessel, and method of installation of said loading deck
The present invention relates to a loading deck for a vessel. More specifically, the invention relates to a loading deck for a vessel, and a method for installation of the 5 loading deck, as stated in the introducing part of claims 1 and 10, respectively.
Platform supply vessels transport increasingly numbers of increasingly lighter containers, and lack of loading space is thus often a problem. This is especially apparent during loading and unloading at offshore installations. Q
The present invention aims at solving the above and other problems by providing a solution which makes the vessels more efficient load carriers. In a time troubled by lack of vessels and crew and with high operation costs it is profitable both for the environment, the shipping company and the end user to be able to use vessels withs larger capacity. In addition, an advantageous embodiment of the invention provides a solution for improved launching of rescue vessels, so-called MOB boats or FCRs (Fast Rescue Crafts) from said vessel, and transport of rescued, injured persons to the ward of said vessel. Q The loading deck according to the invention is intended both to be integrated on new vessels and to be retrofitted on existing vessels.
As to prior art US 3889621 Al should be mentioned, in which it is described a carriage or pier running on rails on top of the railing on the loading deck of a tugboat. The5 carriage is mobile in the length direction of the vessel for anchor handling, and also incorporates a crane arranged as a traverser carriage which is able to run transversely of the carriage and thus also the vessel for moving load on the deck arranged below. It is not known from this publication to use such a carriage as a loading deck, nor is it known to arrange a MOB boat garage on a carriage on the railing. 0
The loading deck and the method according to the invention are characterized by the features as stated in the characterizing clause of claims 1 and 10, respectively.
Advantageous embodiments of the invention appear from the dependent claims. 5
The present invention is explained in more details in the following, by referring to a non-limiting embodiment and to the enclosed drawings, wherein
figure 1 shows a platform supply vessel belonging to the applicant with a conventional deck solution,
figure 2 shows the vessel of figure 1 fitted with a loading deck according to the invention, in side elevation view,
figure 3 shows the vessel in figure 2 in top elevation view,
figure 4 shows the vessel in figures 2 and 3 in rear view,
figure 5 shows the loading deck in figures 2 to 4 in three predetermined positions, in which the loading deck is arranged in a middle position while the front and rear position are indicated by dotted lines,
figure 6 is an enlarged side elevation view of the loading deck and its adjacent constructions as shown in figures 2 to 4, and
figure 7 shows a partial sectional view of a guiding arrangement or means for the loading deck according to the invention.
By referring to figure 1 it is shown a platform supply vessel of the type Ulstein PX 105 belonging to the applicant with a conventional, immobile loading deck 4 and a conventional solution for launching of a MOB boat.
By referring to figures 2 to 6 a corresponding platform supply vessel 1 is shown, fitted with a mobile loading deck 2 according to the invention, which for the solution as shown increases the total loading deck area by 220 m2 or 22 %. The invention thus relates to a solution which increases the loading deck area of vessels having capacity reserves but lacking space for load on deck.
hi addition to the advantages by having a larger loading capacity as initially stated, and in advantageous embodiments also MOB boat operations and transport of injured, picked-up persons as it will be explained in more details in the following, a MOB boat garage 3 could function as a safety cage for crew working on the loading deck 2 during loading and unloading. Further, the loading deck 2 could function as a mobile shelter deck for sheltering load on the conventional immobile deck 4 of the vessel.
As initially stated, the loading deck 2 can also be retrofitted on existing vessels in order to achieve one or more of the advantages as stated above.
By additionally referring to figure 7 the loading deck 2 according to the invention comprises guiding means 5 and not depicted driving means for movement of the loading deck 2 in the longitudinal direction of the vessel 1 between a front 6 and a rear 8 end position on the vessel, wherein the mobile loading deck 2 is arranged above the immobile deck 4 of the vessel 1 in order to provide an increased total deck area of the vessel 1. A suitable velocity of movement of the loading deck 2
As shown the conveying means 5 incorporates a number of substantially vertically arranged 9 and horizontally arranged 10 bogies having wheels 11 arranged along the longitudinal sides of the loading deck 2 for cooperation with the cargo rails 12 of the vessel, wherein the substantially horizontally arranged bogies 10 take up substantially horizontal pressure for example caused by rolling movements of the vessel 1, and wherein the substantially vertically arranged bogies 9 take up substantially vertical pressure from the loading deck 2 and load arranged on said loading deck.
A person skilled in the art will in a simple way be able to choose said not depicted driving means in elucidation of the present description, and it can for example comprise a pull winch with redundancy, a winch of the rack and pinion type or a drive chain arranged on at least one side of the vessel 1, said driving means preferably being hydraulically or electrically driven.
The loading deck 2 can preferably be locked in three predetermined positions 6, 7, 8 by means of not shown locking bolts inserted in the cargo rails 12, for thus being securely locked during transport of said vessel 1.
The bogie wheels 11 of the loading deck 2 are preferringly maintenance-free composite wheels. The substantially horizontally arranged bogies 10 are fixed to the loading deck 2 as the substantially horizontally arranged bogie wheels 11 can only rotate around their wheel axles for guidance along the cargo rail 12. Further, the substantially vertically arranged bogies 9 are pivotally arranged in a plane orthogonally of the longitudinal direction of the cargo rail 12, and thus also of the vessel 1, in addition to the fact that said substantially vertically arranged bogie wheels 11 can rotate around their wheel axles for guidance along the cargo rail 12. The reason for the pivotal arrangement of the
vertical bogies 9 is to, if necessarily, be able to compensate for yielding, tolerances, etc. resulting in non-linearity of the cargo rails 12.
On a bracket 14 for fixation of the substantially horizontally arranged bogie a sliding rail 15 is preferably provided below a surface 16 of the cargo rail 12 or, as depicted herein, a square tube 18 arranged to the cargo rail 12, for securing the loading deck 2 to the cargo rail 12.
A not depicted control system, in combination with not depicted position indicators, preferably make sure that the locking bolts are automatically actuated when the loading deck is moved into one of the three predefined positions 6, 7, 8.
Access to the loading deck 2 is advantageously made via starboard cargo rail via a separately arranged, not depicted platform or via a MOB boat garage 3 arranged on the port side of the loading deck 2.
A middle 7 of said three predetermined positions of the loading deck 2 is preferably close to the buoyancy centre of the vessel 1 where the movements of the vessel are the calmest, in order to safeguard a gentle pick-up of injured persons during bad weather, and MOB boat operations in general.
The front or forward 6 of said three predetermined positions 6, 7, 8 of the loading deck 2 is preferably directly adjacent to the ward of said vessel 1, for direct transport of injured persons to the ward from said middle position 7 of the loading deck 2.
Not depicted floodlights and cameras are advantageously arranged below the loading deck 2 in order to safeguard that sight and illumination conditions on that part of the immobile deck 4 of the vessel 1 which at any time is covered by the loading deck 2 is at least as good as for a conventional vessel 1 without the loading deck 2 according to the invention.
Installation of a loading deck 2 according to the invention on a ship 1 is advantageously made in the following three steps:
- installation of the cargo rails 12 - installation of the loading deck 2
- installation of the driving means (hydraulic or electric)
The square tubes 18 on which the wheels are running are fixed by welding after the cargo rail 12 is being installed and welded to the vessel.
When the cargo rails 12 with square tubes 18 have been fixed the loading deck 2 itself 5 can be lifted in place, with the substantially vertical bogies 9 and bogie wheels 11 mounted to the loading deck 2.
When the loading deck 2 have been placed on the cargo rails 12 the substantially horizontal bogies 10 and bogie wheels 11 including brackets 14 and sliding rails 15 cano be fixed.
During the mounting it is important that tolerance requirements are complied with and that deformations are avoided, as it is evident that a failing loading deck 2 might endanger both lives and load, and also result in capsizing and loss of the vessel as such.s
Even if the present invention primarily relates to a loading deck, it is also conceivable, within the scope of the invention, to have a pure MOB boat solution in which said mobile deck is designed as a small traverse solution which is not intended for placement of load thereon but in which a MOB boat is arranged on the one, alternativelyQ on both, sides of the deck, and with or without any accompanying garage.
