Abstract
A seabed positioned subsea installation comprise processing equipment. The subsea installation is provided with at least one guide way and at least one manipulator device. The base of the manipulator device is movably attached to the at least one guide way, and the subsea installation further comprises a frame extending over the processing equipment.
Description
- This invention relates to a manipulator device for operation of a subsea installation and its processing equipment. More particularly the invention relates to a manipulator device which is permanently installed on a subsea installation to be able to carry out subsea inspection, maintenance, modification and surveillance of the subsea installation and its processing equipment.
- The petroleum industry applies an increasing number of remotely controlled subsea installations for production of oil and gas. These are partly placed at great ocean depths. In order to be able to carry out inspection, maintenance and repair work on such installations, and also assist in well intervention, that is work to be carried out in the well, intervention vessels are used. For help in this work, remotely controlled vessels, so-called ROVs, operated by an operator on the support ship on the surface, are also used. The intervention vessel can also be the support vessel for the ROV. The support vessel with the ROV must be mobilised to the right place, and it takes time to manouvre the ROV from the surface down and back up, and as there might be poor weather conditions, the support vessel/intervention vessel might remain waiting. This might lead to various types of operational deviations and increased risk. Work to be carried out on such installations might therefore be unfortunately time consuming compared to the weather windows available, with the extra costs this results in. The problem is intensified by the typical lack of adapted intervention vessels to operate subsea installations of this type. Thus alternative technology that strongly contributes to reducing vessel time on the individual installation, will be both cost saving and risk reductive.
- Work tasks carried out by an ROV in connection with well interventions on a subsea installation, might for instance be to prepare the subsea installation before the well intervention tool is led from the intervention vessel to the wellhead. Such work might comprise of opening of gates in the subsea installation over the wellhead, closing of valves and opening of valves. Similar work, but in the opposite order, can be carried out after completion of the well intervention. The ROV is also used for carrying out subsea inspection, maintenance, modification and surveillance of the subsea installation and its processing equipment.
- In some jurisdictions it is an official requirement that subsea installations are provided with a protective frame extending over the subsea installation. The frame can protect against trawling so that the subsea installation is so-called over-trawlable. The frame can also protect the subsea installation and its processing equipment against for instance anchors and objects failing overboard from a vessel that is above the subsea installation.
- Patent document NO 160736 discloses a subsea installation without a protective frame over the subsea installation. The subsea installation is provided with elongated rails. A rather big, loadbearing, attended autonomous subsea vessel can be led over the installation and be positioned upon the rails with legs protruding down from the subsea vessel. The subsea vessel can move sideways along the rails on the down-protruding legs. The subsea vessel is not arranged to be able to carry cut work on a subsea installation provided with a protective frame over the subsea installation.
- Patent document NO 160736 discloses a subsea installation with a protection fender, but without any protective frame over the subsea installation. The subsea installation is in its lower part provided with a rail inside of the protection fender and which surrounds the production collecting pipes. A buoy is released from the rail and pulls with it a line up to the surface. A manipulator can be lowered down to the subsea installation by pulling itself down along the line to meet the rail, and it is movably attached upon the rail. The manipulator can carry out various types of work tasks on the subsea installation. Patent document NO 139323 also discloses a subsea installation without any protective frame over the subsea installation. The subsea installation is in its lower part provided with rails encircling the subsea installation. A buoy is released from the rails and pulls with it a line tip to the surface. A manipulator can be lowered down to the subsea installation by pulling itself down along the line to meet the rails, and it is removeably attached upon the rails. The manipulator can carry out various work tasks on the subsea installation. A protective frame over the subsea installation will for both solutions shown, prevent a buoy from rising freely up from the rail, and that a manipulator could be lowered down upon the rail.
