Embodiment Construction

[0024] Such as Figure 2-Figure 5 As shown, the mooring positioning of the mooring operation ship is realized by the working anchor. In order to keep the local anchor cable in a suspended state and not contact with the seabed facilities, so as to avoid damage to the original facilities on the construction site, the present invention adopts the following steps:

[0025] Step 1: When the mooring operation ship arrives at the offshore construction site, before the anchor cable 1 enters the water, determine the position according to the relative distance between the on-site operation ship and the submarine facility, and install the anchor cable 1 at the set position in advance. Several clips 2, present embodiment is: four clips 2 are installed, and clip 2 adopts wire rope clip, steel structure, can be directly clipped on the anchor cable after tightening. The setting position is: after the anchor cable 1 is launched into the water, the four clips 2 installed between the cloth are ...

Abstract

The invention relates to an operation method of an anchoring type operating vessel when crossing over a submarine facility during anchoring. The method adopts the following operation steps: step one, distributing and installing a plurality of clamps at intervals in the set positions for the anchor ropes in advance when the anchoring type operating vessel reaches an offshore construction operation field and before the anchor ropes are positioned into water; step two, installing a plurality of floating camel structures in the set positions for the anchor ropes through the respective connecting retaining rings; step three, after completing the installation of the floating camel structures in the set positions for the anchor ropes, positioning the anchor ropes into water. The operation method has the advantages that the operation is simple, the maintenance is convenient, the anchor ropes positioned above the submarine facility can be in the suspension state and not in contact with the submarine facility while the construction cost is reduced, thereby avoiding the damage from the anchor ropes to facilities such as submarine oil pipelines and submarine cables around the prior offshore production platform, so that the submarine facility can be protected safely and effectively; simultaneously, the safety factor of underwater operation and the overall construction safety are improved.

Description

technical field [0001] The invention relates to an operation method for an anchored operation ship when anchored, in particular to an operation method for an anchored operation ship to cross a seabed facility when anchored, and belongs to the field of offshore oil engineering. Background technique [0002] In offshore oil development projects, various platforms such as oil production platforms, living platforms, and central processing platforms need to be built offshore. In order to cooperate with the offshore oil production platform for oil production operations, many auxiliary facilities such as submarine cables and submarine oil pipelines are laid around the offshore oil production platform. Therefore, there are many facilities and complex terrain environment around each offshore oil production platform. [0003] In the secondary development of oil and gas fields, engineering construction needs to be carried out near the original offshore old platform. In order to prote...
