A telescopic trestle attached to a cantilever beam of a jack-up drilling platform and its application method

Abstract

The invention discloses a telescopic trestle attached to a cantilever beam of a self-elevating drilling platform and an application method thereof. The telescopic trestle is installed on the side wall of the cantilever beam of the self-elevating platform; the telescopic trestle includes a top supporting device, a mechanical transmission device, a trestle Fixed section, movable section of trestle, guide rail, folding guardrail, crawler-type trunking, telescopic inclined ladder, implantation mechanism. The telescopic trestle bridge provided by the present invention realizes the connection between the jack-up drilling platform and the fixed platform by virtue of the characteristics of the cantilever beam of the jack-up drilling platform and its own foldable and telescopic features, improves the working range of the trestle bridge, and saves the platform The installation space has changed the construction form of the traditional trestle bridge and saved the labor cost of trestle construction.

Description

technical field [0001] The invention relates to the technical field of offshore platforms, in particular to a telescopic trestle attached to a cantilever beam of a self-elevating drilling platform. Background technique [0002] Offshore oil and gas development is one of the main contents of today's offshore development projects. Jack-up drilling platforms are the main equipment for offshore oil and gas exploration and development. In offshore operations, the jack-up platform and the fixed platform are sometimes required to cooperate. The jack-up drilling platform communicates oil, gas, water and electricity between the trestle and the fixed platform, and the trestle also acts as a flow channel for the staff. One of the traditional trestle is to use temporary construction, which will take a lot of manpower and time; The deck has a large space, and is limited by the trestle structure and platform space. The length of the trestle cannot be too large, and the jack-up platform a...

AI Technical Summary

Problems solved by technology

One of the traditional trestles is temporarily built, which will consume a lot of manpower and time; the other is to install a fixed trestle with hydraulic or winch as the power source on the main deck of the jack-up drilling platform, but it needs to occupy the main deck of the platform. There is a lot of space on the deck, and limited by the trestle structure and platform space, the length of the trestle cannot be too large, and the self-elevating platform and the fixed platform need to be very close when they are in place
