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

Abstract

The invention discloses a telescopic trestle attached to a cantilever beam of a self-elevating drilling platform and an application method. The telescopic trestle is installed on the side wall of the cantilever beam of the self-elevating drilling platform. The telescopic trestle comprises a jacking device, a mechanical transmission device, a trestle fixed section, a trestle movable section, a guide rail, a folding guardrail, a crawler-type wire groove, a telescopic inclined ladder and an implantation mechanism. According to the telescopic trestle provided by the invention, by virtue of the characteristics of the cantilever beam of the self-elevating drilling platform and the folding and telescopic characteristics of the self-elevating drilling platform, the connection of the self-elevating drilling platform and the fixed platform is realized, the working range of the trestle is enlarged, the platform mounting space is saved, and the construction form of a traditional trestle is changed; and the labor cost for building the trestle is saved.

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 ocean development projects, and the jack-up drilling platform is the main equipment for offshore oil and gas exploration and development. Offshore operations sometimes require cooperation between the jack-up platform and the fixed platform. The jack-up drilling platform communicates oil, gas, water, and electricity with the fixed platform through the trestle, and the trestle is also used as a flow channel for staff. 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 d...
