Remote Welding Habitat
Statoil ASA had earlier launched a development program to establish technology and a tooling system for diverless tie in and welding of subsea pipelines; the Remote Pipeline Repair System, RPRS.
The RPRS system consists of three main assemblies:
– Remote Welding Habitat (RWH) which acts as the foundation of the system
– The Remote Welding POCO (RWP) which is the carrier of the Remote Welding Tool, the control system for power distribution, welding- and preheat equipment together with support tools and equipment
– The Remote Welding Tool (RWT) – the assembly actually making the weld
The Habitat consists mainly of a base structure, with leg and mud mat assemblies, pipe-claw assemblies and pipe door assemblies. The base structure is designed to be very rigid in order to provide a stable structure during subsea operation. It is also designed for easy and comfortable working conditions offshore.
The project was tailor made to suite Imenco’s primary and core modus operandi, which is to provide a Smart Solution for a Client’s needs. The project was challenging throughout, forging new technological concepts, contributing to new and valuable knowledge for the Imenco team.
