... Objectives/Scope The project was a 2km, electrically heat-traced, subsea pipe-in-pipe (PIP) system for transportation of a bitumen-like material across a shipping channel. Due to the viscosity of the bitumen, it must be transported at a minimum of 160°C; has a normal pipeline operating...

... with an operating pressure of 300barg and 150°C operating in a maximum water depth of 2000m as a case study. The PIP system is considered to be laid by a reel-lay method, which is amenable to inducing the residual curvature at the pre-determined RC locations during pipelay process. The study includes the special...

... The High Pressure and High Temperature (HP–HT) subsea field developments are increasingly using Pipe-In-Pipe (PIP) systems for transportation of production fluids due to superior thermal conductivity performance compared to wet insulated single pipe system. PIP systems can provide...

... Abstract In typical insulated Pipe-in-pipe (PIP) systems, both extremities of the outer jacket pipe are swaged down close to the inner pipe and are welded directly to the outer surface of the inner pipe. This full penetration weld (hereafter called swaged weld) works as a structure connection...

.... The produced gas is transported using a 20 km long pipe-in-pipe (PIP) system to the Cidade de Vitoria floating, production, storage and offloading system (FPSO) located in the Golfinho field to be processed and then exported onshore through an existing gas pipeline. Technip was awarded an engineering...

The highly insulated PIP system was installed in a snaked configuration to achieve significant CAPEX reduction over the very few...

... provide the required steady state outlet temperatures for many long flowline systems at a fraction of the cost of equivalent PIP systems. In addition, due to their heat effected zone, the cool-down rates for B&C systems are far greater relative to PIP systems. This paper presents some of the new found...

... to a high degree by Arctic Engineers and Constructors. SYSTEM DESCRIPTION The PIPS system consists of a tank, located near the bow of the ship which is closed at the top but has large openings to the sea near the bottom. A compressor or blower forces air into the top of the tank to expel water through...
