Using S- and J-Lay installation techniques, the subsea pipeline is constructed with a single offshore weld, using our insulated field joint sleeve and rapid curing resin. This allows for PIP to be installed as quickly as single-walled pipe.
Our S- and J-Lay systems are fabricated onshore, which allows for full control of the project execution. Our fabrication yard in Normandy, France is suited to double-joint (DJ) PIP production and enables us to deliver quickly and efficiently.
Fabrication can also take place externally if local content production is preferable. This represents an opportunity to train the local workforce and allows for a transfer of expertise. In-country production has been achieved in Nigeria, Angola, Peru, Oman, and elsewhere.
Unlike other systems available on the market, ITP Izoflex provides a more compact system while offering the same thermal performance, which means that more subsea pipe in pipe can be installed with a single reel.
The compressive strength of Izoflex allows for the use of PIP without needing centralizers. This provides enhanced thermal performance, ensures that there are no mechanical point loadings, and results in material CAPEX savings. The lack of spacers facilitates fabrication and reduces construction, installation, and operational risks.
Our reeled subsea flowlines are built at the installation contractor’s spool base in long stalks, in order to reel them onto the installation vessel.
Our insulated subsea systems are all equipped with our micro-porous insulation called Izoflex, which is provided in custom dimensions to be wrapped around the inner pipe. With an as-installed conductivity of 0,007 W/m.K, the performance is at least twice as good as the next best pipeline insulation on the market! What’s more, load-bearing properties allow for continuous insulation, without requiring the use of centralizers.
Thanks to its Interpipe weld, an insulated rigid field-joint sleeve, and our Sleevelox® fast curing resin, our insulated subsea flowlines allow for rapid PIP installation.
Our deep PIP provides an enhanced hang-off capacity for ultradeep water and features improved fatigue characteristics. The technology used is the same as for the standard J-lay PIP, except for the pipe upset ends at joint extremities. Deep PIP provides access to low U-values in ultra-deep water.
