Subsea tie-back integrated deliveries

Reusing existing infrastructure by developing small & marginal tie-backs reduces the CO2 footprint and improves the energy efficiency of subsea oil & gas production. We provide integrated solutions using key in-house technologies: flexible pipe, diverless tie-in, and subsea pipeline structures.

With an outstanding track record of subsea deliveries, we develop cost-effective and installation-friendly solutions giving our clients superior flexibility at the installation stage of their projects.

Benefits

Reduced interfaces and client teams
Optimized delivery schedule
Improved logistics and mobilization with terminations delivered on reel
Combined offshore support crew for flexibles and tie-ins

Key benefits of NOV diverless tie-in with termination integrated in flexible pipe end-fitting

Reduction of size and weight	Termination and porch have compact design, which gives a reduction in size and weight of the subsea structure and the reel packed flexible pipe.
Reduction of hub loads	Termination is located around the End-fitting, which reduces overall length and weight of the assembly.
Reduction of testing	Termination design eliminates traditional flange to flange connection, hence the testing of it
No need for flexible handling head	Termination is designed with trunnions for handling with slings during the installation
Savings on time during the subsea tie-in operation	Termination design allows end-fitting to swivel, which removes restriction on torsion during the handling and making tie-in operation fast and efficient.
One less leak path	No flange to flange connection between end-fitting and termination
