Deepwater Solutions

Premium Connections



Today, oil and gas operators work at depths of over 10,000 feet (3,000 meters) and in total vertical depths of more than 40,000 feet (12,000 meters). Working in these conditions poses several challenges, including strong ocean currents and high pressures downhole. To be able to reach oil and gas reservoirs deep within the ocean bed, deepwater wells must go through several miles of thick sand, dense salt and hard rock. The increased formation pressures and rising temperatures are a threat to well integrity. With regards to production for different SURF configurations and fluid characteristics material requirements for line pipe, coating and welding used in these environments are increasing.

Testing protocols and regulations for deepwater operations, including API RP 96, have become increasingly more stringent, including scenarios of survival loads. Well designs must be adjusted to comply with these demands and safely meet the challenges posed by subsurface geology and drilling hazards. In these environments, product reliability and performance are a must.

Committed to sustainable offshore development, oil and gas companies constantly seek solutions that can reduce the operational footprint and minimize the release of contaminants into the ocean.


Tenaris offers a comprehensive range of products and services that promote reliability, efficiency and safety in even the most challenging environments.

Our TenarisHydril premium connections ensure superior performance in deepwater environments, offering features such as extra compression resistance, maximum sealability and superior fatigue resistance. The TenarisHydril Wedge 623™ connection was specifically developed to comply with changes in deepwater operating requirements in the Gulf of Mexico. It was the first connection designed according to API RP 96 and is API 5C5 CAL-IV compliant.

The TenarisHydril Blue® Series provides high reliability and versatility to perform in even the most complicated environments. Based on the field proven and one of a kind Blue® technology, our Blue® Quick Seal connection was designed for large OD surface casing, while Blue® Max and Blue® Heavy wall connections –both API 5C5 CAL-IV compliant- offer excellent performance when requiring heavy and extra heavy wall pipe.

Our Dopeless® technology enhances premium connections’ performance and reliability, while providing operational, well productivity and HSE benefits. This dry, multifunctional coating is applied in a fully automatic process at Tenaris mills, guaranteeing that the exact amount of lubricant is applied.

Tenaris offshore line pipe products are designed and manufactured to the highest industry standards. They can be used in a wide variety of applications and customized to meet the requirements of each specific project even in extreme heavy wall sizes and combined with state-of-the-art anticorrosive and insulation coatings. The threaded and coupled Blue® Riser connection provides an outstanding level of fatigue resistance and sealability performance in deepwater top tensioned riser applications..

Our TenarisHydril BlueDock™ weld-on connectors for large diameter casing are specially built for complicated environments. These products feature easy stabbing and trouble-free make-up, providing reliable running along with 100% ratings in tension, compression and bending.


Tenaris Premium Connections

Premium Connections

The complete range of high performance TenarisHydril premium connections offers outstanding compression and sealability along with collapse resistance, thereby promoting reliability and efficiency in deepwater operations.


Dopeless® technology

Our dope-free coating reduces running times up to 25%, improves the reliability of the installation, produces a 10% savings of the total pipe cost in offshore operations and improves HSE standards.



We have developed proprietary casing and tubing steel grades that are able to withstand the high pressures and temperatures found in deepwater operations.


Offshore Line Pipe

Tenaris offshore line pipe yields exceptional performance in a variety of applications in both deep and ultra-deepwater operations. These products meet DNV OS F101, ISO 3183, API 5L, EN 10208 and ASTM standards.



Tenaris provides pipes with different coating solutions in compliance with the most rigorous international standards for both onshore and offshore oil and gas projects. Tenaris coating and line pipe packages can be used in ultra-deep waters and other demanding applications.
