01

Faultless make up

Visual make up reference, pre-installed anti-rotational keys, internal and external self-alignment guides for easy stabbing. Optional sea water exclusion seal.

02

Proprietary hooked thread profile

Thread profile for extra fatigue resistance. High thread taper makes stabbing deeper and easier, the multiple start and low TPI thread design allows final make-up in only 3/4 of a turn.

03

Sealability and structural capacity

Gas tight with metal-to-metal seal, or pre-installed elastomeric seal options. Double shoulder with retainer improves efficiency and performance.

BlueDock®

Functional solution for demanding applications

BlueDock® premium connector incorporates design concepts from the extensively tested Blue® Series, and provides reliable performance in the most complex ultra-deepwater operations requiring gas sealability and fatigue performance. This Tenaris's integrated solution grounds on our experience in pipe manufacturing, premium connection design and welding technology. Pipe and connector are manufactured under the same quality management system, allowing us to supply a full casing and tubing package for offshore wells. Success with major operators is backed by Tenaris's global service network providing technical assistance, product testing, pipe management and technical support in the field.

    Repsol runs TenarisHydril BlueDock® connectors in Trinidad and Tobago

    Repsol has been operating in Trinidad and Tobago since 1995. The Spanish oil and gas company owns vast areas within a mature field with 14 offshore platforms operated in partnership with the National Gas Company of Trinidad and Tobago and Petrotrin. They were the first operators in the country to run the TenarisHydril BlueDock® connectors with elastomeric seal, which provided zero re-make ups and reduced running time.

  • Case Studies

    BlueDock® connectors outstanding performance in deepwater well for Petrobras

    For the 7-RO-155D-RJS well located inside Roncador field, in the ultra-deepwater of the Campos Basin, Brasil, BPetrobras decided to run TenarisHydril BlueDock® connectors, to face the well-known severe deepwater conditions of the region. This Tenaris' integrated solution provided excellent performance with zero re-make-ups nor rejects.

  • CASE STUDIES

    TenarisHydril BlueDock® connectors set new performance benchmark in the North Sea

    A major oil and gas company became started operating of the most technically advanced offshore developments in the North Sea, where many industry “firsts” are being applied to enhance safety and efficiency in drilling operations. In this challenging context, Tenaris supplied TenarisHydril BlueDock® connectors and Rig Direct® services, making the operator achieve a record performance with 34% reduction in running times.
