Bluefin Robotics’ Bluefin-21 is a highly modular AUV able to carry multiple sensors and comprehensive payloads, while at the same time boasting a high-energy capacity that enables extended operations even at the greatest depths. The Bluefin-21 was designed to operate from various ships of opportunity worldwide and has a software package that is flexible, robust, customizable and user-friendly, while also having advanced autonomy and behaviors. Bluefin’s next generation behavior control system provides a highly flexible system for accomplishing the goals specified in a mission plan. This behavior control facilitates dynamic insertion, removal, and modification of mission elements during execution. This is a vital capability in the often uncertain and noisy environments that AUVs face.

Due to the extreme demands placed on subsea equipment used in the pre-salt E&P Petrobras has been forming various partnerships with local and foreign companies to develop specially designed equipment to tackle the hazards of deepwater pre-salt development. One of the newest partnerships implemented by Petrobras, was for a feasibility study on Flexible pipes for practical oil production in pre-salt area with Japan Oil, Gas and Metals National Corporation (JOGMEC). JOGMEC and PETROBRAS have a long history of research and development partnerships which started back in 2005, for collaboration on mutual benefit O&G exploration and production activities, HSE related matters, and R&D activities of the O&G sector.

Flexible risers are being extensively used worldwide for deepwater O&G extraction, offering many advantages over rigid risers. However concerns still exist about the overall safety of the system, especially concerning failures leading to hydrocarbon leaks in the ocean environment.The flexible risers being used in deepwater are designed to work for a period of around 20 to 30 years, which is the expected lifetime of an O&G field. A flexible riser failure could happen due to a number of reasons, such as hostile environmental hazards and material fatigue and if the failure is catastrophic, it could lead to high economic and environmental consequences. Flexible risers comprise multiple layers, and the main layers of concerns are the tensile armor layers which exist to withstand tension loads.

Prysmian announces investmens of around $115 million to start flexible pipe production in its Vila Velha, Espírito Santo industrial plant.Prysmian Cabos e Sistemas do Brasil S. A., announced in november a $115 million investment for 2010, for the expansion of its industrial plant in Espirito Santo in order to produce flexible pipes along with umbilicals already produced at the plant.
