With a range up to 1000 km, a maximum operating depth of 6000 m, and a payload capacity of 0.5 m3, Autosub6000 is one of the world’s most capable ultra-deep water AUVs. The Autosub6000 was developed by the Underwater Systems Laboratory at the National Oceanography Center in Southampton, with funding from the UK Natural Environment Research Council. Autosub6000 is the latest 6000 m rated version of the Autosub AUV series, which has been used extensively for ocean science during the last 10 years, including work under ice operations in the Arctic and Antarctic. The design of the nose and tail sections, including the navigation and control systems, are substantially inherited from the tried and tested Autosub3.

The Remora is specially designed ultra-deepwater ROV. It was designed and built to explore and undertake specialized work at the seabed up to four miles deep. The builder of the Remora 6000, Phoenix International, is an American marine services company experienced in designing and manufacturing unmanned subsea vehicle and also in conducting complex manned and unmanned underwater operations. Phoenix is also a highly regarded operator, when it comes to wet and dry chamber underwater welding, underwater non-destructive testing, manned diving, side-scan sonar operations, underwater tooling, submarine rescue, and engineering design and integration.

The exploratory campaigns by Petrobras and other players continue uncovering new O&G provinces in Brazil.The latest discovery is in the Brazilian northeast region, in the ultra deep Sergipe-Alagoas Basin, where Petrobras identified the presence of hydrocarbons similar to those bearing oil in deep Campos Basin waters. Data analysis confirms the existence of large accumulations in this sector of the Sergipe-Alagoas Basin, implying that there are greater volumes than those found in the shallow water fields such as Guaricema and Dourado. The seismic profile data points to the presence of large volumes of light hydrocarbons. This well, called 1-BRSA-851-SES (1-SES-158)…
