Deep-water Research Centre

Schlumberger has signed a joint cooperation agreement with the Universidade Federal do Rio de Janeiro (UFRJ) to build an international research centre on the university's campus. The agreement marks the first research and geosciences center to be located at UFRJ Technology Park. The partners will focus on research and development activities in the deep-water pre-salt environment.     The emphasis will be placed on the development of geosciences software for the exploration and production sector; new technologies to meet reservoir challenges in pre-salt environments; and the creation of a geophysical processing and interpretation Center of Excellence covering time-lapse seismic and...

Deep-water Coral Reefs

Acoustic recognition and geological setting
Cold water coral reefs, notably the stone coral Lophelia pertusa, have been found extensively in deep Arctic waters such as the Norwegian Sea. The use of multibeam echosounding, together with advanced visualisation and analysis tools, has been a key to many spectacular discoveries. The world's largest cold water coral reef - the Røst Reef - was mapped in detail in October 2002. Located in the dramatic setting of a large submarine slide, this provides an excellent example of how catastrophic geological processes can create special marine habitats. Another major reef complex - the Sula Reef - demonstrates how mounds select... (read more)

GEBCO and Deep Water

Data Assembler, Converter, Interpreter and Disseminator
GEBCO uses deepwater survey data to produce bathymetry maps and grids. Published maps appear complete but are in fact based on very little data. Only a portion of the deep data that could potentially be put to use is contributed to the public domain. All would benefit were more data submitted to data centres. BackgroundWhile the general public thinks that all the seafloor has been mapped and many hydrographers and ocean scientists accept published maps and datasets as faithful representations of the deep-sea floor, in reality only a small percentage of the seafloor has ever been directly measured; estimates range...

Deep-water Black-box Retrieval

A Game of Hunt-the-pinger Against the Clock
Restricted operating life, limited range and bearing ambiguity in deep water are the known limitations of current locator beacons mounted on aircraft. These problems raise important questions: what is the best method of locating existing pingers and what can replace them? In deep water, pinger detection equipment could be installed on a submarine. Alternatively, a transponder beacon can provide both range and bearing information, as well as demonstrate a significantly longer listening life. Although heavier and therefore not suitable for light aircraft, commercial aircraft could easily accommodate such beacons allowing easier retrieval of the aircraft black boxes. In the July/August...

Hydraulic Vibrocorer for Very Deep Water Use

OSIL (UK) has added a vibrocorer to its existing product range due to customer demand. The hydraulic system can be used as a stand-alone sediment corer or can be easily adapted to allow integration with subsea vehicles. The use of hydraulics opens the system up for use in very deep water in conjunction with a seabed hydraulic power pack. A range of systems are available depending on the specific application, offering from 2,500kg to over 7,000kg centrifugal force and each providing a well-structured core sample that retains the individual layers. The hydraulic model is based around the existing modular electrical vibrocorer,... (read more)

Multibeam Echosounder for Medium to Deep Water

The RESON SeaBat 7160 multibeam echosounder has been developed for marine exploration, seafloor habitat mapping and hydrographic charting in medium to deep water (3 to 3,000m). Equipped with X-Range, it provides improved system immunity to external noise. The system can operate in water depths of between 3 to 3,000 metres, offering up to 512 high-density equidistant beams with a selection of coverage modes including features such as variable and steerable swath, together with real-time pitch and roll stabilisation maximising useable swath and performance. The SeaBat 7160 also provides the collection of high-density water-column data all wrapped up in a processing... (read more)

100th Deep-Water Multibeam Order

Kongsberg Maritime has received its 100th order for a deep-water multi-beam echosounder system, to be delivered in November 2009 to the U.S. Naval Oceanographic Office (NAVOCEANO). The contract, for delivery of an EM 122 (1° x 1°) is part of the multi-beam sonar system upgrade program for the U.S. Navy T-AGS 60 class survey vessels.   Kongsberg Maritime's first deep-water system, the EM 12, which was first delivered in 1990, was based on the design experience gained with the successful initial model, the EM 100 (95kHz). In 1993 a special 12kHz version was delivered based on a US tender for... (read more)

Oceaneering International Orders Six Deep-water DVLs

Rowe Technologies (USA) has received an order for six SeaPilot DVLs from Oceaneering International (USA). Rowe Technologies has also developed a 4,500-metre rated titanium SeaPilot DVL for deep-water deployments. The SeaPilot DVL provides a slightly smaller footprint when compared to other products in the market and also provides the industry's newest electronics platform. A leak detection sensor is integrated into the SeaPilot DVL .The leak sensor will provide ROV pilots with real time information on the status of the structural integrity of the DVL and will allow pilots the opportunity to shut down the DVL if the structural integrity is...

Deep-water Measurement Campaign Completed Offshore Portugal

A deep-water measurement campaign offshore Portugal has been completed by Metocean Services International (MSI), having achieved 100% data return across multiple mooring locations. MSI was contracted by Calecore, on behalf of Repsol, to profile currents at two separate locations in over 750m water depth. This project marks the first time the company has worked in Portuguese waters. The moorings consisted of multiple ADCPs and Aquadopp current meters, spaced across the full depth of the water column, in order to provide a high-resolution image of the complex current interactions at each location. Deployment took place from Calecore’s multi-role vessel Kommandor Calum... (read more)
