Kongsberg’s Sonar Supports Five Deeps Expedition

Kongsberg Underwater Technology’s newest multibeam echo sounder, the EM 124, installed aboard the DSSV Pressure Drop, played a key role in the solo human submersible dive in the Atlantic led by the Five Deeps Expedition team. 

Victor Vescovo, in his private submersible, reached the bottom of the Puerto Rico Trench, a depth of 8,376 meters. The EM 124 was specifically used to precisely map the ocean floor to determine the deepest point in the trench prior to the dive.

The EM 124 is the fifth generation of a range of new multibeam systems from Kongsberg Maritime and is the successor of the EM 122, the de-facto standard in deep water multibeam systems.

It is a modular multibeam echosounder that performs high resolution seabed mapping from shallow waters to full ocean depths (11,000 m) with unparalleled swath coverage and resolution.

“The EM 124 is already a proven success, with this very first delivery producing fantastic results,” said Chris Hancock, vice president of sales for Kongsberg Underwater Technology. “The Five Deeps Expedition leaders and the crew of the DSSV Pressure Drop were excellent to collaborate with throughout the installation and commissioning phase of this project. Our expert technical team was able to optimize system performance and conclude successful sea acceptance trials just prior to the scheduled dive in the Puerto Rico Trench. Over the next 12 months, we will continue to work together and support the expedition remotely through our Mapping Cloud service.”

The EM 124 is arguably the most advanced underwater sonar currently installed on a civilian vessel,” said a Five Deeps Expedition representative“It produced digital 3D renderings of the sea floor that were used to identify and verify the deepest point in the trench that ultimately determined the dive location. This was crucial to the success of the mission.”

The Five Deeps Expedition is the first manned expedition in a commercially-certified submersible seeking to reach the deepest points in the five oceans by the end of 2019. The journey will cover 40,000 nautical miles (74,000 km) and the submersible will have descended through at least 72,000 m (236,220 ft.) of water.

6th Offshore Well Intervention Conference Gulf of Mexico

The Offshore Well Intervention Gulf of Mexico conference (OWI GOM) is returning to Houston, Texas for its sixth year on Wednesday 20 – Thursday 21 November.

Featuring Anadarko, BP, Shell, Chevron, BHGE and Oceaneering, the conference aims to help operators transition to the latest compliance updates, WI systems and business models that enhance safety, quicken well access and improve commerciality.

Across two days, more than 200 delegates, 15 exhibitors and 30 speakers will network together and create solutions to some of the most pertinent industry challenges right now, through a conference programme focused on:

  1. Clarifying compliance updates
  2. Quicker well access and safer well control
  3. ​Understanding HPHT well intervention (systems)
  4. Forecasting well intervention activity, discussing new commercial models and comparing platform options
  5. Best practice riserless well intervention
  6. ​The latest well intervention equipment

For registration, speaking or sponsorship enquiries contact Abigail Clifton on aclifton@offsnet.com; +44 (0) 203 793 8800.
