Technip completes 21 subsea jumper metrology operations using Sonardyne International's Lodestar GyroCompatts & saves 8 days working time. Using the latest Wideband Long BaseLine (LBL) acoustic positioning hardware by optimising its technique, Technip was able to complete each metrology operation in an average of 13 hours, with one such operation conducted in only 8 hours. Subsea metrology requires accurate, precise and robust acoustic measurements so that a spool or jumper can be successfully fabricated and installed. For a low-risk, multi-functional and cost-effective solution to the project, Sonardyne recommended Lodestar GyroCompatts, integrating the features of the company’s most advance LBL transponder with a Lodestar Attitude and Heading Reference System (AHRS) in a single ROV-deployable subsea housing. This integration provides high update rate wireless attitude, heading, heave, surge, sway, pressure, sound velocity (SV) and acoustic positioning of any subsea object. Edd Moller, Sonardyne’s Survey Support Group Manager explained, “One of the main challenges of acoustic metrology is to ensure that the measured wideband acoustic range can be translated accurately down from the transponder to the hub level. This is traditionally done using inclinometer Compatts which is then QC’d by rotating the Compatts in the hubs to determine misclosure in both the stab to hub mating and also inclinometer and alignment errors.
The Maritime and Port Authority of Singapore has issued a certificate of approval for the Danelec DM100 VDR for installation on ships under the Singapore registry. The Singapore approval follows on the type approval and European Union Wheelmark certification for the Danelec DM100 issued by the German authority Bundesamt für Seeschiffahrt und Hydrographie (BSH) June 30. The Danelec DM100 is the first and only product so far approved and wheelmarked to meet the revised VDR performance
Seattle-based Crowley Marine Services continues to support the U.S. Navy's Office of the Superintendent of Salvage (SUPSALV) as prime contractor for Phase II of its Ehime Maru recovery project. Phase II, which began in mid-October, involves support of the Navy's Mobile Diving and Salvage Unit One (MDSU) for recovery operations of the Japanese fishing vessel Ehime Maru, which sank in February after a U.S. submarine resurfaced beneath it off the coast of Honolulu.

Ashtead Technology announce at the U.K.'s Ocean Business 2013 expo that it has purchased Sonardyne 6G acoustic positioning equipment value £1.3 million. This latest acquisition is the second significant order placed by the company for 6G in the last 12 months, further strengthening the Ashtead Technology fleet of Compatt 6 transponders, including various sound velocity, digiquartz and inclinometer sensors, GyroCompatts
Danelec Marine today announced the introduction of its third-generation marine Voyage Data Recorder (VDR). The new Danelec DM100 VDR fully complies with the new International Maritime Organization (IMO) VDR standard, which comes into effect July 1, 2014. It also incorporates Danelec’s SoftWare Advanced Protection (SWAP) technology, a new approach to shipboard servicing of marine electronics. “Danelec’s exclusive SWAP solution is nothing short of revolutionary when it
Inventor, Entrepreneur, Industrialist & The Father of Modern Navigational Tech Elmer A. Sperry casts a long shadow over the history of modern naval, nautical and aeronautical technology, one few people know much about, but should, for a man crowned both the “father of modern navigational technology” and “the father of automatic feedback and control systems,” as well as a pioneer of rocket and missile technology.
The new mandatory code for ships fuelled by gases or other low-flashpoint fuels was adopted by IMO's Maritime Safety Committee (MSC), when it met at the Organization's London headquarters for its 95th session from June 3-12, 2015. The Committee also placed unsafe mixed migration by sea on its agenda and considered cyber security matters and passenger ship safety. It adopted new ships’ routing measures and approved a number of circulars arising from items put forward by the subcommittees
