US Coast Guard Cutter Found by ICG

Sixty-seven years after being torpedoed by a German U-boat in January 1942, the final resting place of the Treasury Class US Coast Guard Cutter Alexander Hamilton WPG-34 was finally identified in early September 2009 during an Icelandic Coast Guard operation utilising a Gavia AUV. The Alexander Hamilton became the first US loss in the Atlantic after the Pearl Harbour attacks (7 December 1941) while escorting a convoy to Iceland and within sight of land. Shortly after receiving a new aircraft with specialised pollution detection equipment in July 2009, the Icelandic Coast Guard (ICG) detected traces of oil on the surface... (read more)

Best Practices and Inspiring Bathymetric Lidar Projects

Bathymetric Lidar is a technique to capture geospatial data of coastlines and (shallow) waters. The method has the potential to facilitate the fast and efficient creation of hydrographic data. More and more users are turning to it to support many new and different applications. At Hydro International, we have selected a series of articles on this technique, ranging from case studies that zoom in on some challenging projects using bathymetric Lidar in combination with other survey methodologies, to in-depth articles focusing on the latest trends and developments relating to this hydrographic surveying technology. Acoustically Aided INS and Lidar Aerial mobile mapping using Lidar and GNSS-aided inertial navigation... (read more)

High-resolution Sonar for Engineering

Integrating Multi-beam and Inertial Navigation
In the event of an incident or inclement weather such as a hurricane, an engineer may be required to assess the situation of any subsea structure. Here, the ability to produce quick, accurate and dimensionally correct survey images in an easy to read format is imperative to enable any remedial action such as vessel position, lifting, deployment of ROVs, safe working areas and diving operations. The following ROV project was undertaken at a depth of approximately 80 metres (262 feet) on an artificial reef in the Gulf of Mexico (Eugene Island block 338 oil field) where there are several disused...

Specialised Survey ROV Offshore Testing is Underway

MMT Sweden and Reach Subsea have jointly invested in developing a new, special underwater tool for seabed mapping and pipeline inspection with the Norwegian ROV manufacturer Kystdesign. The potential market for pipeline inspection and survey in the North Sea is 2 billion NOK yearly. This new, remotely operated vehicle (ROV), called Surveyor Interceptor, has the innovative shape, powerful propulsion and advanced instrumentation performs the work 4-8 times faster than existing work-class ROVs. The umbilical and handling system yields up to 6 times better endurance than autonomous underwater vehicles (AUV) The automatic tracking and station holding system delivers unsurpassed stability. Gassco... (read more)

Portable Sonar System for Bomb Disposal Divers

A non-magnetic sonar, equipped with navigation and communication systems, makes it easier for divers to locate submerged objects. In order to assist bomb disposal divers in their operations in coastal and port areas, RTSys (France) has designed a new portable sonar: the SonaDive. It has been developed to detect and locate various types of submerged explosives, whilst enabling the diver to stay at a safe distance. The device can also be used for searches for shipwrecks, bodies and debris. Its use in the civilian sector facilitates the observation of the seabed (aquatic plant habitats, coral reefs, port areas, etc.) for... (read more)

Sub-sea Global Fixing in Deep Water

Currently, the precision of sub-sea global positioning (of UUV and ROV) in deep water is considered to be lagging behind the precision and functionality of GPS-based surface positioning offshore. This is particularly apparent in the operationally favourable combination of high precision and concurrent geographical flexibility. For oil and gas-related offshore construction activities, the technical requirements (including positioning) of seabed documentation are today - in theory - irrespective of water depth, i.e. what is presently required (and achievable) in 300m will also be wanted in 3,000m water depth. But achieving this at 3,000m will still encounter technological, operational and resource related,... (read more)
