Double On-site Seal Repair on Offshore Platform in Mexico

In August a team of Hydrex divers traveled to Veracruz, Mexico for a stern tube seal repair. The operation consisted of the underwater replacement of the damaged seals on both assemblies of a semi-submersible offshore platform.   The unit left the field after its project was finished and was berthed alongside to have repair and maintenance work carried out without docking. We were asked to perform the stern tube seal repairs during the available window of opportunity.   After the diving team performed a thorough underwater inspection of the assembly they installed on of our flexible

The Quest to Find and Explore USS Indianapolis

. In the early hours of July 30, 1945, having just completed a secret mission to deliver materials from California for the first operational atomic bomb, “Little Boy” to a naval base on the Pacific island Tinian, Indianapolis was en route from Guam to Leyte when it was torpedoed by Japanese submarine I-58.   Indianapolis sank quickly – reportedly in just 12 minutes – leaving little time for the crew to deploy lifeboats or for an emergency signal to be sent. It is estimated that 800 of the nearly 1,200 Sailors and Marines on board survived the sinking, but a communication error

Multinational Task for Australian Mine Warfare Team

 Fifty navy divers and mine warfare specialists from Australia, New Zealand, the United States, and Britain converged on Bland Bay, New Zealand for Exercise FULCRUM recently.   The contingent had to locate and dispose of 16 dummy mines of varying shape, size and weight, set throughout the bay.   Australian and British autonomous underwater vehicle teams used remote environmental monitoring units to scan the bay floor and identify mine-like objects.   The US and New Zealand then sent out divers to confirm whether or not they were mines, said Lieutenant Teina Hullena of the

Uncharted Depths: Exploring the Marianas with SuBastian

ocean.    With some areas reaching depths more than 36,000 feet, scientists rely on a range of pioneering deep-sea technologies to survey the unexplored regions of the Mariana Trench. In 1987, the submersible Alvin was the first to visit the nearby Mariana Back-arc, a zone of highly active submarine volcanism and hydrothermal vents hidden 13,000 feet below the ocean’s surface. After returning to the Back-arc 30 years later equipped with the Schmidt Ocean Institute’s new underwater vehicle SuBastian, scientists can now fill gaps in our understanding about the biogeography of these

Manned Sub to Survey Titanic Wreckage

A new mission will send the first manned submersible to the Titanic wreck since 2005.   The mission will see a survey expedition team use the latest subsea imaging technology and a newly built manned submersible to assess the condition of the shipwreck and document artifacts in the debris field. The OceanGate Expeditions exploration team will conduct annual surveys of the wreck in collaboration with experts from the Advanced Imaging and Visualization Laboratory AIVL at the Woods Hole Oceanographic Institution as part of an ongoing long-term study to document the current condition of the Titanic

Consolidation – A Path to Subsea Vessel Sustainability

 In recent years, the speed with which newbuild vessels have entered the market has amplified the subsea vessel demand/supply imbalance, says a report by Douglas-Westwood London.   This has been further exacerbated by sustained low oil prices, as operators defer the sanctioning of new offshore projects which could have supported vessel utilisation.    As a result, the average vessel dayrates declined by an average of 35% between 2014 and 2016. The weak market conditions have meant that many low specification vessels have struggled to hold on to existing charter rates, whilst
