Offshore Rig Firms See End to Historic Downturn

Demand for offshore rig rental globally is starting to recover from its worst ever downturn, led by oil firms' growing demand for harsh-environment exploration and triggering multi-billion dollar tie-ups among drillers hoping to profit, executives said.   While the 2014-2016 oil price crash caused firms to cut exploration budgets, ending a boom in rig demand and bankrupting many owners, energy companies are now seeking to replenish their hydrocarbon reserves.   The nascent demand for harsh-environment rigs, particularly for North Sea drilling, could lead to increased rates for these

the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimeter resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.   Shared Knowledge & Communication In conventional marine construction support terminology, metrology is the work done by surveyors and ROV to acquire various subsea measurements, typically between flanges on separate pieces of subsea infrastructure. These measurements allow precise fabrication of subsea jumpers and spool-pieces.   Traditionally

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

Johan Sverdrup Development Enters Phase 2

The Johan Sverdrup partnership has now decided to proceed with (DG2) Phase 2 of the Johan Sverdrup development, awarding FEED contracts to Aker Solutions, Kværner and Siemens.   Phase 1 of Johan Sverdrup is under development, with first oil scheduled for late 2019.  The partners will now proceed with maturing Phase 2 for the investment decision and submission of the plan for development and operation (PDO) in the second half of 2018. Phase 2 is scheduled to come on stream in 2022. “We must take a generational perspective on the Johan Sverdrup development. Working closely

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
