AUV Tracking System Tested in Loch Ness

A collaborative research project called Autonomous Surface and Sub-surface Survey System (ASSSS) aims to deliver an integrated system to provide a means of conducting low cost, shore based, full water column marine surveys using multiple unmanned systems. The project, part funded by Innovate UK, hopes to encourage wider adoption of unmanned systems.The project is being led by a U.K. based developer of unmanned and autonomous marine systems, ASV Global. It combines the advantages of autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs) to further data gathering opportunities.

Maersk Drilling: First Order for "Chela" Crane

Maersk Drilling awarded GustoMSC the first order for the uniquely designed crane Chela, which is to be installed on Maersk Invincible (GustoMSC CJ70 design) which is currently operating on Valhall for AkerBP. Chela is desgined to improve safe handling underneath the cantilever and reduce total time spent on wells.     Chela offers an extra hand in operations as, due to its crablike motion characteristics, it can reach below the cantilever as well as elevate towards the main deck, providing crane access to an area traditionally blocked by the cantilever when drilling. “We are

Finding Monsters on the Ocean Surface

The study of extreme wave events in the ocean has become a popular area of research in recent years. Aside from seafarers, extreme waves impact coastal communities and are of great interest to marine renewable energy companies. This is particularly prevalent in the face of coastal erosion, rising sea levels and uncertainty in how the wave climate will change in a warming world. However, much of the current research is based on modeling and experiments. Extreme wave events – including storm waves, rogue waves, storm surges and tsunamis – are rare, and as such are difficult to observe and

Airborne drones have become widely available over the past few years, have increasing reliability and have lowered in price. However, for wave elevation measurements under strong, gusty wind conditions in a harsh marine environment their applicability and reliability is limited. Moreover, commercial deployment of flying drones requires expensive certification and training. This led us to develop the C-DRONE: an autonomous/remote operated vehicle which can be deployed and retrieved using a rope and hook to measure

Subsea Infrastructure: Challenges & Solutions

As offshore oil and gas reserves become ever more difficult and costly to recover, the demand for innovative technology has never been greater. Joe Orrell, managing director at RED Engineering, considers some of the challenges in subsea infrastructure design and the role of fast track engineering solutions.   The offshore oil and gas industry, even in times of low prices and abundant supply, is driven by the almost relentless search for new fields to replace those coming towards the end of their natural productive lives. Often this forces exploration in ever more challenging environments and

Trump Offshore Oil Proposal Could Unlock 65 Bln BOE

The Trump administration's proposal to open up almost all of U.S. offshore waters to oil and gas drilling could unlock up to 65 billion barrels of oil equivalent (boe), attracting billions of dollars in investment, consultancy Rystad Energy said.   Last week, U.S. Interior Secretary Ryan Zinke said a draft program would make over 90 percent of the outer continental shelf's total acreage available for leasing to drillers, a national record.   "Looking purely at areas that are potentially going to come out of restriction, we are talking about something closer to 65 billion boe,"
