Tonga Tsunami Waves Are Still Being Felt in Australia
, where small but measurable tsunami waves were still being recorded as late as Monday afternoon. These may even persist into Tuesday morning.The sea level gauge at Nuku’alofa, Tonga, recorded a tsunami wave of 1.19 meters before it stopped reporting. The waves that subsequently arrived at the Australian coast were comparable to some of the biggest tsunami waves recorded here, including those generated by the southern Chile earthquake in 1960 – one of the largest on record.The Tongan volcanic eruption generated waves of 82cm at the Gold Coast. In southern coastal New South Wales, the tsunami

Crashed US Military Aircraft Found off Australian Coast
An Australian Navy survey ship has located a U.S. military aircraft that crashed off the Australian northeast coast at the weekend and left three Marines missing, Defence Minister Marise Payne said on Monday. The navy divers will conduct remotely operated underwater vehicle operations before considering sending down divers, Payne said in a statement. The U.S. Marine Corps had suspended a search for the three Marines missing since the MV-22 Osprey tilt-rotor aircraft crashed while on regular operations on Saturday. The Marines have described the incident as a "mishap" and

for their 40 year operational life by 40,000 tonnes of chain secured to more than 25,000 tonnes of foundation piles. The Ichthys LNG Project—in essence three mega projects in one—incorporates some of the world’s biggest and most advanced offshore facilities off the Western Australian coast, massive onshore processing facilities in the Northern Territory, and an 890 kilometre pipeline to unite them.

following a battle with the German cruiser Kormoran, which also sank. Since then it was never known why the Australian ship went down so quickly when it was pitted against a relatively small opponent. The final resting place of the HMAS Sydney was only discovered in 2008 off the West Australian coast at a depth of 2,000 meters. Ashtead became involved after being approached by DOF Subsea on behalf of the Western Australia Museum which has been working with Curtin University. The specialist technical equipment supplied by Ashtead allowed researchers to carry out subsea

stages at Shell, will pump up the size equation even more. Competitors include: • Exxon in partnership with BHP Billiton is looking to install what would be the world’s largest FLNG - a 495 meters (1,624 feet) long facility - in its Scarborough gas field off the Australian coast. Design specs call for it to produce an estimated 6 million to 7 million mt/year of LNG from five trains, and to hold 10 storage tanks with a capacity of 380,000 cubic meters. • Malaysia’s PETRONAS plans to launch an FLNG plant in 2015, and has already announced
Fire Onboard Australian Navy Submarine
HMAS Waller, one of the Royal Australian Navy’s submarines, experienced a fire whilst on the surface off the West Australian coast. Emergency response actions were taken to extinguish the fire. There were no causalities. As a precaution four members of the ship’s crew who were involved in the response to the fire have been landed for observation. HMAS Waller had recently completed a scheduled maintenance period and was at sea as part of her return to operations. A full investigation into the incident will be held.

Based on this data, analyses and calculations will be undertaken to monitor fatigue development across crucial structural areas. “The importance of this project, which is set to produce an initial capacity of 8.4 million tons of LNG and 1.6million tons of LPG off the Australian coast per annum, has led to understandably stringent quality and safety requirements,” Paulsen commented. “Our system is one of less than a handful capable of meeting these requirements and, given our track record on LNG FPSOs – we have recently installed systems on ENI’s Goliat

Navy. “Navy is responsible for meeting Australia’s obligations under the UN Convention for Safety Of Life At Sea for provision of national hydrographic services,” Rear Admiral Barrett said. “Our hydrographic ships and aircraft perform this vital task, not only around the Australian coast line, but throughout the region. “The Dawson’s Strait survey is another example of Navy’s highly skilled people working hard to ensure the safe passage of mariners and trade.” Mermaid and Paluma are two of four Paluma Class Survey Motor Launches (SML) operated by the
