Total, Chevron Team up in Gulf of Mexico Oil Exploration

 Total announced that its subsidiary, TOTAL E&P USA, INC., has entered into an agreement to capture seven prospects operated by CHEVRON U.S.A. INC. in the deepwater Gulf of Mexico. The agreement covers 16 blocks.   The associated prospects are located in two promising plays and areas of the GoM: Wilcox in Central GoM next to the Anchor discovery, and Norphlet in Eastern GoM nearby to the Appomattox discovery. Total’s participation in these wells will be between 25 percentand 40 percent.The first of these wells was spudded late July on the Ballymore prospect in Mississippi Canyon.

Ichthys Explorer Moored off Western Australia

The world’s largest semi-submersible platform, the Ichthys Explorer, has been safely moored in the Ichthys Field, 220 kilometers off the north coast of Western Australia, where it will be located for 40 years, as part of the INPEX-operated Ichthys LNG Project.   Bardex Corporation supplied four moveable Chain Jacks and 28 underwater Barlatches to support the handling of 28 mooring lines. The mooring operation was completed ahead of schedule with the assistance of Bardex lifecycle services. Bardex said the use of its Clump Weight contributed to the efficient mooring up operation.

Marine Hazards to Subsea Cables and Pipelines

In February 1989 the RoRo vessel Vinca Gorthon ran into heavy weather and sank off the Dutch coast. She landed on an oil pipeline that was severely damaged. Although the probability of sinking on top of a pipeline is very small, the incident showed that it can happen.   Shipping traffic can represent a potential hazard to subsea pipelines in various ways, such as sinking or grounding, lost containers or an anchor hooking onto a pipeline. Over the years MARIN has contributed to the development of a method by which the burial depth of a cable or pipeline is determined on the basis of actual

How the right measurement technology can help Chile’s aquaculture industry fulfill its potential   Climate change is just one of the challenges that ports in Chile increasingly have to deal with, and an investment in the latest Doppler technology and online systems has proven to be a significant benefit for its ports. How can Chile’s aquaculture industry maximize this technology’s potential?    From the early 1990s to 2007, Chile’s aquaculture took off, and by 2006 it was producing 38 percent of the world’s salmon. Now, the country produces 1.4-1.

A new buoy from Danish company Resen Waves harnesses wave energy to provide continuous power and real time data connectivity to autonomous instruments and machinery in the oceans as a plug and play solution.   While instruments and machinery in the sea have traditionally been powered by batteries, PV or diesel generators, this typically requires regular ship operation to replace batteries or supply of fuel and maintain diesel generators. This is not always possible due to weather and can become costly, meaning power is often economized by cutting back on data transmission, which limits the

Buoy Designed to Monitor Turbidity at Dredging Sites

Transmitting turbidity data every half hour, blinking at dusk and being anchored with a 100 kg weight: a buoy intended for long-term turbidity measurements has seen the light of day.   Dredging is a common and economically viable solution for the removal and subsequent treatment of contaminated sediment. Turbidity is thus an ideal surrogate for simple assessment of general water quality and effects of sediment disturbance.    MacArtney’s German subsidiary, MBT GmbH, has manufactured a turbidity monitoring buoy, which is intended for deployment for accompanying environmental

designed for ocean depths of 1300 meters. “We fully depend on good suppliers and Subsea 7 has done a great job in this year’s campaign,” says Per Rusås, project director for Aasta Hansteen.   He praises the SURF team for properly planning and completing this year’s marine season and avoiding any serious incidents. “It takes knowledge, experience and hard work to reduce risk in operations like these. The result is a perfect illustration of how to conduct an offshore installation campaign, and demonstrates Statoil’s ability to carry out complex deep-water
