StatoilHydro Responsible for Subsea Job at Marulk
StatoilHydro and Eni Norge signed an agreement under which StatoilHydro will be responsible for the subsea equipment in connection with the planning and development of the Marulk field in the Norwegian Sea. Eni Norge is the operator of the field, where StatoilHydro has a 50% interest. StatoilHydro will under this agreement be responsible for the concept choice, pre-engineering, construction and installation of the subsea production system for Marulk. The Marulk field is planned to be tied in to the Norne vessel, using idle capacity.

Hallin Orders Subsea Vessel
Hallin Marine signed a contract for the construction of an 80m, dynamically positioned (DP2) subsea operations vessel, to be named the Coniston. Coniston will be fitted with an integral saturation diving system, a 50 ton active heave compensated 1500 m depth subsea crane and diesel electric propulsion. The order has been placed with Bina Marine Pte Ltd (Bina Marine) and delivery is scheduled for the fourth quarter of 2010. Hallin will source both the saturation diving system and the crane for installation in the Coniston. The anticipated total cost of the finished vessel will be $51.4m.
First Study of Ocean Acidification
The first comprehensive national study of how carbon dioxide emissions absorbed into the oceans may be altering fisheries, marine mammals, coral reefs, and other natural resources has been commissioned by NOAA and the National Science Foundation. The

need for this national study, to be conducted by the National Academy of Sciences, was outlined by Congress in the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act in 2007. Since the beginning of the industrial era, the oceans have absorbed about a third of all manmade carbon dioxide emissions released into the air. The ability of the oceans to absorb carbon dioxide emissions has reduced some of the harmful effects of heat-trapping greenhouse gases in the atmosphere and on land. But scientists are finding that the continued, increased absorption of these gases is altering the biology and chemistry of oceans in fundamental ways. Absorption of large amounts of carbon dioxide alters the chemistry of the oceans by reducing the pH of seawater. With increasing carbon dioxide in seawater, shellfish and corals cannot absorb enough calcium carbonate to build strong skeletons and shells. The greater acidity slows the growth and even dissolves ocean plant and animal shells.
