BSEE Issues Notice to Lessees On Oil Spill Response Plans The Bureau of Safety and Environ- mental Enforcement (BSEE) in August issued a notice to lessees to the off- shore oil and natural gas industry to clarify the development of oil spill re- sponse plans (OSRP). The notice details the bureau's ap- plication of existing regulations on pre- paring and submitting regional OSRPs, incorporating lessons learned from the 2010 Deepwater Horizon incident. The bureau has approved nearly 80 regional OSRPs since then, using the approach in this notice. This notice supersedes NTL No. 2006-G21 and NTL No. 2009-P03. It does not change existing regulations. In the notice, BSEE encourages ap- plicants to describe the planned re- sponse strategy for each worst-case discharge scenario in the OSRP by considering the following factors: loca- tion of potential discharge, proximity to sensitive resources, estimated dis- charge volume, oil characteristics, ap- propriate source control, containment methods and weathering. The response strategy should also consider the po- tential for use of surface and subsea dispersants, in-situ burning, mechani- cal recovery, wildlife protection, res- cue and rehabilitation strategies, and real-time response capability. BSEE's OSRP review is not limited to assessing whether the calculated effec- tive daily recovery capacity for the list- ed mechanical equipment equals the worst-case discharge volume. A fully developed strategy, according to the notice, includes a list of all recovery equipment and the operating charac- teristics of the systems associated with each skimmer. The plan should show the ability to contain and recover the discharge based on the descriptions of the equipment, functioning together. To view the notice, visit http://1.usa. gov/RMI47M. Buoyant Tower to be Installed Offshore Peru in September The CX-15 buoyant tower, designed by a joint venture between GMC Ltd. (Heathrow, England) and Horton Wi- son Deepwater (Houston, Texas) for BPZ Energy (Houston), has completed fabrication at Wison Offshore & Ma- rine's yard in Nantong, China, and be- gan sailing for Peru in August. The shallow-water buoyant tower will be installed in early September, located about 1 mile from the existing CX-11 platform in a water depth of 53 meters in BPZ Energy's Corvina field in block Z-1. Both platforms will be inter- connected via subsea pipelines. The tower, designed for 12,200 bar- rels of oil per day, is composed of four cylindrical cells and is connected to the seabed by a single foundation can that is integral to the hull structure. The tower and decks with the production equipment will be transported from the fabrication yard to Corvina field on a submersible heavy-lift ship. After up- ending, fixed and variable ballast will be pumped into the hull to provide sta- bility for the platform. A main driver behind the proj- ect was that the transport vessel also performs the main installation as the hull and topside are floated off in se- quence, eliminating the need for a separate heavy-lift vessel at the tower location. n www.sea-technology.com SEPTEMBER 2012 / st 77
