Fugro Acquires Metocean
Data Offshore Ghana

Fugro has completed a 33-month period of metocean data acquisition for Hess Ghana Exploration Ltd. Measurements were made at three locations in an area offshore western Ghana known as the Deepwater Tano/Cape Three Points block in water depths of approximately 2,400 m.

A Fugro-manufactured Wavescan buoy was deployed to measure waves, currents and meteorological and seawater parameters, with real-time data displayed on a project-specific webpage. A long mooring was deployed, measuring current profiles over the complete water depth, as well as seawater temperature and salinity. Fugro also deployed a short mooring to acquire near-seabed currents. Data from both current moorings were stored on board the instruments’ internal memories and recovered during each of the service visits, which were at three-month intervals.

Ashtead Supports BP’s
Quad 204 Redevelopment

Ashtead Technology has successfully completed a subsea integrity management project to support BP’s Quad 204 redevelopment of the Schiehallion and Loyal fields, West of Shetland. Ashtead deployed its new Deflection Monitoring System (DMS) to capture critical data required to safely deploy and install two subsea manifolds at 400-m depth.

The system monitors deflection, heading, pitch, roll, depth and other parameters of subsea structures in real time.

BSEE Proposes Rule on
Decom Cost Reporting

This summer, the Bureau of Safety and Environmental Enforcement (BSEE) unveiled a proposed rule that would require entities holding rights-of-way (ROWs) for oil and gas pipelines on the Outer Continental Shelf (OCS) to report the actual costs incurred by those entities during the decommissioning of pipelines.

The objective is to more accurately quantify decommissioning costs associated with OCS oil and gas activities and to ensure that OCS lessees, operators and pipeline ROW holders have adequate financial resources available to cover those decommissioning costs.

The proposed rule would mandate that an ROW holder give this report to the appropriate BSEE Regional Supervisor within 120 days of completion of pipeline decommissioning activities. The Regional Supervisor would be able to request additional information from a pipeline ROW holder to corroborate the information.

Field Testing for SoftShoe
MWD Tool Strings

LORD Corp. has deployed the Generation 3.0 prototypes of the SoftShoe product line for field testing.

They were developed to protect probe-style MWD tool strings from high-energy axial shock. This new generation is designed with a dual compression compliance element, as compared to single compression in previous versions, to provide additional longevity. The improved design ensures that whether a net compressive or a net tensile load is applied, the elastomer section is put into compression.

BOEM Lease Sale 248
Gets 24 Bids

Bureau of Ocean Energy Management (BOEM) Director Abigail Ross Hopper announced that oil and gas Lease Sale 248 garnered $18,067,020 in high bids for 24 tracts covering 138,240 acres in the Western Gulf of Mexico Planning Area. A total of three offshore energy companies participated in 24 bids.

In this sale, BOEM offered 23.8 million acres in federal waters offshore Texas for oil and gas exploration and development.

The sale in New Orleans was the first federal offshore oil and gas auction broadcast live on the Internet to promote greater government efficiency and transparency. A video of the livestream broadcast will be posted at www.boem.gov/Sale-248.

Each bid will go through an extensive 90-day evaluation process to ensure the public receives fair market value before a lease is awarded.

Joint Venture for Seismic
Equipment, Services in Ghana

CGG has signed an agreement with GNPC Operating Services Co. Ltd. (GOSCO), an independent Ghanaian E&P services company, to form a joint-venture company dedicated to conducting high-end 2D, 3D and 4D marine seismic acquisition and related services in the territorial waters of the Republic of Ghana.

The primary aim of the joint-venture company, GOSCO Geoscience Ltd. (GGSL), is to make available world-class seismic vessels and state-of-the-art marine seismic acquisition technologies and services to oil and gas industry players operating in Ghana. The new joint venture will be a Ghanaian indigenous company and be based in Accra.

UXO Removal at German
Offshore Wind Farm

James Fisher (JF) Subsea has completed the location and excavation of unexploded ordnance (UXO) at the north German offshore wind farm Nordergründe in challenging visibility and strong tidal conditions. The result was identification and disposal of shells and grenades discharged during WWI.

Nordergründe is located 16 km off the North Sea coast of Germany.

The UXOs, which had been released by Central Powers and Allied forces during WWI, had delayed planned construction works and were at risk of costing the developer millions.

Of the 224 targets identified, 72 were deemed to be UXOs and had to be detonated with minimal impact to sea life. Two vessels were deployed, with specialist divers used to locate and remove the UXOs during the day and ROVs dispatched to detect and excavate at night.
