Diamond Offshore Drillship Upgraded by Harris Pye in Brazil
The Harris Pye Group (Barry, Wales) successfully completed on schedule the survey and upgrade of Diamond Offshore Drilling Inc.’s (Houston, Texas) dynamically positioned drillship, the Ocean Clipper, in 90 days, the company announced in February.

The upgrade encompassed accommodation, cranes, steelwork (for which 250 tons of steel were supplied); major pipe renewal in excess of 3,225 meters; and painting. Harris Pye also carried out electrical work, installing a new active heave compensation system, as well as changing out seven transformers, four group starter panels and the complete gas detection system throughout the vessel.

The work was carried out at naval shipyard Arsenal de Marinha do Rio de Janeiro, with more than 600 workers involved. The underwater works were carried out within 40 days while the Ocean Clipper was dry-docked. Once the drillship was back in the water the rest of the work was done alongside. The upgrade took 247,235 man hours; there were no serious accidents or injuries, Harris Pye said. For more information visit www.harrispye.com.


StabFrame Subsea Pile Guiding Frame Deployed Offshore Brazil
The first offshore pile installation operation with the StabFrame, a subsea pile-stabilizing template, has been successfully completed in the OGX Wai­mea field in Brazil’s Campos Basin, joint developers Large Diameter Drilling Ltd. (Cornwall, England) and MENCK GmbH (Kaltenkirchen, Germany) announced in February.

The operation was carried out in association with a contract that was awarded to MENCK by Wellstream International Ltd. (London, England), the main contractor for OGX Petroleo e Gas (Rio de Janeiro, Brazil) on the Waimea development. The contract required MENCK to drive 10 84-inch mooring piles in water depths up to 140 meters, using its MHU 500T hydraulic hammer. The piles were for installing an FPSO mooring system. Steered via a work-class ROV, the StabFrame has a hydraulic release mechanism that allows the pile to be driven further into the seabed before opening the frame. The frame operated under strong currents, estimated to be more than 3.5 knots.

Large Diameter Drilling Ltd. and MENCK are preparing for their next joint pile-driving project of 160 monopile foundations at the Gwynt y Môr wind farm offshore Wales. For more information visit www.lddrill.com.


Expro Establishes Office in China
Expro International Group (Reading, England) opened in early February its operations base in Shekou, China.

The base in the Shekou Industrial Zone will have a workforce made up of operational and support employees that will be responsible for operations in the South China Sea, where the deepwater market is expected to see major growth in the next five years.

The Shekou base has already supported a successful three-well subsea landing string campaign for the CNOOC Yacheng (Shenzhen, China) project, Expro said. The company is also loading out equipment for subsea large-bore electrohydraulic and large-bore slickline equipment for Husky Energy’s (Calgary, Canada) Liwan project in the South China Sea.

The new premises comprise a 700-square-meter indoor workshop, a custom-built pressure test bay and a manufactured clean room. The workshop has two five-ton overhead gantry cranes. The 500-square-meter outdoor yard has a 10-ton overhead gantry crane with access to a 50-ton crane. Matthew Milne will be China operations manager. For more information visit exprogroup.com.


Flexlife Completes First Application of FlexGel
Flexlife (Aberdeen, Scotland) has successfully applied its FlexGel, an oil-based product that is nonsoluble in water designed for halting corrosion of damaged areas of flexible risers or umbilicals within caissons, in a North Sea operation for an oil major, the company announced in February.

The FlexGel deployment was carried out following consultation with the U.K.’s Health and Safety Executive. An annulus breach was discovered during testing by Flexlife in a 4.5-inch gas main flexible riser at a point 4.5-meters subsea. Flexlife deployed 9,500 liters of FlexGel to fill the I-tube from 11.5 meters above seawater levels to 33.5 meters subsea. FlexGel was pumped in approximate meter increments above the mean sea level within the I-tube. This method allowed time for the FlexGel to settle and displace all water and air to fully surround the breach.

“The enclosed area inside a caisson is particularly problematic because there is restricted access for inspection and damage usually occurs around the splash zone level where oxygenated seawater can cause accelerated corrosion,” Stuart Mitchell, Flexlife director of strategic development, said, adding that FlexGel can be deployed topside or subsea without needing rope access or diving teams.

Colleagues Consider Maritime Workers Well-Paid, Survey Says
Oil and gas professionals consider their colleagues to be well-paid, according to results of a survey involving more than 2,000 U.S.-based professionals that was released in February. When asked if industry colleagues were underpaid, each experience group voted “none” as their top answer. The second and third highest-ranked responses were “trades” and “production,” respectively.

Out of twelve industry segments (including “none”), maritime ranked 11th, indicating that respondents think maritime offshore professionals are among the least underpaid. (Votes from professionals within their own specialty were removed.)

In regards to which segment in the maritime offshore industry was underpaid, 52 percent of respondents answered “none.” The next highest-ranked answer was “other” at 17 percent, followed by maintenance engineers and management and support personnel both at 9 percent. Design and construction engineers and trades both received 4 percent.

According to the Bureau of Labor Statistics, average wages in the oil and gas exploration and production sectors ranged from $22,160 to $212,680 in 2010 (the last year from which data are available). Thirty-two roles cracked six-figures, including geoscientists, purchasing managers and health and safety engineers. But, there are 25 roles falling below the national average wage at less than $41,000. For more information visit www.rigzone.com.
