Delta SubSea secures MPSV for deepwater GoM operations

Delta SubSea LLC has entered into an agreement with a subsidiary of Hornbeck Offshore Services Inc. for the HOS Bayou, one of Hornbeck’s recently constructed 300 class HOSMAX DP-2 multi-purpose service vessels (MPSVs). 

Deepwater Operations in Galveston to focus on technology and solutions

As the deepwater arena continually evolves, the industry is faced with ensuring safer operations, executing projects effectively, and controlling ever-increasing costs. These challenges will provide ample fodder for discussion at this year’s Deepwater Operations Conference & Exhibition in Galveston, Texas.

TGS to continue GoM deepwater survey

TGS-NOPEC Geophysical Co. (TGS) will continue its Explorer Series seismic acquisition program in the deepwater US Gulf of Mexico. Panfilo 3D will add 11,500 sq km (4,440 sq mi) to TGS' multi-client library in the Lund and Henderson central Gulf of Mexico protraction areas.

PTTEP to take stake in Espirito Santo basin block

PTTEP has agreed to acquire a 20% interest from Shell in the deepwater BM-ES-23 concession in Brazil’s Espirito Santo basin.

Wild Well Control shows new Singapore capping stack

Wild Well Control has unveiled a new subsea capping stack for use in a deepwater well control incident. 

GE to supply subsea manifolds for presalt fields offshore Brazil

Petrobras has awarded GE Oil & Gas a $300-million-plus contract to supply subsea manifold systems for presalt fields offshore Brazil.

Human factors engineering improves accident prevention

In May of this year, Oil & Gas UK published an update to its BOP System Guidelines with the aim of describing good practices for subsea and offshore surface BOP operations on the UK continental shelf.

Helical strake testing suggests path to VIV solution

Vibration in subsea risers caused by vortex shedding is a challenge to operations in deepwater. Proper management of vortex induced vibration requires a balance between acceptable movement and the cost of suppression. To address the questions involved in planning configurations for marine risers, and to investigate the impacts of typical conditions affecting VIV, two programs were conducted consisting of tests along a tubular (just under 100 ft long) that was towed under a rotating arm at high speeds to simulate conditions similar to those a deepwater riser may encounter.

Riser towers deployed for second block 17 deepwater project

In June, Total started production from CLOV, its fourth large-scale deepwater development in block 17 offshore Angola. The basic concept follows the previous three models, with produced oil and gas routed via a network of subsea wells and interlinked flowlines to a spread-moored FPSO. CLOV is the second project after Girassol to connect the risers to the FPSO via hybrid riser towers designed and supplied by Subsea 7, the sole specialist in this technology.

Foamed cement may help ensure wellbore integrity in deepwater

Following the Macondo incident, there was an increased focus on sustained casing pressure in the Gulf of Mexico within the offshore industry. As part of that response, the National Energy Technology Laboratory, the research arm of the US Department of Energy, has engaged in a program to investigate and develop technology to mitigate wellbore integrity issues related to cement failure, especially in deepwater. Research into the characteristics and failure mechanisms of foamed cement has been a primary element of this research program.
