Two-phase separation/pumping to make subsea debut on Marimba
At the top of the VASPS unit are the fluid pressure housing and the helix. After a number of turns, gas is opened to the gas annulus and flows into the separator. The liquid then flows through the liquid discharge tubing by means of an electric submersible pump. [20,191 bytes] Schematic of the VASPS subsea hardware. [15,476 bytes]

Who needs appraisal wells?
For BP's Eugene Hughes, designing for minimum appraisal was another crucial consideration in deepest West Africa. "Like anyone else, we're trying to go to fast-track developments. These days if you want money from the BP board, you have to get your oil out quicker. If you ask them for four years, they'll give you three. We used to think five years was good."

Deepwater template employs central guide post for seabed installation
In February the doors of the KOS Training Center in Bergen opened for the first time. Here the company will train new employees, in classes of 14 at a time, in the skills of the subsea service engineer. The course comprises 12 weeks of concentrated learning, theoretical and practical, accompanied by exams. The trainee engineers are then attached to one of KOS's offshore crews to gain on-the-job experience.

SUBSEA TECHNOLOGY Parted Marlim pipeline recovered from 2,700 ft depths off Brazil
A diverless ROV-based system recovers a pated pipeline off Brazil in three steps. The Stena Apache supported the recovery of a pipeline from 2,700-ft water depths. During the completion of a deepwater pipeline in 2,000-3,000 ft water depths off Brazil last year, a pipe joint weld failed, sending the pipeline to the seabed in 2,700 ft water depths. Stena Offshore of Aberdeen recovered the 12-in. pipeline using its ROV-based recovery system shortly afterward and continued laying the line.
