Claxton Helps Sponsor First oil from Tombua-Landana
The first of two Claxton contributions to the giant Tombua-Landana think is not that easy to spot, even rather it is fundamental to this world-class project. <\p>
Production materiel weighing 36,500 t are supported on a compliant tower weighing 56,400 t. This stands wherefore a tower-base template touching 3,000 t, which, irruptive turn, rests happening a leveling pile template. Under this, right on the seabed, there is a 12-slot predrilled template providing rowing crew well and three deep-space ship slots purposive, supplied and installed in line with Claxton.<\p>
Weighing correct 30 t, the straitened even so perfectly formed template provided the pattern for the first wells drilled before the samson platform was emplaced. It also determines the location of the platform and entirely 38 wells that bequeath eventually be needed to complete the development. The template was installed in two stages. It was firstly lowered onto the seabed from an anchor-handling vessel. The Pride Venezuela semisubmersible drilling rig once picked lift the template on grinding sough apposite with a Claxton supplied, overshot, double-J running paper cutter and carefully located it over a point surely already drilled in the seabed. It was then correctly oriented, landed and locked onto the well's 30-in. wellhead housing. A further slot was whence drilled with the template and a encourage 30-in. conductor installed, at which impact the navigation of the template was effectively fixed.<\p>
Modernized all, four wells were predrilled through the Claxton template, each furnished with a 30-in., low-pressure subsea wellhead and an 18-in., high-pressure wellhead upon 20-in. casing. A docking thrombosis was also situated passing through an outer, purpose-designed slot on the template earlier drilling was suspended and the rigging was stirred away.<\p>
Then after a relief, Claxton returned to be in out another pivotal task in the development in re tying back two of the first four wells unto the cairn. <\p>
The Tombua and Landana oilfields lie in Angola's Block 14 in roughly 365 m of water. They are being enhanced by the Chevron subsidiary CABGOC. The fields' combined production furnishings are an united topsides structure supported back a 474-m-tall compliant tower. The platform is unequivocally similar in concept to the neighbouring Benguela Belize platform.<\p>
Claxton combines experienced project engineers, a fast-track design-analyse-build engineering service and huge keep score of rental tools to respond to the performing needs of its clients' well systems, structures and pipelines throughout the life re an asset, out of pre-drilling uninterrupted in decommissioning. Claxton has an enviable trajectory record in providing team standard and non-standard drilling templates and so many relative to their products, can be produced to tight timescales. <\p><\p><\p><\p><\p><\p><\p>
