Title: Alan Murray Clark: Innovator in Subsea Wellhead Technology

Introduction

Alan Murray Clark is a notable inventor based in Aberdeen, GB. He has made significant contributions to subsea wellhead technology, holding a total of 3 patents. His work focuses on enhancing communication and monitoring capabilities in subsea environments.

Latest Patents

One of his latest patents is a wellhead assembly designed for communicating with the casing hanger annulus. This subsea wellhead assembly allows for communication from the outer surface of an outer wellhead housing to a casing annulus. The design includes seals between the outer and inner wellhead housings that define an annular chamber when the inner wellhead housing lands. The outer wellhead housing features a communication port formed through one of its sidewalls, while the inner wellhead housing has a passageway extending from the annular chamber to the bore of the inner wellhead housing. This innovative design ensures that the casing annulus, located radially inward of the inner wellhead housing, is in communication with the outer surface of the outer wellhead housing through the passageway, the annular chamber between the seals, and the communication port.

Another significant patent is the ported subsea wellhead, which includes communication passages that enable monitoring of annulus pressure surrounding inner and intermediate strings of casings at the surface. The passages have outlets that allow communication to the tree assembly for monitoring. In one embodiment, the passage outlets are located in the bore of the high-pressure wellhead housing and communicate with the tree assembly along an isolation sleeve. In another embodiment, the outlets are located on the exterior of the high-pressure wellhead housing and communicate through a flying lead coming down from the tree. This design enhances the monitoring capabilities of subsea operations.
