Problems solved by technology

appreciably, this method only works if the camera image is clear and the visual distinction can be identified by the operator
In addition, this method can be subject to human error in visually inspecting the core samples before they are retrieved for analysis, reducing the productivity advantage
The method also cannot determine ore-bearing grade measurement data from this visual analysis

Embodiment Construction

[0031] figure 1 A schematic diagram showing a seabed drilling operation 10 on a seabed 12 below sea level 14 is shown. The seabed drilling operation 10 may be located at various depths below sea level 14, but typically the seabed 12 will be more than 1000 m below sea level 14, and in many cases approximately 2000-3000 m below sea level 14 .

[0032] A seabed drilling operation 10 has seabed drilling equipment 16 connected by an 'umbilical' cable 20 to a surface support vessel or platform 18 . The umbilical 20 provides power, control and telemetry to the seabed drilling equipment 16 . Typically, seabed drilling equipment 16 is powered and operated remotely from a surface support vessel or platform 18 via an umbilical 20 . Although the surface support vessel or platform 18 is shown positioned on the surface of the sea level 14, it will be understood that the surface support vessel or platform may be positioned elsewhere, such as on land.

[0033] The seabed drilling rig 16 h...

Abstract

An apparatus and method for subsea testing of a core sample are provided. The apparatus includes a seafloor drilling rig that drills a borehole and obtains a sample from the seabed, and a sensor mounted on the seafloor drilling rig that analyses a portion of the sample after it is obtained. The sensor preferably includes an x-ray fluorescence sensor, a neutron activation analysis sensor, and / or a magnetic susceptibility sensor, and sends data about the core sample in real time, or at least near real time, to a surface vessel or platform.

Description

technical field [0001] The invention relates to a device and method for seabed testing. In particular, the invention relates to, but is not limited to, the use of sensors, preferably spectroscopic sensors, such as x-ray fluorescence (XRF) and / or neutron activation analysis (NAA) and / or magnetic susceptibility Sensors to test seabed samples, usually core samples, and methods. Background technique [0002] Reference to the background art herein is not an admission that such art constitutes common general knowledge in Australia or elsewhere. [0003] Seabed drilling, especially in relatively deep bodies of water (eg 1000m - 3000m+ below sea level) is a relatively complex, time-consuming and expensive operation. Remote operating systems, usually connected by 'umbilical' lines to a surface support vessel or platform and having seabed drilling equipment, are known for such drilling operations. Seabed drilling rigs typically include a frame that provides support for various comp...
