A subsea telecommunication system that includes a first acoustic modem that couples to a first vehicle and communicates acoustically. A second acoustic modem couples to a second vehicle and communicates acoustically with the first acoustic modem. A first computer system receives an environmental parameter and updates a physical layer parameter of the subsea telecommunication system in real time in response to the environmental parameter.

Subsea telecommunication system

A method for transmitting signals in a subsea environment includes determining that a quality of an acoustic signal is below a threshold. The acoustic signal travels from a first device, through water in the subsea environment, to a second device. A parameter of the first device, the second device, or both is then adjusted to improve the quality of the acoustic signal when the quality of the acoustic signal is below the threshold.

Subsea oilfield communications system

A technique utilizes spatially resolved temperature measurements to infer the temperature of a subsea infrastructure. According to an embodiment, temperature data, e.g. a temperature map, is determined for the subsea infrastructure and comprises performing remote temperature measurements of water surrounding the subsea infrastructure. Additionally, a metrological scan of the subsea structure may be obtained. Furthermore, a simulation or simulations may be run for an assumed temperature profile along a surface of the subsea infrastructure. The data obtained from the remote temperature measurements, the metrological scan, and the simulation is processed to determine a temperature profile of the subsea infrastructure. This temperature profile can then be used to facilitate a variety of subsea infrastructure management decisions.

Methodology and system for determining temperature of subsea infrastructure

A method, subsea device, and system, of which the method includes acquiring data using one or more sensors of the subsea device, the data representing a subsea environment, compressing the data using one or more processors of the subsea device, transmitting the data wirelessly from the subsea device to the surface device, and decompressing the data using the surface device.

Data compression for communication in subsea oil and gas systems

A method () and an assembly () for milling an obstruction disposed within a wellbore (W) includes a milling module () having a motor () rotating a milling bit (), a first electronics cartridge () for controlling the motor based upon a motor torque value, a tractor module () for engaging with the wellbore and providing a push force against the wellbore to urge the milling assembly in a direction of the milling bit, and a second electronics cartridge () for controlling a push force value of tractor module. The method involves rotating the milling bit () and engaging the tractor module with the wellbore (), and adjusting, iteratively, the operation () based on a calculated torque value and a calculated push force value to maintain the calculated values at around a target torque value and below a push force limit value ().
