Drill Rig Support
As drilling moves further offshore and into deeper waters, the impact of the oceanographic regime on operators becomes more significant. Recognising the need to support our clients in this regard, MSI offer a range of services specifically tailored for the offshore drilling industry.
Real-time current profiling
Real-time current data through the water column can be of great assistance for a safe and successful drilling programme. Acoustic doppler current profilers (ADCPs) are deployed in purpose-built frames over the side of the drilling platform. Real-time data is then sent from the ADCP via a power / signal cable to a PC running easy to understand customised display software. The choice of ADCP depends on the water depth and can range up to 1000m using a single instrument. In addition, a combination of units can be used where the water depth exceeds 1000m with data from deployed ADCPs being telemetered to the rig in real-time using acoustic modems.
Real-time wave measurements
As with current measurements, real-time wave measurements can provide invaluable information during drilling operations. These are normally provided either by installing a wave measurement buoy in the proximity of the platform and telemetering the data via radio to a receiving station installed on the platform, or by installing a wave radar on the drilling platform.
Data displayed includes parameters such as significant wave height, wave period & wave direction.
Real-time weather measurements
|The installation of an automatic weather station on a rig can assist in safely carrying out deck operations, as well as provide input into a decision making system for safety determined operations such as crew changes via helicopter or vessel. The data can be displayed in real-time providing parameters such as wind speed, wind direction, air temperature, air pressure, relative humidity, cloud height and visibility, and logged on the hard drive for future processing.|
Accurate site-specific weather forecasts are essential in support of offshore operations. MSI, through our association with Aerospace & Marine International, provides custom forecasts accessible 24 hours / day via a secure web server, e-mail, and / or fax, in text and graphical formats for easy dissemination and application, featuring:
As well as site specific forecasts in support of drilling operations, MSI can provide an optimum voyage routing service in support of rig tows. This service includes:-
To support the issued forecasts, additional images can be provided as required. Examples of these are given below (move your cursor over the image for a description or click the image for a full size version).
