Standards in Offshore Survey

The offshore industry has a range of standards in common use. As survey contractors/subcontractors, how far should we aim for standardisation in the work we do and how much scope should we leave for differentiation between ourselves? In common with most industries, the offshore survey industry has its fair share of standards that are defined by clients, standards bodies, trade associations and legislative bodies, to name but a few. These can relate to data exchange, work practice, quality management systems or health and safety matters. Good standards can be beneficial; they may improve safety and quality of work, reduce unnecessary... (read more)

Offshore AIS Network Complete

Norcontrol IT has supplied Petroleos Mexicanos Exploration (PEMEX) with a large offshore AIS network. Whilst AIS is generally considered a tool for port and coastal applications, the offshore industry can benefit from the extra data it offers. The project is located in the Bay of Campeche in the Gulf of Mexico and spans some 150 platforms throughout the entire area. Norcontrol IT has installed eight AIS base stations supplied by Kongsberg Seatex, a subsidiary of Kongsberg maritime. PEMEX is currently in the process of installing AIS transponders on supply vessels and other ships serving the oil production facilities in the... (read more)

Digital Video Offshore

A Review of Current and Future Technologies
The advent of digital video introduces a new era for the offshore oil & gas industry. Digital methods of data acquisition have permeated most offshore survey techniques. The Offshore Survey and Remote Systems and ROV divisions of the International Marine Contractors Association (IMCA) have published a review of the field in Digital Video Offshore: A Review of Current and Future Technologies, for offshore contractors and their clients. The adoption of digital encoding and recording of video data has gathered pace over recent years and many annual inspection campaigns now include digital video deliverables. This step has been dictated either by... (read more)

Deepwater Offshore Wind Turbine

The Engineering Business (EB) has celebrated the succesfull installation of the second deepwater offshore wind turbine. EB's BOWTIS - Beatrice Offshore Windfarm Turbine Installation System - was used by Talisman Energy (UK) Limited in the Moray Firth in Scotland. The REpower 5MW turbine was installed in a single lift from a floating barge, and forms the second half of the Beatrice Wind Farm Demonstrator Project.   The first REpower 5MW turbine, also installed using BOWTIS last year, was fully commissioned on 8 May.   EB began campaigning for the concept of installing offshore wind turbines in a single lift in...

Surveying for Offshore Wind

Developing the Third Market
Many giants are drilling for oil and gas: the gold of the sea. Since the beginning of the new millennium, however, a new kind of energy potential of the sea has been discovered: wind energy. The fastest way to create substantial amounts of this green energy is to build offshore wind farms. The seas have space enough, the wind yield is higher than on shore and the visual impact, which is so often a difficult hurdle to overcome on shore, is not an issue at sea. Wind energy is characterised by renewability and sustainability, both of which are important issues, as we... (read more)

Offshore Survey Equipment Order

Chinese oil company CNOOC has placed an order with A.P. van den Berg for the delivery of a WISON-APB seafloor survey system. COSL, subsidiary of this company, will use this sytem on one of their geotechnical drill vessel in the South-Chinese sea.   This is the second Chinese order in a short while, after the delivery of a land survey vehicle. A.P. van den Berg exports the majority of its products world-wide. Oil companies are surveying existing oil and gas fields very intensively as the demand for fossil fuels is huge. They also are searching for new fields in deeper... (read more)

Offshore Survey Award

The organisers of Offshore Survey 2007 Conference, held in Southampton in March 2007, have announced the award for best presentation. Delegates were asked to vote for the winner, having received conference proceedings on CD. He is David Whitcombe of Shell, whose paper focused on improving recruitment, training and retention of personnel in the offshore survey industry.   As a result of the presentation, a working group has now been formed by representatives across the industry to address this issue. The prize - a brass and leather bound telescope - was awarded on the basis of votes cast by the delegates at... (read more)

Deep Offshore Metrology Tool

Spool and jumper metrologies constitute a critical path in the subsea pipe installation process. They can often occupy large construction vessels ‘just’ for survey operations that may last more than a full day, requiring several types of sensors (long baseline, gyros, depth sensors, etc.), as well as highly qualified surveyors. Moreover, measurement error may lead to spool misfit that has a dramatic impact on the overall project schedule. A newly designed metrology system, which may be seen as an acoustic taut wire, has now reached maturity and has been extensively used in 2006/2007 for different spool and jumper metrology projects,...

HTMV Solutions for Offshore

One of the great challenges for cables in offshore applications is the combination of high temperatures, harsh environments and high voltages. The demands put on the materials are intense and the need for longevity in offshore doesn't make it any easier. Habia Cables’ new HTMV (High Temperature - Medium Voltage) range enables smarter and more economical solutions in different applications, such as heating cables and power cables for pipelines, pumps and ROVs. Habia Cables use fluoropolymers to attain higher temperature and chemical resistance than traditional XLPE-based insulation systems. Some of the development challenges included three layer bonding of the materials... (read more)
