Offshore Rig Basics

Fuel Drill water This approach turned out to be a very cost-effective way to drill from small fixed platforms. The semi hull offers superior station keeping and vessel motions compared with ship or barge-shaped hulls: The columns offer a reduced area to excite the hull The work platform or main deck is above all wave action TADs are seeing new use on deepwater production platforms, such as spars, tension leg platforms TLPs , and deepwater fixed platforms, which operate beyond jackup water depths. Converted in from a semi MODU. Growth of offshore drilling units Things were off and running in the s, with numerous operators getting into the rig ownership and operation business and new drilling contractors being formed every year. In the early s, Shell Oil saw the need to have a more motion-free floating drilling platform in the deeper, stormier waters of the GOM. Shell noticed that submersibles like the Mr. Charlie, now numbering almost 30 units, were very motion free afloat compared with monohulls. The idea was to put anchors on a submersible, use some of the California technology for subsea equipment, and convert a submersible to what is now known as a semisubmersible or semi.

So dad steps up on the front deck and readies himself.

Separate multiple email addresses with semi-colon Your Email: Send email to me as well Subject: The modules for this platform are now being constructed at several yards, and will be carried to the Valhall field during summer of with a subsequent hook-up and commissioning phase. The scope for Aker Solutions also includes commissioning assistance. Aker Solutions estimates the contract value to be approximately NOK million. The old quarter and production platforms QP and PCP on the Valhall field will be gradually phased out due to subsidence.


It is one of the appendices in “Supply Ship Operations” but items can be added at the request of our readers. Typically a while ago some-one asked me what an “AB” was, so it is now the first item in the section. In the British nautical hierarchy after some time at sea a seaman can take an examination for EDH Efficient Deck Hand and then after further years at sea can be formally qualified as an AB.

Single cable capsules do not go on ships, they are specifically designed for, and used by, offshore rigs and platforms. Twin-fall lifeboats are designed for ships and seaman and adapted for offshore use. Primary Focus on the Offshore Worker SSI has designed its capsules understanding that the user of the system will be an offshore worker and not a seamen.

At the center of the capsules design is the knowledge that the user of the system is not a seaman, and may have very limited understanding of boats and the sea. Twin-fall lifeboats, which are primarily designed for ships and then adapted for rig and platform use, do not start with the same fundamental understanding of their user. Their primary user is a seaman.

Keppel FloaTEC LLC, a wholly-owned subsidiary of Keppel Offshore & Marine Ltd (Keppel O&M) has secured a contract worth about US$40 million from PTSC Mechanical & Construction (PTSC M&C) to provide engineering, technology and construction management support services for the Repsol Ca Rong Do Tension Leg Wellhead Platform (TLWP) to be built in Vietnam.

All platform systems had been tested and commissioned prior to the April 10th sail away from the Zykh yard in Baku, where the platform and associated seabed foundations were built and assembled. The platform was then towed to an intermediate location some 70 km from Baku, where the platform legs were successfully mated to the three foundation cans, which are each 30 meters in diameter and 15 meters in height and weigh tons.

The TPG platform was then towed to its final location in m of water, where the legs were lowered and then cemented in place. The final installation of the platform over the pre-drill well template required critical precision. Safety is one of the highest priorities in operation activities being performed at the Sangachal Terminal.

This is the first time that this innovative technology is being used in the Caspian Sea. This unique installation method was successfully completed offshore on April 27th. The platform’s offshore hook up and commissioning activities have already begun, and the project remains on target to achieve First Gas from Shah Deniz during the fourth quarter of The TPG is a unique achievement for the Caspian.

The entire platform, including the legs, was assembled at the Zykh construction yard near Baku. The three legs for the platform and their foundation structures were built entirely in the Zykh 3 area of the yard, and the whole platform was assembled at the quayside of Zykh 4. Only two other platforms of this type have ever been built, both of which are operating in the UK North Sea.

The TPG platform is a large jack-up comprising drilling, production and accommodation for personnel with a total weight of 32, tons topsides 22, tons, legs and foundations 10, tons. The platform’s drilling facilities are capable of drilling wells with a length of over 7 km and with an outreach of more than 3 km, while its production facilities are capable of processing approximately 1 billion cubic feet

The company will work closely with subcontractor Kvaerner on joining together the platform’s seven modules, which will be transported to Norway in the second quarter of The scope also covers planning, management and prefabrication. The contract value is approximately NOK million and will be split about equally between Aker Solutions and Kvaerner. Aker Solutions’ share will be booked in its first-quarter orders. The work starts in February and will initially involve about people from Aker Solutions, Kvaerner and Statoil, rising to as many as 1, people at its peak next year.

It will be carried out mainly in Stavanger and offshore. Kvaerner will work closely with Aker Solutions and contribute to all parts of the project delivery. The agreement also contains hook-up options for the field’s processing and living quarter platforms, which are scheduled to be installed in ENDS Aker Solutions is a global provider of products, systems and services to the oil and gas industry. Its engineering, design and technology bring discoveries into production and maximize recovery.

The company employs approximately 14, people in about 20 countries. This press release may include forward-looking information or statements and is subject to our disclaimer, see http:


After the permanent platform has been installed, the necessary drilling equipment including a large drilling derrick is positioned on the platform for drilling a number of wells one at a time. After one well is drilled, the drilling derrick is skidded to a new position and a second or third well is drilled. After the selected number of wells have been drilled from the platform, the drilling equipment including the derrick is removed and placed on barges and towed to another location or to shore.

Production equipment is then installed on the platform and the wells are produced after connecting the platform to shore by means of a pipeline. From time to time it may become desirable to drill an additional well or two from the same permanent platform. However, the drilling equipment and derrick must be reinstalled on the platform to drill these additional wells.

The Shah Deniz field is located in the Azerbaijan sector of the Caspian Sea, approximately km south of Baku and 90 km east-south east of Sangachal in water depths ranging from 50m to m.
