    [1] Many of the kayakers were freshly trained that day, in rented boats. [1] When the Polar Pioneer arrived in Elliott Bay, it was met by a flotilla of hundreds more protesters in kayaks and other small boats, voicing their opposition to oil drilling in Arctic waters because of the risk of oil spills, undersea oil well blowouts, damage to ...

  3. Taisun - Wikipedia

    en.wikipedia.org/wiki/Taisun

    Taisun was built to install very large (up to 20,000 tons) integrated modules on top of a vessel's hull. Traditionally, offshore vessels such as drilling semi submersibles or FPSOs were built from the ground up in modules of 1000 to 2000 tons, which meant that much installation, hook up and commissioning work was left to be done on board where access is limited and efficiency is decreased.

    Mud pump (#4) is a reciprocal type of pump used to circulate drilling fluid through the system. Mud tank (#1) is often called mud pits and stores drilling fluid until it is required down the wellbore. Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame ...

    The first offshore mobile drilling platform was the Hayward-Barnsdall Breton Rig 20, first operated in 1949. [2] This rig had evolved from the inland drilling barges which were used to drill in marshes and protected waters in up to 10 feet of water. The Breton Rig 20 was 160 feet by 85 feet, and could work in 20 feet water depth.

    Deepsea Delta semi-submersible drilling rig in the North Sea Comparison of deepwater semi-submersible (left) and drillship (right). A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes.

  7. Platform supply vessel - Wikipedia

    en.wikipedia.org/wiki/Platform_supply_vessel

    A primary function of a platform supply vessel is to transport supplies to the oil platform and return other cargoes to shore. Cargo tanks for drilling mud, pulverized cement, diesel fuel, potable and non-potable water, and chemicals used in the drilling process comprise the bulk of the cargo spaces. Fuel, water, and chemicals are almost always ...

  8. Drillship - Wikipedia

    en.wikipedia.org/wiki/Drillship

    A drillship is a merchant vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. In recent years the vessels have been used in deepwater and ultra-deepwater applications, equipped with the latest and most advanced dynamic positioning systems.

  9. Rotary steerable system - Wikipedia

    en.wikipedia.org/wiki/Rotary_steerable_system

    The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit”. Push-the-bit tools use pads on the outside of the tool which press against the well bore thereby causing the bit to press on the opposite side causing a direction change.
