Fire Fighting Offshore Support Vessel

Oil Drilling and Offshore Support Vessels

As oil drilling becomes depleted on land, more and more of the offshore oil drilling have to be carried out in offshore deeperoil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil waters.

When oil drilling was initially carried out in shallow waters offshore, they used self-elevating units called jack-ups or liftboats. Basically, these were boats with 3-legged attachments which can be towed to the location to be drilled and then the legs were extended into the waters. The floating structure was then jacked up above the water, using a geared rack oil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil and pinion arrangement. When jacked up, the structure looks very much like a 3-legged stool.

As the oil from the shallow waters became depleted, oil drilling companies move further and further to carry out offshore drilling. Column Stabilized Units called semi-submersibles are utilized in deeper offshore oil drilling. These consisted of hollow tank columns that can float on the water, attaching themselves in place by tension legs fixed to the seabed.oil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil

Other offshore units like Floating Production Storage and Offloading (FPSO), SPARS, Tension Leg Platform also become common for offshore oil drilling in deep waters.

To support the offshore oil drilling activity, offshore support vessels are chartered to assist the oil drilling rigs. They will be at the vicinity of the oil rigs, with engines running all the while ready to carry cargo in the form of drilling mud, cement, bentonite, oil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil brine and other chemicals. They are also required to carry pipes, risers, and other spare parts for the rig.

Usually, they will be assisting in tug operations, pulling the floating rigs and sometimes carry workers to and from the offshore oil drilling rigs.

Their size is normally less than 70 meters long, but they have very powerful engines to drive their propellers. Most of these propellers are controllable pitch propeller (cpp), meaning the pitch angles of the propeller blades can be changed hydraulically, so that even though the engine rotates in one direction, the direction of the thrust can be change fromoil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil ahead to astern and vice versa.

In addition, many of them are fire fighting vessels. The engine driven pumps are powerful enough to send jets of water including foam to any vessel or rig on fire. The support vessel itself is protected by suitably spaced fixed water nozzles all around so that there is a water curtain to cool the ship while it fights a fire on another vessel.

The direction of the foam/water monitor where the water shoots out can be controlled remotely from inside the bridge. Usually these ships are equipped with bow and stern oil drilling, offshore drilling, oil rig, jack up drilling unit, column stabilized unit, semi submersible, fpso, fso, spars, tlp, tension leg platform, oil platform, foi, fire, hazard, chemicals, flare, drill, fire fighting, anchor handling, offshore support vessel, osv, cpp, controllable pitch propeller, kort nozzle, tugboat, bollard, foam, floating platform, riser, drilling oil thrusters so that they can move sideways under its own power.

However, since the size of these sophisticated vessels are relatively small, the crew will have to endure quite a lot of sea movement during heavy weather. And the crew sleeping quarters can be quite small.

Offshore oil drilling rigs rely a lot on these small offshore support vessels to bring in their supplies and carry out their activities. Whenever, there are oil drilling activities, you will invariably find offshore support vessels.
