Importance of Getting Lay Up Labuan

Lay Up Labuan

Lately, we have actually been reading and listening to reports from mobile offshore drilling gear proprietors that a variety of Lay Up Labuan are going to be stacked– sadly, this is a cycle that we have been with before. From previous experience, we have found out that disabling rigs with proper dehumidification devices mounted aids to maintain the stability of the below deck devices and also the quarters. When it comes time for the rig to be reactivated, it relies on the appropriate faster and in far better problem than a rig that is chilly stacked at dockside or in the middle of a bay.
Iron starts to dramatically wear away (corrosion) at 60% RH as well as over (Garverick, Rust in the Petrochemical Sector). According to the American Bureau of Delivery, for the very best results in preserving listed below deck equipment and equipment areas, they suggest “full dehumidification at 35% to 45% RH … to avoid sweating or humidity deterioration damages”. Holding a family member moisture of 40% to 75% will certainly maintain the honesty of seals as well as gaskets. Provided all these aspects, we normally suggest around 45% RH for rig layups.

Desiccant Wheel DH Units
Cooling Agent DH Units
Desiccant Wheel DH Units are used by the US Naval Reserve Fleet and are the “gold standard” for lay-ups due to the fact that they are not detrimentally affected by reduced ambient air temperatures like Refrigerant DH Units.

The Desiccant Wheel DH Device utilizes a revolving, regenerative, open fluted matrix wheel that is impregnated with a hygroscopic, non-toxic element. A humidistat checks the loved one moisture in the room as well as turns the DH Device on or off to attain and also preserve the desired moisture collection point. The humidistat can be built into some DH Units at the return air inlet, which is where the air is mosting likely to be one of the most moist.

Dry air is much heavier than humid air, so the completely dry air will displace the humid air and also press the damp air back to the DH System, which is installed in the dehumidified area. Dry air will also look for areas where there is even more humid air. So hard-to-reach areas, crawl spaces, tanks, and spaces that are permitted to be usual to the area being dehumidified will certainly likewise be dried out and also correctly protected.

Usually, we advise one dehumidifier for all the listed below deck equipment rooms and one dehumidifier for the quarters– the exact same technique applies to both spaces. Dehumidifying the machinery areas listed below deck is apparent. However, it is additionally a good concept to dehumidify the living quarters if the gear is not mosting likely to be occupied throughout Lay Up Labuan Evaporating the quarters avoids mold and mildew and also mold from expanding in the enclosed quarters– all the bedding remains nice as well as completely dry as well as the above ducting and framework does not corrosion.

There are likewise a number of semi-submersibles with DH Units in the caissons and pontoons, which ought to be used for conservation of these locations in the event of a lay-up.

To determine the appropriate size of the dehumidifier, we would certainly compute the gross volume of the location to be dried out and after that number that the DH Device will certainly turn that gross volume over every 4 to 6 hrs on a stacked rig. This typically ends up being a little DH Device such as a 600 CFM or 1200 CFM size unit.

With a Desiccant Wheel DH System, we prolong flex air duct that deals with the dry supply air to the farthest point away from the DH place. After that, the return air circulates back to the DH Device through all the open doors. The resurgence air consumption and exhaust requires to be ducted from outside the dehumidified area to stop ambient, moist air leakages. Low cost, insulated adaptable duct can be made use of.

You can also use extremely little DH Units (60 CFM) to dehumidify isolated areas such as crane cabs and also drillers/dog houses. Typically tiny Cooling agent DH Units are made use of in these locations and just a drainpipe line requires to be run beyond the area.
Lay Up Labuan

Generally, rig hands as well as rig electrical contractors are more than efficient in setting up a dehumidification system on a rig Lay Up Labuan, which gets rid of the costly demand to hire an outdoors service provider for this job

No person likes to consider rig Lay Up Labuan. That is not what this energy market is everything about. We desire full throttle onward. Not turn around. Not quit. However a rig that is correctly preserved as well as evaporated will survive being temporarily inactive as well as will have the ability to go back to operation faster than one that is not.

Should the demand occur to stack a gear, contact Eldridge and we will aid you with dehumidifier application, sizing, as well as flex duct/fitting transmitting design as a value added solution.
