Efficient and Cost-Effective Solutions for Jacket Tank Designs

Jacket Tank Design for Food and Beverage Industries

Jacketed tanks keep materials warm or cool by circulating heating and cooling fluids around the tank. They are used for various applications, including chocolate, liquid food blending and aging, ingredient mixing, and batch sterilization.

Conventional jackets come in a wide range of sizes and pressure ratings. They can be fitted with baffles and zones to improve thermal control. However, these components increase weight and cost.

Dual-walled jackets

Conventional jackets can be zoned and baffled to deliver uniform temperature regulation, but these extra components add weight and increase costs. Also, as the surface fabric clings to sweat vapor, it slows its movement to the outside and causes a clammy feeling in your skin.

A dimple jacket design, on the other hand, uses a large area of equal-spaced depressions to create a heat exchange mechanism. Cold water or hot steam passes in and around the depressions to keep tank contents cool or warm, respectively. This can save a process step, reducing production cost.

Most of the jackets in this guide are filled with down, which is warmer than synthetic insulation. However, down loses its warmth when wet. Fortunately, many companies make hybrid designs that combine down with synthetic fill for optimal warmth and durability. These include Patagonia’s Storm10 and Rab’s Torrentshell.

Internal coils

Many food and beverage industries rely on jacketed tanks to heat or cool materials. These tanks can be used for milk and fruit juice heating or cooling, ingredient blending, ice cream production, and more. These tanks are usually fitted with internals, which can improve the heat transfer efficiency. They can also reduce the amount of energy needed to operate a tank.

Depending on the design, internals may include baffles that alter flow patterns and increase turbulence. They can also be equipped with agitating nozzles, which can help with heat transfer in the liquid inside. In addition, a variety of internals are available for different temperature ranges.

These types of jackets can be either immersed in the liquid or fastened to the outside of a tank, called limpet coils. In the latter case, throttling the utility makeup flow instead of the jacket or coil flow can prevent fouling and maintain a constant fluid velocity across the heat exchange surface.

Double-wall jackets

A double-wall tank is a safer option for storing corrosive or polluting chemicals such as chemical fertilizers, fuels, nitric acid, ferric acid, and hydrochloric acid. It’s also an excellent choice for a storage tank that will be subject to continuous operation or transport. The second skin prevents leaks and retains any liquids that might escape from the first jacket in the event of an accident.

The outer jacket is made from dimple plate and the inner space is filled with a special heat transfer fluid, Bucomastic, to improve its thermal performance. This system is particularly suitable for retrofitting existing tanks.

This jacket is a top pick for warmth, comfort and weather protection. Its waterproof construction keeps you dry and the insulated fill helps keep your body warm all day. It features the latest iteration of Columbia’s Omni-Heat Infinity gold dot technology that uses a reflective surface to retain your body’s heat and eliminate cold spots. Its double-layered construction also blocks wind to keep you warmer.

Conventional jackets

Conventional jackets provide a full perimeter of heating or cooling around a vessel. They are a good choice for smaller, lower pressuretemperature applications. COMPRESS makes it fast and easy to design conventional jackets using the rules of Division 2. The higher allowable stresses in this section allow for thinner inner shell walls, which improves heat transfer.

Plate Coil Jackets

Plate coil reactor jackets are fabricated from whole pipes, which are strapped to the vessel. This type of jacket offers superior strength, up to 750 psi. They can be used for liquid heat transfer and high-temperature industrial processing. Plate coil jackets are a bit more expensive than other jacket types, but the increased strength can save money in the long run on vessel replacement costs. They also require good bonding to prevent insulating gaps between the plate coil and the vessel. A major drawback of plate coil jackets is their susceptibility to fatigue failure due to rapid thermal cycling.

Warmest Winter Jackets for Extreme Cold

Which Jacket is Warmest in Winter?

A jacket’s insulation determines its ability to retain body heat. A high CLO rating (the measure of an item’s thermal resistance shared by LifeLabs) is a good indicator but length and other features also matter.

One of our writers from chilly Michigan says this jacket has the right mix of warmth and versatility to handle everything from cross-country skiing to daily commutes on public transit. It’s also water-resistant to prevent soaking from rain and snow.

The North Face McMurdo

The North Face McMurdo is one of the warmest insulated winter jackets in the world. This parka uses a thick and cozy 850-fill power down that is treated with water resistance, keeping you toasty dry in snow or rain. This is a great winter jacket for outdoor enthusiasts who want to keep warm while doing their favorite activities.

While fill power is a good indicator of warmth, other factors like extra-long jackets and hoods are also important. The North Face McMurdo is a fantastic example of this – it features a roomy hood that blocks out extreme elements and even has removable faux fur along the chin.

The North Face McMurdo is ideal for those who will be using their jacket for general winter use. While it doesn’t have the waterproof protection of some other options on this list, its lightweight and comfortable design makes it perfect for walking around town in freezing weather. This jacket is also a fantastic choice for those who aren’t going to be doing intense activities in sub-zero temperatures.

Canada Goose Expedition Parka

The Canada Goose Expedition Parka is one of the warmest jackets available on the market. Originally developed for scientists in Antarctica, it can withstand temperatures as low as -22 degrees Fahrenheit. The bombproof shell and 625-fill duck down are designed to withstand extreme cold weather and wind chill. The insulated tunnel hood and real coyote fur trim are also added for extra warmth. Other features include recessed rib knit cuffs, storm flaps, snaps, and velcro to ensure that you are fully protected against the harsh elements.

Despite its amazing qualities, the Expedition parka isn’t ideal for all activities. It’s bulky and uncomfortable to sit down in for long periods of time. It’s also not suitable for strenuous activity, as exerting yourself can make you feel overheated. However, for those who face arctic conditions on a daily basis, the Expedition parka is well worth the investment. For anyone who doesn’t, the price may be a little too steep.

The North Face Aconcagua Women’s Jacket

Named after the highest mountain in the Western Hemisphere, this jacket was made to be a warm winter companion for any adventure. It is insulated with natural and recycled synthetic insulation to conserve body heat, whatever the conditions.

One of our writers who lives in a cold climate wears this jacket daily, calling it “really warm” without feeling too heavy. She says the thigh-length fit and recessed elastic cuffs keep the chill off her arms, and the stand-up collar offers extra warmth for her head.

The North Face describes this coat as an “active layer,” which means it is built to be comfortable for hiking and other strenuous outdoor activities. It is also great for walking or commuting on public transit, as stylist and lifestyle director Donnell Baldwin has found. The fabric’s DWR finish keeps precipitation at bay, and the 550-fill goose down in the body provides plenty of warmth. The sleeves and shoulders use a hybrid fill of Heatseeker insulation for wind and water protection.

Arc’teryx Therme

If you’re going to be in frigid conditions for extended periods of time, you want a jacket that’s ready for it. Arc’teryx offers a range of hard shell jackets with weather-resistant properties like wind and water protection, as well as insulated jackets that provide warmth without the bulk.

The Therme is a long parka that’s designed for comfort and protection from the elements. It uses a GORE-TEX membrane and breathable laminate that keeps rain, snow and wind at bay. It also has a Coreloft insulated hood that provides additional insulation.

While the Therme doesn’t have as many pockets as some of the other jackets on this list, it does offer a number of useful features. The hood is ample, and the jacket has a no-lift gusset that allows for more movement. It also has a waist cinch that helps you keep the cold out. The hand pockets are large, and the jacket is made from a durable fabric that’s easy to clean.

Structural and Geotechnical Analysis for Jacket Platform Design

Jacket Platform Design

Jacket structures are the base for fixed offshore platforms used to extract hydrocarbons from seas and oceans. A jacket consists of a self-supporting skeletal tower comprising leg members and bracing. The structure is secured to the sea floor by piles extending through guide sleeves.

Different corrosion zones affect the jacket module differently. For accurate assessment, a proper method should be employed to determine the base shear capacity.

Structural Analysis

Structural analysis is an important part of the design process. It involves modeling the structure and analyzing forces to determine stresses, buckling, and displacements. This is done using structural software. The analysis can be performed either linearly or nonlinearly. In the latter, nonlinear dynamics and fluid-structure interaction are incorporated, and plasticity and kinematic strain hardening effects are taken into account.

A sensitivity study is also conducted to evaluate the effects of different parameters on the structural performance. This helps in identifying the critical parameters and limiting the design scope. Finally, a life cycle cost (LCC) analysis is done to estimate the expected cost of the platform over its lifespan.

The structural analysis also considers the actions of the jacket structure during its transportation from the fabrication yard to the installation site and during sea transportation, mating, installation, and hook-up. The design should be capable of surviving these accidental loads as well as the environmental and functional loads.

Geotechnical Analysis

The geotechnical analysis involves the evaluation of soil conditions at the proposed location of the structure. This is usually accomplished by drilling and sampling a core of soil. The data obtained are used to determine the soil resistance developed on the jacket leg extensions and lowest level of horizontal bracing.

In addition to linear static analysis, a nonlinear dynamic analysis is normally carried out. This includes fluid-structure interaction, large displacements, plasticity and kinematic strain hardening effects. It also considers pile-to-jacket leg annulus interaction.

Moreover, a modal analysis is also done to capture the natural frequencies of the structure. Lastly, time history dynamic analysis is performed to increase the accuracy of the results. This involves considering the axial force and flexural anchor forces of the jacket elements as random variables over a critical direction. The damage index is then determined based on the performance function of tension and compression. The results are then used to perform a structural check.

Design of Pile Foundations

When a jacket platform is constructed, the geotechnical engineer explores soil conditions at the location of the foundation by drilling and sampling. This information is used to provide a basis for the structural design of the foundation elements.

The design of pile foundations is important in jacket platforms because they transfer the loads of the structure to the underlying soil or rock layers. These are usually weaker than the structure above, so it is necessary to have strong support underneath. There are several types of pile foundations that can be used, including end-bearing piles and friction piles.

Energy piles are designed to be driven into a soil layer with a high bearing capacity, such as the transition layer between a hard and soft stratum. Their shape is typically a long shaft with a rough surface to increase frictional resistance. Driven piles are installed by striking them repeatedly with a hammer, while bored and cast-in-place piles are created by drilling and pouring concrete while gradually withdrawing the drill tool.

Design of Jacket Legs

After fabrication of jackets, they are loaded onto barges or a heavy lift ship and transported to site. They can then be skidded or lifted upright into saddles for the final positioning of the legs on the seabed. Bracing members are then welded to the legs and scaffolding is used for access to the top interfaces.

During installation, a berthing dolphin can be made integral with the jacket to minimize the amount of piling on site. This can also help with buoyancy control of the jacket during its launch sequence as it reduces the required ballast load. A rubber diaphragm closure is usually incorporated in the jacket leg to prevent water entering the annulus between the pile and the jacket leg during jacket flooding operations.

Three-legged jackets have the advantage that they have fewer piles to drive into the seabed, so noise and environmental impact is minimised. However, they are not as stable as four-legged jackets and could collapse if one of the legs fails. Therefore, they require more extensive structural analysis than four-legged jackets.
