Introduction

Florescence marine is a long history manufacturer of marine bollards and cleats worldwide.Our range of bollards and cleatsis unsurpassed by any other manufacturer or supplier. Maritime can provide many of the most popular“legacy" style bollards, optimized bollards, or cast any new style to meet custom requirements. lt is Maritime's mission to provide thebollards or cleats our customers require, and not just what we offer.

Florescence marine began designing and manufacturing mooring bollards almost 30 years ago with the philosophy tosupply the highest quality products backed by relible engineering and testing.Numerous suppliers of marine bollards inthe market consider only the commercial aspects of the product.Florescence's ability to consider technical and commercialconsiderations collectively is what has made our company unique.Our customers rely on mooring bollards and cleats toperform as expected, and it is our experience, technical expertise, and integrity which provides this assurance. .

BOLLARD TYPE & SELECTION

Mooring bollards are available in a wide range of shapes, load ratings,and materials, of whichno single combination can satisfy all customers. Accordingly, Florescence provides a wide rangeof products.The most commonly used style of bollards are the Single Bitt, Double Bitt,T-head,Staghorn, and Kidney, as well as simple cleats used for smaller vessels.The particular type of bollarda customer requests, as well as the material used to cast the bollard, is usually a function of whathas historically been used at the operator's facility. These differences can also be geographicallydependent. For example, T-head bollards are more prominent in some regions while Single Bittbollards are more commonly used in others. It may also be the preference of the consultant asthey may have considered a particular bollard model, along with its particular shape, load rating.and anchorage, during the detailed design of the berth.This choice must be respected to ensurethe safe usage of the product. While customer preference may determine the model supplied by Florescence, there are differencesamongst models that should be considered when selecting a bollard.T-head and Staghorn bollardscan handle higher line load angles than Single Bitt and Kidney shaped bollards.This feature maybe of particular importance where very large changes in water level result in significant differencesin line angles.Large differences in line angles may also occur at multipurpose berths where widelyvarying vessel sizes frequent the same berth. Double Bitt bollards are useful when high densities of mooring lines are present.The two columndesign allows two lines to be secured and independently released without having to compromisethe mooring of an adjacent vessel.The opposing sloping columns are particularly useful for securingof spring lines as their greatest strength is parallel to the berth. Kidney shaped bollards offer an economical solution for installations where securing of mooringlines at high angles is not a concern.This style is not recommended when multiple mooring lines will share one bollard as there may be a possibilityof an unintentional release due to the shallow lip at the top of the bollard.

MATERIALS

Mooring bollards are typically manufactured using the sand casting method with the materials of choice being either steelor ductile iron.Other types of cast iron can be used, but they lack the predictable ductile failure mode preferred by Engineers. The choice of whether to use cast steel or cast iron is usually a preference of the customer, often decided by whatis currently being used at the facility.Again, geographical preferences exist when making this choice.Some valid technicalcharacteristics that may influence the choice of steel versus iron follow.

INSTALLATION

Various options exist for the installation of mooring bollards and cleats. The most common method is utilizing cast-in-place embedded anchors. Alternate methods include through bolting with cast in pipe sleeves, or epoxy-in anchors for retrofitting existing structures. Cast-in anchors or pipe sleeves should be set in place with the aid of a template or setting frame which will locate the anchors within the proper tolerances. For installations where the bollard is to be set into a recess cast into the concrete.

Always follow installation procedures supplied by Florescence when installing our bollards as each installation may be unique and require special instructions. Particular attention should be paid to the torque values recommended for each installation.

COATING

Coatings are an essential part of the system as it prevents excessive corrosion that can weaken a bollard. This is particularly significant for cast steel bollards, which are less corrosion resistant than ductile iron bollards. Virtually any coating requested can be applied, but some attention to the abrasion resistance of the coating should given as the direct contact and movement of the mooring lines will result in accelerated wear of any coating. Bollards can be supplied fully painted from our factory or with an easily removable rust preventative primer that allows surface preparation and coating on-site after installation. Traditionally, cleats are supplied hot dip galvanized, but can also be supplied painted if requested.
