Bellingham Marine’s company strategy is fairly simple; provide each client with a solution that provides the best value for their specific project and criteria. In order to find a balance between price and performance, each project must be looked at through its own unique lens.
The company relies heavily upon the expertise of its employees, its experience in the industry, and its network of outside professionals to provide each client with a best value option.
Innovation is embraced as a means to achieve “best value” rather than a goal in and of itself. It is this focus on value and ability to provide innovative solutions that allows Bellingham Marine to excel in its niche market and to be comfortable and successful in taking on unique, one-off projects.
In 2013, Bellingham Marine was approached by a major supplier of high quality construction aggregates. The company was looking for an innovative solution for mooring its Panamax bulk carriers at its new import terminal at the Port of Long Beach in California. The existing berth structures at the site were designed for barges and would not work for what the company needed. They needed a solution that would allow them to moor mid-sized bulk carries and support an efficient off-loading operation.
If you work in the marina industry it is important to understand the difference between freeboard and live load capacity and how the two affect the stability and use of a floating dock.
Freeboard, in simple terms, is the height of a dock’s deck above the water.
Live loads are variable and include all unfixed items on the dock such as people and personal items. Basically live loads are how much weight you want a dock to support without sinking.
The two are related. The more live load placed on the dock the greater affect that extra weight has on how high the dock floats in the water.
This is where the discussion gets more technical. All things float based on the concept that they displace the water they are floating on. Salt water weighs approximately 64 pounds per cubic foot. So if we divide 64 by 12 we get 5.33 pounds, which means, if we’re using round numbers, if 5 pounds of pressure is applied to the top of an object, measuring one square foot, floating in salt water, the object will sink 1 inch.
With that simple concept in mind, we can show how live load capacity affects the freeboard of the two most common types of floating dock systems. Continue Reading…
