The concept of integrating a total system has been around for centuries. It has been proven to be a very cost effective reduction of operations ensuring larger profit margins. In designing the SEAT (Self Elevating Accommodations Tower) all concepts were taken into account, from the efficiency of a motel and the transport of containerized cargo all over the world to the simplicity of an air freight system.The main concept was to reduce the number of costly vessels that would be needed to fill the requirements and improve on the use of the vessels that would be employed.
It is much less costly to start with a new idea than to try to re-fit or change an existing vessel to the needs. Redesign, approvals, taking the vessel out of its intended service to do the changes, and the labor to remove structures in the way or to re-fit current structures is time-consuming, expensive and, often, does not completely address the project demands.
The SEAT, coupled with the Mothership accomplishes such a goal. For example, a request to house two thousand workers in an oil field could be met using liftboats with temporary quarters on deck (provided the USCG would permit it). You would need 8 of the largest liftboats in existence, which means you would have 8 crews to pay as well as other support vessels and staff. With the IMP system, you would use 8 SEATs and one mothership. That means only one marine crew to pay, only one vessel to support, and the needs of two thousand workers are met. The concept is quite simple - lower the cost of building the accommodations, lower the cost of operating the accommodations, add a percentage of the savings back into the mothership and service all the needs.
The next step is to consolidate the work of the vessel. This is accomplished by designing the housing units to employ containers for deliveries of supplies, water, fuel, sewage and storage. It is much faster to load a container onto a deck than it is to put supplies into a basket and hoist it up. The use of containers for water, fuel and sewage also expedites the process. The time (and attendant danger) taken to pump the liquids in and out of the tanks consumes costly payroll. To just remove and replace the entire unit at site, then have less costly employees at the land based operation remove or replace the liquids would be the first cost savings but it goes further than that. The cost of equipment, repairs to the pumps and equipment and the maintenance to the vessel systems further reduces the profit margin. With the containerized system that cost factor is added to the profit margin.
The accomplishment is simple, design a motel on legs with all the amenities and cost savings of land base operations. Then design a vessel that will service everything from laying the foundation to delivering the groceries. This is what you are about to review: an integrated SEAT/Mothership system.
The rendering below shows the diversity of the SEAT. The first setup (top left) is a permanently installed unit, the leg system employs helical anchors to “screw” it to the bottom and can be used in water depths of up to 300’; the second setup (top center) is a semi submersible unit that can be towed to site, the unit is employing a helical anchor system that the SEAT can be moved about on can be used in water depths of up to 1600’; the third setup (top right) is a pontoon hulled unit that also can be towed to site, the unit is employing telescoping leg system that employs helical anchors to “screw” it to the bottom can be used in water depths of up to 180’.
