BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to marine vessels, and more particularly, to a boat which is adapted to receive a variety of modular pods, each pod being equipped for a particular application.

2. Description of the Related Art

The use of marine vessels to accomplish a variety of tasks in a marine environment is known in the art. For example, in the support operations of large maritime vessels of the type used in activities such as offshore oil drilling, military naval activities, seafaring cargo transportation, etc., it is known to utilize smaller vessels to perform certain support tasks, such as transportation of personnel, cargo, and equipment to and from the large vessel, search and rescue activities, fire prevention and suppression, emergency medical response, security support, spill containment, emergency evacuation, etc. Typically, the smaller support vessels used in these types of support operations are each designed and equipped for a particular type of activity, and are often designed to remain in a hoisted, stored, or otherwise idle configuration on or near the large vessel when the particular activity for which the support vessel is designed is not being performed.

In several marine support operations, such as those support operations involving security and/or emergency response, rapid deployment of a support vessel which is properly equipped for a particular support operation is important. However, in environments in which properly equipped support vessels are kept in a stored condition on a large vessel, and particularly in environments in which the vessels are stored in a hoisted, stored position above the water level, such rapid deployment of a support vessel is often delayed by the need to first configure the support vessel to a usable condition, for example by removing the support vessel from the hoisted position and placing the support vessel in the water. In certain situations, applicable laws governing safety protocol during removal of a hoisted support vessel from the hoisted configuration and placement of the support vessel into the water prohibit such actions from being performed while persons are aboard the support vessel. Thus, in several applications, it may be necessary that configuration of the support vessel to a usable condition is performed prior to occupation of the support vessel by people, such as for example operators of the vessel and/or emergency response personnel, thereby resulting in additional delay in deployment of the support vessel. In other situations, applicable laws may prohibit the removal of a hoisted support vessel from the hoisted configuration and placement of the support vessel into the water while the support vessel carries certain equipment, such as for example pressurized gas tanks or other equipment which may pose a hazard if handled improperly. In these applications, it may be necessary that configuration of the support vessel to a usable condition be performed prior to equipping the support vessel with the equipment necessary to perform the function of the support vessel.

In several environments, a large maritime vessel may include and/or carry a number of support vessels, with each support vessel being equipped to perform a specific support task. However, due to space restrictions aboard the large maritime vessel, it may be implausible for the large vessel to include and/or carry sufficient numbers of support vessels equipped to properly perform each support task which may be required. For example, an offshore oil-drilling platform may house a support vessel equipped for use in controlling oceanic oil spills, a support vessel equipped for use in suppressing fires at sea, and a support vessel equipped for medical emergency response and/or evacuation. In this example, when a situation arises in which a particular specialized task, for example fire suppression at sea, is to be performed, only the support vessel equipped for use in fire suppression may be deployed, while the rest of the support vessels may remain undeployed on the large vessel. In the event of a large fire, the single deployed support vessel equipped for use in suppressing fires may be insufficient to effect proper fire suppression.

In light of the above, there is a need in the art for a marine support vessel having quickly interchangeable modular sets of equipment, with each set of equipment being suitable to equip the support vessel for use in performing a specific support task, such that the modular equipment sets allow the support vessel to be quickly and properly equipped and/or reequipped for use in one of a plurality of support tasks.
