Abstract
A container for maintenance capsule as a component of a maintenance system for an offshore wind turbine maintenance program. The container transports tools, parts and maintenance personnel to and from respective wind turbine towers. The container is seaworthy, watertight and floatable, and can be loaded on a maintenance vessel which carries the container to and from a wind turbine tower.
Claims12
A container for use in an offshore wind turbine maintenance program, said container being constructed to safely survive being disposed and briefly submerged in the sea and protect maintenance people and cargo located in said container, said container comprising:
- an outer wall for said container, said outer wall being seaworthy and watertight for rendering said container floatable;
- a personnel compartment within said outer wall for holding at least one maintenance person;
- a cargo compartment within said outer wall for holding cargo;
- a watertight bulkhead separating said personnel compartment from said cargo compartment;
- at least one access door assembly for opening and closing said outer wall to said personnel compartment for enabling at least one maintenance person to enter and exit said container;
- a truncated conical shell including a forward truncated end portion and a rearward truncated end portion of said container, said truncated conical shell further including a forward endmost section and a rearward endmost section;
- and
- a capsule attachment line holding-and-releasing apparatus disposed in one of said endmost sections for selectively holding and selectively releasing a capsule attachment line from said receptacle for selectively enabling said at least one container to be moved to or from a wind turbine tower, said holding-and-releasing apparatus including:
- a receptacle for receiving and discharging a capsule attachment line;
- and
- a capsule attachment line engaging apparatus for being secured to a capsule engagement line.
A seaworthy, watertight, floatable container for use in an offshore wind turbine maintenance program, said container being able to safely survive being disposed in the sea and protect maintenance people and cargo located in said container, said container including:
- at least one access door assembly for enabling cargo and any maintenance persons to be loaded and unloaded from said container, a capsule attachment line holding-and-releasing apparatus for selectively holding and selectively releasing a capsule attachment line for selectively enabling said at least one container to be moved to or from a wind turbine tower, and a towrope storage compartment for storing a towrope for being grasped to enable the pulling of said container;
- a homing boat for optionally taking a part of said towing rope to a maintenance water vessel;
- and a launch tube for storing said homing boat.
A seaworthy, watertight, floatable container for use in an offshore wind turbine maintenance program, said container being able to safely survive being disposed in the sea and protect maintenance people and cargo located in said container, said container including:
- at least one access door assembly for enabling cargo and at least one maintenance person to be loaded and unloaded from said container;
- a capsule attachment line holding-and-releasing apparatus for selectively holding and selectively releasing a capsule attachment line for selectively enabling said at least one container to be moved to or from a wind turbine tower;
- and
- a truncated outer shell defining the exterior of said container, said truncated outer shell having a nose portion, wherein said capsule attachment line discharge port is located in said nose portion.
