A safety system for transferring a load from vessel to a jetty or other surface. The system includes a rod assembly having a movable proximal end, and a distal end and is about parallel to a surface. The proximal end of the rod assembly is anchored on the vessel. A first carabiner is coupled to the distal end of the rod assembly. A first pulley is detachably coupled with the first carabiner to support movement of a passing rope. A descent control device assists in managing movement of the rope from the vessel to the surface. The descent control device is configured with a stainless steel anchor ring attached or improvised anchor point using a wire rope sling to the vessel in order to create a primary anchor point. A fourth carabiner allows a first knotting of partial first end of rope. A chair assembly is coupled to the fourth carabiner to a pre-defined distance from the first end of rope. A hook unit is configured with the fourth carabiner to allow a second knotting of the first end of the rope and is detachably coupled to secure a harness in order to safely transfer the load from the vessel to the surface.

A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

A method for transporting a parcel comprises a marine unmanned vehicle (MUMV) receiving a waterproof tote, coupling the tote to a tether, and towing the tether and the tote, with the tether floating on the transport waterway and the tote immersed in the the transport waterway, to a delivery location. The method can include an MUMV receiving the tote from, and/or delivering the tote to, an aerial vehicle. An unmanned water transport system (UWTS) comprises an MUMV, a floating tether, and a waterproof tote containing a parcel for transport on a transport waterway. The MUMV and tether are configured to tow the tether, with the tether floating on the transport waterway, and the tote coupled to the tether and immersed in the water of the transport waterway, to transport the tote from a source location to a delivery location on the transport waterway. The UWTS can perform the method.
