A system is provided that includes a print head, a conveyance system, an encoding sensor, and at least one processor. The print head defines a print zone, and is configured to print on objects within the print zone. The conveyance system passes through the print zone, and is configured to translate a pallet through the print zone. The encoding sensor is disposed proximate to the conveyance system, and is configured to be oriented toward the pallet and to acquire positional information regarding the pallet. The at least one processor is operably coupled to the print head and the encoding sensor, and is configured to: receive the positional information from the encoding sensor; determine timing information corresponding to when a substrate disposed on the pallet will be in the print zone; and control the print head to print on the substrate when the substrate is in the print zone.

A method for mitigating the effects of cable wear in an active heave compensated hoisting system of an offshore vessel in a locked to bottom mode of operation is disclosed. The method comprises supporting an upper end of a string which is connected to a subsea well from a travelling block of the hoisting system, wherein the travelling block is suspended from a crown block via a cable. The method further comprises operating an active heave compensation system to control a drawworks of the hoisting system to pay in and out the cable to compensate for motion of the offshore vessel and maintain a target overpull in the string. The method further comprises adjusting a ballast system of the offshore vessel to vary the draft of the vessel, and controlling the drawworks in accordance with the variation in the draft of the vessel to cause a length of cable to slip through the hoisting system and maintain the target overpull in the string.

A remote anchoring apparatus is mad of two elements, an anchoring element and a connecting element. The connecting element is formed to be guided into a respective space made in the anchoring element and be locked in it. The connecting element may be guided towards the anchoring element by a flexible pulling means such as a rope pulled through the anchoring element.

A motion compensating crane for use on an offshore vessel having a hull with a design waterline, wherein the crane includes a revolving superstructure, a main boom mounted to the revolving superstructure and pivotally connected at an inner end thereof about a substantially horizontal boom pivot axis to the revolving superstructure, the main boom having a tip end remote from the inner end, a main boom luffing assembly adapted to set an angle of the main boom relative to the superstructure within a main boom working angle range, a rigid jib frame pivotally connected to the tip end of the main boom about a substantially horizontal jib frame pivot axis, and a level setting assembly adapted to set the rigid jib frame in a levelled position whilst the main boom has an angle within the main boom working angle range. The rigid jib frame is provided with a set of parallel X-direction tracks which are substantially horizontal in the levelled position of the rigid jib frame. The crane further has a mobile carrier supported by the X-direction tracks and movable by a motor powered X-motion displacement actuator assembly. The mobile carrier is provided with one or multiple parallel Y-direction tracks and a mobile jib hoist cable suspension member is supported by the one or more Y-direction tracks and movable relative thereto.

A hoisting system is for hoisting a vertically-suspended object. The hoisting system has a winch having a winch drum with a hoisting rope. A first part of the hoisting rope has a first diameter and a second part has a second diameter being larger than the first diameter. The first part is connected with a first end of the second part. The first part is an inner part on the winch drum when the winch drum is completely wound. The second part has a further end that is connectable to the object for hoisting the object. A ratio between the first diameter and the second diameter is such that the minimum breakable load of the first part differs less than a factor of four from the minimum breakable load of the second part, and preferably less than a factor of three. A corresponding method is disclosed.

A system and method of transporting and unloading a load from a floating container that includes placing a load on a floating container at a first location, wherein the load is a mixture of solid material and liquid; moving the floating container with the load on a body of water from the first location to a remote second location; positioning the floating container so that a crane at the second location is within reach of the load; positioning a dewatering unit at the second location proximate the crane; unloading a quantity of the mixture of solid material and liquid from the floating container with the crane; depositing the quantity of the mixture of solid material and liquid into the dewatering unit; and dewatering the quantity of the mixture of solid material and liquid with the dewatering unit.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames arc spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.
