A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.

An improved method and apparatus for removing metal cuttings from an oil well drilling mud stream provides a magnetic body or “ditch magnet” having end plates that extend radially and circumferentially from the magnetic body, the plates being positioned at end portions of the magnetic body. A third plate in the form of a wiper is used to dislodge metal cuttings and other metallic material from the magnetic body after the magnetic body has accumulated such metallic parts. One of the end plates can be removable to facilitate a complete scraping or wiping of the metallic parts from the metallic body by the wiper plate.

A method for transferring fluids and personnel between a work vessel and an offshore marine platform includes the placement of an elongated self-supporting frame between the work vessel and the marine platform. A walkway is provided on the frame. Pipe racks are provided on the frame, one pipe rack on each side of the frame so that a pair of pipe racks are on opposing sides of the frame. Hand rails are mounted in between the walkway and each pipe rack. A fluid holding pan extends under the walkway and the flowlines. In this fashion, fluid that falls from either a pipe rack or a walkway to the pan can travel through a common drain or collection area.
