Safe and Secure

MacGregor believes that commitment to continued research, studies and development has strengthened our position as a leading international company on a worldwide basis. Exploration and production in harsh climate areas require innovative thinking. Together with our proven technology we meet new challenges and provide equipment designed for safe and secure operation under the most demanding scenarios.

Our mooring systems on board vessels in hurricane affected areas, such as the Gulf of Mexico, have on several occasions sustained the brutal forces these severe weather conditions can deliver.

Innovative and proven technologies at competitive prices, as well as proximity to the market are both important factors for ensuring future competitiveness.

We have worldwide production capabilities that allow timely support of quality products to an ever-changing global market.

MacGregor has supplied Pusnes offshore systems since 1968 and is recognised worldwide as an innovative designer and manufacturer of on-vessel mooring equipment for the offshore market. Different types of winches, fairleads and chain stoppers have been developed over the years.

Pusnes™ RamWinches installed on board theNansen, the world’s first truss spar. The winches are designed to endure submerged conditions prior to upending.

Pull-in Winches and EquipmentPull-in winch is a general term used to describe the various types of winches involved in pull-in operations, such as the riser pull-in and mooring line pull-in. Various ancillary equipment, for instance trolleys and turndown sheaves are often involved in operations such as the riser pull-in.

Mooring WinchesPusnes mooring winches have evolved from steam-driven ship winches back in the late 1800s to the state-of-the-art electric and high-pressure hydraulic winches of today. Our offshore product range comprises anchor windlasses, chain jacks, traction winches, combination winches and rope/wire winches. Custom control and monitoring systems provide precise handling and management of a single winch or an integrated system of winches.

The windlass consists of four cable lifters with a single electric drive/gearbox and two fail-safe band brakes per cable lifter. Brakes can be released using stored energy (accumulator) in an emergency situation.

Chain jacks - Pusnes™ RamWinches became a popular choice for the mooring of production vessels after their introduction in 1997. Compact size and low weight contributed to this winch being used on the majority of all spar platforms in the Gulf of Mexico, and increasingly for semis, as pictured here on board the Horn Mountain. Most of the spar Pusnes™ RamWinches are designed to endure submerged conditions during transportation of the hull (up to several months).

The movable windlass is a concept designed to operate multiple mooring lines within the same area. Normally, one windlass skids along a special foundation to operate one mooring line at a time. Photo depicts a movable windlass designed for the Goliat FPSO in the North Sea.

In addition to movable windlasses, MacGregor Pusnes has designed movable chain jack mooring systems. This is a graphic representation of one of four mooring clusters on an FPSO.

Fairleads and Chain StoppersMacGregor has an excellent reputation for supplying high-quality long-life Pusnes fairleads and chain stoppers. They are designed for operation in all climate conditions and for the harsh environments both above and under water.

Our latest fairlead designs include attachments that allow for the removal and re-installation of fairleads underwater, at the vessel’s offshore location. We have also designed the special tools needed for this operation.

In recent years, a popular choice for offshore production mooring has been the innovative Pusnes™ fairlead chain stopper. This unique fairlead combines the flexibility of a flag-type fairlead with the holding ability of a chain stopper.

Pusnes™ chain stoppers come in various types and sizes. Photo displays a version delivered to the Greater Plutonio FPSO.

The compact design, low weight and hull-mounted location contribute to lower topside deck weight. This unique design allows for chain locking in a long pivoting stopper arm on the side of a vessel’s hull, below the waterline. This constrains maximum loads to a limited area. Additionally, chain wear, static and fatigue stresses are greatly reduced.

Pusnes™ eccentric chain fairleads mounted on the hull of BP’s Greater Plutonio FPSO. The FPSO was installed off the coast of Angola in 2007. This type of fairlead has also been a popular choice for the many spar platforms found in the Gulf of Mexico.

Pusnes™ eccentric chain fairlead. Fairleads are known for their robustness and they are virtually maintenance-free. Recent designs allow for installation/replacement without the use of a diver. The eccentric chain fairlead has become the preferred choice for both drilling and production vessels. These can also be designed for wire or chain/wire combination. Photo from Visund production platform.

Pusnes bull’s eye fairlead™ is the grandfather of fairleads for offshore drilling rigs and accommodation units. Although we see a shift towards eccentric chain fairleads, bull’s eye fairleads still serve a purpose when the mooring line needs to be held close to the hull. These can be designed for wire, chain or chain/wire combination. Image shows the design of a fairlead for 90mm wire for Prosafe’s Safe Boreas.

The Pusnes™ bellmouth chain stopper provides a simple means of chain holding in benign areas where the mooring line can run straight off the deck. The stopper is designed for the full breaking load of the chain. In addition, a mobile tensioning device has been designed to move from stopper to stopper. A portable hydraulic power unit can be delivered to power the tensioning device.

Power Supply and Control SystemsBoth high-pressure hydraulic and AC/DC electric power can be used to drive the various types of offshore mooring winches.

The hydraulic power units (HPU) are of a state-of-the-art design that provides a dependable source of power and performance in harsh and varying offshore environments. High-pressure hydraulics in a “ring main” system enables use of smaller pipe diameters and shorter pipe lengths.

Pusnes™ offshore winches are normally controlled by modern programmable logical controllers (PLC) in separate cabinets, where all status/alarm messages can be transferred to a designated control room. Graphic terminals with clear color displays act as an interface between operator and equipment.
