Close co-operation with classification societies and maritime authorities, combined with innovative design, quality products and worldwide lifecycle support, makes MacGregor the perfect partner for your marine and offshore projects.


The valuable connection Since 1986 MacGregor has developed and s­ upplied Pusnes loading systems for both ­simple and sophisticated operations. The new range of ­products is based on innovative and proven t­echnology and meets customers’ and authorities’ requirements for operational and environmental safety. MacGregor believes that commitment to continued research and development is the key to maintaining a strong position in the market. Our experience, ­engineering competence and focus on people are just some of the reasons for choosing MacGregor to supply Pusnes offshore loading systems.

In-house technical expertise provides customers with safe, integrated and cost-effective solutions. The c ­ ontinued success of our loading systems depends on our commitment to deliver high quality products which are operationally safe and environmentally sound.

Our Pusnes loading systems ensure safe and ­efficient offshore transfer of crude and other products. The loading scenarios involve various types of ­offshore production and storage facilities such as FPSOs, FSOs, CALM buoys, loading towers and fixed ­platforms. The transfer of oil from these facilities to a shuttle tanker or tanker of opportunity is carried out via the Pusnes offloading system and the Pusnes bow loading system.

Our dedication to safety is verified by our long track record for the supply of systems with virtually no i­ncidents leading to human injury. Various types of safety features are included in the equipment design and contribute to achieving the high level of safety, pollution avoidance, e.g.:

MacGregor has a strong history of innovation and execution excellence of Pusnes loading systems. State-of-the-art concepts for challenging off-loading and bow loading projects have placed us at the forefront of the industry.

Bow loading system The Pusnes bow loading system enables a shuttle tanker to safely and ­efficiently load oil from an ­offshore production or s­ torage facility. The bow ­loading system consists of two integrated systems.

The hose handling system A 20” bow loading coupler is located forward at the centreline of the ship. The coupler receives the hose end from the offloading vessel/platform (FPSO, FSO). A vital part of the system is the Pusnes moment free bow loading coupler which allows the coupler to follow the movement of the hose. The system includes a hose winch for pulling in and handling the hose during the connection and disconnection phases.

The hawser handling system A roller fairlead and a chain stopper located on the platform deck are operated together with a twin drum traction winch for mooring purposes during tandem loading. The chain stopper is a hydraulically operated, self-locking type, and can be released under full design load. Aft of the chain stopper is a guide roller with a built-in load cell which operates together with a traction winch. The system also includes a storage reel or bin for storing the messenger line during loading.

Offloading system An offloading system enables an offshore unit to offload oil to a shuttle tanker or tanker of opportunity. The system consists of two integrated systems.

The hose handling system The hose handling system comprises of various ­components that handle the hose during offloading and store the hose between loadings. The hose can be stored on a reel on deck, or on a chute along the deck. Simple systems have the hose floating in the sea between loadings.

The hawser handling system The hawser handling system is a mooring system with the purpose of maintaining the tandem-moored vessel at a safe distance during loading operations. The hawser is attached to a releasable hawser-handling winch which combines mooring, handling, storage and emergency release functions into a single unit. After the offloading operation has been completed, the releasable hawser handling winch is used for storing the hawser complete with thimbles, chafing chain, messenger line and forerunner line. All operations are handled without any manual handling of shackles and hawsers.

Exploring the Arctic and s ­ ubarctic regions MacGregor successfully provides functional and reliable Pusnes systems for rough and extreme weather conditions. As development of the arctic continues, the need for specialised equipment for these harsh and environmentally vulnerable areas becomes significant. The majority of today’s shuttle tankers operate in the extreme weather conditions of the North Sea or in the arctic north of Russia, where reliable systems are a must. Customers continue to depend on us to develop and deliver equipment that meets these demands. With over 100 years of experience supplying Pusnes deck machinery designed for extreme conditions, we have acquired extensive expertise and skill, which is reflected in other innovative products such as our Pusnes arctic crane offloading system.

The Pusnes arctic crane offloading system was developed for offloading oil to dedicated shuttle tankers operating in arctic ­conditions. The system is designed for the following loading scenarios: • Icy conditions in pack ice with hose above ice and minimal changes in position • Open water in summer season with dynamic loads and frequent vessel movements The crane is designed for long-term operation and stowing in harsh arctic and corrosive offshore/marine environments.

Arctic and subarctic deliveries include mooring and loading systems to the northern territories of Canada and Russia.

Some of the first references for the supply of Pusnes deck winches are for the polar vessels Fram and Maud, used by Roald Amundsen d ­ uring his polar expeditions in the early 1900s (including his historic expedition to the South Pole in 1910-1912).

R&D Offshore loading Oil companies and ship owners appreciate unique experience when evaluating new offshore loading concepts for LNG and crude oil. MacGregor regularly participate in early phase studies as well as in detailed development of tailor-made solutions and new concepts. Below are described three major new concepts.

Extended Envelope Offloading The ultra low risk offloading solution for GBS (Gravity Based Structure) or spread moored storage units. Main features: • Minimum risk for collision, oil spill and downtime • Standard DP2 shuttle tanker

• Large vessel separation; 250 m, optional mooring lines • Large operation envelope/safety zones • 360° tanker heading possible • Suitable for various hose configurations; submerged hose, floating hose and semi buoyant “Lazy W” hose for shallow waters

LNG Offshore Tandem MacGregor is a key partner in the OCT Group (Offshore Cryogenic Transfer), headed by OneSubsea. OCT has developed the system for offshore loading of LNG in a tandem configuration, a system based on the tandem ship-to-ship configuration that has been successfully employed for more than 20.000 offshore crude oil loading operations over the past 30 years.

Main features: • Safe offshore transfer of LNG in harsh environment • Quick Connect & Disconnect • Vessel separation; 90-115 m • Moment free flexible pipe suspension • 3 flexible pipes; 2 for LNG transfer and 1 for vapour return • DP2 LNG Carriers including an LNG version of the world renowned Pusnes bow loading system

LNG Offshore Side by Side A concept for side by side transfer of LNG to standard LNG carriers in harsh environment. Operating limits are increased when compared to conventional marine loading arm systems. Main features: • Increased vessel separation; 20 meter • Operation in Hs 3,5 m • Augmented offloading rate with 16” composite hoses • Quick Conntect & Disconnect
