NORSOK Personnel Transfer Basket 1145-4-N

NORSOK R-002 is the Norwegian standard for lifting equipment on the continental shelf. The 1145-4-N is approved according to the 2017 edition, which among other things requires shock-absorbing seats for the passengers.

DNV Type Approval BGN23-9728 according to NORSOK R-002:2017+AC2019, DNV Type Approval TAS00001AD (DNV-ST-0378, EN 14502-1) and an ABS Product Design Assessment. All of them can be opened under Certificates on this page.

From −50 °C to +70 °C.

Mean wind up to 10 m/s (NLS) or 17 m/s (LS), and significant wave height up to 3 m (NLS) or 6 m (LS), in daylight.

Four seated passengers. The rated capacity (SWL) is 560 kg, and the basket is test loaded with 1,120 kg (2 × SWL).

One person on a stretcher, fastened according to the stretcher instruction, plus two other persons. No modification of the basket is needed: the stretcher goes straight in, so an injured person can be evacuated quickly.

The 1145-4-N protects the passengers against a vertical impact of 4 m/s and a lateral impact of 2 m/s, with full payload. The seats sit on suspended pedestals, and the orange PUR fender takes the lateral impact.

ALARP (as low as reasonably practicable) is a central principle in offshore risk assessment. On the Norwegian continental shelf it is reflected in section 11 of the Framework Regulations. The basket reduces the main risks in a crane transfer: impact protection up to 4 m/s vertical and 2 m/s lateral with full SWL, two independent slings that can each carry the full load (safety factor ≥ 10), three lifting points on the Top Eye, and a stretcher that goes straight in without modification of the basket. The 1145-4-N is approved according to NORSOK R-002:2017, certified by DNV and has an ABS Product Design Assessment. The seats absorb the vertical shock at landing.

Yes. The basket protects the passengers against a lateral impact of 2 m/s, with full payload. The orange PUR fender takes the hit if the basket swings into the side of the vessel or a platform leg.

The 15-year warranty covers the stainless steel frame. Any warranty is subject to the following conditions: compliance with the inspection and re-certification conditions as stated in the Safe Transfer Guidelines for all Safe Transfer basket models as adjusted from time to time, service is conducted by authorized personnel, and that the basket has not been damaged.

Yes. The 1145-4-N is a sit-down basket, not a traditional standing basket. Each of the four passengers sits in an individual seat with a fastened seat belt, on a suspended pedestal, with handlebars in front of the seat.

Yes. The 1145-4-N is self-righting. Buoyancy tanks inside and outside the frame keep it floating in an upright position with its full payload, with the passengers in their seats above the surface. All persons must still wear a work life jacket or a survival suit with buoyancy.

The frame is AISI 316L stainless steel and non-collapsible, 100 % made in the EU and welded to procedures approved by DNV. The floor is 5 mm aluminium plates with a non-skid surface.

From the stainless Top Eye with 3 independent lifting points, in two independent slings: a lifting sling and an elastic compensator. Each of them can carry the basket with its full payload. Safety factor ≥ 10, and the shackle pin must be at least 25 mm.

It floats in an upright position with its full payload. All persons must still wear a work life jacket or a survival suit with buoyancy.

Height 3,350 mm and diameter 2,600 mm. Self-weight 670 kg, total weight 1,230 kg.

A visual check before each use, an inspection by a competent person every 6 months, and an annual inspection by a workshop approved by Safe Transfer or DNV. The compensator is replaced every 12 months and the lifting sling at least every 5 years.

The stainless steel structure has a lifespan of more than 30 years, and there is no limit on the number of lifts.

Yes. All entrances, exits and the floor have a non-skid pattern, and the rope sections close with fast click-buckle straps, so passengers can get in and out quickly and safely. Speed never replaces safety.

Yes. The design is type approved by DNV, based on prototype load tests witnessed by DNV. The design also has an ABS Product Design Assessment. Every basket is load tested before it is taken into use, according to DNV-ST-0378, and the welds are inspected with non-destructive testing. The impact protection is 4 m/s vertical and 2 m/s lateral, with full payload.

Crane transfer of personnel between a vessel and an offshore installation. It is type approved by DNV according to DNV-ST-0378 and EN 14502-1, the European standard for suspended baskets for lifting of persons. The design also has an ABS Product Design Assessment.

The 1145-4-N is built for maximum personnel safety. Every passenger sits in a shock-absorbing seat with a fastened seat belt, the basket has impact protection of 4 m/s vertical and 2 m/s lateral with full payload, two independent slings with a safety factor of at least 10, and it is self-righting in the water. It is approved by DNV according to NORSOK R-002:2017, and every basket is load tested before use.

Each seat sits on a suspended pedestal that absorbs the vertical shock, and the passengers are held in place by seat belts. The orange PUR fender protects against harmful deceleration, and the elastic compensator absorbs the wave motion at landing. The vertical impact protection is 4 m/s with full payload.

It is the Safe Transfer basket with the highest level of passenger protection. It combines individual shock-absorbing seats with seat belts, impact protection of 4 m/s vertical and 2 m/s lateral with full payload, two independent slings with a safety factor of at least 10, a top net, a self-righting design and room for a stretcher. It is approved by DNV according to NORSOK R-002:2017.
